Webinar: How to Design Efficient Parts for Rapid CNC Machining

Join us for a live webinar on rapid CNC machining. The presentation, hosted by our technical specialist Tony Holtz, will share how to design quality, machined parts.

During the webinar, you will learn how to:

  • Reduce manufacturing costs by simplifying part design
  • Select materials to improve part functionality
  • Design with moldability in mind to better prepare for injection molding

In addition to general design considerations, we’ll discuss how to leverage rapid manufacturing processes for accelerated product development.

Webinar Round-Up: Overmolding Principles, Designing for Machining, and More

In our most recent webinar, we looked at 12 key factors to help you design durable overmolded parts. If you missed the live presentation, it’s now available on-demand. The webinar covers the overmolding process and design principles that determine the quality of flexible-to-rigid bonds.

Learn how to design for overmolding.

THE SHORT LIST: 4 Ways to Leverage Rapid Overmolding

Rapid Overmolding is the latest addition to our injection molding service. Now, you have a fast way to create injection-molded parts with two different materials. We use a pick ‘n place method.

That means we follow a two-step process. First we mold the substrate part. Then we place the substrate part into the mold and a second material is injected to form the final, two-material part.

Here are a few benefits of rapid overmolding.

Vibration dampening: Dampen vibration by adding liquid silicone rubber to parts made of hard plastic, like ABS, or if it’s a handhold device (think toothbrush), it can even be used to improve grip.

Fast, flexible volumes: Often, manufacturers will not process low-volume overmolding orders, but now you have the ability to manufacture 25 to 10,000+ overmolded parts within just a few weeks.

Simplify multi-part assemblies: Reduce cost and save time spent assembling parts by combining two materials in one molded part.

On-Demand Webinar: Designing for Stereolithography

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.

Key Takeaways

  • 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

Top Questions

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.
