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.
