Prusa i3 Improved for laser cut
Informatie (ENG):
We found latest Prusa i3 printer design, the one Josef Prusa showed at Makerfaire this year in New York, for its elegant simplicity, but hinge like connection between Y axis assembly and frame needed improvement, in our opinion.
Using CAD software we reworked Prusa i3 design:
- Laser cut frame was stiffen by adding two angle members connected to the rear side of Y axis assembly.
- Original, printed Z Axis mounting parts proven to be easy to break, which is why we replaced them with stronger laser cut parts.
- We did not like loose ends on Z Axis lead screw (similar to Printrbot design), therefore we added miniature flanged ball bearing on each side, to support lead screws on the top.
- All printed plastic parts were slightly changed, we felt that we should give them additional strength and better cosmetic appearance.
- Y axis assembly can be removed and installed back in a minute. Convenient for transportation or shipment.
- Dimensions and axis travels of original Prusa i3 preserved.
Instructions:
You will need (for now we using mixed SAE and metric parts):
Smoth Rods (8mm)
X-Axis: 2 x 15″
Y-Axis: 2 x 16″
Z-Axis: 2 x 12.5″
- If you purchase 36″ (1M) smoth rods, you will need 3 of them
Threded Rods:
5/16″
3 x 8.5″
1 x 12″
2 x 17.5″ (18″) - it will take total 2 x 36″ (1m)
5 mm for Z- Axis: 2 x 12″
We stil working on instructions and complete BOM.
Kit available for purchase.
Happy New Year to all!!!
