If you're thinking about buying a wax 3D printer, it's important to understand these key technical parameters. This article focuses on SLS wax 3D printers, analyzing the key technical parameters of laser power and wavelength, layer thickness and accuracy, and temperature control of the build platform, and describing how they affect the printing results, wax quality, and suitability for different application scenarios, so that you can accurately assess the performance of the printer according to your own needs and make a more informed purchasing decision.

Effect of laser power and wavelength

laser power

• Sintering capacity correlationLaser power is a key parameter for SLS wax 3D printers and directly determines the effectiveness and efficiency of the wax sintering process. Higher laser power allows the wax particles to melt and bond together faster, making it possible to quickly build larger or thicker structures. For example, in the manufacture of wax molds for large industrial parts, sufficient laser power ensures that the wax powder is fully sintered in a short period of time, increasing the printing speed. However, if the laser power is too high, this may lead to overburning of the surface of the wax mold, e.g. scorching, deformation, etc., which affects the quality and subsequent use of the wax mold. On the other hand, too low a laser power may not allow the wax powder to melt completely, resulting in a weak sintering and a loose structure of the wax mold, or even damage during subsequent handling or processing.
• Adaptation to different materials: Different types of wax materials have different requirements for laser power due to their different physical properties such as melting point and thermal conductivity. For wax powder with high melting point and relatively hard texture, higher laser power is often needed to realize good sintering; while wax powder with lower melting point and easier melting can use relatively low laser power. Therefore, the selection of wax powder materials needs to be considered in conjunction with the laser power range of the printer in order to achieve the best sintering results.

laser wavelength

• Material Absorption Properties: The wavelength of the laser also plays an important role in the printing process by influencing the degree of absorption of the laser energy by the wax material. Different wax materials have different absorption efficiencies at specific wavelengths. For example, some wax materials may absorb laser energy better at wavelengths in the near infrared (NIR) region, and under the irradiation of the laser at this wavelength, the laser energy can be efficiently converted into thermal energy, resulting in a good sintering. If the laser wavelength does not match the absorption characteristics of the wax powder material, even if the laser power is sufficient, it is difficult for the wax powder to fully absorb the energy for melting and sintering, which can lead to printing failure or poor quality of the printed wax model.
• Application Scenario Differences: In practical application, according to different use scenarios and requirements on wax mold performance, sometimes it is also necessary to choose a suitable wavelength of laser. For example, in the printing of jewelry wax molds, which requires high precision and high surface quality, a specific wavelength of laser may be selected, which can make the wax powder sintered finely and uniformly, and reduce the surface defects due to uneven energy absorption; while in some industrial wax molds manufacturing scenarios, which require lower precision and pay more attention to productivity, the laser may be selected according to the common wavelengths of the wax powder material, which are generally suitable for the wax powder to achieve fast and stable printing. realize fast and stable printing.

Print Layer Thickness and Accuracy Analysis

print layer thickness

• Impact on model refinement: The print layer thickness is the thickness of the wax mold layer that is formed when each layer of wax powder is sintered during the SLS printing process. Smaller layer thicknesses result in finer details and smoother surfaces. For example, when printing wax models of artistic sculptures with fine textures or intricate jewelry wax models, a layer thickness of a few tens of microns can clearly reproduce details such as tiny grain lines and thin-walled structures in the design model. On the contrary, a larger layer thickness can speed up the printing speed, but it will lead to obvious stepped textures on the surface of the wax model, reducing the fineness of the model, which is not suitable for some products with high demands on appearance and precision.
• Trade-offs with print speed: There is often a trade-off between accuracy and speed when choosing a layer thickness for printing. Thinner layer thicknesses mean that more layers are needed to build the entire wax mold and print times increase significantly, while thicker layer thicknesses reduce the number of layers and speed up the process, but at the expense of some accuracy. In actual production, the layer thickness should be determined according to the specific product requirements and the urgency of the production task. For example, for mass-produced industrial molds that do not require particularly high precision, the layer thickness can be increased to improve production efficiency; while for customized, high-value fine wax molds, a smaller layer thickness is preferred to ensure quality.

