3 Ways to Improve Operations with On-Demand Production

On-demand production of parts not only accelerates time to market, but reduces total cost of ownership since it eliminates the large capital expenses of traditional injection molding. Here are three ways on-demand production reduces your design risk, accelerates your product’s time to market, and saves you money along the way.

1. Bridge Tooling
Once you’ve finalized your product design, there’s often a gap between the end of product development and production. Leveraging rapid injection molding with cost effective, aluminum tooling can help you get to revenue more quickly while you wait for your production manufacturer to finalize steel tooling.

2. Supply Chain Emergencies
On-demand manufacturing provides a reliable alternative if global shipping delays or other disruptions in your supply chain arise—minimizing any potential loss of revenue. Further, products with high demand volatility can be more easily managed with on-demand manufacturing.

3. Low-Volume Production Runs
Before committing to large-volume production runs, validate your product design with low-volumes. Pilot runs can aid in testing assembly processes or gauging market demand. And, on-demand production is an economically viable solution for products with relatively low sales volumes—typically in the few thousands or hundreds of units.

3D Printing Design Fundamentals

Download “Design Essentials for 3D Printing”

3D printing opens up new design possibilities like hollow parts and complex organic geometries, but it’s still important to keep a few fundamentals in mind to take full advantage of 3D printing’s capabilities.

Understanding materials and processes as well as considerations like support structures and feature resolution are crucial for success. These design essentials will help you make the most out of your 3D-printed parts and accelerate your product development efforts.

In the following guide to 3D printing we focus on these topics:

  • 3D printing prototypes and fully functional, end-use parts
  • Designing for metal 3D printing
  • Comparing additive manufacturing processes
  • Material properties and selection

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.

WEBINAR: Designing for Stereolithography

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.
