5 Common Rapid CNC Machining Questions

TIPS WITH TONY

Most are familiar with machining, but what makes it unique at Proto Labs? These are a few of the most common questions we receive about our rapid CNC machining service. These answers will help you optimize your design for CNC machining and determine how it can improve your product development efforts.

CNC-Machining-Block-Plastic

CNC machining is a subtractive manufacturing process that mills away at a block of solid plastic or metal.

1. What is unique about Proto Labs’ CNC machining process?
In order to efficiently machine low quantities as fast as possible, we do things a bit differently compared to a traditional machine shop. When you upload a 3D CAD file to protolabs.com, our proprietary software analyses the design, creates a quote, and generates the CNC toolpaths. By automating the front-end of the manufacturing process, we can machine a part in as fast as one day.

2. How does the quoting process work?
Once you upload your 3D CAD model to our website, the software calculates the price—not a budgetary estimate—to machine your design. Within a few hours, you’ll receive an email with an interactive quote. Here, you can select different materials and quantities and receive real-time price updates. The quote even contains a 3D-view of your machined part, which will highlight any differences between the machined part and the original 3D CAD model. See a ProtoQuote preview here. Continue reading

Webinar Round-Up: 3D Printing Materials, CNC Machining, and More

We wrapped up 2017 with two webinars on rapid manufacturing. First, we discussed how to design efficient parts for CNC machining. Then we shared tips on how to select the right material for your 3D-printed parts. Both are available on demand.

Stay tuned for what’s to come in 2017. We’ll be kicking off the new year by looking at how to leverage on-demand production to reduce manufacturing costs and manage demand volatility.

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.

The presentation will include the following:

  • Factors in thermoplastic material selection
  • Overview of common thermoplastics including the effects of additives
  • An open Q&A session

Busy that day and can’t make it? Not a problem. You can still register and we’ll send a link to a recording that can be watched on-demand. As usual, feel free to forward to a colleague know if you think he or she will be interested in attending.

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.
