Introduction
This page describes the modifications to the MOST Delta printer' as part of my graduate MY4777/MY5777/EE4777/EE5777 Open-source 3-D printing class project. This project enable the use of the MOST-delta printer off-the grid using solar power. These modifications not only makes the solar powered 3D printer a valuable tool for poverty alleviation and wealth creation in the developing world, but it also gives any 3D printing enthusiast the freedom to safely transport their printer to a remote camping site or any location of their choice. The modifications steps involved the following;
- PV system sizing - 60 W system.
- Coming up with the bill of materials (BOM).
- Designing and construction of a PV power supply system (fig.4).
- Designing and printing of solar panel holders (For safe transporting in a duffel bag) (fig.3).
- Design and printing of battery casing holder(mounted on top side of the top plywood board)(fig.5).
- Mounting the power supply under the top plywood board (inner-side).
- Design and printing the Melzi board casing (for protection during transit)(fig.6).
- Customized spool holder (easy to assemble) (fig.2).
