I'm not sure if I simply got a bad batch of this filament or the rest of the reviews were made by people who never printed anything with the filament! I can't speak for other colors, but the "Shiny Silk Multicolor Rainbow" filament simply sucks! Here's why I make this claim: I purchased the rainbow filament at the request of a friend who wanted a vase printed in rainbow colors, and liked the "shiny silk" look of the example. I'll caveat what I'm about to put here with "I'm NOT new to 3d printing, and I own 2 Prusa Mk3 printers and an ANET printer, so I think I have a clue about what I'm doing." I sliced the requeted vase in Prusa Slicer 2 using high-quality 0.15 layer height and set the PLA filament temperature at the mid-point of the range listed on the spool; which typically gives pretty decent results with other filaments. I started printing and got great bed adhesion through the first 8-10 layers, so I let it continue. I went back a few hours later to check on the status and found about 40 layers printed fine, then without warning, no more filament being extruded. Hmmm... jam; I can fix this. Cleared the print head and restarted the print. This time, I get maybe 70 or 80 layers printed and it does the exact same thing: suddenly stops extruding. ok, maybe it's a bad slice, so I repeat it using the hottest end of the range listed on the spool. Exact same results. Ok, so lets try this on one of my other printers. Hmmm... surprisingly, exactly the same results! I took the exact same model and printed with some cheap 3DSolutech filament without re-slicing, and it printed perfectly.
ok, so, next step: I throw the spool into my dry-box and turn the dehydrator settings up to full-blast for a day to make sure I have good, dry filament, then re-start the print using this filament again (mind you, this is after a few successful prints with other filaments). Guess what?!?! Exactly the same results as before!
Summary: When the filament stopped extruding, it was NOT on a color change boundary in the filament; it was at seemingly random spots. The filament got stuck in both the Prusa printers bondtech gears (on both printers) causing worn spots in the filament (and not able to feed); the filament got stuck between the extruder gear and idler on the ANET and a large worn spot formed in the filament (and not able to feed). Printing the exact same sliced model with different filament worked fine. You be the judge, but beware of this filament!