Precision Analysis

• Dimensional accuracyDimensional accuracy is a function of how well the printed wax model matches the design model in terms of size, and is affected by a number of factors including the accuracy of the laser scanning system, the positioning accuracy of the mechanical moving parts, and the shrinkage of the wax powder material during the sintering process. High precision printers are able to control the dimensional error within a very small range, which is crucial for wax molds that need to be precisely matched with other parts, such as wax molds for precision casting and wax molds for dental restorations, or else the cast metal parts may not be able to be mounted properly or the medical restorations may not be effective.
• Shape AccuracyShape accuracy is related to the ability of the wax model to accurately reproduce the complex shapes and geometrical structures of the design model. Since SLS constructs wax molds by layer-by-layer sintering, it is easy to have accuracy problems in some parts with special shapes such as overhanging parts, thin walls, inner corners, etc. For example, the overhanging parts may need to be supported, and if the support design is not reasonable or not handled correctly after removing the support, the shape accuracy of the part may be affected. In addition, the planning of the laser scanning path and the uniformity of the wax powder will also affect the shape accuracy. Ensuring a good shape accuracy will ensure that the wax model meets the expected function and appearance requirements in the subsequent applications.

Temperature control for building platforms

Initial temperature setting

• Wax powder spreading uniformityThe initial temperature of the construction platform has an important influence on the uniformity of the spreading of the wax powder on the platform. A suitable initial temperature enables the wax powder to spread better during the laying process and avoids localized piles or vacancies. For example, when the platform temperature is slightly higher than the fluidity temperature of the wax powder at room temperature, the wax powder can be evenly spread on the platform like fine sand, providing a good starting condition for subsequent laser sintering. If the platform temperature is too low, the wax powder may not be able to spread out smoothly, resulting in uneven thickness of each layer of wax powder, which in turn affects the quality of the whole wax mold; whereas too high a platform temperature may cause the wax powder to be partially melted and sticking before it is spread out, which likewise destroys the molding effect of the wax mold.
• Quality of the first sintered layer: The initial temperature also affects the sintering quality of the first wax mold layer. A suitable platform temperature helps the wax powder to bond better with the platform under laser irradiation and improves the firmness of the first layer, so that it can provide a stable foundation for the construction of subsequent layers. Different wax materials have different optimal initial platform temperatures, which need to be set accurately according to the properties of the wax powder used to ensure a good sintering of the first layer and to prevent separation of the first layer from the platform or incomplete sintering.

temperature stability

• Printing Process Impact: The temperature stability of the build platform is crucial during the whole wax mold printing process. Large fluctuations in temperature can lead to changes in the physical properties of the wax powder (e.g. fluidity, sintering characteristics, etc.), which in turn affects the bonding effect between the layers of the wax mold and the structural stability of the overall wax mold. For example, a sudden increase in temperature may cause excessive melting of the wax powder being sintered, destroying the structure of the existing wax mold; a decrease in temperature may cause insufficient sintering of the subsequent wax powder, resulting in quality problems such as delamination and cracking. Therefore, printers are usually equipped with a high precision temperature control system that monitors and regulates the platform temperature in real time to keep it within a set stable range, ensuring high quality sintering from the first to the last layer of the wax mold.
• Requirements for different wax mold typesThe requirements for temperature stability of the platform vary for different types and sizes of wax molds. For large, thick-walled wax molds, due to the longer printing time, the cumulative effect of temperature changes is greater, and stricter temperature control is needed to ensure uniform sintering of the internal and external wax structure; while small, thin-walled wax molds, although the printing time is relatively shorter, due to the fragility of their structure, they are more sensitive to temperature fluctuations, and they also need a stable platform temperature environment to ensure the quality of wax molds to avoid deformation, damage, etc. caused by temperature changes. The temperature environment should be stabilized to ensure the quality and to avoid the deformation and damage of the wax molds due to temperature change.

