Plastic 3D printing
Two build platforms with different sizes:
- 1 platform is 115 x 72 x 230 mm with an xy resolution of 30 µm and
- 1 platform is 84 x 52.5 x 230 mm with an xy resolution of 21.5 µm
- Both platforms have a z-axis resolution of at least 25 µm.
Various types of plastic material can be printed
Examples:
- High temperature resistant material
- Ceramic-filled plastics
- Biocompatible materials
- ABS and rubber-like materials
3D Metal printing
Sisma Mysint 100 PM
- Building volume of 100 x 100 mm high in diameter
- In principle, stainless steel is used for printing, but other materials such as aluminium, titanium and bronze are also possible
- The printer is fitted with a glove box to enable reactive materials such as titanium to be printed.
* Sisma Mysint 100 PM metal printer is currently offline due to renovation. It is expected to be available again around mid-December 2024.
DMG Mori Lasertec 30 SLM (from 2021 on in its last testphase)
- Powder bed with 300 × 300 × 300 mm construction volume
- High precision building of 3D parts with layer thicknesses between 20 and 100 µm for maximum productivity
- Dynamic adjustment of the focus diameter between 70 and 200 µm
- Application-specific fibre laser sources of 600 W
- Optimised shield gas volume flow for highest component quality with minimum Argon consumption < 72 l / hour
- Maximum work safety due to closed material cycle and integrated powder recycling
- Material exchange via replaceable powder module
* DMG Mori Lasertec 30 SLM metal printer is currently offline due to renovation. It is expected to be available again around mid-December 2024.
