Additive Manufacturing, CNC Machining, Injection Moulding

Proto Labs is the world’s fastest digital manufacturing source for custom prototypes and low-volume production parts.


The technology-enabled company manufactures custom parts for a global-base of designers and engineers through three distinct services: additive manufacturing, CNC machining and injection moulding. Our proprietary software and automated manufacturing processes allow for quick-turn prototyping and low-volume production of real plastic, metal and liquid silicone

Cosmetics White Paper
There are a lot of factors that can affect the cosmetic appearance of injection-moulded plastic parts. Our in-depth white paper on cosmetics addresses the importance of part geometry, material selection and mould design in minimising or eliminating cosmetic flaws like sink, knit lines, flash, burn and other issues that can arise during moulding. By knowing the solutions to cosmetic issues early, you can improve the final appearance of your injection-moulded parts.
Designing for Mouldability: Volume 2 White Paper
In our second volume on designing parts for mouldability, we dig deeper into some of the more complicated design challenges that product designers and engineers face. If your part has complex features that require undercuts and through-holes, see how the use of side-actions, sliding shutoffs and pickouts can be used mould those features.
Designing For Mouldability
Every process has its guidelines and limitations. Injection moulding is no exception, and Protomold’s rapid injection moulding process has a few additional requirements of its own. Our free 16-page guide will show you how to get the best possible results.
Materials Matter White Paper
There are more than 85,000 commercial options for plastic materials listed in materials databases. Needless to say, narrowing down that extensive list of materials can sometimes seem like a formidable task. Our comprehensive white paper provides a highly technical observation of thermoplastic resins and their properties for engineers who want to quantitatively analyse a part; determine loads, stresses, strains and environments; and make material decisions based on the analysis.
3D Printing White Paper
There are many different additive manufacturing processes to choose from, each with its own advantages and disadvantages. Our white paper examines the various 3D printing technologies — SL, SLS, DMLS, FDM, PolyJet and others — being used by today’s product designers and engineers to build better, faster products.
Liquid Silicone Rubber White Paper
Our comprehensive white paper on liquid silicone rubber provides a detailed look at the injection-moulding process and offers guidelines to achieve better moulded LSR parts. While there are some shared similarities to thermoplastic injection moulding, LSR is a thermoset material with a unique set of design characteristics.
Prototyping and Low-Volume Production for the Medical Industry
Speed to market is everything when it comes to development of medical components and devices. This comprehensive white paper examines various rapid manufacturing options available to today’s medical design engineers and product developers. From 3D printing to injection moulding, explore the strengths and weaknesses of each process as well as material options best suited for your particular application.
Prototyping Processes White Paper
Whether you’re a newbie, expert or in-between, our Prototyping Processes white paper will help you choose the best process for your project. It’s packed full of excellent info on strength, finish, material properties, and more.
