PA12-CF Carbon-filled nylon. Printed to order, numbered by revision.


A smith in Hedeby worked one blade at a time and signed it. We do the same thing with a powder bed and a laser.

Every part here is printed, not moulded. That means no tooling, no minimum order, and no reason to freeze a design that could be better next month. When a customer finds a failure mode, the geometry changes and the revision number moves. Nothing sits in a warehouse waiting to be justified.

It also means each part can be built like nothing subtractive can — closed lattice cores, internal channels, wall thicknesses that vary across a single face. The knotwork on the outside is not decoration. It is where we put the material.

The rack

Eight parts in current revision. Built to order in 3–9 days.

One material, chosen once

Carbon-fibre-filled nylon 12, laser-sintered. Not the cheapest powder available, and the only one we run.

Every part ships bead-blasted and dyed through, so an abrasion scar shows black rather than white. Hardware is stainless throughout — no printed threads in anything that takes a load.

Where it gets made

Four sintering machines in one room, running overnight because that is when the power is cheap and the room is cold. A build takes about eleven hours. What comes out is a cake of grey powder with parts buried in it, and someone has to break it open by hand.

Then blasting, dyeing, hardware, and a lot of squinting at edges. A part that leaves here has been picked up by a person at least four times. That is not a manufacturing philosophy — it is just what the process needs.

Drops are small and they go quickly.
