A while ago I bought a roll of transparent petg "the filament" by spectrum. Wonderful, it printed great, shiny, smooth. I loved it.
Then I took advantage of the promotion on the Bambu lab website "4 rolls are discounted + free shipping" and I bought their transparent petg.
I opened the vacuum bag, loaded immediately in the printer and it strings and pops. Settings are correct as the slicer has a dedicated profile for this roll.
Their website says "warning: dry before using" - they mean that it comes already too moist from the factory?
Yeah, you should absolutely use a dryer. It's especially important if you want transparent prints since the slightest amount of water makes the print way less transparent.
Mine dryer is the cheaper food dryer I could find plus some 3 printer adapter walls so a filament roll fits.
It works very well and is likely better than many more expensive filament dryers.
The benefit of these is that they actively dry your filament as it rolls into the printer. At least mine does that which has been great to reduce the time needed to prep for my prints. Mine lets you set the temperature and it will keep that as it rolls in.
I heard about the food dryers but this was my choice also because I have limited space in my smaller home. This little box is about the size of a spool and sits behind my printer and I have it automated to turn on when I turn on my printer too.
Yeah, I wish I could print while it's drying.
It's probably possible to modify my solution to allow that but I haven't and I doubt I have the space for it.
