3D printing with my first spool of Elegoo Rapid PETG ( https://au.elegoo.com/products/rapid-petg-filament-1-75mm-colored-1kg ) bought at Jaycar , looking very clean and sharp on a slow speed profile

I should recalibrate my Overture PETG ( https://overture3d.com/products/overture-petg ) now that I've figured out the speed issues on my printer

Elegoo petg and PLA have become my go-to over the past 2 years. Rapid vs pro tend to affect me more with how brittle the end product is than printing speed. I'm using a K2 Plus, but also printed on Anker M5C.

Fun detail: you can order 10kg packs for a good discount vs other shops if you hit their site directly.

My only gripe is they don't have variety packs of their fancier stuff. Some of their silk is gorgeous.

I usually have gotten about 35-40% rh on my should out of the bag. I still get good quality at that level, but would warn to actively dry a bit if you are in a more humid area for sure.

I had no issues with any brands I've tried so far (PLA or PETG): Creality, Elegoo, Polymaker, Sunlu.
That's also true for even some obscure brands I've tried because I paid only $6/kg for them in a discount local store: Ziro, Do3D, iBOSS

Tbf, I had problems with exactly one brand repeatedly: eSun Of all the brands the one most people consider a safe bet gave me the most hazzle.

I absolutly used cheap brands as well and had no/less isues than with them.

Currenly heavily using Sunlu/Jayo (same brand) for PLA, extrudr , formfutura and black forest filaments for ASA, extrudr for the remaining technical stuff. Whatever's cheapest for PETG.

It works pretty well for me. It prints fast, it's strong and has good layer adhesion. It does take quite a while to dry a new roll though. The cardboard spool holds a lot of water.

It was under 50% relative humidity in my garage today, so I just put the spool right on the printer and hit "go" :)

Over 50% and I usually run active filament from a dry box to the printer

I haven't gone to the trouble of pre-drying a spool yet

[–] cmnybo@discuss.tchncs.de 4 points 3 days ago

It's too humid around here for that, especially this time of year. I have to keep mine in a sealed box with desiccant. Putting a new spool in the box without drying it just uses up the desiccant quickly.

At least PETG doesn't get brittle like PLA when it's wet. It just gets stringy.
