OpenBox Printer
Why I made OpenBox
In 2020 I wanted a new 3D Printer. Till then I owned the Anet A8 and I was starting to reach the limits of what the machine could do. ABS prints were hard to print as they would warp, so I had to use a LOT of glue stick to keep prints adhere to the bed. The printer was loud and flimsy being made of laser-cut acrylic; it could only print with a single material and the build volume was merely ok. To top everything off it didn’t even print accurately with prints being a little skewed.
One of the problems was I was still in school so I couldn’t afford an expensive printer like a Prusa i3. And the Ender 3 didn’t have many of the features I was looking for, like multi material, silent stepper drivers and an enclosure to help with ABS prints. If I did buy an Ender 3 I would basically have to rebuild the printer… And then it hit me! If I can’t find the printer I want, I’ll just build one!
I was inspired by the OpenRC project to make my 3D printer open source (The OpenR/C Project – Daniel Norée (danielnoree.com))
NOTE: I’m working on the enclosure now and once that is done ill retake the photos with cleaned up wires!
What the design goals where
When I designed OpenBox I had some design goals the printer needed to meet, these design goals were
Build Goals
- Parts can be printed within a 220mm x 220mm x 190mm printer
- Easy to print parts with little to no supports
- Built around the 20mm T-SLOTTED aluminium extrusion
- No CNC cutting
- Off the shelf 3D Printer parts
- Easy to assemble
Functional Goals
- Large build volume
- Silent stepper motor support
- Dual extrusion
- Heated bed
- Enclosure
- Rigid design
- Swappable Print head
- Good print quality
