Why use Stereolithography?

Stereolithography (SL) works by using an ultraviolet (UV) laser that draws on the surface of paper-thin layers of thermoset liquid resin, creating solid layers. As each layer is completed, uncured resin is swept over the previous layer and the process is repeated until the part is finished. Those parts then undergo a UV-curing cycle to fully solidify them. 

Injection Moulding

Rapid injection moulding is perfect for on-demand production, bridge tooling, pilot runs, and functional prototyping. Our affordable aluminium moulds and quick turnaround times help reduce design risks and limit overall production costs.

CNC Machining process and capability

Quick-turn CNC machining works best for rapid prototyping, form and fit testing, jigs and fixtures, and functional components for end-use applications. We have hundreds of high-speed CNC machines that manufacture parts on time, every time.

3D Printing Process and capabilities

Industrial 3D printing is great for functional - rapid prototypes, complex designs, reducing multipart assemblies, and end-use applications. Our rigorous quality control measures and commercial-grade equipment create highly precise parts every single time.

PolyJet: What is it used for?

Ideal for medical devices and components, PolyJet 3D printing is able to create multi-material prototypes combining both rigid and elastomeric materials. Like other 3D printing processes, Polyjet 3D builds parts layer-by-layer, using droplets of liquid photopolymers which are then cured with UV lasers. 

Which Technology for Your Plastic Part?

Here at Protolabs we offer a variety of cutting-edge technologies to produce precision-engineered parts from a range of plastics, designed to suit your needs. From MultiJet Fusion (MJF) to Selective Laser Sintering (SLS) to Stereolithography, we can create the parts you need quickly and precisely. 

Differences in Major Material Types

Creating parts using 3D printing is easier than ever before, and prototyping and making design changes is fast, affordable and intuitive. The process offers a range of material types, from resin to plastic parts that are coated in metal, combining strength with lightness and flexibility. 

Multi Jet Fusion: What is This Used For?

For fast, quality results, MultiJet Fusion (MJF) is unparalleled as a 3D printing process. It’s able to produce functional nylon prototypes and end-use production parts in a single day, featuring quality surface finishes and fine feature resolution. 

Why is 3D Printing For Me?

3D Printing is creating a whole new world of manufacturing, with the ability to create complex designs with quality and precision and deliver faster, more affordable results. We use the latest 3D printing technologies to build parts in resin, thermoplastics and metal.

What is Industrial 3D Printing?

Protolabs is the world's fastest source for custom prototypes and low-volume production parts. Our high-speed 3D printing service uses advanced 3D printing technologies to create parts ranging from highly complex prototypes to functional, end-use parts.
