Low price PETG, Unsure About Quality

Intro

I bought a spool in August since it’s $25 per KG and goes down with the volume you buy to $21 for 4 at a time. Matterhackers also has free shipping to anywhere in the US making this a good deal for PETG. The spool arrived in a vacuum sealed bag with desiccant inside. The first spool printed great with default Prusa PETG settings. Bed ahesion on a PEI printbed is very good if bed is clean. I ordered 2 more 1kg spools in September and have been having constant issues with material accumlating on the nozzle and then detaching leaving blobs and voids on parts. It’s unclear if the issue is with my printer or the material at this point. It’s unlikely I’ll be able to fully troubleshoot the problem in the near future since Matterhackers is out of stock.

Quality

Diameter measured an averaged of 1.73mm diameter taking multiple measurements with calipers on two different spools. This puts it well within the advertised spec of 1.75 ±0.07mm. No visible impurities were seen. Filament fed nicely off spool.

Print Settings

Prusa Generic PETG Settings 230C Extruder/85C Bed 1st layer, 240C/90C Bed after 1st layer
Matterhackers recommended print settings 230-255C Extruder/55-77C Bed

Availability

Matterhackers seems to have issues keeping their build series PETG in stock. This color has been out of stock for a couple of weeks and is estimated to be out of stock for another month.

Verdict

The pricing is good when buying several at a time, product arrives in a timely manner and product quality may be good (assuming the problem is with my printer). The availibilty issues combined with questions on quality leaves me looking for another source for PETG.
