Selective Laser Sintering – SLS®

FEATURES AND ADVANTAGES

With over 10 years of experience in selective laser sintering associated with state-of-the-art equipment, we can help you best exploit the benefits of polyamide powder “sintering”. The prototypes obtained offer excellent mechanical and thermal characteristics. This technology is ideal for your assembly or functional validations. The parts can be used plain or with a paint finish.

MANUFACTURING PROCESS

Your parts are made by stacking layers of CO² laser-melted polymer. This process is used to manufacture extremely complex geometries. In a pre-heated chamber, a powder with a polyamide base (nylon) is deposited on a manufacturing platform. An infra-red laser beam melts the powder specifically in the areas corresponding to the part. Upon solidifying again, the upper layer fuses to the lower layer, therefore gradually forming the part. The major advantage of this technology is the fact that manufacturing supports are not required, leaving room for your creativity. Shapes are practically limitless with this process.

LASER PROCESS

Manufacturing cycle

• Polymerization of the layer
• Shift the platform downwards, layer by layer (e.g.: -0,15mm)
• Re-coat = Arrange a uniform layer of powder on the entire work surface
• Heat the layer
• Polymerization
• Repeat…

This process does not require drying in an oven afterwards.