In summary, the key technical parameters of laser power and wavelength, print layer thickness and accuracy, and temperature control of the build platform interact with each other to determine the print performance and mold quality of SLS wax 3D printers, and require in-depth understanding and consideration when using and evaluating these printers.

Frequently Asked Questions:

What is the principle of sand 3D printing?

The principle of sand 3D printing is a manufacturing method that transforms a three-dimensional digital model into a solid sand pattern. Specifically, it utilizes 3D printing equipment to build up layers of sand powder, which are bonded together with a specific binder or curing agent to form a sand mold with a complex internal structure. The sand mold is then dried or cured to make it strong enough to handle the subsequent casting process.

The advantage of this technology is that it meets the need for fast, customized and small production runs, bringing greater efficiency and quality to the casting process.

With the changes in the market, development, many companies will consider buying wax mold 3D printer for printing wax molds (for metal casting and other industries), but for many companies who have not been exposed to 3D hit the equipment may not know much about this aspect, this is the purpose of this article, so that the intention to buy equipment for the enterprise to have an overall understanding of avoiding unnecessary trouble.

I. Define your own needs

Before embarking on a purchase, be sure to clearly sort out your usage needs. For example, determine which field you will mainly use it in, whether it is jewelry making, industrial parts manufacturing or medical model production, etc. Different fields have different requirements on the accuracy, size and material properties of wax models. At the same time, to estimate the approximate amount of printing, is occasionally a small amount of printing for prototyping, or the need for batch, large-scale production, which will affect the printer printing speed, build size and other aspects of the choice, in order to circle the printer type and the general parameters of the range of needs, to avoid blind selection.

Second, understand the printer performance parameters

1. Printing Accuracy: Focus on the minimum layer thickness and the overall dimensional accuracy of the equipment. For example, the production of fine jewelry wax models may require printers with small layer thicknesses (tens of microns) to ensure that textures and other details are clearly presented; while for some industrial functional wax models, the dimensional accuracy needs to be strictly in line with the design requirements to prevent subsequent casting and other processes from having fitment problems.
2. Printing speed: Examine the volume of molding per unit of time and the performance of print speeds for models of varying complexity. If there are mass production tasks, faster printing speed can improve efficiency and shorten the production cycle, but also note that some printers may plummet in speed when handling complex models, which needs to be weighed in the balance.
3. Build Size: Define the maximum size of wax model that can be printed by the printer, and choose it in relation to the size of wax models that are often made in actual business. At the same time, understand the utilization efficiency of the effective printing area to avoid the situation that the nominal size is large but the actual available space is limited, which affects the printing of special shape wax models.
4. Wax Powder Material Compatibility: Check the supported wax powders to make sure that they are suitable for the material you plan to use, especially those with special performance requirements (e.g. high temperature resistance, high strength, etc.). In addition, the convenience of the material changeover is also important for the efficiency of the subsequent use. If the material has to be changed frequently, a cumbersome changeover process will waste a lot of time.

III. How to avoid common buying traps

1. Be wary of over-promotion: Some manufacturers may exaggerate the performance parameters of their printers, such as claiming ultra-high precision that is difficult to achieve in actual use, or boasting extremely fast print speeds without stating that it is under a specific simple model. To carefully check the actual technical specifications in the product manual, and as far as possible to request a live demonstration or view the actual print samples to verify the authenticity of the promotional content.
2. Avoid the temptation of low pricesWax 3D printers that are priced too low often have shortcomings in terms of quality, performance or after-sales service. Do not simply be attracted by the low price, but comprehensively compare the configuration, functions, reputation, etc. of products at different price points to analyze their cost-effectiveness and prevent buying equipment that seems cheap but has frequent problems in subsequent use and high maintenance costs.
3. Look for hidden clauses: When signing the purchase contract and other documents, read the terms and conditions carefully and pay attention to whether there are any hidden fee clauses (e.g. charges for software upgrades at a later stage, high-priced charges for the replacement of certain key accessories, etc.) or ambiguous expressions of key after-sale contents such as the scope of the warranty of the equipment and the time, so as to avoid any unnecessary disputes and additional expenses in the subsequent period.

