THE ENGINEERIST: Fail Fast, Succeed Faster

Editor’s Note: The Engineerist is a three-part blog series written by Michael Corr, founder of Los Angeles-based manufacturing consulting firm, DuroLabs. This is part two.

Certification testing is expensive, especially when your product fails.

I was managing an engineering team several years ago when we submitted a new product with an injection-molded enclosure to UL for certification testing. The tests included a mechanical stress test with some rather extreme impact forces. This product was a deviation to a predecessor and therefore had legacy requirements which constrained our design options. With the time pressure we had to get the product to market, the mechanical engineering team and I were hoping a few modest changes to the existing legacy injection mold would be sufficient to pass the new certification testing and go into production. They weren’t.

Prototype Prep Before UL Testing
After a humbling blow to our egos and sizeable invoices from both the molder and UL, we took another approach. The ME team reviewed the points of failure of the plastic enclosure and came up with a few design improvements. But we didn’t want to risk failure again, and UL required testing parts fabricated from the actual production mold. It would be too expensive and risky if we were to modify the tool and fail again.

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

WEBINAR: Designing for Direct Metal Laser Sintering

In our next webinar, we’re focusing on direct metal laser sintering—our industrial 3D printing process for metal parts. Join David Bentley, our DMLS expert, to learn why product designers are turning to DMLS for prototyping and end-use parts. The presentation will include:

  • An overview of DMLS including materials and design guidelines
  • A case study on an innovative bike design
  • An open Q&A session

WEBINAR: Rapid Prototyping for Accelerated Medical Device Development

In our next webinar, we’re taking a look at medical device development. Specifically, how using rapid manufacturing can accelerate prototyping and get you to FDA submissions more quickly.

The presentation will cover:

  • Reaching validation and FDA  510K approval fast
  • Reducing costs with rapid manufacturing
  • Selecting materials for 3D printing, CNC machining and injection molding

And come prepared with questions! At the end we’ll have an open Q&A session.
