I have been printing mono color lithophanes with good results. Went from 0.4 to 0.2 nozzle for finer detail. Knew it would take longer and it was, about 3 times. So 6 hours for one print seems reasonable to me. Print looked great. Got the Bambu CMYK to try. Knew there would be time and waste incurred there also.
But, exact same print that was 6 hours mono was showing 7 days 15 hours (was over 8 but removing the prime tower removed a full day). Flushing is showing 1097 grams, I am guessing that would all be waste? Is this the reality of CMYK? How do you tune this? Print would be about 85 x 107 x 4 mm.
Printer is P1S. About the only thing I changed from default was adding an outer wall brim. And no, I can not make the STL file available. Sorry.
Going to a 0.14 setting reduces it some but it is still over 6 days which seems rediculous to me. I was looking at a video of someone doing a larger, more colorful print on an A1 (0.2 nozzle) and it was only 10 hours to print. When I tried their settings it actually added over a day to my print time.
Is that print really stood up vertically? No wonder it has 2557 colour changes!
Try orienting it so it is flat to the build plate. I’ve only just started doing CMYK lithophane prints myself, but I’ve getting ~6 hours on A1 with a 0.4" nozzle.
16 filament changes. If I stand the same print vertically, I get 2d7h and 1472 filament changes… er… no! This is for a 144mm x 108mm by probably 4mm thick print.
Exactly! I had actually looked at that just before coming on here to update this and saw your response. I had seen a mention that vertical requires a lot more color swaps. So I left it flat and even with the 0.10 high quality setting on 0.2 nozzle the time (no prime tower) came out to 9h18 m. Only 3 hours more than the vertical mono color, which I would expect. The flush also went down to only 13g.
