Issues with Prusament Signal White PETG
HI @all, i wonder if someone else has the same problems with Prusament PETG signal white (and only with this). I printed a laundry detergent dispenser this time with PETG (last time with PLA) and i had really problems with the filament: it did not stick to two different build plates (satin and structured) and it did purge between the objects, though i had the recommended features and temperatures. After some failed attempts with other objects and much slower speed, different temperatures when i thought i couldn`t print anymore, i changed to a generic PETG in orange with the same slicer settings and had no problem.
I noticed that this specific filament is recommende 250° ± 10 while other PETG`s have 230°-270° range. Has someone made similar experiences?
White and some pastel filaments are often the trickiest to print with in any filament range; they contain so much pigment that they can become non-newtonian fluids when melted and they may be even more sensitive to moisture. The general advice to raise both the bed and print temperatures a little and to slow the print often helps but some batches are just tricksy and it can pay to make a couple of small test-prints with a new batch before committing to a bigger job.
Cheerio,

Thank you for your fast reply, i think will try a temperature tower

Cheerio,
so you mean something like this:
Have a nice day
RE: Issues with Prusament Signal White PETG
I agree with Diem. Many of these "whiter-than-white" filaments tend to be tricky, specially PETG. I print very often Geeetech black PETG with no problems, but one day I tried a white spool of the same brand and it was night and day. Every nasty trick that PETG likes to play on the user was there. No matter how well I dried that white spool, still troublesome. I had a similar experience before with Prusament PETG Terracotta. A very nice color color, but a PITA to print.
