Metallic Additive Manufacturing Capabilities
- Small Direct Metal Laser Sintering System (EOS M100) that uses a 200 W Yb (Ytterbium) fiber laser with wavelength 900 – 1200 nm, 40 µm diameter of the laser beam in the building area, and 163 mm focal length of the F-Theta lens (flat plane optic). It operates a dual re-circulating filter system with F9 (pre-filter) and F13 (main filter). The minimum exposure diameter area is 100 mm with an exposure speed up to 7000 mm/s and the scanner position repeatability is < 22 μ rad. The machine can operate under Argon or Nitrogen inert gases and includes all the required software and validated process parameters for printing of bulk Steel 316L and Ti-6Al-4V metal
- Medium Direct Metal Laser Sintering System (EOS M290) that uses a 400 Watt Yb (Ytterbium) fiber laser with a wavelength of 1060-1100 nm and using an F-Theta focusing lens; the focal length of the F-Theta lens is 410 mm. The machine also contains self-cleaning filters. The minimum exposure area is 250 mm x 250 mm with an exposure speed up to 7000 mm/s and a scanner position repeatability of < 11 μ rad. The z-axis repeatability of positioning is ≤ ± 0.005 mm. EOS M290 uses am high-speed steel and ceramic blades with travel speed 40-500 mm/s. In addition, the integrated platform has a heating module capable of operating between approx. 40 to 200° C. The EOS M290 machine license includes a full academic license with validated parameters for bulk MS, MP, Ti-6Al-4V, AlSi10Mg, IN625, IN718, HX and 316L.
- The Metal Additive Manufacturing Laboratory at the University of Memphis also houses a Formlabs Form 2 SLA printer and a Markforge Onyx Series Printer.
