SLS-METALS
The Metal Laser Sintering Process
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
Robust Design & Construction
• Designed for the manufacturing floor• Emphasis on precision,
repeatability and reliability• Completely manufactured in
Riom, France
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
Imaging System & Software
• High power, long life fiber lasers• Precise beam positioning• Scan strategies optimize speed
and part quality
AlSi12
Integrated “Hands Off” Powder Handling
• Automated powder handling• Good atmosphere control• Safe handling of reactive metals

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.
