3D Printing Service - Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) is a 3D printing process that uses a laser to fuse polymer powder layer by layer. It produces strong, precise plastic parts with isotropic properties and a slightly granular surface – ideal for prototypes and small-batch production in areas such as aerospace, robotics, medicine, and consumer goods.

Standard service – For SLS printing, glass bead blasting is included. This removes loose residual powder, smooths the surface, and improves the quality of the components.

Material Selection for SLS

When selecting materials for SLS (Selective Laser Sintering), the intended use of the component is crucial. SLS materials – especially polyamide (e.g., PA12) – are characterized by high strength, good temperature resistance, chemical resistance, and uniform mechanical properties. Since no support structures are required in the SLS process, complex geometries and functional components can also be realized. Depending on the application, the material can be optimally selected for prototypes, durable functional components, or series production.

Nylon 12

SLS

Nylon 12 Powder is a versatile, biocompatible material offering high accuracy and fine details. It is suitable for prototypes, assemblies, and robust end-use parts with good durability.

Nylon 12-GF

SLS

Nylon 12 GF Powder is a glass-filled, biocompatible SLS material with high stiffness and heat resistance. Ideal for rigid prototypes and end-use parts that require dimensional stability under demanding conditions.

SLS 3D Printing: Advantages and Disadvantages at a Glance

Benefits

No support structures needed – the powder automatically supports overhanging geometries.

Complex shapes possible – cavities, lattice structures and movable parts in one print.

Robust materials – durable, resilient, temperature and environmental resistant.

Fast production – Your parts are usually ready for shipping in 2-4 days.

Small series and individual pieces – efficiently producible from one part to many components.

High precision – tolerances from ±0.1mm" to ±0.25mm".

Colorability – Parts can be subsequently colored to achieve individual colors.

Disadvantages

Rougher surfaces – Compared to SLA or FDM, the surface is coarser, with a typical roughness of 100-120 µm.

Limited materials – Currently available: Nylon 12 and PA 12 GF (glass fiber) in dark grey.

Color options - Only one color per printed part is possible, no multicolor printing.
