What is SLS 3D Printing?

Selective Laser Sintering (SLS) 3D printing is one of the most advanced and versatile 3D printing technologies available today. Unlike traditional manufacturing methods, which often involve removing material from a solid block, SLS builds objects layer by layer from a powdered material, using a laser to fuse these particles together. But what exactly does this mean, and why is it so revolutionary?

How Does SLS 3D Printing Work?

The process of SLS 3D printing can be broken down into several key steps:

1. Design: The journey begins with a digital 3D model, usually created in CAD (Computer-Aided Design) software. This model is then converted into a format readable by the 3D printer, typically an STL file.
2. Preparation: The STL file is uploaded to the SLS 3D printer’s software, where the model is sliced into thin layers. The printer’s build chamber is filled with powdered material, such as nylon or polyamide.
3. Printing: A high-powered laser scans each layer’s cross-section, selectively fusing the powder particles together. The build platform lowers slightly after each layer, and a new layer of powder is spread over the surface.
4. Cooling and Cleaning: Once printing is complete, the build chamber needs to cool down before the printed parts can be removed. The excess powder is then brushed off and can often be recycled for future prints.
