3D Printing Oxygen Valves for Low Resource Settings
The Goal of this Challenge is to design a life-saving medical device that can be 3D printed out of acrylonitrile
butadiene styrene (ABS) thermoplastic using fused deposition modeling (FDM) desktop style printers.
To win, create a 3D printable oxygen splitter that allows you to independently control oxygen flow rates (in liters per minute) for two patients sharing one oxygen tank who are receiving supplemental oxygen via nasal cannulas. This will help conserve oxygen use, which is a precious commodity in low-resource settings.
Our aim is to support those who work in the worst context around the globe to save life's of the most vulnerable. The winning designs will be available for an unlimited humanitarian usage of the design solutions.
Your entry must include:
• Preferably designed in OpenSCAD (www.openscad.org)
• Rendering of your design preferred
• Videos of the printed objects being used preferred
• STL file formats
Printed entirely out of ABS on a desktop FDM (range 20 – 250 microns, ex. Cube, Makerbot, Lulzbot) on a heated or non-heated 15 x 15 cm print bed
No post-processing of printed object (i.e., no support material, filing or sanding)
Preferably designed in OpenSCAD (www.openscad.org) to allow free customizability
Judging criteria will be based on achievement of accomplishing criteria listed above, including:
1. Printability: how well it prints across a range of desktop printers and material colors
2. Functionality: how well it works, how easy it is to use, can it fit a range of oxygen tank outlet valves
3. Cost: the lower, the better; consider power usage and material costs
