The first Nature article in the field of 3D printing technology in 2024 was published on February 27th. A team of researchers from the Institute of Metals, Chinese Academy of Sciences (IMS) published an article titled "High fatigue resistance in a titanium alloy via near void-free 3D printing".

The article argues that the underlying 3D printed microstructures have a naturally high fatigue resistance, and that the degradation of this property may be caused by the presence of micropores. Conventional efforts to eliminate micropores often result in tissue coarsening, while the process of tissue re-refinement brings about the recurrence of porosity and even triggers new disadvantages such as the enrichment of α-phase at grain boundaries, making the microstructures dilemma of in-and-out efforts.
During the heat treatment research conducted by the CAS team, a key post-treatment process window was discovered, where the phase transition and grain growth of 3D printed titanium alloys at high temperatures are asynchronous. With sufficient superheat, the α to β phase transition occurs immediately, and although the β phase growth temperature has been reached, the grain boundaries need a gestation period to rearrange themselves. Taking advantage of this valuable heat treatment window, the researchers determined a heat treatment method combining hot isostatic pressing and high-temperature short-time treatment, which both achieved tissue refinement and prevented α-phase enrichment as well as the reappearance of micropores, and ultimately prepared near-printed state 3D printed titanium alloys that are almost free of micropores.

TC4 titanium alloys with this microstructure achieve a high fatigue limit of about 1 GPa, exceeding the fatigue resistance of all current additively manufactured and wrought titanium alloys, as well as other metallic materials.

The 2nd Nature article in the field of 3D printing technology in 2024 was published on March 13th. Building on a continuous liquid interface production technique developed at the university in 2015, researchers at Stanford University have developed a 3D printing technique for more efficient production of microscale particles, making up to 1 million micron-sized particles per day with high precision and customizability.

Nano- to micron-scale particles have a wide range of applications in biomedical devices, drug and vaccine delivery, microfluidics, and energy storage systems. However, conventional fabrication methods require balancing multiple factors such as fabrication speed and scalability with particle shape and uniformity and particle properties.
Researchers at Stanford University have developed a scalable, high-resolution r2r CLIP 3D printing process that uses single-digit micrometer resolution optics with continuous film to enable rapid, variable fabrication and harvesting of particles with a variety of materials and complex geometries. With this technology, researchers can achieve micron-level precision 3D printing while maintaining high production speeds and flexibility in material selection, opening up new possibilities for particle manufacturing.

This scalable particle production technology has been demonstrated toManufacturing potential in a wide range of fields from ceramics to hydrogel manifoldsThe research was published under the title "Roll-to-roll, high-resolution 3D printing of shape-specific particles," and subsequently has potential applications in microtooling, electronics and drug delivery. The study was published under the title "Roll-to-roll, high-resolution 3D printing of shape-specific particles".

On April 4, 3D Printing Technology Reference noted that a traditional metal injection molding developer called Greene Group Industries (GGI) acquired Holo, a developer of indirect metal 3D printing technology, in an event that is actually of significant landmark significance.One is that "advanced" 3D printing technology has failed to find enough industry applications to support its healthy growth, and the other is that traditional manufacturing industries have recognized the value of 3D printing technology to their production processes.The

Holo isAutodeska spin-off company of the company that developed the light-curing-based PureForm metal indirect 3D printing technology that enablesPure copper, stainless steel, titanium alloy, nickel-based high-temperature alloyRapid prototyping and scale-up production of complex metal parts in materials such as...In particular, it should be noted that the company was the first to tackle pure copper 3D printing based on DLP technology.Through DLP + DegreasingSintering processThe densities of the formed pure copper average 96-98%, which is sufficient to achieve the thermal and electrical conductivity of 95% for bulk copper. Additionally, the process may reduce the cracking problems associated with laser printing. Based on an already proven process, Holo is focusing on the development and manufacturing of heat sink parts rather than selling 3D printers.3D Printing Technology Reference 2021 reports that one of its pilot production lines20,000 pure copper small parts can be produced per monthand hopes to produce millions of copper heatsink parts each year.

With a 100-year history of providing high-quality metal parts, GGI is recognized as an industry leader in a variety of metal forming technologies, including stamping, forming, CNC machining, wire EDM, and metal injection molding (MIM). Its advanced manufacturing, sales, and support network allows it to quickly provide prototypes and develop short-run production processes from initial product concepts.

Holo's technology complements our metal injection molding, stamping and precision machining offerings," said GGI's CEO. This deal allows GGI to deliver prototype metal parts in less than two weeks with surface quality and feature resolution comparable to metal injection molding.PureForm additive manufacturing technology will strengthen our partnership with our customers by supporting faster iterations throughout the product lifecycle., while GGI maintains its superior engineering services and quality."

