3D Printing Fully Functional Parts with Selective Laser Sintering

Selective laser sintering (SLS) is an industrial-grade 3D printing process. It builds durable nylon prototypes and functional parts using a laser that “draws” slices of a CAD model in a bed of material, fusing micron-sized particles one layer at a time. The result is fully functional plastic parts that might have been otherwise challenging to manufacture using machining or injection molding.
This month’s tip discusses:

  • Properties and applications of various nylon materials
  • Managing the SLS build process
  • Design elements to improve eventual moldability
  • Surface finishes and post-processing
  • Maximum part size, achievable tolerances and other considerations.

An Inside Look at Advanced 3D Printing

We’ve watched a design move from 3D CAD model to final part. We’ve stepped inside high-speed CNC machine. And we’ve looked at how injection molding can produce quick-turn plastic, metal and liquid silicone rubber parts. We’re closing our video series with topic of many manufacturing conversations as of late: 3D printing.

Additive manufacturing (aka 3D printing) is increasingly being used to rapidly build prototypes and even functional, end-use parts. Proto Labs employs three advanced additive processes: stereolithography (SL), selective laser sintering (SLS) and direct metal laser sintering (DMLS). Check out our short video to see how additive manufacturing at Proto Labs can help on your next project.
