• 3D Printer

In recent years, "metal 3D printers" have been gaining attention in the metal processing and manufacturing industries. Although the technology is said to still be in development, improvements are being made, and adoption is progressing, particularly in Europe and the United States. With the increase in cost-effectiveness, companies that had previously hesitated to adopt this technology may now find it easier to get involved. In this document, we will introduce an overview of metal 3D printers, their manufacturing methods, and their advantages and disadvantages. If you are considering the introduction of a metal 3D printer, please take a moment to read this. [Contents] ■ Metal 3D printers that can create shapes that could not be made before ■ Representative manufacturing methods ■ Advantages and disadvantages ■ Examples of items that can be made with metal 3D printers *For more details, please refer to the PDF document or feel free to contact us.

• Other machine tools

The awareness of metal 3D printers is steadily increasing year by year, but it cannot be said that many companies in Japan are actually able to utilize metal 3D printers. As a general observation, while Japanese companies tend to consider the use of metal 3D printers as an extension of existing manufacturing methods, in Europe, the United States, and China, there is a mindset of designing and creating things that cannot be achieved with traditional methods through metal 3D printing (additive manufacturing). When comparing to traditional methods, the disadvantages of metal 3D printers are generally cited as follows: ■ Dimensional accuracy comparable to machining is not achievable (precision casting level) ■ Surface roughness is around Ra10 to 25 ■ (Depending on the size of the product) not suitable for mass production ■ Cost **Compared to our company that owns powder bed fusion (PBF) metal 3D printers. Instead of focusing on these disadvantages, it is important to concentrate on the advantages that can be enjoyed specifically because of metal 3D printers and to consider product development through new design (DfAM). We hope to assist you in this regard, so please feel free to consult with us first.

• 3D Printer

It is true that metal 3D printers have the disadvantage of not being suitable for mass production, but they can handle mass production if the items are small. For example, if there are 100 types of aluminum caps, it would require preparing 100 different molds, but with a metal 3D printer, all 100 types of aluminum caps can be created in a single print (there is no need to print 100 times). In this way, metal 3D printers have the advantage of being suitable for mass customization. Fields where mass customization made possible by metal 3D printers can be adopted include the medical field, with implants and dentures being representative examples, and in the industrial field, there is potential for use in low-volume, high-variety production. Our company can create high biocompatibility materials such as titanium alloys (Ti-6Al-4V), pure titanium, cobalt-chromium, as well as materials like stainless steel (SUS), Inconel, and copper using metal 3D printers. Please feel free to contact us, even if it is just for prototyping.

• 3D Printer

With metal 3D printers, it is possible to create complex shapes (such as lattice structures) that were impossible to manufacture using traditional methods, achieve greater weight reduction through topology optimization, and eliminate the need for welding or brazing due to the unique capabilities of additive manufacturing. The benefits are numerous. So, what are the cases where the use of metal 3D printers may not be suitable (potential disadvantages)? - When creating items that can be made using traditional methods such as casting, forging, or machining, the cost may be relatively high when using metal 3D printers. - If a high level of precision or surface roughness is required, additional post-processing may be necessary. - (Depending on the size of the printed object) it is not suitable for mass production. The important thing is not to focus on the disadvantages of metal 3D printers (or to think of them as a replacement for traditional methods), but to engage in product design and development that leverages the unique advantages of metal 3D printing. Our company formed a technical partnership with Tokyo R&D last autumn, establishing a system that not only provides 3D printing but also offers design advice. Please feel free to contact us regarding prototypes, delivery times, estimates, or any questions you may have.

• Prototype Services

Our company manufactures PREP powder for metal 3D printers. PREP powder for metal 3D printers is produced using the Plasma Rotating Electrode Process (PREP) and is characterized by "high sphericity," "absence of satellites," and "no gas defects within the powder." Objects created with PREP powder demonstrate high fatigue strength even without HIP treatment or heat treatment, confirming a reduction in build time and costs compared to conventional powders. Currently, the use of simulations in metal 3D printing is advancing, but simulations assume a 100% sphericity for the material powder. Conventional atomized powders have lower sphericity, leading to discrepancies between simulation results and actual build outcomes. However, with PREP powder, which has nearly 100% sphericity, this concern is eliminated. For specific data, please refer to the downloadable materials.

• Other metal materials

Our company is capable of 3D printing pure copper using metal 3D printers. Pure copper is widely used for conductive and heat exchange components due to its excellent thermal and electrical conductivity, and shapes with internal flow paths are required. Copper is considered a difficult material to apply in metal 3D printing because its high thermal conductivity causes heat from the beam to dissipate instantly. However, at JAMPT, we have successfully improved the printing parameters using our long-standing experience since the Koiwai era and achieved layered printing of copper with an electron beam metal 3D printer. Additionally, our company offers various heat sink designs in pure copper.

• 3D Printer

Our company offers contract manufacturing using metal 3D printers (Additive Manufacturing). The 3D printing technology creates slice data based on the 3D CAD data of the target product or part, and builds the object layer by layer. A layer of metal powder (approximately 30 to 100 μm) is spread, and by irradiating a beam (electron beam/laser beam) according to the slice data, the metal powder is melted and solidified. This process is repeated while lowering the build stage by one layer to complete the object. 【Features】 ■ Manufacturing of complex shapes and optimized parts ■ Improved material yield and reduced processing costs ■ Reduction of unnecessary intermediate inventory *For more details, please refer to the PDF document or feel free to contact us.

• 3D Printer

Our company offers contract manufacturing services using metal 3D printers. In metal 3D printers that use metal powder, there are two types of heat sources for melting the powder: "electron beam" and "laser beam." The "electron beam" has a higher output compared to the "laser beam," resulting in faster manufacturing speeds. In the "electron beam" method, a pre-sintered state is created to prevent the charging of metal powder, and since it is manufactured at high temperatures, there is less residual stress after manufacturing. This also reduces distortion and cracking due to internal stress, and less support material is required. In the "laser beam" method, smaller powder particle sizes are used, which results in slower manufacturing speeds, but it excels in surface roughness of the manufactured products and is suitable for creating relatively fine structures. 【Features】 ■ Electron Beam Method - Fast manufacturing speed - Requires less support material, providing excellent cost competitiveness - Almost no residual stress occurs after manufacturing, suppressing distortion and cracking due to internal stress ■ Laser Beam Method - Uses powder with small particle sizes - Extremely excellent surface roughness of the products, suitable for creating fine structures *For more details, please refer to the PDF document or feel free to contact us.

At JAMPT, we are working on utilizing a new aluminum alloy powder for metal 3D printers in new applications through additive manufacturing, based on a patent implementation agreement. The JIS AC8A alloy is well-known as a heat-resistant aluminum alloy for casting. However, when this alloy is formed using a metal 3D printer, it does not achieve the high-temperature strength that is conventionally known. To improve this, it has been confirmed that using an alloy with added transition metals shows values 1.5 to 2.0 times higher than conventional ones. In the manufacturing process, a laser-based metal 3D printer is used, and there is no need to perform the conventional T6 treatment (510°C solution treatment ⇒ water quenching ⇒ aging). 【Chemical Composition (%)】 ■Si: 10 ■Cu: 1 ■Mg: 1 ■Ni: 1 ■Fe: 2 ■Al: bal. *For more details, please refer to the PDF document or feel free to contact us.
