ACTIVEME PETG+ Filament 1.75mm, 3D Printing Filament for 3D Printers, PETG+ 3D Printer Filament, Dimensional Accuracy +/- 0.02 mm (1kg Red)

This is the best transparent filament I've tried yet out of 3 different brands. You can print glass-like parts under the right conditions, though they will always have a lenticular effect on the surface, so be realistic about your expectations. Compared to Activeme PETG+, CC3D PETG has a slightly foggy appearance. Polymaker PolySmooth PVB performs similar to this ACTIVEME PETG+ in vase mode, making a nice, clear print, but as it's a soluble filament, I haven't actually tried printing it outside of vase mode yet. Some use PolySmooth PVB as a dissolvable support, some use it because you can "polish" it with isopropyl alcohol, which can be tricky to get right (there are videos out there on how to do that).There is a brief tutorial on Printables titled "how to print glass." The key to glass-like prints with any filament, as another reviewer also described, is to print with 100% infill using aligned rectilinear infill so that all paths go parallel in the same direction. Minimizing or eliminating walls may help, depending on the dimensions of your object. Print on a smooth bed, preferably glass. With the Activeme, I found that a bed temp of 50°, and a print temp of 220°-240° to work best, though you should print several tests to dial it in to whatever works for you. Try a layer height of anywhere between 0.1mm-0.3mm. Print between 20-30mm/s with no part cooling. The goal is to have the material fuse into one piece with a minimum of trapped air bubbles. Imagine you're going to make a transparent cube out of silicone caulk- you want to go slow and steady, line by line, layer by layer, letting the beads of silicone touch each other and seep together, without trapping any air in between them or allowing the surface to dry before you're done.Having dry filament is critical. Anyone with enough experience will know that's often the last think you think of, and the thing which does the trick with whatever problem you're having. Moisture in your filament will manifest itself here as lots of small or microscopic bubbles, fogging up any translucency you might've achieved. If you don't have a filament drier, you may be able to place your spool on a sheet of paper on the bed of your printer, set the bed temp to 70°, and place a cardboard box just big enough to cover your spool. Let this sit on your heated bed for 4 hours, and it's pretty much guaranteed to dry your filament quite well. Just make sure to check it regularly to ensure your filament isn't softening and fusing together on the spool, that your spool isn't sticking to the bed, and that you don't have any unfortunate malfunctions. Newer printers generally have good thermal runaway prrtection, but you should not leave your printer unattended anyway.That's pretty much it. Activeme PETG+ is so good that even though I still have 2 full spools of other brands, I've run out of the Activeme and bought another spool to have on hand.

I am printing parts for a MK3s+ Bear Version 3D printer and 90% of the parts are printed from PETG. I decided that this bright green would be my machine's base color. While searching here on Amazon, I found this spool and decided to buy a roll and give it a try. Came nicely packaged in a sturdy box, vacuum sealed bag with desiccant. don't be a bonehead like me! Open the top of the bag and it will zip closed. Or be like me and open the bottom of the bag first and then notice the zip lock. Either way works but only one way works better. I'll let you figure out which is which.. For a test print, I printed a replacement fan shroud for the printer. As you can see, the original is a little bit worn. This part should be made of something that can handle a little higher temperature but even if it only lasts for a couple of prints, it will probably be better than that sad little original part. The filament was rolled pretty well and printed fine with the stock Prusament PETG profile. No supports were needed and the final results were very nice. Now I only need to decide if I really am going to do the Bear or if I want to try out the Voron!

The media could not be loaded. Not the best PETG+, but it prints well. Far less stringing than normal PETG, and the smaller roll is nice. The filament on the spool is not wound particularly well, and the anchor for the end of the filament can get stuck on the spool holder. Also, the initial layer is a bit difficult to lay down, but bumping the temp way up seems to help. But again, it's less than $10 a roll. Id say it's worth it.I'm printing around 200mm/s at 250c/90c with a knockoff volcano CHT nozzle. Id ignore the recommended temps on the packaging if you'd like to avoid jams or clogs.If you can get this stuff at or around $10/spool, 100% would recommend.

So I've never printed with PETG before so this is my first go around. I wanted to do some testing for some things I wanted to print.So let's start with the packaging. First, it was nicely shrink wrapped and included a silica packet that was taped inside the spool. The spool itself is made out of cardboard but overall the whole spool felt heavier then I'm used to with PLA or PLA+. All in all, a very good first impression.So now to printing. I'm using an Ender 3 Pro with a .6mm nozzle. Hot end is 220, bed is 50 and I use masking tape over a glass creality bed. The file I used was sliced with Pruscaslicer 2.6.3 alpha using .28mm layer height. First layer went down without any issue and as you can see the results of the print in the image.Final thoughts: Very good first impression. Quality of seems apparent in the material as I spot checked the thickness with a micrometer and it was within the tolerance limit. I liked the cardboard spool for recycling but the spool itself was thick and hearty enough for the filament. I'm going to make some more prints with this as I like that it comes out semitransparent. As long as everything looks good, this brand will be my go to for PETG as I'd like do more with the material.TLDR; Would buy it again as it seems to be a good product.
