MeltInk3D PHA-1K175NBL05 Neon Blue PLA/PHA 3D Printer Filament Ø 1.75mm, 1Kg (2.2 Lb), MADE in USA, Dimensional Accuracy: ± 0.05mm

I bought this filament in place of my normal go to which is Hatchbox. The filament came well packaged but when I looked at the label it recommended a print temperature of 220C not the 205 which was posted on Amazon. I normally print in the range of 198 - 205. For 220+ I reserve for ABS.I loaded it up and started a print and it failed at 215. Tried again at 220 and it jammed. This time, it blocked the barrier tube completely requiring a complete breakdown of the print head. While doing this, I noticed the drive gear was covered in filament powder. It seems to me that this filament abraides easier than Hatchbox. Of course, this trial of a new filament brand cost me 1 barrier tube and about 2 1/2 hrs of maintenance. Ironically, the spools look similar to MakerGeek which I have absolutely no desire to use again.

This filament is the worst filament I've ever used. I don't know how people are getting good results out of this filament, but i cant even print one good quality piece. My printer stays at its set temperature the entire time, yet the print has very inconsistent extrusions. I measured the filament and it was alternating from 1.8mm to 1.7mm the entire way through the spool. the suggested print temp is 220-230. when printed at 220, the filament is literally like butter! i bought this filament because i really liked the color and was hoping to give it a chance, but now im wishing i never bought it in the first place.

I have both PLA and PLA/PHA from them. The PHA does not print with anywhere near the smoothness. I'd say it's only useful for disposable prints.In the photo, PLA on the left, PLA/PHA on the right.

works great

I would NOT recommend this PLA filament for a couple reasons. First of all, I had to print an adapter ring with another brand of PLA because one side of the MeltInk3d roll (one of the holes) is a different size than the other (see photos). This actually broke one of the spool holders on my Prusa i3 MK2 printers because the holder had to bear almost all the weight of the spool before I printed the adapter ring. I had to print a new right-side spool holder for my printer. Secondly, the filament becomes entangled during printing (see photo), which can ruin the print and potentially damage your printer because the extruder is trying to pull down filament that won't move. When I did get it to print an object, it seemed to be comparable to most other PLA I've worked with, but the issues with the spool and tangles in the filament are a major deal-breaker.

I purchased a spool of the pla/pha filament to try as I heard it was a little stiffer after printing, stronger than regular pla. Well all I can say is…it extruded like warm butter…It’s beautiful…has a nice semi gloss finish and has little to no warp. I’m hooked on it. I’m going to be using alot of Meltink filament in the future.
