HATCHBOX Magic Stone PLA 3D Printer Filament, Dimensional Accuracy +/- 0.03 mm, 1 kg Spool, 1.75 mm, Gray

Aside from the price jumping almost 20% in 2 weeks, this is fantastic filament.It prints clean and based on my temp tower, seems just fine anywhere in the 205 - 215 degree range. It does seem to leave a slight residue when peeled off the print bed. I found I had to clean the bed after every print with this filament because it wouldn't stick properly on a subsequent print.

It's interesting stuff, has a rough exterior and matte finish. It is more brittle than regular PLA and the layer to layer adhesion is a bit poor at 215C (bumped to 220). It also doesn't hold as much detail.I was printing this as part of my lighted dice lamps and the top and bottom piece have a friction fit, the tines on the bottom can't be used as designed with this material as they break when fitting. And one of the parts I printed at 215 sheared at the friction fit when using a standard pla base. Increasing the temp to 220 has helped the layer adhesion so far, but I think I'll relegate this material for designs without specific mechanical constraints.

Don't buy this filament unless you really need something to look like stone. I was able to get one successful print, and to be fair it looked great. Had all the same properties as PLA, but it's just extremely brittle. After only a few days out of its vacuum bag, my extruder motor refused to push any filament through if there was even a tiny amount of tension on the filament strand. The gears would grind the filament down and wouldn't push through anymore. On the off chance that the filament made it all the way to the nozzle, then during some jerky movements, the filament would snap and cause issues for the entire print. I've left a roll of regular PLA out for months and it was able to print just as fine as it had before, but whatever they did for this specific filament makes it a nightmare to print with, so I'll be trashing it with .99kg still left on the spool.

I tried repeatedly to use this filament, but it kept clogging the nozzle immediately, not even getting through an initial nozzle swipe before clogging. I kept clearing the clog and retrying until it eventually rendered the nozzle unusable and I had to replace the nozzle. It's also extremely brittle, breaking 3 times when trying to load into the bowden tube. Hatchbox support said that it sounds like the filament was damaged en route or something. Basically, this was completely unusable, damaged a nozzle, and breaks very easily. I was never able to complete a nozzle swipe, let alone a skirt, brim, raft, or actual print with it.

I've seen where others print this filament within the expected temperature range on the roll (180-210˚C), but I haven't changed it from Prusa's default settings (for their own filament, "Prusament", which is set at 215˚C nozzle and 60˚C bed) and i've gone through 3kg now printing just fine. Best thing to do, like with any new filament, is print a calibration test to see how your environment affects the filament's ideal parameters. I can only compare this filament to Prusament, but I find this filament to be just as reliable and as good of quality as prusament, and at a cheaper price.

Used a spool of this on two different printers in our printer farm, and whatever the additive is that makes this stuff look more like stone did a number on both of the hotends.The prints came out fine. We switched spools on both of the printers to a standard PLA for our next prints and both printers started air printing at almost exactly the same time, about 33% of the way through the job. The hotends were badly clogged. We were able to clear one with the usual tools in a nozzle cleaning kit, but the other? A new hotend was the only answer. The particle deposits inside the hotend were so bad that a cleaning kit, hot pulls, cold pulls, using cleaning filament... everything failed to clear it.It sounds like some people have had real success with this "Magic Stone" material, so maybe I just got a particularly grainy spool. I'm not willing to try another to find out. All I can say is use this stuff at your own risk.

Goes from 1.75mm down to 1.65mm in just a half meter or so. Makes prints have really bad lines. If this were to spec it wouldn't be any smaller than 1.72mm. Measured with calipers after crappy prints. Really surprised because hatchbox is usually pretty good.

I really like the color and look of prints with this filament. The only reason I give this 4 stars and not 5, is because my printer nozzle jammed for the first time in a year with my first print. I set it on the shelf for a while but decided to give it another try. I'm glad I did because this time no jamming. There are actually little specs in the filament that give it that brick or stone look. I'm guessing that one was just a little big for a 0.4 nozzle. But after the first jam, I have printed over 6 or 7 hours with it and no problems.

Most of the roll of this magic stone PLA that I got was going good. Everything was printing good and went to bed. I woke up with my printer printing in mid air, wondering wtf. Found out that the filament snapped in the boden tube. I was breaking pieces of filament off the roll. I will never use this stuff again and is going in the garbage. I have other rolls of Hatchbox pla filament and hoping they aren't as brittle as this stuff. I am using non-hatchbox pla for the rest of my print.Hatchbox is supposed to be premium filament. So far not impressed.

El filamento no tiene buena adhesión al menos no en mi cama de vidrio, también no se combinan bien las capas, lo que provoca que la última capa quedé mal. También después de unas 10 impresiones se provocó un atasco que me obligó a cambiar el nozzle

El embalaje es bueno, la entrega para prime excelente. La calidad del filamento es buena par este tipo mármol.(aunque compre otro color blanco el cual salió malísimo)

Is good had some minor stringing on one print which might have been my settigs but satisfied with it so far that I am going to try and stick with it.

Quede muy satisfecho con el filamento, no batalle para imprimirlo y dejo un muy buen acabado
