What Can You Actually Print?

1. The case for making things at home

When a household object breaks, the failure is usually one small part: a knob, a clip, a hose adapter, a latch, a battery cover. The rest of the appliance is fine. But the manufacturer has often discontinued the model, or will only sell the whole assembly.

A printed replacement changes that arithmetic. If the part can be measured or scanned, it can be remade — in a tougher material than the original, often, since the original was chosen to be cheap rather than durable.

2. Five things worth printing

• Repairs: discontinued knobs and handles, curtain sliders, wall brackets, battery compartment covers, clips for things that have lost their clip.

• Organisation: modular drawer inserts, under-desk mounts for cables and headphones, shelf brackets sized to your actual shelf rather than a standard one.

• Decor: lampshades, lithophanes, planters with the drainage arrangement you actually want, wall panels.

• Kitchen tools: cookie cutters, measuring scoops, spice rack fittings, jar openers — printed in a material chosen for food contact.

• Teaching: working gearboxes, planetary gear demonstrations, robot grippers, models that make a mechanical principle something a child can turn with their hands.

3. You do not need to own a printer

Owning a machine is one route. The other is to use somebody else’s. Through ModelForge you can browse models, configure colour and material with a live 3D preview, or upload your own file — and have the part made on our machines rather than yours.

That is the ecosystem part of the mission: the technology being available to people, whether or not there is a printer in the room.
