Inspired by the tree trunks I saw on Thingiverse I wanted to create some trees with leaves for a sculpture. I carefully designed this tree so it would not need any supports and the tree would be balanced so it could stand on its own - though it is designed to be glued to a flat surface. The design is entirely my own.
This actually worked for the small tree (90 mm high) although it does need a large brim (8mm) which I taped down. Then I scaled it up to 180 mm and made four attempts adjusting parameters to reduce jerk, stray wisps of filament, etc.. which all failed. One pic shows the small tree and a failed large print.
The problem was the tree is so top heavy so any tiny thing - a small filament blob, a tiny tug from a too hot strand of filament - becomes enough to hit the nozzle and pull the whole print over. Finally I gave up, rotated the print horizontally on its side, and used supports (no brim needed). I did set the support width to 3mm width and Slic3r supports pull off very easily. Any roughness can usually be left alone hidden in the trunk bark or the tree leafy top.
Printer:
Prusa Original i3 Mark3S
Rafts:
No
Supports:
Yes
Resolution:
.2mm
Infill:
15%
Filament: AIO PLA Dark Grey
Notes:
A small print (up to 90mm high) can be printed with a large brim (8 + mm) and no supports. Be sure to tape the brim down when the trunk is high enough to be out of the way.
Larger prints need to be printed horizontally with supports.
