The first ever delta/quantum delta hybrid 3D printer.
Both the hotend and bed move independently with delta kinematics. Will be using RRF and even has a heated bed..
The printer is designed to be perfectly invertible - there is no right side up. 0.9 degree steppers and 16t pulleys are basically required to have decent accuracy at this scale..
This project exists as a proof of concept for an idea I have been considering for a while now - and one that many members of the 3D printing community are very interested in. Having a fully custom printer is a big step towards respect in the community, sponsorships from manufacturers, and most importantly, proof of my learning/knowledge. It will also be a great test bed for future ventures! (custom mainboard or hotend perhaps...)
Big thanks to 
for the idea and Rolohaun's Min Delta project as a big source of design inspiration.
Goals of This Machine --
- Maintain accuracy, despite the fact that all innacuracies are doubled due to two gantries.
- Develop the kinematics for a delta/quantum delta hybrid
- Have a test bed for future custom projects, non planar slicing, etc.
- Rigid Design with 2040 Extrusions and 10mm Linear Rods
- Printed Parts fit on an Ender 3
- Tiny Custom Heated Bed
- Self-Contained RRF with Ethernet
- All Nema 17 - even Extruder
- Remote cooling for both hotend heatsink and part cooling, using an aquarium pump and a modified form of CPAP, respectively.
