About Tony Holtz

Tony is a technical specialist at Proto Labs with more than 10 years of experience ranging from CNC mill operator to mold designer to customer service engineer. While his formal education is in industrial machinery operations, he has extensive knowledge and experience in both traditional and advanced manufacturing processes and materials. Throughout his tenure at Proto Labs, Tony has worked with countless designers, engineers and product developers to improve the manufacturability of their parts.

TIPS WITH TONY: Design for Manufacturability (DFM) Analysis

Design for manufacturing (DFM) analysis provides information to not only improve the design of your injection-molded part at Proto Labs, but suggests improvements that can be applied regardless of your manufacturer.

Once you upload your 3D CAD model, you’ll receive an email inside of 24 hours — typically, within only a few hours — that contains a link to your quote. Quotes are generally defined as an estimated cost for a particular service, but arguably, the most valuable information that you receive in your Proto Labs quote is our automated DFM feedback.

The manufacturability feedback addresses considerations like:

  • Draft
  • Wall thickness
  • Undercut regions
  • Thin and thick sections
  • Material flow
  • Design complexity
  • Areas that cannot be manufactured
  • Gating and ejection

Proto Labs specifically uses this information to explain wall thickness and draft based on our manufacturing capabilities to machine an aluminum mold through three-axis CNC milling. These are unique to our manufacturing process, but are great guidelines to improving your part design in general.

Customers often times will begin designing a part with no draft or wall thickness concern and bring this design to our quoting software for a quick review at the end of the day. In many cases, by the time you arrive back at work, you may have your DFM analysis waiting. You can then apply those changes, or speak with one of our experienced customer service engineers who can help explain how to simplify your design or discuss why we have capability issues with how your part is intended.
