Rapid prototyping in Malta: how it works and what it costs

Most people asking for a prototype are really asking a question. Does it fit? Does it work? Does it look right in the hand? Will the client approve it? Each of those needs a different prototype, and the fastest way to waste money is to build one that answers all of them at once.

What is rapid prototyping, in practice?

Making a physical version of a design quickly enough that you can change your mind. With 3D printing that means a part in days rather than weeks, without moulds or tooling, so the second and third versions cost about the same as the first.

That last point is the one that matters. Prototyping is iterative by nature. A process where every revision means new tooling punishes you for learning something. Printing does not.

Which kind of prototype do you need?

Roughly three, and it is worth deciding before anything is made.

A form prototype answers "does it look and feel right?" Shape, size, proportion, how it sits on a desk or in a hand. Surface finish matters; mechanical strength mostly does not.

A fit prototype answers "does it go where it has to go?" Mating with another part, clearing a cable, sitting inside an enclosure. Dimensional accuracy matters most here, and it is usually worth printing the fit-critical section on its own first — faster, cheaper, and it tells you the same thing.

A functional prototype answers "does it actually work?" Clips that clip, hinges that hinge, brackets that hold weight. Material choice becomes the whole conversation. A part that works in PLA may fail in use for reasons that have nothing to do with the design — see how strong a 3D printed part actually is.

How long does a prototype take?

Usually days, and the printing is rarely the slow part.

The time goes on design if you do not have a file, on a round of questions about how the part is used, and on your own review. If you arrive with a finished CAD file and a clear purpose, the turnaround is about as fast as the printer and the courier. If you arrive with a sketch, add the design time — still days, not weeks.

What genuinely slows a prototype down is ambiguity. "Make it look premium" generates three rounds. "Matte black, 2 mm wall, the logo debossed on the base" generates one.

What drives the cost?

Four things, in roughly this order:

1. Design time, if you need us to model it. Usually the largest single item on a first prototype, and it happens once.
2. Size, because material and machine time grow with volume, not with length.
3. Finishing. A raw print is fine for a fit check; a client-presentation prototype needs sanding, priming and painting, which is hand work.
4. Iterations. The second version is cheap if the change is small and the file is ours.

There is no tooling cost, and that is the difference from every other route. Our general pricing approach is in what custom 3D printing costs in Malta.

When should you stop prototyping in plastic?

When the next question can only be answered by the real production process. If the final part will be injection moulded in thousands, there comes a point where a printed prototype stops predicting how the moulded part will behave. That is the moment to move on — and for many products, especially small runs, it never comes, because the printed version simply becomes the product. The trade-off is set out in 3D printing or injection moulding.

Can you prototype for us from outside Malta?

Yes. We ship across the European Union, and because Malta is in the EU there is no customs clearance and no import duty on a prototype sent to Milan, Munich or Lyon. For prototyping that matters more than it sounds: a part that sits in customs for four days has lost most of the "rapid".

Send the file, or the sketch, and the delivery address. Delivery is quoted with the job. More detail on shipping across the EU.

What we need from you

• A CAD file (STEP is ideal, STL is fine), or a sketch with dimensions, or a photo of what you are replacing
• What the prototype has to prove
• How many, and by when
• Where it is going
