1. You upload a file
STL, 3MF or OBJ, up to 50 MB. The file goes straight from your browser into private storage — it never sits on a public URL and nobody but you and our review team can open it.
We then measure it on our servers: its real volume, its surface area, its bounding box, how many triangles it has, and whether the surface is properly closed. Those are measurements taken from your actual file, not guesses from its name or size.
2. You get a provisional estimate
From those measurements we work out roughly how much PLA the part needs and roughly how long it will sit on the printer, then apply our published rates. You see the whole breakdown — material, machine time, setup, finishing and delivery — not just a total.
This is an estimate, and we label it as one everywhere it appears. The print-time figure comes from the model’s size and shape, not from a slicer, so it can be out. Adjust the quality, infill and quantity and the estimate updates as you go.
3. A person reviews it
This is the part most services skip. Someone opens your model and looks for the things that ruin a print: walls too thin to hold together, overhangs that need support, detail finer than a nozzle can lay down, a part too large for the bed.
If something needs changing we tell you what and why, and you can send a new file. If we cannot print it at all, we say so and explain — and you have not paid anything.
Review is usually done within one working day.
4. You approve the final price
After the review we confirm the price. It may be the same as the estimate, lower, or higher — and if we have adjusted it, the reason is written on your order where you can read it.
You pay by card through Stripe. We never see or store your card details. Production starts once the payment clears, and not before.
5. We print and post it
You get an email when your order goes on the printer, and another with the carrier and tracking number when it is posted. We choose the carrier based on the size and weight of the parcel and where it is going.
Afterwards
Fourteen days after your order closes we delete the 3D file you uploaded. We keep it longer only if there is a dispute, a support case, a refund investigation or a legal reason, and we email you before it goes so you can ask us to hold on to it.
Your order, payment and refund records are kept separately, for as long as our accounting and tax obligations require. The privacy notice sets out both.