Holo's flagship PureForm additive manufacturing technology uses a metallic paste made from a blend of MIM powder and light-curing resins to enableDeveloping Indirect 3D Printing of High-Resolution, High-Throughput Parts. Specifically, the technology produces high-precision part blanks based on the principle of photopolymerization from a mixture of metal powder and photosensitive polymers. A mask exposure allows precise and fast molding of the entire layer, and the polymer binder selectively cross-links locally, bonding the metal powder together. The printed blank is degreased and sintered to form a densified part.

Indirect metal 3D printing.end upIntegration with the MIM industry

The back-end process of indirect 3D printing technology is identical to that of MIM technology, making it very easy for traditional metal injection molding manufacturers to incorporate the technology into their production process.

Indirect 3D printing technology helps enable rapid prototyping that is difficult to achieve with traditional manufacturing methodsThis is the type of technologyOne of the key values for the MIM industryGGI's acquisition of Holo is a key reason why 3D printing technology is an important complementary or even disruptive technology for early part development in the MIM field, as it eliminates the need for molds and dies and significantly improves development flexibility, shortens development time, and reduces development costs.

Currently, indirect metal 3D printing technologies such as binder jetting and light curing use powder for MIM as the 3D printing material, which has not increased the material cost for the MIM industry. For indirect metal 3D printing based on light curing, it is possible to achieveUltra-precision 3D printingBetter surface quality and finer detailed features.surpassing evenMIM-standardized parts. On top of that, Holo claims that its technology enablesScale production of complex designsand is considered ideal for aerospace, automotive, medical, electronics and industrial applications.

Polar Bear 3D Printing
If Apple, Huawei, Samsung, Xiaomi, Glory, OPPO, vivo, these 3C big manufacturers really adopt 3D printing process in large quantities, it is difficult for domestic manufacturers to be able to withstand so many production tasks at present. It may take hundreds or even thousands of metal 3D printers, printing titanium alloy powder up to a thousand tons/year, to meet the delivery of high-volume parts.

Relevant institutions predict that within 2030, the largest application market of 3D printing technology will appear in 3C consumer electronics/automotive and other civilian areas, up to the level of hundreds of billions of dollars, more than the current military defense market, presenting several billions or even tens of billions of dollars of level of the application of the enterprise.

With the iterative upgrading of 3D printing technology and the decline in the cost of raw materials, 3D printing continues to improve efficiency and reduce costs, and the downstream application areas continue to expand. Especially with the domestic and foreign consumer electronics head manufacturers have layout 3D printing technology in smart phones, watches and other 3C products, such as folding screen cell phone shaft cover, electronic watch case, cell phone frame, bezel and other parts using 3D printing technology manufacturing, 3D printing technology in the 3C consumer electronics parts in the mass production of the application (3D3C) is accelerating penetration. According to Statista and Wohlers data statistics, in 2022 the global consumer electronics market size of about 1.01 trillion U.S. dollars (about 7.27 trillion yuan), of which the market size of 3D printing in this field is 2.127 billion U.S. dollars (about 15.306 billion yuan), the penetration rate is only about 0.21%, with great upside. CITIC Securities "Electrical Wisdom Industry 3D Printing Research: Titanium Alloy and 3D Printing from Consumer Electronics" report shows that only titanium alloy 3D printing in the field of consumer electronics market space is expected to exceed 10 billion yuan, 3D printing in the field of consumer electronics has a huge space for development of hundreds of billions of dollars.

In the 12th Shanghai Injection Molding Forum held on March 6, Dr. Zong Guisheng, Chairman of Beijing SANDI Technology Co., Ltd, in a report entitled "SANDI 3D Printing of Metals and Ceramics in the 3C Industry", reviewed the technical research and application progress of 3D printing in the field of 3C electronics, analyzed the problems and bottlenecks faced by 3D printing in the application of 3C, and explored the technology of 3C applications. development direction.
The manufacturing of 3C products requires high surface quality, part flatness, dimensional accuracy, high product demand, automated production and low cost. Based on the above characteristics, at this stage, SLM selective laser melting and BJ binder jetting can be used for the manufacturing of 3C electronic parts and components through two main technology processes. Among them, the SLM process is characterized by high precision, high complexity and high densification, while the BJ process has excellent surface quality and dimensional accuracy, high efficiency and high throughput.

