Selective Laser Sintering (SLS)

Printing with SLS gives you:

• White nylon parts that can be dyed
• High dimensional accuracy and intricate details
• Smooth surface finish
• Good uniform strength in all directions

Applications:

• Scenarios where natural Multi Jet Fusion parts are too dark
• Functional prototypes
• Small-batch production
• Bellows and gaskets
• Living hinges and snap fits

Selective Laser Sintering uses thermal energy from a laser to bind cross-sections of polymer powder one layer at a time. Once the entire cross-section is scanned, the build platform moves down one layer and the process repeats. The result is a bin filled with parts surrounded by unsintered powder. When printing is complete, the parts are removed and the unsintered powder is recycled and reused in the machine for future builds.

Support structures are not required for overhangs and undercuts as the powder from each previous layer acts as the support. Post-processing steps can then be employed to improve visual appearance, such as dying or polishing.

SLS printing technology produces strong end-use parts and functional prototypes with outstanding resolution, surface finish, and edge definition. It allows us to provide a cost effective solution for low-volume production without the need for expensive tooling.
