Nylon Filament PCTPE CoPolymer 1.75mm 3D Printer Consumable, Flexible Polyamide (PA) 1lb Spool, Fits Nearly All FDM 3D Printers (Black)

Taulman3D delivers every single time. This company makes the best filament overall. PCTPE filament is indestructible. It’s not as stiff as nylon but it is not as soft as TPU. If you need something that is rugged and will take a beating without worrying about solvents melting it. This is the stuff to use. However this filament is not for the novice maker. It does take a little time to get dialed in. This filament needs to be in a dry environment for quality prints. I have had good success doing this without having to dry it in an oven. Taulman’s site has great tips on how to print this stuff.

It is a stiff but flexible filament. Do not flex against layer lines, it won’t flex very far without breaking, design your prints to flex with layer lines.The color of this filament is not a true black, it is a very dark blue, this is less obvious in a mildly lit room, however in sunlight it is a navy blue.

It came, Iopened the package, and immediately put it in my dessicant filled Rubbermaid container (holds a single spool on a custom 680zz-based roller assembly). It sat in there for a cople of days before I had a chance to use it. The dessicant was still dark blue, but apparently the filament _really_ soaks up moisture - must have come we from what I can tell. It had bubbles in it, steam puffs would burst out of the nozzle when looked at in operation with a magnifying glass and flashlight. I added a bunch more dessicant (like almost two inches high all across the bottom of the container, let that sit for a day. Same thing. I tried to dry it in the microwave - like I do my dessicant. 20% microwave power, and after about 3 minutes it started making popping noises, and when I looked in on it, there was a big melty blob on one side of the spool - went straight in the garbage. Dunno, maybe I just got a bad spool that was really wet, but it is expensive, and very difficult to make work. If Taulman was to send me more to see if it was a bad spool, I would try it again and see if I can make it work because it is very flexible and I really have a need for something like it, but otherwise, I can't see spending more on trying it again myself. I've used Filamentum Flexfill 96A stuff without issue, but it's not really the same material. I was really hoping this would work. Very disappointed.

After a bit of trial and error I have found a good print setting on my QiDi XPlus3. The nozzle temp is 260c, the bed temp is 60c and the speed is 100mm/sec. At lower temps and faster speeds the prints would be weak and easily break at a layer line or unravel a bit . Now the finished prints are very rugged and fused. Hair spray works for good bed adhesion.

I've tried other taulman nylons, but this one is the strongest one, terrific for functional parts. Prints good on my ender 3 with an all metal hotend. Just be sure to keep the filament dry.

Wasted an evening assuming adhesion issues were due to my printer. I couldn't get the print to stick at 75c bed and with hair spray end tried just about everything in print settings that I could think of last night. Releveled the bed several times and ended up destroying a nozzle in the process. When I removed the nozzle (at temp) I saw a cloud of vapor come out of the extruder which iseemed to ndicate excess moisture in the product.I baked it this afternoon and the adhesion/stringing issues cleared up. The surface of the print isn't as good as I expect on supported surfaces, so I think the temperature profile stated my the manufacturer is incorrect. Most Nylons appear to require more than 242c to print. Still tweaking my print settings to meet my expectations, but probably a reasonable filament at a fair price.

I know nylon is pulled and not extruded, but im sure there are checks after the fact. The roll that I have gotten has such bad bulges in the pull consistantly that I can not even get a 1hr print to finish. I have rolled out half of the spool so far trying to find a contiguious section to try and print with no bulges and no luck yet. Also, this filament is very hydroscopic and does not seem to be pre dryed, and or, not enough desicant is added to the packaging to keep it dry while shipping. I have requested a replacement roll and hope this one has better results, will update this review if so.

This stuff is TOUGH. You will break yourself, trying to break anything you print with it. As far as flexible filaments are concerned, this is on the firm side.It is absolutely essential that you dry this filament before trying to print it. You will fail if you do not dry it first. As long as you do that, this filament will exceed expectations.

I was excited to try this new filament. Was disappointed to find that when the package arrived, it was only a 1lb spool. The description and image both show 1kg. The ad is misleading and had I have known it was only 1lb, I would not have purchased.