The use of 3D printing technology in smartphones and watches can achieve high strength and lightweight products, while optimizing production time and reducing production costs. For example, a manufacturer using titanium alloy 3D printing of folding screen cell phone hinge shaft cover, the thickness of only 9.9mm, the strength of the enhancement of 50%, while reducing the weight of 62%, the number of hinged parts from 92 reduced to only 4; titanium alloy 3D printed cell phone center frame, weight reduction of 9%.

Why use titanium alloy material? Dr. Zong Guisheng from the titanium alloy of several major characteristics of the analysis: titanium alloy of high specific strength, aluminum alloy 1.3 times, magnesium alloy 1.6 times, stainless steel 3.5 times; titanium alloy of high thermal strength, can be in the 450-500 ° C temperature long-term work; titanium alloy of corrosion resistance is good, acid, alkali, and atmospheric corrosion, pitting corrosion, stress corrosion resistance is particularly strong; titanium alloy of low-temperature Titanium alloy low temperature performance is good, the gap element is very low titanium alloy TA7 in -253 ° C can also maintain a certain degree of plasticity; titanium alloy chemical activity, high temperature can be with hydrogen, oxygen and other gaseous impurities in the chemical reaction, the generation of hardened layer.

Why use 3D printing technology? Dr. Zong Guisheng said, for one thing, the traditional machining of titanium alloy has certain bottlenecks. Because of the high temperature titanium chips easy to burn, poor thermal conductivity, chemical affinity, small modulus of elasticity, cold hardening phenomenon is serious and other problems, resulting in tool wear, workpiece clamping deformation, parts fatigue strength reduction and other problems. Secondly, there are certain problems in the manufacture of titanium/aluminum composite panels. The traditional solid? Solid composite preparation method is susceptible to time, temperature and diffusion coefficient and other factors, resulting in interface metal bonding quality, low material utilization and other issues. Third, 3D printing can realize high integration and reduce assembly. Take the water drop hinge of the folding screen cell phone as an example, the number of parts is as many as 130+, and each part needs to be accurately aligned, which makes it extremely difficult to design. Module assembly technology is complex and involves many patent barriers, so the yield of finished products is low after multiple processes. Fourth, 3D printing to help reduce the cost of titanium alloy manufacturing, releasing a larger market space for 3D printing, and promoting its large-scale application.

As a 3D printing total solution provider focusing on green rapid manufacturing, based on years of laser 3D printing 1.0 equipments and applications, SANDI Technology has independently mastered 3DP, BJ binder jet 3D printing 2.0 equipments, materials and processes, which can meet the manufacturing needs of products of different sizes (from millimeter to meter) and provide users with full-size, multi-material and full-chain rapid manufacturing services. At present, SANDI Technology is exploring the application of 3D printing in 3C electronic field through independent research and development of technology process and industrialization cooperation with supply chain enterprises of famous 3C manufacturers.

For example, the titanium-aluminum alloy laminated composite cell phone frame printed with SANDY SLM can improve the interface strength by 40% compared with the traditional rolling process. customized in-ear hearing aids printed with SANDY SLM have titanium alloy shells up to the ultimate wall thickness of 0.15mm, are lightweight, invisible, 15 times tougher to resist falls, safe and non-allergenic. The product has obtained the national registration certificate for Class II medical devices and realized mass production.

SANDI Technology has completed the development of BJ binder jet metal/ceramic molding equipment such as R&D type R series and production type P series, and dozens of equipments have been installed and used; completed the development of systematic material processes for iron-based materials, non-ferrous metals, high-temperature alloys, refractory metals, ceramic materials, inorganic salts, polymer materials, food materials, etc.; and responded to the multi-species by advancing the CAE simulation and prediction solutions, small batch agile manufacturing needs. In addition, three emperor technology joint Shenzhen Vocational and Technical University to build a joint laboratory of additive manufacturing technology, at the same time, joint Shenzhen Tsinghua University Research Institute, Shanghai Jiaotong University and other research institutes of the relevant team to jointly carry out binder injection molding and other materials, process and application of basic technology research, and to promote the industrialization of the industrial molds, cutting tools, 3C electronic products, and complex, large size and complex ceramic products and other fields of application. Application.

For the application of 3D printing in 3C field, Dr. Zong Guisheng said that the market potential of this application is very large, and the current SLM and BJ technologies have relevant application prospects, but there is still a need to solve a series of problems such as product dimensional accuracy, surface finish and automated mass production. Regarding the direction of technology development for 3C applications, he proposed that automated production can be realized through the development of 3C-specific SLM equipment; in the future, Area Laser 3D Printing (AL3DP) technology, which has great potential for large-scale manufacturing, may become a new quality of productivity for the realization of applications such as 3C and bulky products, which is worth paying attention to and looking forward to.
