The portfolio of 3D printing manufacturer 3D MicroPrint GmbH includes the DMP60 series (consisting of the DMP60, DMP63 and DMP64) as well as the DMP70 series. These series of 3D printers are intended for industrial manufacturing on a microscale. Just like the DMP60 series, the DMP70 series also uses Micro Laser Sintering technology. You can think of this as a mix of additive manufacturing and micro machining; this is a method where metal parts are produced with a very high precision in microns. An extremely small laser beam, special metal powder as well as extremely thin layers are used in this process.
It is important to note that this series of 3D printers consists of two machines, unlike the DMP60 series, which consists of three. In this case, there are the DMP73 and the DMP74, which differ in their diameter of the laser dot. For the 73 version, this is ≤ 30 µm; for the 74 machine, this value is ≤ 20 µm.
More Features of the DMP70 Series Printers
If you are interested in micro 3D printing with metals, you should also be aware of the advantages of the DMP70 series over the DMP60: this new series requires less space, has less weight, and incurs less cost. Especially if you want to print with precious metals, you will benefit from an optimized machine design with the DMP70 series 3D printers, resulting in less material waste, and the CE and UL certifications as well as pneumatic shock absorbers for harsh environments. The manufacturer states that the DMP70 series is particularly suitable for batch production. As for the material, in this case you can use reactive as well as non-reactive materials. This includes, for example, stainless steel, molybdenum, tungsten, titanium or even gold.
