Selective Laser Sintering

SLS - description of the process

Selective laser sintering uses a laser to fuse plastic material in powder form onto the component’s contour in layers. Lowering the building platform and re-applying a fine powder coat fuses the next layer on the object and the layers are joined to create a three-dimensional object in the powder bed. The intense heat in the compartment creates a compact, self-supporting powder bed, meaning that no support structures are required.

Benefits

Manufacturing partially through to fully functional assemblies with connecting parts, moving parts, or hinges in one piece
High mechanical strength and temperature resistance
No mechanical ageing of the components
Material is suitable for contact with foodstuff
Freedom of design for geometries that cannot be produced using conventional technologies
Good post-processing possibilities, e.g. for painting
