Med Device Conference to Showcase Advancements

EYE ON INNOVATION

Innovation drives successful companies, and med device and med tech firms are no exceptions. At Proto Labs, we’re proud to be a supplier for a number of these innovative companies and help them swiftly move medical and scientific advancements to the marketplace.

Proto Labs staffers Jenna Nyman, left, and Peter Douglass, right, met with industry professionals at last month’s Autodesk University conference in Las Vegas. We’ll be at BIOMEDevice next week in San Jose.

This med tech innovation will be on display next week (Dec. 7 and 8) at BIOMEDevice at the San Jose Convention Center in San Jose, California. We’ll be there, too, in booth #707. We invite you to swing by our booth and say hello.

The conference will bring together nearly 3,000 industry professionals and more than 300 med tech suppliers. Keynotes, workshops, and other sessions will explore a stunning variety of topics: cybernetic technology, biocompatibility testing, bio-absorbable polymers, Industrial Internet of Things, mobile health, FDA regulations, wireless medical devices, intellectual property regarding med device development, and more.

Proto Labs is providing custom-machined aluminum-joint housings for this powered exoskeleton.

We look forward to participating in this event, given that product developers at med tech companies turn to our prototyping and quick-turn production services to reduce design risk, accelerate development, and launch new products in less time.

A couple of recent examples of our med-related work include projects with Wicab, Inc., a Wisconsin company that’s developing and launching wearable technology for the blind; and the University of Houston, which is developing a powered exoskeleton (see prototype, pictured) that may help paraplegics walk again.

See you in San Jose!

Webinar: How to Design Efficient Parts for Rapid CNC Machining

Join us for a live webinar on rapid CNC machining. The presentation, hosted by our technical specialist Tony Holtz, will share how to design quality, machined parts.

During the webinar, you will learn how to:

  • Reduce manufacturing costs by simplifying part design
  • Select materials to improve part functionality
  • Design with moldability in mind to better prepare for injection molding

In addition to general design considerations, we’ll discuss how to leverage rapid manufacturing processes for accelerated product development.

TITLE: Designing for CNC Machining
PRESENTER: Tony Holtz, Technical Specialist at Proto Labs
DATE: Thursday, December 1 at 1 p.m. CST

If you can’t attend the live event, you can still register to receive an on-demand recording afterward. And, if you have any colleagues that may interested, please feel free to forward this invite.

Take Full Advantage of CNC Machining’s Capabilities

Product designers in need of prototypes or end-use parts frequently turn to CNC machining for its quick-turn capabilities. Machining isn’t new, but just like any other digital technology, its functionality has expanded in recent years.

That’s why we assembled some tips for how to get the most out of today’s CNC machining. This will help you design higher quality machined parts and better use CNC machining to bolster your product development efforts.

Our Design Essentials for CNC Machining covers the following topics:

  • Designing cylindrical parts to be turned
  • Threading
  • Transition from 3D printing to machining
  • Outsourcing to a machine shop
  • Cost reduction tips for CNC machine

Augmented Reality Emerges as a Tool for Engineering Design

EYE ON INNOVATION

Virtual reality (VR) may be garnering a lot of media buzz these days, but augmented reality (AR) is gaining traction as a technology that offers practical applications for engineers, designers, and technicians.

Big names are getting involved, too, including Microsoft and Autodesk, which have recently teamed up to pair Microsoft’s HoloLens AR headset with Autodesk’s Fusion 360 engineering design software.

Though still in the formative stages of development, AR-enhanced design software will help developers to visualize designs, view CAD model holograms, and see how new or replacement components and parts might fit on existing products. A recent article in Mechanical Engineering Magazine, for example, showed how AR allowed designers to visualize new motorcycle cladding and a fuel tank cover on an existing bike (see photo).

How does AR work?

Unlike VR, in which you put on glasses or a headset to fully immerse yourself in a virtual world, AR taps into technology to enhance the world around you. Also using glasses or a headset, AR dangles text, graphics, or video into users’ visual fields that describes, or augments, what they are looking at. Continue reading

THE ENGINEERIST: Designing with Moldability in Mind

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 three. The first two installments can be found here.

Intelligence does not automatically equate to experience, and in hardware, product development experience goes a long way.

I was recently hired to take over management of an engineering team at an early-stage company. A team of mechanical, electrical, and firmware engineers was already in place, and while I noticed they were younger than most teams I’ve managed before, I was incredibly impressed with their intelligence and creativity. That energy of young and enthusiastic engineers was a convincing factor for me to accept the position.

An Introduction to Manufacturability
Since the team had already released products to customers, I took a passive approach and just observed the established processes while they worked on the next version of the product. I injected comments and feedback on occasion, but trusted them to repeat their existing methods as they prepared for production. However, the more I got involved in reviewing the designs, I realized there was a common theme across the younger engineers—moldability was not factored into their designs. Many of the mechanical prototype parts coming off the Stratasys desktop 3D printer were designed to satisfy the performance requirements, but would at best, be expensive to manufacture, and at worst, impossible.

Adding draft angles to design helps facilitate ejection of a part from a mold, and improves overall moldability. The exact degrees of draft angles are dependent on part geometries.

I took several of the MEs aside and asked a few direct questions challenging them on how they envisioned an injection mold being designed for their parts. Blank stares were the only answers I received. I pointed out that one design had an undercut and another had no draft angles for clean part ejection. Again, blank stares. That’s when I realized that these engineers had become trained on producing parts using 3D printing tools only. While 3D printing has a made tremendous impact in prototyping and even production-grade parts, it also has its caveats. Continue reading
