Notes on the Prusa Slicer
Supports Speed and Material usage
I have part that takes 30 meters of filament. It is a boiler for a train so it is like printing a cave. I tested with grid and organic supports and this is what I found.
I have been using PS, Prusa Slicer 2.6.0 in
beta and now the production. I have primarily been interested
in Organic supports.
Some notes on organic supports.
Post processing time of this train boiler with Grid supports was almost 2 hours and gloves are needed. Very easy to get cut. There is a lot of supports to remove and they don't remove easily even in PLA. The longer to remove the supports, the more chance of damaging the part. Based on my experience with other parts with organic supports, I estimate the support removal will be down to about 10 minutes or less with organic supports.
With post processing included, overall time may still be equal or faster with organic supports. Less problems removing the supports also decreases damage caused by post processing.
I haven't run the train boiler on the MK4, I have made the part on an MK3S+ with grid supports. Once the Input Shaper for the MK4 is in production, I plan on running the part and see how fast it is.
PS fixes, wants and bugs in 2.6.0
Fix: Merge a negative volume so we can export a resulting .stl Prusa Slicer 2.6.0 should have it! June 2023
Want: Slicer, 1 master and copy routine. Be able to choose number of copies at print time.
Bug with rafting and organic supports: If 4 or more raft layers, the organic support generation hangs and never finishes. It has been reported and confirmed. Hopefully a fix in Prusa Slicer 2.6.1 is available.
