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
PRESENTER: Eric Van Roekel, SLS production manager

3D Printing Boosts Rocket Project for Engineering Students

University of Minnesota engineering students are readying a 3D-printed rocket engine for launch sometime later this year, with help from Proto Labs.

This cutaway view of the engine shows the cooling channel, which is one long tube that spirals down inside the wall.

David Deng, a senior aerospace engineering student at the U of M’s Twin Cities campus, is leading the extracurricular effort to design, build, and eventually fly a liquid-propellant rocket as project manager of LPRD Rocketry. The group’s name, pronounced “leopard,” is an acronym for Liquid Propellant Rocketry Design. The group includes aerospace engineering students and others studying electrical engineering, computer science, mechanical engineering, and materials science.

The primary design challenges the group faced included the small overall size of the engine itself, and the need to also somehow incorporate a cooling system inside the engine.

“The manufacturing of [the rocket engine] is incredibly difficult using conventional methods, especially for a very small engine,” Deng said. “The struggle was how do we [add] a single cooling channel through this entire engine, coiling around the side of it? That’s where Proto Labs came in. 3D printing is essentially the only way to get regenerative cooling on an engine this small and have it be a single channel.”


Webinar Round-Up: Thermoplastics, 3D Printing, and More

In last week’s webinar we were joined by PolyOne for a comprehensive discussion on selecting the right thermoplastic material for injection-molded parts. If you missed the live webinar, it’s now available on-demand. The presentation by Jeremy Bland shares the characteristics of common thermoplastics and what steps to take when determining the right material for your application. 

Upcoming Webinars
We have more webinars in the works! On October 27, we’ll hold the third and final installment in our series of ‘Designing for 3D Printing’ webinars. We’ll share tips on how to design parts for selective laser sintering. Click here to learn more and sign up.

Making the Steering Wheel Work

TRW Automotive’s clock spring design.

Most days drivers don’t give much thought to what happens when you press a steering wheel button. But it has been at the forefront of Rick Bowes’ mind for quite a while. Bowes is a designer in the body control systems group at Michigan-based TRW Automotive. The global company focuses on active and passive safety systems and has worked with Proto Labs for the past five years.   Continue reading