IV. Ensuring the quality of after-sales service

1. Technical support responsivenessUnderstand the technical support channels provided by the manufacturer, such as whether there is a 24-hour customer service hotline, online technical support platform, etc., and ask about its average response time. When problems are encountered in the process of use, it is crucial to get professional technical guidance to solve the problems and resume production in a timely manner.
2. Repair service and spare parts supply: Examine the manufacturer's maintenance service network coverage, can arrange timely maintenance personnel to repair (especially for large, heavy industrial-grade printers this is very critical). At the same time, to confirm whether the supply of original spare parts is sufficient, timely, to avoid equipment failure due to waiting for parts and long downtime, in addition, to understand in advance the approximate costing of maintenance costs, to ensure that the cost of maintenance in the later acceptable range.
3. Training services: For first-time users, good training services can help operators quickly familiarize themselves with the operation and maintenance of the equipment. Ask the manufacturer whether to provide free operation training, training content is comprehensive (covering the use of software, routine maintenance, simple troubleshooting, etc.), to ensure that the equipment can be put into use smoothly after arrival.

V. Importance of user evaluation

1. Multi-channel collectionThe user reviews of related products can be searched through the Internet, such as professional 3D printing forums, e-commerce platform buyer reviews, industry exchange groups, etc. Different channels can obtain more comprehensive and objective feedback. Different channels can obtain more comprehensive and objective feedback, from the printing effect, stability to after-sales service and other aspects, to understand the real experience of other actual users in the process of use. Of course, every product is not perfect, from the many brands to choose a better is our purpose.
2. Focus on content: Focus on the frequency of equipment failure, printing accuracy is stable, after-sales service to solve the problem of the actual effect and other key elements of the evaluation. For example, if more than one user feedback on a printer often appear a variety of faults and can not be used, it is necessary to carefully consider the purchase of this product; if the general praise of the manufacturer's after-sales maintenance in a timely manner, a good attitude, then the after-sales aspects of the relative more secure.
3. Compare different brands and models: Compare and analyze the collected user reviews of different brands and models of 3D printers to find out the products with better reputation and high comprehensive satisfaction in all aspects, which will help narrow down the choices and make more appropriate purchase decisions. If necessary, you can personally visit the supplier in the factory, after all, large wax model 3D printer are not cheap, personal communication can learn a lot of useful information. Face-to-face communication is important, and for really strong brands they are happy for you to visit them in person.

In conclusion, when buying a wax 3D printer for the first time, it is important to do your homework, consider all factors, and make a careful choice in order to get a device that meets your needs and saves you money in subsequent use.

This paper centers on the SLS wax 3D printer, describes in detail its working principle, analyzes the advantages over traditional processes, introduces the wide range of applications in aerospace, automotive manufacturing, art creation, ships and other fields, and looks forward to its future development prospects, aiming to give readers a comprehensive understanding of the important role played by this advanced printing technology in many aspects of modern manufacturing.

The working principle of SLS wax mold 3D printers

The SLS Wax Mold 3D Printer operates on a highly innovative principle. It starts by spreading a specially formulated wax powder material evenly over the printing platform, forming a thin layer of powder. Subsequently, a high-energy laser beam selectively scans and sinter the wax powder in accordance with the predefined 3D model data. Under the high temperature of the laser beam, the scanned wax particles instantly melt and bond to each other, and when cooled down, they solidify to form a layer of wax mold structure with a specific shape. Next, the printing platform is lowered a certain distance, a new layer of wax powder is laid down, the laser continues scanning and sintering, and so on, layer by layer, to finally build a complete wax mold. This layer-by-layer manufacturing method is capable of accurately reproducing complex three-dimensional geometries, and even models with fine internal holes, thin walls, or complex curved surfaces can be excellently printed.

