How to get the most accurate answer

The most accurate answer comes from a model or at least dimensions, intended use, quantity and preferred material. This lets us estimate material use, print time and preparation complexity.

How much does custom 3D printing cost?+

The price depends on model size, selected material, print time, infill and preparation complexity. The fastest way is to send an STL or STEP file and receive a concrete quote.

Which files do you accept for 3D printing?+

STL and STEP files are preferred. If you do not have a file yet, you can send a sketch, photo or description so we can check the modelling options.

Which material is best for my part?+

PLA is usually suitable for decorative parts, PETG for durable practical parts, TPU for flexible parts, ABS or ASA for higher temperatures, and PA, PC or carbon-fibre materials for demanding technical parts.

Do you print prototypes and spare parts?+

Yes. We print functional prototypes, jigs, tools, spare parts, signs, gifts and small batches when 3D printing is suitable for the intended use.

Use cases

Short case studies to support the decision

Three common scenarios show when 3D printing makes sense: from prototype to repair and a personalised product.

Functional prototype

Bracket prototype before final production

A fast physical sample helps verify dimensions, ergonomics and assembly before committing to a more expensive final version.

Challenge: The customer has a CAD model or sketch of a bracket, but needs to check whether dimensions, holes and handling work in real use before production.

Solution: We prepare the model for printing, select a suitable material for testing and produce a prototype that can be physically checked in place.

Result: The customer can quickly see what needs improvement and continue with a more reliable second version or final production.

Replacement part

Missing plastic part for repairing a device

When an original part is not quickly available, 3D printing is practical for small covers, spacers, holders and mechanical add-ons.

Challenge: The device still works, but a smaller plastic part is missing. The original spare part is difficult to source and waiting blocks normal use.

Solution: From a photo, old part, measurements or sketch, we prepare a printable geometry, recommend material and print a functional replacement.

Result: The product can return to use without waiting for tooling or a large minimum order quantity.

Personalised product

Custom 3D sign, logo or gift

3D printing makes it possible to produce expressive signs, labels and personalised gifts in small quantities.

Challenge: An event, business space or gift needs a unique product that cannot be bought as a standard item.

Solution: We prepare the sign or shape model, align colour, size and use case, then choose the material based on indoor or outdoor placement.

Result: The customer receives a product adapted to the brand, space or person without committing to a large production run.
