- 2. The Metal Laser Sintering Process
- 3. Key Features • Robust system design & construction • Patented powder layering system • Imaging system & software • Integrated “hands off” powder handling • Global Support and Service including backup manufacturing
- 4. Robust Design & Construction • Designed for the manufacturing floor • Emphasis on precision, repeatability and reliability • Completely manufactured in Riom, France
- 5. Patented Roller- Wiper layering System Metal wiper lays the powder bed on the build plate and a special roller compacts the metal powder to the desired layer thickness/ density on return. Parts from one batch to the next are sintered with consistency and quality Easier to handle size inconsistency in the metal powder and still achieve better results Helps to work with smaller metal powder grain size ( down to 3 micron) when extreme detail is needed Works successfully with spherical and non-spherical powder particles Works with Metal and ceramics in the same equipment

- 10. Standard built-in Chuck Standard built-in Chuck under the build plates gives you true Z build height from the top of the plates rather than making you lose 98 mm when chuck mounted on the top of the build plate. Quick automatic and semi-automatic change of build plates Allows you to move the build plate to the other equipment for post processing (when needed) without loosing the references.
