Webinar: Designing for Overmolding

Join us for a webinar alongside RTP Company as we address common questions related to overmolding. We’ll discuss how to design more durable overmolded parts and what it takes to achieve strong adhesion between your part’s two materials.

gasket-overmolding

Overmolding produces two-material, plastic parts.

The presentation will include the following:

  • 12 key overmolding materials
  • Design factors that determine quality of flexible-to-rigid bonds
  • Methodology used to measure bonding strength
  • Differences between low- and high-volume overmolding

TITLE: Overmolding: TPE Multi-Material Molding, Achieving Melt Adhesion

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
DATE: Thursday, October 27 at 1 p.m. CDT

Can’t make it that day? You can still register and we’ll send you an on-demand version to watch when convenient. Also, feel free to forward this invite to your colleagues.

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: How to Choose the Right Thermoplastic with PolyOne

With thousands of thermoplastics on the market, selecting the right material for a run of injection-molded parts can be intimidating. To help make the process more manageable, we’re teaming up with the plastics industry leader, PolyOne, to host a webinar with tips on choosing the right thermoplastic material for your application.

TITLE: Thermoplastics: How to choose the right material for your application
PRESENTER: Jeremy Bland, Technical Dev. Engineer, PolyOne
DATE: Thursday, September 22 at 1 p.m. CDT

The presentation will include the following:

  • Factors in thermoplastic material selection
  • Overview of common thermoplastics including the effects of additives
  • An open Q&A session

Busy that day and can’t make it? Not a problem. You can still register and we’ll send a link to a recording that can be watched on-demand. As usual, feel free to forward to a colleague know if you think he or she will be interested in attending.

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
