Last updated: 5 October 2026 · Total: 8 products
Not every prosthesis comes from a large manufacturer. This page gathers projects that aim at lower cost or wider access. Among the 3D-printed and open-source hands and arms are the e-NABLE Phoenix Hand, a volunteer-made device closed by bending the wrist, the Victoria Hand and the Limbitless bionic arm. Koalaa makes soft fabric prostheses with interchangeable tools. A second group covers low-cost legs, knees and feet designed for regions with few clinics. Many of these are supplied through charities or partner clinics. Suitability should still be checked with a prosthetist.

How to choose
- Ask how the device is supplied, since some come through charities or clinics and are not sold directly.
- Check whether a design is a certified medical device or a community project offered without that status.
- Printed plastic hands suit light grasping and play, so set expectations lower for heavy or wet work.
- Find out who will size, assemble and repair the device near you before committing.
Guides for choosing affordable, 3d-printed and open-source

What a prosthetic leg really costs and who pays
A prosthetic leg is a fitted service, not a boxed product. Here is what the bill is made of and which funding routes to ask about first.
Common questions
Are 3D-printed prosthetic hands as good as commercial ones?
They are usually simpler and less durable, with limited grip force. Their strengths are low cost, low weight, fast replacement and custom looks, which is why they are popular for growing children.
What does open-source prosthetic mean?
The design files are published freely, so anyone with suitable equipment can print, build and modify the device. Quality then depends on the builder, the printer and the materials used.
