In last week’s webinar we were joined by PolyOne for a comprehensive discussion on selecting the right thermoplastic material for injection-molded parts. If you missed the live webinar, it’s now available on-demand. The presentation by Jeremy Bland shares the characteristics of common thermoplastics and what steps to take when determining the right material for your application.
We have more webinars in the works! On October 27, we’ll hold the third and final installment in our series of ‘Designing for 3D Printing’ webinars. We’ll share tips on how to design parts for selective laser sintering. Click here to learn more and sign up.

Designing for 3D Printing: Direct Metal Laser Sintering
- DMLS design considerations including surface finishes, internal features, stresses, and support requirements.
- Reducing multi-part assemblies into a single component
How Rapid Prototyping Accelerates Medical Device Development
- Strategies to accelerate medical device development cycle
- Prototyping effectively and reduce design risk with rapid manufacturing
Last week we kicked off our webinar series on designing for 3D printing. The first session focused on stereolithography (SL) and it’s available on-demand here.
- Properties of commonly used stereolithography materials
- The unique benefits of stereolithography such as feature resolution and recommended applications
- General design tips for overhangs, support structures, finishes and more
Can you describe the resolution of SL parts in terms of microns?
There are 25 microns per 0.001 in. Normal resolution builds in 100 micron layers, high-resolution builds in 50 micron layers and micro-resolution builds in 25 micron layers.
The minimum X/Y resolution would be 250 microns in normal resolution, 100 microns in high-resolution and 50 microns in micro-resolution.
What’s the cost difference between normal- and high-resolution SL parts?
There’s no set number since it depends on the part’s geometry. But for parts under 1 in., customers will see a relatively low cost difference between normal- and high-resolutions.
Height is a primary driver of cost so once you start approaching 2 to 3 in. build heights it can start to differentiate more dramatically. But, with our instant quoting process it’s easy to compare these costs simply by clicking back and forth and comparing resolutions.
What’s the rule of thumb for wall thickness in hollow structures?
We try to stay above 0.03 in. and a general rule is 0.01 in. wall thickness per inch of the part. For example, a part that’s 8 in., you’ll want to shoot for 0.08 in. wall thickness for a well-supported hollow part.
More 3D printing webinars on the way…
The next webinar on our calendar will be on accelerating medical device development with rapid prototyping, which you can sign up for here. And, in the coming months we’ll have more 3D printing webinars that will focus on designing for selective laser sintering as well as direct metal laser sintering.
3D printing deserves an in-depth look. Whether it’s determining the right 3D printing process, selecting the right material or understanding design considerations, there’s a lot to think about.
Eric Utley, 3D printing application engineer
We’re kicking off a series of 3D printing webinars with each session focusing on one process so we can really take a close look at what makes each process unique.
Eric Utley, 3D printing application engineer at Proto Labs, will share:
- An overview of stereolithography
- Material options and recommended applications
- Design tips to improve surface finish, reduce cost and other benefits
After the presentation, you’ll be able to ask Eric any questions you have in an open Q&A session.
