OVERTURE Nylon Filament 1.75mm 3D Printer Filament, Polyamide (PA) 1kg Spool (2.2lbs), Dimensional Accuracy +/- 0.02 mm, Fit Most FDM Printer (Black)

I like Overture anyway, so I'm biased a little. They're not my #1 but I will use them when the price is right or my prime filament (eSun) is out of stock. I got a project request from a customer that needed a small nylon part. Woohoo! I've never printed in nylon before, only ever used PLA and dabbled in PETG. Honestly, I was a bit scared of it! This was my big chance.I started reading up and all the sites said I needed an enclosure to maintain heat or the print would warp. Ug. I have a CR-10 Max (it's huge) and the cheapest ready-made enclosure available is $700. Even building a hack-job enclosure myself was going to cost at least $100 and several trips to Home Depot, which is hard to justify for one lousy, rather small print job.Another site said I needed to vent to the outdoors. There's another $50. And, I was looking at a few nights and weekends to put it all together. Yes, then I could print Nylon whenever I wanted and ABS and blah, blah. I just don't have the energy for it right now. (I'm old.)Yet another site said I should get some Magigoo (which I did order but it hasn't arrived yet) to get bed adhesion. Well, that's another $30 at least.Give me a break!!!It turned out that I didn't need any of that when printing with OVERTURE Easy Nylon Filament. For some reason, the product title doesn't say 'Easy' (it's written on the spool) but it should! That's a great way to describe this experience. It was easy. Almost PLA easy and much easier than I ever expected.I decided to just try it without all that just to see what would happen. I decided to treat it like PLA and see how things came out. The only thing I did differently than PLA is ventilation in the room and temps. I know there would be fumes - we are melting plastic after all - so I opened a window and propped a fan in it. I turned on the central AC fan only to create some positive pressure in the room and I stuffed some towels under the door. I have pets and kids so I don't want the fumes in my house. I have a HEPA filter so I cranked that up to high. And...that's about it.I was concerned that the ventilation would cool the nylon off too much and it would warp but it didn't seem to matter.Here are the settings I used:50º C bed. I'm using a Wham Bam Pex flexible bed which is rated for Nylon. I already had this.250º C hot end. I use a Micro Swiss all-metal hot end with a .4mm hardened nozzle.First layer 104% width6mm retraction at 30mm/s since I'm using a Bowden tube.A skirt but offset (not touching) the objectNo part cooling. Set the fan to 0%.Printed at 50mm/sNote that these are all the same settings (except hot end temp) that I use with PLA+.That's right, this filament prints more or less like PLA!!!!! And, my print was all but perfect. A tiny string coming off of one corner. Which, if you know 3D printing, that IS a perfect print. Anything less than 1 minute of cleanup is perfect in my book and this was literally 5 seconds of cleanup.Who are these wizards at OVERTURE and why isn't all nylon like this?OK, let's talk about smell. It does smell, even in a vented room. It's not terrible - I'm sitting in the room as I type this - but I'd say you probably don't want to be around it. It's a warm plastic smell, as one might expect. I don't know if it lingers after the print is done. I'll update this review if it does but I assume it won't. The price was excellent. Less than $30 for a kilo spool. I'm tempted to buy another one because I know they'll increase the price when it gets popular. And, I'm betting it will get popular as soon as more reviews come in. When I bought it, there were no reviews or ratings so it was a bit of a chance...Let's add this up. Let's say $30 for the spool. -$150 for an enclosure I didn't need. -$50 for a vent I didn't need. -$1000 for the time saved not setting up said enclosure and vent. All told, this magic filament saved me $1170 (or $170 if you don't count the labor). If I had chosen any other nylon, I'll be I would have had to spend every penny of that. This is real savings. [edit: I forgot to credit in the cost of the Magigoo which I didn’t need.]I said at the outset that Overture wasn't my #1. I'm thinking really hard about changing my mind. I'll say this, for Nylon I will not buy any other brand unless I absolutely have to. This has been a fun weekend!

Necessities: Filament dryer, PVA Glue (glue stick or elmers school glue), enclosure (for larger flat parts especially with sharp corners on the bed)Things to know: Does seem to ever so slightly shrink a bit (<1-2%) the further you get from the bed, I did notice one of my long rectangular parts had a slight taper to it as it got further from the heated bed. Wasn't worth doing anything about in my instance, but it would have to be accounted for in the design. I don't know of any slicer settings that would compensate the size of the part several millimeters of Z-height into the print.Printed well on a nearly bone stock MK3S. I am running a 0.6mm Bondtech CHT, which does put more heat into the filament, so you may want to run 5-10C cooler on the hotend temps. I modified the Ultrafuse PA profile a bit to have a starting point. Just threw some gluestick down on the bed and stuck my small Creality dryer in a simple foam mat square enclosure to prevent warping, I did try printing without an enclosure and it did come out warped the first go around. They say not to use a print fan, but I did turn mine on to prevent some overhangs that were curling. Dried it for 8 hours at 50C and it printed well right from the dryer. Zero stringing whatsoever. Color seems to be a nice true black, some other filaments I've printed have a green tint to them. I paid $32/kg for it and its still a decent deal at $37. Seems to have good mechanical properties, time will tell. I mostly print Overture PETG (my go-to filament). Seems pretty similar in mechanical characteristics. Changing your top and bottom infill pattern to Hilbert's curve also seemed to help. Only thing I might do is turn the fan up a bit more, it still ever so slightly curled on one overhang. Overall good experience with nylon and will be using it for more projects in the future.