Advantages of SLS Wax Mold 3D Printer

(i) High degree of design freedom

The traditional wax modeling process is often limited by molds and other factors, which makes it difficult to realize some very creative and complex designs. The SLS wax 3D printer completely breaks this constraint, allowing designers to use their imagination to create a variety of unprecedented shapes. Whether it's a piece of jewelry with a delicate internal structure or an industrial component with a unique aerodynamic shape, if it can be designed with modeling software, the SLS Wax Mold 3D Printer can bring it to life, providing unlimited possibilities for product innovation.

(ii) Excellent material properties

The wax powder material used is specially formulated to provide good strength and stability after sintering, while retaining the properties of the wax material itself that make it easy to subsequently process. For example, in the casting process, these wax molds are able to carry out the subsequent processes such as dewaxing smoothly, and can ensure that under the high temperature casting environment, there will be no deformation, cracking and other problems affecting the quality of the final casting, which lays a solid foundation for the production of high-quality metal castings.

(iii) Efficient productivity

Compared to the traditional manual or partially machined production of wax models, the SLS 3D wax model printer is capable of automated and continuous production. Once the model data has been imported, the printer is able to complete the entire wax model printing process autonomously according to the settings. It is also possible to lay out several different small wax models for mass production on a single printing platform at the same time, which greatly reduces the production cycle time, and is especially suitable for time-critical orders or mass production tasks.

The main application areas of SLS wax mold 3D printers

• AerospaceSLS wax mold 3D printing can produce wax molds of complex structures such as aero-engine blades, impellers, etc. These wax molds, through the subsequent investment casting process, can produce high-performance metal parts for use in aircraft engines, fuselage structural parts, etc., which can help to reduce the weight of the aircraft, improve fuel efficiency, and enhance the performance of the flight.
• Automotive ManufacturingSLS wax mold 3D printing is widely used in the R&D and production of automotive parts. For example, automotive engine block, cylinder head, intake pipe, gearbox shell and other complex parts of the wax mold production, through the rapid printing of wax mold and casting, can shorten the new product development cycle and reduce costs, accelerate the speed of automotive product replacement. In addition, it can also be used to manufacture automotive interior parts, personalized customized parts and jigs and fixtures, etc., to improve production efficiency and product quality.
• Ship Pumps and ValvesThe use of SLS wax mold 3D printing technology can greatly save materials for some rare and precious metal parts in ship pump and valve equipment. The whole printing molding to avoid welding connection, can realize small batch rapid core making, save the time of mold opening, simplify the structural design, improve structural performance, reduce costs.
• Energy power areaIn the energy and power industry, SLS 3D printing can be used to create wax molds to produce high-quality castings for large and complex parts, such as blades and hubs for wind turbines. In addition, for the research and development and trial production of new energy power equipment, the technology can quickly produce wax molds of the required components, speeding up the research and development process, improving the efficiency of energy conversion and saving costs.
• Industrial MachinerySLS 3D printing is commonly used to make wax models of complex parts in various industrial machinery and equipment, such as hydraulic components, transmission gears, molds, etc. of engineering machinery. These parts often have complex internal structure and high precision requirements, SLS wax mold 3D printing can meet their production needs, improve production efficiency and product quality, reduce production costs.
• Art Sculpture FieldArtists and sculptors can use SLS wax 3D printing technology to quickly transform digital models into solid wax models that can be used to create beautiful sculptures. The technology enables the rendering of complex shapes and fine textures, providing greater artistic freedom and possibilities, while shortening the creation cycle and increasing the productivity of the work.

Fourth, what are the factors to consider when buying an SLS wax model 3D printer?

