A good rule of thumb is to apply 1 degree of draft per 1 inch of cavity depth.
There are multiple paths to injection molding. Some parts are first prototyped through 3D
printing where moldability considerations are of limited concern. Others take a more
traditional machining route that allows for iterative testing in engineering-grade materials
similar to that of molding. And many simply jump right to injection molding.
Before production begins, there are important design considerations that will improve the
moldability of the parts, and ultimately, reduce the chance of production hiccups,
cosmetic defects and other issues.
In this month’s design tip, we walk through these key design elements:
If you didn’t attend Autodesk University this week in Las Vegas, here is one big item you missed. Autodesk announced the launch of Forge, a $100-million investment fund to support the creation of a cloud-based platform that will connect design and manufacturing ecosystems in an effort to help developers bring new ideas to market faster and more often. We at Proto Labs are excited to be one of Forge’s inaugural partners in this effort.
As a result, Autodesk Fusion 360 users now have seamless access to our design for manufacturing analysis and web-based, interactive quoting right from Fusion 360 CAD program. “We are excited to bring this seamless quoting and ordering process to the Fusion 360 users and look forward to continued collaboration with Autodesk on the Forge platform,” said Rob Bodor, Proto Labs’ Vice President and General Manager, Americas.
Meanwhile, in the exhibitors’ area at Autodesk’s annual event, Proto Labs representatives talked with a variety of attendees, including electrical, civil and mechanical engineers and various educators (below).
Minnesota’s Lt. Governor, Tina Smith, and Proto Labs CEO, Vicki Holt, talk shop.
Proto Labs is at MD&M Minneapolis this week (Wednesday and Thursday, Nov. 4-5) in conjunction with Minnesota Medtech Week. Stop by booth #327 to talk with manufacturing experts, learn about newly launched capabilities and, of course, see prototypes and parts in all shapes and sizes made by our 3D printing, CNC machining and injection molding services.
We kicked today off with a visit by Lt. Governor of Minnesota, Tina Smith, who met with Proto Labs CEO Vicki Holt to discussed the state of Manufacturing and Proto Labs’ efforts.
At this week’s show, we’re all about speed-to-market and reducing development time, so Proto Labs will be participating in the following two conference sessions:
Our technical specialist, Tony Holtz, will be at the Tech Theater stage on Nov. 4 at 2:30 p.m. talking about prototyping and low-volume production for medical applications. He’ll go in-depth on how to accelerate the development of medical devices and quickly launch products to market.
Eric Utley (our expert on everything 3D printing) will also be participating on a panel discussion titled “Going Beyond Prototyping: Accelerating Regulatory Approval and Speed-to-Market” on Nov. 5 from 1 to 1:40 p.m. The group will evaluate common pre-development design failures, how to differentiate prototypes from final products, and tactics to better analyze the composition of prototypes versus final products.

Selective laser sintering (SLS) is an industrial-grade 3D printing process. It builds durable nylon prototypes and functional parts using a laser that “draws” slices of a CAD model in a bed of material, fusing micron-sized particles one layer at a time. The result is fully functional plastic parts that might have been otherwise challenging to manufacture using machining or injection molding.
This month’s tip discusses:
Properties and applications of various nylon materials
Managing the SLS build process
Design elements to improve eventual moldability
Surface finishes and post-processing
Maximum part size, achievable tolerances and other considerations.
Earlier this week, our CEO, Vicki Holt, appeared on Fox Business’ “After the Bell.” She explained how Proto Labs’ digital manufacturing capabilities — from advanced 3D printing to quick-turn CNC machining to rapid injection molding — have enabled product developers and design engineers to iterate faster than ever, bringing products to market at an unprecedented speed.
