DESIGN TIP: 6 Ways to Cut Costs with 3D Printing

Reduced cost of development as well as part production can certainly be achieved with industrial 3D printing processes, like selective laser sintering and direct metal laser sintering, but there are a few design rules you need to keep in mind.

Here is DMLS in action, as the machine sinters each layer. This process is repeated layer by layer until the build is complete.

This month’s design tip from Proto Labs discusses:

  • Optimizing part design for 3D printing
  • Embracing non-traditional design techniques like organic features
  • Designing for manufacturability if larger quantities are needed
  • Minimizing overhangs and other unfriendly features
  • Avoiding “over-tolerancing” your parts
  • Factoring in your product’s overall functionality in addition to cost reductions

Webinar: Designing for Selective Laser Sintering

This is the final part in our series of “Designing for 3D Printing” webinars. Just as we’ve looked at stereolithography and direct metal laser sintering in previous webinar, this presentation will provide insights into how to design for selective laser sintering (SLS), a discussion on material options, and recommended applications for SLS.

Post build

The presentation will include the following:

  • Comparison of SLS materials
  • Design guidelines for functional prototypes and production parts
  • Moldability considerations for effective development
  • Open Q&A session

TITLE: Designing for 3D Printing: Selective Laser Sintering

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.
