3DXTECH 3DXSTAT ESD PLA 1.75mm 750g 3D Printing Filament

The filament was good, but the subpar spooling caused underextrusion on a whole layer throughout my pring, (as shown with top and bottom sections). For $92 / 750 g, I would expect a much better spool!Be sure to thoroughly dry the filament as well. Moisture content seems to inhibit layer bonding when printing.

Fresh out of the bag, the filament would break even if simply straightened out. It proved impossible to use. Waste of money and material.

Excellent print quality, meets ESD requirements. Print several spools of this per week for test fixtures. Biggest problem was poor spooling. Very brittle filament. Spooling combined with brittleness was bad enough where filament actual snapped on several longer prints (10h+) leading to print failures. At the cost of this filament failed prints become expensive, especially considering how simple the issue is (spooling quality).

I've tossed out several half reels of this as it is the most brittle filament I have ever used.We get it at my job to make test fixture and other items. Lately I can hardly get a print to finish even using a freshly open spool.If this wasn't the only game in town for ESD PLA...

The good:I tested the conductivity of a portion of filament before printing. It is very low, but should be sufficient to dissipate ESD. With 15V across about a cm of filament, I was able to measure 5-10 nano-amps using a very sensitive ammeter. Standard PLA did not allow any current to pass at those levels. I am comfortable calling my final print "ESD safe".It prints fine on my Ender 3. I did bump the print temperature up by 20C from where I normally run PLA. 3DXTECH recommends 190-220C for regular PLA, 210-240C for ESD PLA. I normally print generic PLA at 210C, so I started with 230C for this stuff. All other settings remained the same as usual.The bad:It is wrapped poorly. So far no tangles have been too tight for my extruder to overcome, but print quality may suffer. I'm glad that I do not require perfect prints. For the price paid, this is not good. I hope that their quality can be improved. I will look harder for a different brand when this spool runs out.In addition, the outer circumference of the spool is not smooth. It lurched dangerously in my filament dryer, which relies on rollers for that outer edge. I had to switch to a pipe through the center.

We have purchased dozens of ESD PLA from 3DXTECH and works great for our electrical components, fixtures for PCB Boards, or anything that needs ESD Safe prints. Yes the filament roll is not as tidy as other filaments but for the 5 months of printing with this material, I've only a handful of times where I've had to pause a print to untangle the roll. Most times it's print and go.Would highly recommend this filament if you need ESD-safe filament.
