PP Filament 1.75mm Polypropylene Filament, Gray 1kg/2.2lbs Durable Semi-Flexible 3D Printer Filament for Functional Parts & Prototyping, No Warping, 5 Build Sheets Included

Very good filament. Took a few setting changes and a lot of glue for the plate.

Around 2% shrinkage pretty consistently. Cannot get rid of warping trying all the usual things.Settings are as recommended and refined based on testing. Getting some usable prints, but lots of waste. Bought 3 spools, should probably return the others.Plastic PP build plate adhesive sheets work <50% of the time, lifting up off the build plate due to warpage. Magicgoo PP works 100% so far.A lot of these problems are typical of many PP formulations, but the ad copy is false based on my experience. It should not make claims it cannot back up.The biggest issue, and the one that almost made me return an opened spool, is the way the filament was wound. It was so tight, then loose, and uneven that the extruder could not reliably feed filament. I had to unwind and waste a lot of filament before it got down to where it would feed properly. Just poor attention to detail when the spool was loaded. This wasted almost a day trying to get the spool to feed, checking the printer, checking the feed paths and messing around until I unwound a bunch of filament to get to what looked to be evenly wound layers. Very frustrating and totally not worth the time and effort.Can't recommend if this is the norm for this brand. Not worth the hassle.

It wrap a lot no matter what

Aunque el color, negro en este caso, es muy parejo y agradable, las piezas se rompen muy fácilmente. He tenido que reponerlas a mis clientes pero se vuelven a romper.

Es un material malo cuando la pieza se completa, tuve muchos problemas con la contracción del material ni siquiera el warping me dio tantos problemas, solo he podido imprimir un par de piezas con deformidad
