Laser sintering 3D printing service

Laser powder sintering (SLS) 3D printing is an additive manufacturing method that uses a laser to melt and fuse thin layers of polymer powder to create three-dimensional objects.

The printer successively deposits a thin layer of powder (0.1 mm) on the production unit, and the laser then melts this powder point by point to harden the material. The part is created by successively stacking these layers.

The advantages of powder laser sintering 3D printing are numerous. This technology enables the creation of highly complex, high-precision objects with high thermal and mechanical capacities, without the need for expensive tools or molds. Particularly suited to functional parts, laser sintering is tough and durable.
As the Laser Sintering process is based on a powder bed, parts are produced without support, which is particularly useful for articulated parts, meshes, etc.

Low production costs and rapid time-to-market make laser sintering a popular technology.

This technique is used in many sectors, including aeronautics, automotive, energy, industry, military applications...
Laser sintering is ideal for the creation of complex-shaped parts, functional and resistant prototypes and mass production, such as inserts, screws and clips.

Parts manufactured by powder laser sintering have a higher mechanical strength than those produced by other 3D printing techniques.
Certain materials, such as polyamide (nylon), are suitable for physical testing and functional use in real-life conditions. Polyamide is ideal for mechanical parts in the aerospace, automotive and electrical industries. This material has good thermal stability and limits fire propagation in the event of a fire, and has been awarded JAR 25 certification, the aviation acceptance criterion. Its chemical resistance is equally high.

A glass-bead-filled PA compound makes it possible to produce a functional part with extremely high strength. Typical applications for this material are housings and covers requiring high rigidity and meeting fire-retardant and ultra-high-strength standards.

In addition, laser sintering makes it possible to create parts with specific mechanical properties such as resistance to heat, pressure and wear, often required in industrial applications.

The surface finish of parts manufactured by laser powder sintering is relatively rough, and depending on your project, your part may require finishing to achieve a smooth, uniform surface.
Sandblasting, adding epoxy resin (to seal the part) or primer, painting and varnishing are some of the finishes available to achieve the desired surface.

Some applications do not require a smooth surface, as is often the case with prototypes and molding tools.
