In our next webinar, we’re taking a look at medical device development. Specifically, how using rapid manufacturing can accelerate prototyping and get you to FDA submissions more quickly.
The presentation will cover:
- Reaching validation and FDA 510K approval fast
- Reducing costs with rapid manufacturing
- Selecting materials for 3D printing, CNC machining and injection molding
And come prepared with questions! At the end we’ll have an open Q&A session.

Already have plans that day? That’s okay. We’ll send you an on-demand version that can be watched at any time. Also, feel free to forward this invite to your colleagues.
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.
We’re kicking off an animated series that takes a quirky look at the fundamentals of molding. The first short video is on draft, one of the most important consideration during injection molding part design.
Check it out:
For more information on designing with draft, read our recent tip on 5 ways to improve part moldability with draft.
Our short video series continues with a look at the three different injection molding processes available at Proto Labs. See how we manufacture plastic, metal and liquid silicone rubber prototypes and low-volume production parts so fast.
Use CNC machining more? Take a spin through one of our high-speed mills. And if you’re curious as to how we’re able to turn your 3D CAD model into real parts in only a few days, check out our Art to Part video.
We talk a lot about our high-speed CNC mills, and how fast they crank out parts, so we thought we’d just take you inside one for quick second to have a look. Enjoy.
And if you’ve yet to see our first video that follows a design from sketch to final part, right this way.
