No affiliation or anything. I’m simply stoked!
Elegoo Rapid PETG. I like PETG, but with my printer (Ender 5 Plus, slightly tuned; DD, All metal hotend, dual gear extruder, accelerometer…) regular PETG is sloooow. I’m already up to 180 mm/s it prints beautifully. As with all PETG it likes to be thoroughly dry. Once dry it prints like a PLA+. Beautiful definition.
I paid about 15€ per roll, but buying a 4 pack, it comes to about 12,50€ per roll, so about the same as PLA.
I’m just not buying regular PLA, or PETG anymore. The new generation of materials just leave the older ones in the dust. I had a few rolls of standard PETG that I had slowly been using up, but I sold the last 2, I couldn’t bear the waiting times.
I’m going to try a bunch of the new modified materials, like ABS plus and HT, ASA plus, and especially Polymaker’s HT-PLA-GF, a glass fiber high temp PLA that can be annealed in boiling water without deformation to withstand temps like 150º. Nuts! They are basically sold out until August, but once back in stock I’m buying the stuff.
Interesting times to be in the hobby.
So, one thing I did note is that a lot of the PETG vendors these days have been ratcheting up the speed that their normal non-rapid PETG filaments are printable at as well.
For example, Prusament PETG is good up to 200 mm/s and Elegoo’s Pro PETG is good up to 270 mm/s.
These units are somewhat silly IMO. It all comes down to volumetric flow. Big nozzle + thick extrusions + thick layers would probably mean needing to print slower than that speed due to the ability of a hot end to melt the filament.
