HATCHBOX PA Nylon 3D Printer Filament, Dimensional Accuracy +/- 0.05 mm, 1 kg Spool, 1.75 mm, White

Let me first say that I have used many Hatchbox spools of 3D filament, most of which have been in PLA, ABS, and PETG. That was one of the reasons I purchased this particular product to begin with, I've traditionally had huge success with their filaments and getting good results.My printer is a Prusa MK3 MMU 2.0 for reference with several hundred hours of printing in PLA, ABS, PETG, and some proprietaries like wood, metal, etc.I purchased this particular product because I am printing a part that is rather large taking up almost the entire bed and needs to be both accurate and handle wear and tear as it is a mechanical part. After several issues with PLA and PETG warping just enough to cause problems, I decided to purchase this PA as it was recommended as a lesser warp filament.Product arrived just fine, typical Hatchbox packaging, however, I ran into an issue right away in that the box and the website description give two different setting recommendations, so I ended up trying both (and quite a few others). That's where it falls apart...literally. So far with all the settings set from both the box and from the website description I cannot get this filament to pass the first layer print test that is built in on the Prusa. This test for those of you who do not have a Prusa prints a very fine line of filament in a back and forth motion across the bed like it was navigating a city street to get somewhere. At the end it flips over to a back and forth touching pattern that leaves you with a "flag" of filament that is supposed to be consistent, sharp edges, and stick together and not pull apart. This test is really for adjusting the Z access to get the best consistency when changing spools and/or media so that the printer prints well. I have not been able to get past this test. When I print and using WIDE ranges of z-axis settings to make the layer thicker and thinner, I am getting literal bubbles/spittle coming out, almost like it's too hot...or maybe not enough? This in turn means that the line it's printing is more like dashes and is absolutely horrible from a testing perspective. Keep in mind, I have somewhere around 20 other spools of various materials in many other vendors, types, ages, etc. All kept in dry, nice conditions for printing. This one is fresh out of the bag so I'm pretty sure it's not moisture. I've tried various temperatures on both the extruder and the bed to no success.I'm not giving up on this yet, however, I have a strong feeling this is a rather new product and if they would just make the instructions more clear maybe there is an aha in there that will make this work well. if so, I'll modify my score, however, as it is, it's a 2 star filament to me.

Bought this filament as I wanted to print some more durable items on my Qidi X-One2. The X-One has a max print temp of 250c so I'm limited on the materials I can print. So far so good, I've done one test print and am currently printing some parts I needed. I originally planned to print some gears but this nylon feels a little soft/flexible. It is also pretty easy to cut with a razor blade. Fortunately, I have some other parts that need the fixability. No warping or adhesion issues at all but I’ve only gone up to 12mm high. There is a small amount of shrinkage compared to PLA. First print was strait out of the sealed bag with no dehumidifying. I’m storing the filament in a sealed container with desiccantPrint setup:X-one2 with Micro Swiss MK10 All Metal hotendHotend temp: 210Bed Temp: 1st layer 90c then 75cFan: OffRetraction .3mmLayer height: .1mmSpeed 50mm/s

Well, was hoping for something better than ABS, but this isn't it. So far I've printed at 240 & 270C and still the bond line will break apart with minimal force, not even close to ABS strong. Granted at 270 it was better, but nothing like nylon would react to mechanical stress. Between filament strand bond line was weaker as it got taller. Running tension along the length of the filament was much stronger as expected. Who knows what the magic number is for this stuff. I suppose if they sent me a free roll to figure it out, I probably would invest the time. Ran on a Qidi X-Pro with tech support from Judy...who is A+ in my book

Using an Anet A8 with E3d Titan Aero this filament is just a pleasure to work with. At a .1 layer height I have printed a few structural components and gears and have experienced no significant warping with a very beautiful part. I did build a full dry box before opening the Nylon and using it so it has had nearly no interaction with humidity.Edit: Came to downgrade my review, This filament is nice, but I am seriously confused as to of if it's actually nylon? I say this because AS stated I printed some structural parts from it and they seemed to be nice at first, but they started warping and at a lower temp than my PLA part it replaced. I printed the E3d Titan Aero carriage out of this and it gave out after a week. Wtf is wrong with this nylon? Its more like flexible melty PLA.If you want some cool feeling and looking black parts this is still a great filament, If you are looking for nylon for its properties you may want to stay away.

I have had great luck with HatchBox PETG so I though I would give their PA a shot. I needed something a little less rigged but still had relatively good thermal properties. This filiment does print well. However this does not have the thermal properties you would expect from a PA due to the low print temp. The nozzle print temp is around 200 degrees. I did not realize this when I purchased it. I requested a data sheet from HatchBox to see exactly what the GTT is. Unfortunately their responds was "At this time we are unable to provide the Material Properties sheet for our filament". Not the answer I was expecting. You sell a product but don't provide the spec sheet for it?? So to tested the thermal properties by placing four printed parts in a 170F oven and brought them up to temp. One HB petg, HB pla, eSun PA, and this. This product was very soft and pliable. Worse then the pla. Not what I would expect from a PA. It does print well. But I would not use this in applications where the temp might be higher then where you would use a pla product. I'd be nice to see the true specs of this product.

Package came vacuum sealed to keep clean and dry. I chose this filament after reading somewhere hatchbox has high quality filament. I haven't yet printed with it, but i can't wait to. I have specific projects i want to use them for but my computer's ram is out on rma. When i get the ram back i will be sure to upload photos!
