Models printed in SLA, FDM and SLS
FDM vs. SLA 3D printing
Whether you’re prototyping or producing end-use parts, the choice between FDM and SLA can shape cost, design flexibility, and overall quality. FDM is known for its affordability and accessibility, while SLA often wins on detail and surface finish. In this guide, we’ll explore both technologies, so you can find the right fit for your project.
The fastest 3D printing techniques
When it comes to 3D printing, speed isn’t just a luxury—it’s often the most important factor for engineers. Processes like binder jetting and DLP are blazing trails in speed, while SLS and FDM balance efficiency and complexity for functional parts. Learn more in this knowledge base article on how to 3D print with speed and precision.
What are metalloids and how are they used in manufacturing?
Every time you use your smartphone, drive a fuel-efficient car, or check the time on a smartwatch, you’re benefiting from the peculiar properties of metalloids. These elements, which bridge the gap between metals and nonmetals, play a critical role in creating lightweight, high-performance components across industries. This article will break down what metalloids are, why they matter, and how they’re shaping the future of manufacturing
How does TIG welding work?
TIG welding, or tungsten inert gas welding, is the precision craft of the welding world. It’s all about clean lines and strength. Whether you’re building something for aerospace or crafting sleek welds for automotive projects, TIG welding gets the job done beautifully. This article will cover how it works, its benefits, and how to get the best results.
CNC machining, 3D printing and sheet metal fabrication parts

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.
