What happens after you send a brief.

Tell us what the piece has to do, where it'll be used and what it has to prove, and say how many you need and when you need them. We follow the same five steps whether it's one prototype or a production run.

Send the geometry you already have, in whatever form you've got it, and we'll agree the format with you. If you haven't got geometry yet, we can model it with you. If you haven't decided some of this yet, just say so and we'll work it out with you.

The same form covers a business briefing a prototype or a production run, a training team asking for a demonstration model, a school ordering classroom pieces, and a shop stocking a range. It asks for your name, your organisation and your email, the kind of work, the quantity and what the piece has to do. The date you need them is optional. Send the brief and we'll reply by email.

Yes. We send you a sample to approve before we make the full run. When you approve it, you're approving the design, and we make the run to match it.

If a piece in the run does not match the approved sample, or is damaged or faulty, we put it right.

Lab test documentation from the filament manufacturer comes with the parts and the models. There's more on heat, sun and washing in how to look after a PLA piece.

The Certified range has full ingredient transparency and EN 71-3 chemistry evidence for the colours in that pack, so choose it when a buyer, school or venue wants the documents. The Premium range doesn't include ingredient transparency or EN 71-3 evidence. When a school needs the documents, we make the pieces in the Certified range. Our toys are UKCA tested where relevant, with documentary evidence.

For our own training models, we write down every design value with its source. If the brief is for a demonstration model, read what a printed training model can and cannot teach before you send it. It's a training and demonstration model, not a medical device. It's not for clinical use, and it's not a clinical validation.
