Selective Laser Sintering

Laser sintering is a popular and versatile 3D printing technology thanks to its high precision, design freedom, and wide range of production-grade materials. Suitable for all stages of the production lifecycle, from prototyping to small series or custom manufacturing, laser-sintered parts need no support structures, making it possible to produce even the most complex geometries.

Discover applications of laser sintering

Black cable twist wheel for aircraft, printed in PA 12 using laser sintering
3D printing made it possible to develop a lightweight, ready-to-use cable twist wheel for aircraft cables, with an innovative double-acting hinge.
Interior view of laser sintered nozzle for creating multi-colored marshmallows
Using PA 12 (SLS) as the final part material made this marshmallow nozzle ten times less expensive than a conventionally manufactured stainless steel nozzle.
Small, snap-lid bottle laser sintered in polypropylene
High elongation at break makes laser sintered polypropylene the perfect choice for functional prototypes that require frequent movement, such as hinges.
Grey QualiCal shaft level indicator shown with red lid
Honeycomb structures and performance thermoplastics allowed QualiCal to revolutionize the design of their shaft level indicator, slashing downtime.
Series of connectors used in building Maggie Shelters, laser sintered in Bluesint PA 12
Seeking a sustainable solution, the Maggie Program printed connectors for their temporary shelters using Bluesint PA 12, which is made from 100% re-used powder.
