Description

This page is dedicated to the design and development of an open-source Hands-Free Crutch for the developing world. All components are designed with open-source software. OpenSCAD, FreeCAD and/or Blender have been utilized for digital file generation (STL). All components have been printed on a MOST - Athena Delta Printer. This OSAT aims to decrease the overall cost of a standard crutch and to penetrate the specialized market by providing a 3D printed alternative by simultaneously allowing for customization based upon a user / patients condition and size (height, weight, leg size, etc...)

Materials and methods

This OSAT is in the prototyping stage. All prototypes have been manufactured out of PLA on a MOST Athena printer. Multiple operators and printers were involved in on the project, on average, the following printing parameters were utilized.

Temperature: 180 - 210C
Speed: 50 - 80mm/s
Skin: 1mm
Top / Bottom: 1mm
Layer Height: 0.2 - 0.3
