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.


For a lengthier examination on avoiding cosmetic defects when designing for injection molding, read our free white paper.

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.

CASE STUDY: A Sea Change for Sailboat Winches

The story of how Proto Labs helped a French company with a revolutionary sailboat winch design started with a daring adventure at sea.

Pontos, the Saint Malo, France firm that’s reinventing sailboat winches, was co-founded by Michel Chenon and Darryl Spurling in 2010 after, as they describe it, a “hair-raising” close call that brought their sailboat dangerously close to the rocky outcrops of the narrow straits off the island of Brehat, France.

The boat was equipped with a winch for the hoisting and furling of the sails that proved to be too physically challenging for the inexperienced crew to use.

This adventure led the two, along with a research and development team, to spend an intense three years creating and perfecting — with the help of Proto Labs’ rapid manufacturing services — the design of what would become a game-changing new line of sailboat winches. These now award-winning winches would also eventually be used on sailboats that would win or be competitive in several notable yacht races and regattas worldwide.


IoT-Enabled Water-Management System Wins Cool Idea! Award

The developers of AgPulse, a water-management system that uses wireless technology and the internet of things to optimize watering and irrigation for farms, have been presented with the latest Proto Labs Cool Idea! Award, a service grant given to innovative companies.

AgPulse, developed by California-based Mist Labs, Inc., uses a set of wireless soil sensors to continuously monitor and optimize farm, vineyard or orchard irrigation, though it can also be used for backyards and gardens.

Mist Labs used the Cool Idea! Award grant from Proto Labs to manufacture its custom-designed components that were injection molded using high-strength polycarbonate in order to withstand the conditions of an agricultural environment.

“Water is a valuable commodity,” says Proto Labs founder Larry Lukis. “This product will help conserve this important natural resource and help all of us, whether we’re large-scale farmers or backyard gardeners, to use water more efficiently.”
