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.

Already have plans that day? That’s okay. We’ll send you an on-demand version that can be watched at any time. Also, feel free to forward this invite to your colleagues.

DESIGN TIP: Cutting Corners on Injection-Molded Parts

Sharp corners definitely have their place in part design, but they often spell trouble when injection molding plastic parts. Accordingly, designers should be aware of the pitfalls associated with “being square” when developing parts. Indeed, part accuracy, strength, and aesthetics suffer without the right amount of corner rounding and filleting.

This month’s design tip explores ways to strengthen injection-molded parts while reducing costs with proper placement of corner radii and fillet. You’ll learn about:

  • Material selection. Some plastics are more forgiving of sharp-cornered parts. Choosing the right one for your application is a necessary step towards accurate, functional parts.
  • Wall thickness. Beefing up adjacent walls may absorb some of the stress associated with sharp internal corners, but can create other design challenges.
  • Part geometry. Some parts are simply more “moldable” than others. Achieving proper form, fit and function depends on sound part design, a large piece of which is appropriate corner radii.


WATCH: Talkin’ Cosmetic Defect Blues

The next short video in our Fundamentals of Molding series takes a trip down the Mississippi River to explore different cosmetic flaws like sink, warp and blush, which can find their way into injection-molded parts.

NEW JOURNAL: How Technology is Transforming Injection Molding

The new issue of Proto Labs Journal is out and includes a cover story focusing on the digital transformation of injection molding. A related, second feature story explores the pros and cons of printed plastic molds.

The cover story reports on how automating the front-end of the manufacturing process has reinvented injection molding, and served as a game-changer for the entire industry.

The related feature, “3D-Printed Molds,” advises product designers, engineers and developers to take a careful look at part finish, size, design capabilities, mold longevity considerations and cost when comparing printed plastic molds to aluminum tooling.

Elsewhere in the Journal, look for our Eye on Innovation feature, which highlights cool new products and technology you should know about.

EYE ON INNOVATION: Proto Labs Salutes ‘Smart’ Companies on MIT List

The 50 Smartest Companies for 2016, as compiled by MIT Technology Review in its recent annual list, combine cutting-edge technology with effective business models.

In our on-going quest to seek out and identify innovation in manufacturing and technology, we salute these companies that, as the MIT folks say, “are ‘smart’ in the way they create new opportunities.”

In fact, we’re pleased to serve as a prototyping and low-volumes production parts supplier for a number of these companies (though non-disclosure considerations prevent us from identifying which ones we work with). We do take satisfaction in knowing that our digital manufacturing prowess has, in key ways, helped nurture the innovation these companies are being recognized for.

As the Review reports, some of this year’s stars are giant corporations like Amazon and Alphabet, which, “are using digital technologies to redefine industries.

Others are wrestling with technological changes: companies like Microsoft, Bosch…and Intel.” Automotive leaders such as Toyota and Tesla Motors are also on the list. Plus, you’ll find ambitious startups too, such as 23andMe, an innovator in consumer-accessible DNA testing.


Eye on Innovation is a monthly look at new technology and products.
