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

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.
RE: Issues with Prusament Signal White PETG
Basic rule. Calibrate EVERY filament to your printer. As stated in so many threads and forums. Not two filaments from anyplace have the same printing specs.
I learned this, early in my 3D printing days.
