I printed some black PETG HF supposed to be Matte, this came out very shiny!
H2S AMS HT Bambu settings 0.4 nozzle.Dried 8 Hours @ 65 C
Thoughts?
There is no Matte from BL in PETG. Usually temp will affect the finish. I can’t remember which, hotter = glossy and cooler = less, but it could be reversed.
If you specifically bought Matte PETG check the temp and other settings for the filament.
Yea but I have heard it was less glossy than regular PETG and was wondering, Maybe Ill try to adjust temp
I did buy some Sunlu Matte PETG High Speed, it is less glossy but a pain to print.
Also the refills look exactly like Bambu’s notch and straps the same too.
Thanks
What profile are you using? Is the filament dry? I can say my BL PETG-HF isn’t nearly as glossy.
Did you use the recommended settings for it? Did you try a test print with either the BL PETG (old) or the Sunlu PETG, or the Generic? Was that filament dry?
Yep, you can use Sunlu Refills in BL spools, or those printed to hold BL filament.
I was aware of that , but makes me wonder if its made by the same company and/or if it is the same filament.
The insert and bands are exactly the same, not just fit
Again, it’s been considered.
Anycubic cores are nearly the same too. I would imagine that Sunlu/Anycubic considered that the norm so BL users could buy refills as well. I have,
Whether they are the same is anyone’s guess. This has been explored for at least a year if not more. I’m of the mindset they aren’t. That’s just me. I’ve seen differences in each.
Never had Bambu Lab PETG HF in black, but white and gray. They’re matte. When I was forced to use Sunlu Black PETG, due to no HF in stock at Bambu, I noticed a gloss similar to yours. Please keep in mind I used HF White and Gray > no gloss at all.
Sunlu has PETG and HS PETG Matte, I have the Matte, it was so cheap I had to try.
It didn’t print so well at first it was matte but bad prints, until I lowered the temp as John said to 230 then it does well
I think a keeper
See above. Used Sunlus “normal” PETG in black. Photos show a colo(u)r I haven’t used so far, it’s the same type.
Results:
Compared to Bambu Lab PETG HF which is more matte > Sunlu PETG is glossy.
Edit: Sunlu works just fine with Bambu PETG HF profile IMO.
I guess it is related to the chemicals used by Bambu to achieve high flow rate.
PETG was in general a touch more shiny/glossy and had in the early days no colo(u)r, just it’s natural look. At least when I started my journey in 2010/2011 with RepRap (the replicating rapid prototyper). Dr. Adrian Bowyer, my personal hero 
.
This is the filament I have, I needed to drop temp to 230, works great now, for the $ I think I will be buying more, the Bambu does print a little better. Will see how other colors do, they have a multi color refill pack.

No way to get such a glossy print with BBL PETG HF, no matter the settings or humidity.
When filament is not properly melting, e.g. printed too fast or too cold, it will become matte and considerably loose strength. It is basically a defective print. There is no mechanism that makes matte filament glossy that I know of.
I think you should re-read what’s I’ve written. No where did I say it’s matte.
As well as I’ve mentioned my PETG HF aren’t nearly as glossy as the example given.
