Rapid prototyping

Rapid prototyping with 3D printing

Turn a CAD file or a sketch into a real part you can hold. Test fit, form and function in real materials before you commit to tooling.

Iterate fast, one revision at a time.

Rapid prototyping with 3D printing

Test your design before you commit

3D printing is the fastest way to hold your design in your hand. We print functional prototypes from your CAD file, a drawing or even a rough idea, so you can check fit, form and function before investing in moulds or tooling. Each iteration costs a fraction of a machined part, and production starts as soon as you pay.

We print in PLA, PETG, ASA and TPU, so a prototype can behave close to the final part: rigid, flexible, heat resistant or tough. Tell us how the part will be used and we recommend the material and, where it helps, a small design change for a cleaner print. You can ask for other materials, nylon among them, in a quote request, and an engineer answers.

Common prototypes include enclosures and housings, brackets and mounts, jigs and fixtures for the shop floor, and proof of concept models for pitches and testing. Send a revised file any time and we print the next version.

How it works

  1. 1. Send your files

    Upload your CAD model or a drawing, or describe the part you want to test.

  2. 2. Get the price on screen

    Upload your CAD model and the price appears at once, with VAT and delivery included, ready to pay by card. A drawing, or a part the site cannot measure, goes to an engineer by email.

  3. 3. Pay and we print

    As soon as the payment goes through, we print your prototype in Latvia.

  4. 4. Iterate

    Send a revised file and we print the next version. We ship across the EU and the UK.

Prototyping FAQ

How fast can I get a prototype?

We do not promise a fixed number of days. Production starts as soon as the card payment goes through, and we write to you when the parcel ships. The courier estimates 1 to 2 days in Latvia, 1 to 3 days to Estonia and Lithuania and 2 to 5 days in the rest of the EU and the UK.

Which material is best for a prototype?

Tell us how it will be tested. PLA for a quick visual check, PETG for functional indoor parts, ASA for outdoor or heat, TPU for flexible parts. For demanding mechanical loads nylon is the answer: ask for it in a quote request.

How accurate are the parts?

FDM printing is well suited to fit and function testing. If your part needs tight tolerances on a specific feature, tell us and we advise what is realistic.

Can you help fix my file for printing?

The site checks every upload automatically: closed surface, thin walls, separate bodies and size against the 325 x 320 x 325 mm build plate, and it offers to scale a model down if it does not fit. If that check cannot price your file, send it through the quote request and an engineer looks at it.

What files do you accept?

STL, 3MF, STEP, STP, OBJ and ZIP for models, plus PDF, JPG or PNG for drawings.
