China3D printingNet January 18, Florida-based Sintavia has expanded its metal3D printingAbility to improve its3D printingThe ability of rocket parts.The printer it bought is not ordinary metal3D printingSystem, but the M4K-4 machine of German AMCM. 3D printingThe machine is a modified version of the EOS M400-4 system, which is more than twice the height of the original EOS machine. Sintavia has purchased two other M4K-4 systems for3D printingRocket parts.The company claims to be “the largest rocket in North America3D printingMachine one” has made considerable progress in the past few years. In addition to the3D printingIn addition to the method and opening of new additive manufacturing facilities, Sintavia also acquired QC Laboratories to expand3D printingTesting of parts. In 2018, it became the first company to obtain Honeywell Aerospace3D printingThe company that approved the part.
Sintavia is the only laser additive manufacturing company in the world approved by Nadcap (image courtesy of Business Wire). All of this is partly due to the investment of Sumitomo Corporation of Japan. Sintavia injected capital. AMCM is a subsidiary of EOS, which develops customized systems when the standard system is not suitable for its application3D printingmachine. The industry-proven M400 has a build volume of 450 mm x 450 mm x 450 mm, while the M4K series has a build volume of 450 mm x 450 mm x 1000 mm, which is one meter in height. Both M400 and M4K provide a single 1kW laser (M400-1 / M4K-1) or four 1kW laser (M400-4 / M4K-4) versions. AMCM team can customize3D printingOther modifications made by the machine include changing the laser wavelength (for example, for the use of copper3D printingBlue or green), adaptability to high temperature materials and variable spot size.

Heavy laser printing.” Sintavia CEO Brian Neff said, “We now have eight M400-4 four-channel laser printers. We hope that the successful strategy adopted by M400-4 can also work on these new M4K-4 units. We are very pleased that we will be the first rocket printer in North America to provide M4K-4 extended layouts to commercial space customers.” The design of M4K-4 is partly due to the desire to use3D printingThrust chamber components are required by commercial space launch companies. The system can produce the entire assembly as a whole, including optimized regenerative cooling channels. This in turn saves time and costs associated with manufacturing components. Sintavia will receive the new machines in June and July 2021 and use them to produce parts made of copper and nickel alloys. Sintavia is not the only company that uses the M4K system to produce rocket parts.Launcher, a Brooklyn start-up company, relies on this technology to produce what it considers to be the largest in the world in a single piece.3D printingLiquid rocket engine combustion chamber. In the new aerospace industry, there is a lot of room for start-ups in various industries. Now, we see that due to the increasingly advanced additive manufacturing technology, the industry is developing very rapidly.
