Custom Manufacturing Services

Get rapid prototypes and low-volume production parts in as fast as 1 day with our custom manufacturing services, including industrial 3D printingCNC machining and injection moulding services.

3D Printing

Manufacturing service parts made using DMLS 3D Printing

A 3D object is built from a CAD model, usually constructing the part by depositing layer upon layer of material. Protolabs offers five 3D printing services.

CNC Machining

Part made with CNC machining manufacturing service

Computer numerical control machining, or CNC machining, is the process of taking a blank piece of material and following a precise set of programmed instructions, to subtractively remove material from the block, until only the final product remains. Protolabs offers;

Injection Moulding

Part made using injection moulding

The process of heating resin and injecting it at pressure into a mould cavity, which then solidifies and sets, before being ejected. Protolabs offers;

Which digital manufacturing service is right for you?

Protolabs offers three manufacturing services: injection moulding, CNC machining and 3D printing.

The type of service needed to manufacture your part will depend on the purpose of the part, the materials needed to manufacture it, the complexity of the design and the required delivery time.

The table below details some of the most important considerations, which may affect your service choice, however, if you are still in doubt, or if you wish to discuss this with a member of the team then please feel free to contact one of our application engineers by phone on +44 (0) 1952 683047 or email [email protected]

Alternatively, please read our prototyping processes whitepaper for more in-depth information about the manufacturing services available at Protolabs.

Choosing a Rapid Prototyping Process

Each manufacturing process comes with its own unique advantages and disadvantages. From 3D printing to CNC machining and injection moulding. This white paper provides a technical view of the various rapid prototyping processes, to help you assess the benefits of each and enable you to focus on a process that's best suited for your project.
