Three failed prints, but learning how do deal w a cold shop and long prints. After a spiral print was buckling, I put a tent (photo booth tent) over the printer. Then sliced it with two walks and 5% infill. I got good results but was trying some new pla filament and running the Ubis 13S w/o a fan with a heater blowing it. Fail! It’s time for a legit plastic tent with a heater that has a thermostat. Maybe try figuring out a heated bed of some sort too. It’s frustrating to hit ambient temperature problems due to a cold shop. Maybe my wife will let me put it in the living room maybe not.
Tomorrow a fan for the Ubis 13S and more prints. Ultimately I’ll need to get some ridiculously long prints under my belt before trying large molds. Spiral prints may unlock the ability to do some very fast and interesting prints but it doesn’t really help the goals of the project at hand - printing a huge Hughes H-1 Racer. It’s amazing how strong (and heavy) a 2 wall, 5% infill is with a 1mm tip laying down .8mm extrusion! The molds will need to have more infill just to support bridging over the infill.
