Bought a spool of Bambu Silk PLA and it can’t even feed through the .4mm nozzle without completely gumming up and jamming. I’ve tried using the Bambu Studio profile, and tried the temp up and down in 5 degree increments up to 250 with no success. New printer (December 20) which has been printing like a champ on all other PLA spools, but this one I just cannot get to work. No hydration issues - climate/moisture controlled space. Any ideas would be most welcome!
Thank you!
If its just that spool, and it is in fact dry, and youre using the bambu profile…The roll must be junk somehow. I do print silk filament slower than normal filament.
I would personally dry it longer.
Sometimes a spool of filament is just damaged beyond use.
I have rehabilitated ABS that was completely unusable by heating it on the print bed to 75C for 2-3 hours. I think the equivalent PLA drying temp is 50C, but I’ve never had a problem with PLA.
Filament can also be hydrolyzed in a way that damages the plastic bonds in an way that is unrecoverable.
Just based on the forum comments about PLA silk, it seems more prone to becoming unusable, and unrecoverable.
I have been successful making some pretty art objects with PLA silk, but it was always ‘interesting’ to use where Basic PLA has always been just dead easy.
Good luck,
I switched to 0.6mm nozzle for all my Silk filaments and have much better success since then, no clogs at all, whereas on the 0.4mm had constant clogs.