When planning the purchase of an SLS wax model 3D printer, you need to make thorough considerations in order to purchase a device that meets your actual needs, and here are some of the factors to focus on:

• (i) Printing accuracy
  Layer thickness setting: The smallest layer thickness that the printer can achieve determines the fineness of the final wax model. A smaller layer thickness can create models with richer details and smoother surfaces. For example, when making wax models of jewelry with fine textures in the jewelry industry, you need the ability to print with high precision and small layer thicknesses, so you should pay attention to the minimum layer thickness indicator that can be achieved by the equipment. Generally speaking, the layer thickness varies between tens of microns and hundreds of microns, so you should choose the right one according to your specific needs.
  Dimensional accuracyThe overall dimensional accuracy of the wax model depends on whether the printed wax model matches the designed model to a high degree or not, as large deviations may lead to problems in the subsequent casting process. Check the nominal dimensional accuracy of the equipment and the actual user feedback on the model dimensional errors to ensure that it meets the requirements of your industry for the dimensional accuracy of wax molds, which are often very high in precision casting.
• (ii) Printing speed
  Molding volume per unit time: Knowing the volume of wax molds a printer can print per hour or per day has a significant impact on productivity. If there is a mass production task, e.g. in the case of mass production of jewelry molds or industrial parts, a higher volume per time means faster order fulfillment, shorter production cycles and lower time costs.
  Speed performance under different model complexity: Some printers print simple structural models at a reasonable speed, but when it comes to complex models with fine internal structures the speed drops drastically. It is necessary to examine the stability of its speed when dealing with models of various complexity, to ensure that in actual production, both simple and complex wax models can be printed at a more reasonable speed.
• (iii) Build size
  Maximum print size: Consider the maximum size of the wax model that the printer can accommodate, taking into account the size of the wax models that you regularly make and the possible future expansion of your business. For example, if you mainly produce small dental molds, you may not have high requirements for large size, but if you are involved in the production of large sculpture molds or wax molds of larger industrial parts, you will need a larger build size, or else you can only print in pieces and then splice them together (which is often encountered in the actual production) and other complex ways to complete the process, thus increasing the process difficulty and cost.
  Effective print area utilization efficiency: Some printers have a large nominal maximum print size, but due to the internal structure and other reasons, the actual flexibility to use the effective print area is limited, which will also affect some special shapes or layouts of the wax mold printing, to carefully understand this aspect of the situation, to ensure that it can make full use of its print space.
• (iv) Wax powder material compatibility
  Supported Wax Powder TypesDifferent wax powder materials have different characteristics, such as melting point, hardness, fluidity, etc., which are suitable for different application scenarios. Make sure the printer can be compatible with the wax powder you plan to use, or the mainstream, high-quality wax powder on the market, like some special industries may need high temperature resistance, high toughness wax powder, the printer should be able to adapt well.
  Material replacement convenienceIf there is a need to change different kinds of wax powder frequently for diversified wax modeling, it is important to know whether the material changing operation is easy and fast, complicated changing process will waste time and reduce the production efficiency, so we should examine whether the design of the material changing system is humanized.
• (v) Equipment stability and reliability
  failure frequency: By checking user reviews, consulting other users who have used the equipment, etc., to understand the frequency of malfunctions in the normal course of use, a printer that frequently breaks down will seriously affect the production schedule, resulting in increased maintenance costs and delays in delivery and other issues.
  Component Durability: The durability of key components inside the printer, such as the laser generator unit and the powder spreading system, is critical. High-quality, durable components ensure stable operation of the device for a long period of time, and reduce the downtime and additional costs associated with replacing parts, so it is important to understand the design life of each component and how it performs in actual use.
• (vi) Software packages
  Slicing Software FeaturesSlicing software is responsible for processing 3D model data into commands that can be recognized and executed by the printer, and it is important that it is powerful. For example, whether it can automatically generate a reasonable support structure (critical for some wax models with overhanging parts), whether it can make fine adjustments to the printing parameters, whether it supports the import of multiple model file formats, etc. A good slicing software can optimize the printing effect and improve the success rate.
  Ease of operation of the softwareThe easy-to-understand software reduces operator learning costs, reduces printing failures due to operational errors, and makes it easy for people of all skill levels to quickly get started with the printer for wax modeling.
• (vii) After-sales service
  Technical support responsiveness: When problems are encountered in the process of use, it is critical to get timely technical support from the manufacturer, and a quick response can solve the problem as soon as possible and resume production. Understand the technical support channels provided by the manufacturer (such as telephone, network customer service, etc.) and the average response time and so on.
  Repair service and spare parts supply: When the equipment fails and needs to be repaired, can the manufacturer arrange for maintenance personnel to visit in a timely manner, and whether there is an adequate supply of original spare parts, to avoid waiting for spare parts and a long time downtime, but also to understand the approximate situation of the maintenance costs, to ensure that the cost of maintenance in the latter part of the acceptable range.
• (viii) Prices and costs
  Purchase price of equipmentThe price difference between different brands and models of SLS wax model 3D printers may be large, and it is necessary to do market research and comparison.
  Long-term operating costs: In addition to the purchase price, but also consider the subsequent use of the process of consumables (wax powder) costs, equipment maintenance costs (repairs, parts replacement, etc.), electricity and other long-term operating costs, a seemingly inexpensive purchase price but consumables and maintenance costs of the high cost of printers, in the long run may not be an affordable choice.

