Review on 🖨️ Comgrow 3D Printer Filament 1.75mm Spool: Additive Manufacturing Supplies in 3D Printing by Tyrone Carter

Compared to my last filament (eSun PLA+) I found this filament very difficult to use on Ender 3 v2. Now he mostly works, but it was a lot of work to get him to stay in bed at all. Mixing the platform very thoroughly helped a lot, as did reducing the speed of the first layer to auger speed (<25mm/s). With my 0.4mm nozzle, this filament tends to curl tightly around the extruder just before printing, creating a cotton nest of sticky filament that rids the bed of whatever you were hoping to lay down! Using a wide skirt and manually grabbing the clumps with tweezers during the first part of the print solves this problem, but it's annoying. I also found that increasing the flow rate for the first shift helped. The diameter I measured on my reel varies a lot and is also on average much thinner than the nominal diameter: 1.71mm is a typical diameter but it can be lower. 1.69 or up to 1.78. This is well above the 1.75±0.02 in the description and makes flow rate adjustment difficult. This PLA is much less stiff than PLA+. This is to be expected when it is actually pure PLA, but it is something to be aware of. I'm not exactly sure, but I seem to have more stretching issues. This is to be expected from pure PLA as well, but it's worth being aware of. Other reviews suggest that the white is on the weak side. I agree, but as long as you're expecting it, I don't think it should be a bad thing. It's functionally opaque, but with that white filament you get subsurface scattering since it's very (very) slightly transparent. I like the way it looks. I'm new to 3D printing but I've tried a few filaments now and the issues described above with this filament are new to me. I wouldn't recommend it for a beginner. Maybe other nozzles or 3D pens(?) will have better luck. Those issues aside, it's actually fine once you start typing. But I would advise buyers to think about saving a few bucks by spending many hours of your time troubleshooting and printing test towers to pick up on this thread. 🤷
