HydraFabber
Note: document all progress here, and start Leo Log. See Marcin Log as an example.
HydraFabber - after HydraRaptor - is a portable, multi-headed CNC fabrication machine that can do 3D printing, circuit milling, and laser cutting. It is intended to be a portable machine that can be brought to OSE Design Sprints for prototyping. During the sprints, we design machines in Sketchup, and then prototype them by printing out modular parts with a 3D printer and laser cutter. The laser cutter cuts out flat sheets that are folded to make 3D beams and other parts, and these beams form 3D frames and other 3D parts. Then the circuit mill functionality can be used to prototype circuit boards, such as controllers for automated machines.
Specifications
- 1.5W laser cutter diode
- Hybrid of 3D Printer that is strong enough to handle CNC circuit milling
- Folds up into a portable suitcase so it can be brought to design sprints and other events
Process
Start with Window 7, presentation page 2 - concept design.
- Do Systems Engineering Breakdown Diagram
- Potentially do an interface design that shows how modules fit together
- Then embed the original i3 RepRap STL via an STL Viewer in the wiki
Notes
- Leo's RepRap Kit had at best 4/5 print success on 8 hour overnight prints. Mechanical failure is typical culprit.
- For short prints, once print parameters are established for a particular object for a particular printer with a particular material. Once you are dialed in, ~1% failure rate for prints of 1 hour. This is for unambitious - ie, safe zone - prints. Wall thickness safe, etc.
