The e-NABLE community is constantly generating new tutorials, techniques, and workflows for designing and building low-cost 3D printed prosthetics. Here are a collection of resources spanning design, 3D printing, fitting, and hardware sourcing.
e-NABLE has developed the Handomatic web application to make it easier to create custom sized STL files for printing e-NABLE hands. Just select which component you wish to print, enter a couple of measurements, and generate your STL file!
e-NABLE hands require a little more than just 3D printed parts to assemble! Here we’ve collected the community’s go-to sources for elastic lines, high-strength tendon cable, Chicago screws, orthoplastic, and more.
e-NABLE hands require some special attention to detail when printing. Here we go over the basics of proper print orientation, material selection, printer calibration, and the specific qualities that we ask fabricators to target when printing parts for e-NABLE hands.
e-NABLE community members have come up with variety of small improvements to stable designs, including acetone vapor treatment for smoother surfaces on ABS parts, lubricating joints with beeswax, and using plastic rivets to assemble the joints of the fingers.
Fusion 360 is a cloud-based 3D modeling software tool that has professional capabilities but is far more user friendly than other professional solid-body modeling packages. It is a realtively lightweight install (800 mb), runs on both Mac and Windows, supports easy file sharing, version control, import/export of common CAD file types, and has powerful parametric tools and analytic mesh tools that are well-suited to the challenges faced in designing low-cost prosthetics. More on Fusion’s features can be found here.
Residual limb castings can be very useful in the fitting process as plaster casts of the body are much easier to 3D scan than the actual limb. Additionally, various thermoforming and fitting processes can be performed on the cast instead of the actual limb, which can make collaborating and fitting devices from a distance easier.
