3D Printable Thermometer Jar for UNICEF Supply Catalogue
Project developed by Zachary Verran
- UNICEF's supply catalogue is used to acquire commodities to respond to the needs of children and their families worldwide. In this catalogue, there is a product for use as a thermometer jar. In the catalogue, it is specified what the jar is made out of, the dimensions of the jar, and what the jar needs to be capable of. In the catalogue, it specifies that the jar needs to be made of plastic (polypropylene) and be able to be autoclavable, which means it needs to have the ability to be steam cleaned and sterilized. Following the dimension guidelines set in the catalogue, a 3D model of a jar was created using OpenScad and then printed used a RepRap Athena Delta Bot printer. The jar was printed using PLA, however the model can be printed using polypropylene filament if the proper adjustments are made to the printer and print parameters. It is thought that PLA is also capable of being a viable material for this jar, however more research in this area is needed.
Bill of Materials
- PLA printer filament from PushPlastic for model of product
- OR Polypropylene printer filament found at GIZMODORKS PP Printer Filament
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
- Knowledge of 3D printing as taught by the MY477 Class at Michigan Technological University.
Technical Specifications and Assembly Instructions
- No assembly necessary for this device, simply print the part using the desired infill.
- The infill used for the most recent prototype was 15%, however more research can be done to optimize the infill percentage for the given use.
- With 15% infill, estimated print time is 3 hours and 45 minutes with a print speed of 50mm/s.
- Layer height: 0.20
- Shell, bottom and top layer thickness: 1.0
- Technical Specifications:
- Material: Polypropylene, autoclavable.
- Internal diameter: approximately 30mm.
- Depth: approximately 110mm.
- Overall height: approximately 120mm.
Common Problems and Solutions
- No assembly necessary, only problems with device is printer issues, which can be solved using the Most Delta Google group for example.
- Cost of print based on material usage and $30/kg for filament:
