Fantastic Quality PETG for Functional Prints! 💯
I use PETG constantly for making all sorts of functional parts, and this SUNLU filament is consistently top-tier.I bought the red, and the color is incredibly vivid and rich. The print quality was great—I had solid performance across a good temperature range, excellent layer adhesion, and, critically, no nozzle clogging whatsoever. My functional parts came out strong and durable.I’m a heavy user and buy tons of this brand. Zero complaints. Highly recommended.

Very surprised at the quality; highly recommend
I’ll start by saying I had extremely low expectations for this filament. I print exclusively in PETG, and lately, Bambu Lab PETG HF has been my go to option. It prints extremely well and isn’t hard to achieve great results. ELEGOO Rapid PETG is okay, but it’s nowhere near as good as Bambu Lab. I have just been using it as it is the cheaper option when bought in bulk.Then, I came across this High Speed PETG from SUNLU. I really like the matte look of Bambu Lab PETG HF, and it appeared SUNLU would be a closer match than ELEGOO, which is far too shiny for me. I bought the 2 pack in black. Ran a test print without drying and then after drying. There was a noticeable difference, but it wasn’t bad straight out of the packaging. All of that was on the profile for Bambu Lab PETG HF. When I changed it to the Generic PETG HF profile, things got even better. See photo.I’m now disappointed that I put in an order for four more spools of Bambu PETG HF just before buying this filament. Once I use that up, I will only use SUNLU High Speed PETG for black and white. The pricing for the other colors is a little too much still, and my one real gripe is that they do not have a light gray. That is the color I use the most. If SUNLU carried that and sold it in bulk, I probably wouldn’t have to rely on Bambu Lab for any more filament.

Final Verdict: HARD PASS white petg
Sunlu’s White PETG is easily one of the worst PETG spools I’ve ever had the misfortune of loading. It behaves like the pigment was ground at a gravel quarry and then tossed into molten plastic as an afterthought.Here are the highlights of this disaster in filament form:• Ridiculously hard to melt properlyEvery other brand melts normally.This one?You basically have to run it at ABS temperatures (260–265°C) just to get it to stop printing like thick toothpaste.• Coarse pigment = toothy, serrated extrusionLines come out looking like someone dragged a serrated knife along the leading edge.Small circles print fine, because the filament only misbehaves on long, straight geometry, meaning the pigment turbulence is the real culprit.• Temperature-sensitive to the point of comedyAt 255°C it under-extrudes.At 265°C it finally melts……but then shows random glossy/matte discoloration based purely on geometry.The same shapes in the same areas create the same color shifts every time.• Flow tuning nightmareNormal PETG behaves around 95–100% flow.This spool?0.98 was under-extruding.1.02 caused ripples from over-spread on layer one.You basically have a window of about 1% where it behaves.That is NOT normal filament behavior.• Boogers — the silent killersRandom micro-snots appear at the most inconvenient moments, especially when the melt hasn’t completely heat-soaked.I lost multiple prints because of this nonsense.• Chalky, gummy purge linesCompared to Overture PETG, the purge string feels rough, gritty, and inconsistent.Even the purge line tells you this filament isn’t right.• Inconsistent surface finishThe first layer can look matte, glossy, rippled, or completely fine depending on:geometryspeedmomentary melt behaviorcosmic alignmentluckThis is NOT how PETG should behave.• Better brands exist for the same priceOverture, Polymaker, Elegoo, Prusament PETG. all of them melt consistently, produce stable lines, and don’t turn print tuning into a multi-hour spiritual journey.Unless you enjoy spending hours recalibrating:temperatureflowfirst-layer squishbed temppressure advancenozzle wipingfan curves…just don’t.Sunlu’s white PETG behaves NOTHING like their other colors and requires way too much tuning for mediocre results.This spool goes straight into the “never again” category.Save yourself the headache. Buy literally anything else.

My go to PETG
This is my go to PETG – Not matte by any means, but less shiny than regular PETG. Prints well at super high speed as long as you crank up the nozzle temp. On my 5th roll with no failures.

Moeilijk te printen
