Selective Laser Sintering

At ADDform, we use SLS printing on the Formlabs Fuse 1+ 30W to rapidly produce strong, high-quality nylon parts. A powerful laser fuses polyamide powder layer by layer, enabling complex geometries, excellent durability, and production-ready results without support structures.

Why choose SLS?

Selective Laser Sintering (SLS) – Powered by Formlabs Fuse 1+ 30WSelective Laser Sintering (SLS) is an advanced additive manufacturing technology used to produce complex geometries and strong, functional parts directly from 3D CAD data.

Using our Formlabs Fuse 1+30W, we deliver high-quality SLS parts with excellent mechanical performance, accuracy, and repeatability.The Fuse 1+ 30W uses a powerful 30-watt fiber laser to selectively fuse nylon-based powders, such as polyamide, layer by layer. This enables the production of durable parts with fine detail and uniform material properties, all without the need for support structures. As a result, complex internal features, moving assemblies, and lightweight designs can be manufactured efficiently in a single build.SLS parts produced on the Formlabs Fuse 1+ 30W are ideal for functional prototyping, end-use components, and low-volume production. With fast turnaround times and consistent results, this technology is perfectly suited for engineers, designers, and product developers who need reliable parts that perform as intended.

How Does SLS Printing Work?

The 3D CAD model of the part is sliced into thin cross-sectional layers using specialized software.
A layer of powdered material, typically nylon or polyamide, is spread evenly across a build platform.
The SLS printer's laser is used to selectively fuse the powder particles together to create the first layer of the part.
The build platform is lowered by one layer thickness, and a new layer of powder is spread across the previous layer.
The laser fuses the powder particles together to create the second layer, and the process is repeated until the entire part is complete.
Once the part is fully printed, it is removed from the build platform and any excess powder is brushed or blown away.

SLS Materials

Advantages Of SLS

One of the main advantages of SLS printing is that it does not require support structures, as the surrounding powder provides support during the printing process. This allows for the creation of complex geometries and intricate details that would be difficult or impossible to produce using traditional manufacturing methods.
