Review on 🔥 Polymaker PETG Filament 1: Unleashing High-Performance 3D Printing Excellence by Brian Samaiyar

Firstly, this filament prints smoothly and well on the simplest of machines after adjusting the temperature, speed, etc. This will create light to moderate lines between parts and boogers (or thin/underfilled walls), depending on the part, when more than one part is printed onto the plate, but these can be minimized by adjusting the temperature, time, print speed, and branch tuning. BUT, if you print one part at a time, you'll probably find that you get a good part on the first try. Why bother? Interlayer adhesion is functionally better than most (if not all) PLAs, and the softening point is high enough that hot tap water won't soften it (unlike most PLAs and even PLA+/PLA Pro), giving you many more options . functional parts. Also (and this is important) the tendency of large parts to deform from the build plate is much less than ABS. Threaded PETg allows you, depending on composition, to make parts harder and tougher but more brittle than ABS; and resistant to many solvents. For my Ender 3 Pro: build bed 75°C, extrusion 235°C, speed 25-40mm/s, retract by default, one or two slow starting layers (10-15mm/s). A low-density "criss-cross" type fill, such as B. the standard zigzag pattern of lines alternating at right angles may cause some problems with nozzle spot and scallop on the outer wall; Try ones that don't intersect, like the new Gyroid wildcard.