Taking all these factors into consideration, you will be able to choose an SLS wax model 3D printer that meets your needs, is cost-effective, and operates stably and reliably, thus laying a good foundation for wax modeling and the subsequent smooth development of related production operations.

V. Prospects for the development of SLS wax mold 3D printers

3D printing sand casting is an innovative casting method that integrates 3D printing technology and traditional sand casting process. This paper describes its principle, advantages, process and application areas, focusing on its outstanding performance in design freedom, production cycle, accuracy and quality, cost-effectiveness and green environmental protection. This advanced casting technology has revolutionized the manufacture of complex parts for many industries and is of great significance in modern industrial production.

principle

3D printed sand casting is based on a digital three-dimensional model. First of all, the 3D printing equipment is used to print out the sand mold (including upper and lower sand molds, cores, etc.) by stacking special sand materials (usually resin sand containing binder, etc.) layer by layer in accordance with the cross-section information of the model. Then, liquid metal is cast into the cavity formed by the sand mold, and after the liquid metal cools and solidifies, the sand mold is removed to obtain the desired metal casting.

workflows

1. 3D modelingThe casting model is designed using professional 3D modeling software (e.g. SolidWorks, UG, etc.), and at the same time, the casting process requirements, such as parting surfaces, draft slopes, machining allowances, etc., need to be taken into account, and then the model is converted into a file format suitable for 3D printing (e.g. STL format).
2. Sand Printing: The printing materials (sand and binder) are loaded into the silo of the 3D printing equipment, and under the control of the computer, the nozzle selectively sprays the binder onto the sand layer in accordance with the cross-section data of the model, so that the sand grains are bonded together and build up layer by layer to form the sand pattern. After the printing is completed, the sand model is subjected to appropriate post-processing, such as removing excess sand particles and reinforcing weak parts.
3. Preparation for casting: The printed sand molds are assembled and placed in the casting equipment to prepare the metal liquid for casting. At the same time, the raw metal is melted and treated to achieve the proper casting temperature and composition requirements.
4. Casting and cooling: Slowly pour the treated liquid metal into the cavity of the sand mold to ensure that the liquid metal fully fills the cavity. After casting, wait for the liquid metal to cool and solidify naturally.
5. Sand Cleaning and Post-treatment: After the castings are cooled, the sand mold is removed by vibration, sandblasting, cutting, etc. to obtain the castings. Then the castings are cleaned, polished, heat-treated, machined and other post-treatment processes to meet the final product quality requirements.
