Review on Comgrow Filament Drying Box With Filament Holder And 2 PLA Spools, 1.75Mm Diameter, 1Kg Capacity Per Spool - Ideal For 3D Printing Filament Storage And Protection by James Mayberry

Compared to my last filament (eSun PLA+) I found this filament is super difficult to use on an Ender 3 v2.I have it mostly working now, but it was a lot of work getting it to even stick to the bed. Retramming the bed very carefully helped a lot, as did reducing the speed of first layer to a snails pace (<25 mm/s).On my 0.4mm nozzle, this filament tends to curl up tightly around the extruder just before print, creating a wadded nest of sticky filament that scrubs the bed clean of anything you were hoping to lay down! Using a generous skirt and manually snatching wads with tweezers during first part of print solves this, but it’s annoying. I also found increasing the flow rate for the first layer helped.The diameter I measured on my roll fluctuates a fair bit, and also averages a lot thinner than the rated diameter: 1.71mm is a typical diameter, but it can be as low as 1.69 or as high as 1.78. This is well outside the 1.75 ±0.02 in the description and makes it difficult to dial in flow rate.This PLA is much less rigid than PLA+. This is expected if it’s a truly pure PLA, but something to be aware of.I can’t be totally sure, but I seem to be having more problems with stringing, too. This is also to be expected with pure PLA, but worth being aware of.Other reviews have pointed out that the white color is quite weak. I agree but, as long as you’re expecting it, I don’t think that has to be a bad thing. Functionally, it’s opaque, but you will get subsurface scattering with this white filament, as it’s very (very) slightly translucent. I like the look of it.I’m pretty new to 3D printing, but I’ve tried a few filaments now, and the above problems with this filament are new to me. I wouldn’t recommend this to a beginner. Perhaps different nozzles, or 3D pens (?) would have more luck.Other than these issues, it actually is totally fine once you get printing. But I’d counsel shoppers to consider whether saving a few dollars on a roll is worth the many hours of your time troubleshooting and printing test towers dialing in this filament. 🤷
