On-Demand Webinar: Improving Manufacturability with ProtoQuote

Last week we hosted a quick webinar that explored how designers can use ProtoQuote to improve the manufacturability of their design. It’s available on-demand here.

Key Takeaways

  • How to get free design for manufacturability feedback for your part
  • Improving manufacturability by adding draft, adjusting wall thickness and incorporating radii
  • How to navigate ProtoQuote for each of our processes: 3D printing, CNC machining and injection molding

Top Questions Asked

Will Proto Labs help simplify my CAD file?
Yes, along with our automated DFM feedback, we have a full staff of engineers that will work with you on simplifying your design. Once you upload a 3D CAD file, they will look at it and explore ways of improving overall manufacturability and provide guidance based on your part’s requirements and intended application.

Are there any general design tips to avoid parts having side-pulls or side-actions?
Our free design cube shows the different side-actions that we use to produce parts. And, if you have snap features on your part that might require side-actions, you can cut away that geometry and use a pass-through core to alleviate the need for a side-pull or cam.

We also have resources that discuss implementing side-actions, as well as eliminating the need for them:

What are the material options for opaque materials for lighting applications?
We offer polycarbonate materials that provide transparent options for lighting and other applications requiring transparent materials. We provide multiple PC colors: amber, green, blue, transparent and even infrared.

Stay Tuned
Look for additional technical webinars throughout the year on various 3D printing, CNC machining or injection molding topics. The next webinar will be part one in a series of 3D printing webinars and we’ll discuss designing for stereolithography.

Q&A: Rapid Manufacturing Fit for High-Speed Bike Design

Every year, cyclists converge in Battle Mountain, Nevada in pursuit of achieving speed records at the World Human Powered Speed Challenge (WHPSC). The competition is a mix of athletic performance, engineering and a seemingly endless number of variables. This past fall, Teagan Patterson, a Battle Mountain native and high-speed bicyclist, teamed up with Eric Ware and Mark Anderson to design a bicycle capable of capturing the world record — and her lifelong dream. 

Mark and Eric are veterans of the WHPSC having raced in 2009 with their vehicle, the Wedge, and reaching speeds above 70 mph — good for the eighth fastest time in the world and third fastest in American cycling history.

Drawing from their previous success, they worked with Teagan in preparation for the 2015 WHPSC, where they would try for another record.

Eric Ware knew Proto Labs from his day job as a mechanical engineer, so he decided to call us up for some machined parts for the bicycle design. In this Q&A, Ware gives a look behind-the-scenes at his team’s project.

Q&A: Eric Utley Discusses the Advantages of Stereolithography

Eric Utley, application specialist at Proto Labs.

We’ve been 3D printing for a while now, and our facility in Raleigh, North Carolina is packed with 3D printing specialists. For this installment of our Q&A, we spoke with one of those experts, Eric Utley, application specialist, for a chat about stereolithography and why product designers and engineers need it for prototyping.

To start off, can you give a quick overview of the stereolithography (SL) process?
Stereolithography uses UV light shot from a laser to cure a liquid thermoset resin called a photopolymer. In fact, even though 3D printing is often thought of as a new technology, SL has been around since the 1980s. But there’s a reason it has stuck around for so long — it has some key features that product designers need for prototypes.

What are some of those key features unique to SL?
I’d say the most important feature is that it creates a very high-resolution part with excellent surface finishes.

It can handle micro-sized features so it’s most suitable for parts that have a high level of detail. Most SL parts will have a nice, smooth finish and, although it’s typically used for prototyping, it leaves you with the feel of a final part — and looks go along way when sharing your new product design.

Another important benefit of SL is that it’s our most flexible process in terms of geometry it can handle, which gives designers a lot of freedom to work with.

Automation, Data, Testing and Iteration Dominate IoT Fuse

The second annual IoT Fuse brought together the Minnesota tech community for a day full of everything technology. The sold out conference connected engineers, developers, 

entrepreneurs and technologists to share how Internet of Things (IoT) technology is changing businesses with hands-on workshops, panel discussions and case studies. Among more than 40 presentations, Proto Labs VP Rob Bodor, shared how digital manufacturing and automation is accelerating the development of IoT products.

The World is Not a Desktop
The day opened with a fitting keynote from Amber Case, a “cyborg anthropologist” and UX designer. She presented the idea of calm technologies ­— meaning technology that follows these principles:

  • Technology should require the smallest possible amount of attention
  • Technology should inform and calm
  • Technology should make use of the periphery
  • Technology should amplify the best of technology and the best of humanity
  • Technology can communicate, but doesn’t need to speak
  • Technology should work even when it fails
  • The right amount of technology is the minimum needed to solve the problem
  • Technology should respect social norms

Much of Case’s message centered on the idea that innovation is not synonymous with over-engineered devices. She described how just a minor change like adding a camera to our mobile phones can be revolutionary.

She also referenced the groundbreaking research from Xerox PARC innovation center during the 1970s and 80s where they created what is now know as the graphic interface. Her point being that you can innovate faster by understanding the previous work of others.

Navigating Low-Fidelity and High-Fidelity Prototyping
Next, we heard from Eric Nyaribo, a design engineer at 3M automotive. He discussed strategies for prototyping and how engineers can use different types of prototyping to convey ideas and encourage interaction between team members.

He shared the concept of low-fidelity and high-fidelity prototyping and when one is more appropriate than the other.

A low-fidelity prototype is a rough concept or first iteration of an idea, it doesn’t have to be functional or pretty. Often a low-fidelity prototype is hacked together with spare parts.The main purpose of a low-fidelity prototype is to kick-off the product development process and inspire team members to share their ideas.

He defined a high-fidelity prototype as a product that is finalized with colors, design and is functional. As he said, “It’s that prototype you show to a customer and they want to keep it for themselves.”

One of Eric’s most valuable pieces of advice was that just because a prototype is closer to the final product doesn’t mean it’s the best kind of prototype for that point in the development cycle.

The value of a prototype isn’t in the model, it’s in the interactions, conversations and feedback they inspire. He also shared how prototyping helps reduce design risk since you can validate your design with small successes throughout the product development cycle. This helps gain support from key stakeholders and encourages the product team.
