Problem Statement Current State : In 2017, an RIT MSD team (P18462) developed a 3D printing solution that combined solar energy and battery storage to overcome an unreliable power grid system. Desired State : The key goals of the project are to make improvements on the existing solar-powered 3D printer developed by RIT students. Project Goals : The power management system should be made more efficient and robust. Switching between solar and grid power should be seamless and the printer should fail gracefully when power cuts out. Constraints : The printer should be easy to package, assemble, disassemble and transport. The resulting solution should be sustainable with easily obtained materials.

Use Case Scenario

Customer Requirements & Engineering Requirements ● Capable of operation off of solar energy ● Power Consumption - Time (hrs) ● Consumes Plastic Pellets (not a Filament) ● Build Volume - cm^3 ● Increased functionality ● Start up time - Time (min) ● Fails gracefully when power runs out in the ● Total Mass - Kg middle of the print job ● Print Speed - mm/s ● Compact ● Device Size - m^3 ● Reliable ● Resolution - µm ● Capable of operating without connection to ● % Failures - % the grid ● Time to swap functionality - Time (min) ● Easy to Use ● Assembly & Disassembly Time - Time (hrs) ● Easy to assemble and disassemble ● Time to connect/disconnect to solar - Time (hrs) ● Minimum print volume ● Unit manufacturing cost - $ ● Low unit manufacturing cost ● Accepts Plastic Pellets - Binary(y/n) ● Easy to transportation ● Minimum print Speed *Key scope constraints given by the customer
