What is Selective Laser Sintering (SLS)

Laser Sintering also known as Selective Laser Sintering (SLS) builds complex parts directly from 3D CAD data via a heat laser that fuses or sinters powdered thermoplastics. Similar to other 3D printing technologies, it enables part consolidation and complex geometries, however, SLS is unique in that it eliminates the need for support structures. Parts built with SLS are printed in a bed of self-supporting powder; the excess powder is easily shaken out during post-processing.

The Process

3d cad model

Step 1: Design and Prepare the File

The 3D model of the part is created using CAD software. Slicing software is then used to slice 3D model into layers, in preparation for printing.

Step 2: Prepare the Printer

The ceramic-loaded liquid (slurry) is automatically dispensed and applied to a transparent vat. The movable build platform is dipped into the slurry from above, which is then selectively exposed to visible blue light from below the tub. The layered image is produced via a digital micromirror device (DMD) in combination with a state-of-the-art projection system. By repeating this process, a three-dimensional green part can be created layer by layer.

Step 3: Print

The FDM printer then melts the plastic filament and deposits it onto tray, building the part layer by layer from the bottom up. This enhances part strength.

Post Processing

After the 3D part is printed, it’s then left to cool and solidify so support structures can be removed and finishing can take place. This can be done by sanding or painting the part to match your design.
