I have a new friend who is a microbiologist and a doctoral student in virology. He recently visited with his wife for the first time, and I thought that this lovely model of an animal cell would make a nice conversation piece and "welcome" gift for them. Had a blast printing it. Even with the E3D .6mm nozzle, the transitions are clean and lovely. A few of the overhangs initially had me considering whether I needed to add supports, but it printed just fine without any. I printed oriented with the bottom of the model/cell on the print bed, rather than as it is oriented in the .STL files.
Overture and eSun PLA Pro
Red, Purple, Yellow, Cyan
Sliced in Mosaic's canvas3d.io cloud slicer using automatic variable layer heights from .2mm to .35mm and 15% rounded infill. Transition tower length set to 100mm with 30% transition target (I believe I could've gone lower and still gotten clean transitions), with 5% minimum infill for transition tower.
Printed on my Frankenstein printer, which was originally a Prusa MK3s, but which has been modded to include Taurus Y axis, Bear X and Z axes, and the phenomenal BNBSX (Bunnysciences' Bunny and Bear Short Ears) extruder housing Slice Engineering's Mosquito Magnum hotend. Printed with an E3D .6mm nozzle out of various color PLA Pro filaments from eSun and Overture.
Lovely, clean model with a transition tower that wound up weighing about 2.5x the weight of the actual model.
