Manufacturing with copper vs. titanium
From copper's burnt-orange sheen to titanium's hard-edged reputation for endurance, these metals are as functional as they are distinct. Used in everything from electric vehicles and energy grids to aircraft, implants, and cutting-edge consumer tech, copper and titanium solve very different engineering problems. This guide compares them side by side so you can decide when to prioritize conductivity, corrosion resistance, strength, or cost.

What is CNC machining best for? How engineers use it in practice
Need a part that fits right, performs reliably, and doesn’t take weeks to produce? CNC machining makes it happen. Engineers count on it for its tight tolerances, wide material compatibility, and fast turnarounds—no tooling required. Whether you’re prototyping or scaling up with production orders, CNC machining gives you full control over geometry, functionality, and surface finish.

Simulation software in additive manufacturing
Simulation software helps you predict exactly how designs will perform long before hitting the build plate. This article covers how this powerful digital tool can transform your workflows, slash prototyping costs, and get you to market ahead of the pack.
Injection molded parts
Efficient high-volume injection molding for large-scale production
Injection molding is one of the most reliable ways to produce large volumes of high-quality parts, and digital manufacturing platforms are making it easier and more efficient than ever to scale production.

Your complete, practical resource for everything digital manufacturing

Digital manufacturing is a complex topic. There’s always more to learn, especially as designers and engineers develop astounding new technologies and manufacturing processes evolve (and automate). The more you know about manufacturing technologies like 3D printing, CNC machining, injection molding and sheet metal fabrication, the better equipped you are to design products that can be manufactured easily and at the price point that works for you.

For nearly a decade, Protolabs Network has worked to produce comprehensive resources to help you develop revolutionary products. These include The 3D Printing Handbook, our complete guides on every Protolabs Network technology and the Knowledge Base, a growing collection of articles for new and seasoned engineers. The Knowledge Base is a tool for learning about manufacturing technologies, how to design for every process, key standards and best practices and a lot more.

The manufacturing knowledge in this resource will help you develop products faster and more cost-efficiently, advising on custom part sourcing for any stage of the innovation process. Whether you’re creating an initial prototype, sourcing parts for a more functional prototype, looking to scale toward full production or making parts to bring an older product back to life, the Knowledge Base is here to guide you.
