Top 5 Reasons for SLS 3D printing

Have you ever wondered what the key advantages of Selective Laser Sintering are? We produced a video with our top 5 reasons that would make this powder bed technology the ideal choice for your next manufacturing project!

#1 Complex Geometries

Thanks to the precision of the laser, SLS can achieve what most conventional manufacturing methods can not: Parts with almost complete freedom of form and a high level of accuracy, without the need for support structures.

#2 Mechanical Properties

Compared to other 3D methods, SLS parts possess outstanding material properties. The most commonly used Polyamide 12 results in mechanically strong and impact resistant objects, that are well suited for end-use, even for industrial applications.

#3 Functional Parts

SLS generates the 3D object inside a powder bed, thereby eliminating the need for support structures. Unlike conventional manufacturing, this makes movable parts within themselves, undercuts and even overhanging structures a possibility.

#4 Material Diversity

Robust and durable, or ductile and soft: the range of SLS materials is already large today and grows steadily. Systems like the Sintratec S2 also incorporate a simplified material change, which enables users to quickly switch between powders.

#5 Production Rate

Unlike other 3D technologies, SLS allows you to densely stack your models inside the build volume. Combined with a fast laser speed and designated unpacking and powder refreshing stations, high throughput at a low cost per part becomes a reality.
