Polymaker PA612-CF Nylon Filament 1.75 Black, 500g Carbon Fiber Nylon Filament 1.75mm - PolyMide PA612-CF Strong & Low Moisture Sensitive Nylon 3D Printer Filament

It Takes a 'LOT" to impress me and the Plastic Polymaker PA 612 really gets it together!.Now Nylon is One of the Hardest Things to print right, But its also rewarding as if done right it makes some of the hardest parts ever!...Its an Exceptional Filament and for real as it can take real punishment, But its fairly easy to print and makes some good parts without exception!.In short its a specialty plastic as frankly not everyone needs a Workpiece super hard , And its a Higher priced Item tho there are others more costly!.But out of like 30 differing and yes costly plastic from different firms only 3 outa some 30 odd plastics pass the Supreme Test which is where i just simply jump up and down on the finished part and it 'DONT' break!.Seriously This Is Some Really Good stuff as I'm 165 and I cant just break it, So this stuff its that good!.PLUSES:It is really Super Hard stuff!.It has a slight flexibility so its not 'Too Likely' to just crack or fall apart!.Unless you go crazy with Heat its not real great on warping!...It may not be right for all applications, Like Marine use as Nylons will absorb Water but for Parts!.,..MINUSES:Its Good Even Excellent but its costly tho It will meet a need!.It like other 'Hard Plastics' It can be can be hard, To dial in but its workable!...Like any other Tool it depends on your Skill level, Plus your willingness to Adapt!.Now my first Test Part was junk! My Second was passable, But i still needed Help then i remembered a Tip from an earlier reviewer that at times if you 'Cant' get something dialed in you can use CURA profiles to find a workable answer.OK I tried several but the one that seemed to work best with My Printer an Ender 3max was:Emotion Tech Nylon 1070!.The Basics seemed close enough to work as i only changed a couple of factors but here are the Specifics!.SPEED 45Heat Start at 261, then afterthe 1st layer run the part at 258!BED Start at 65!After the 1st layer drop to 50 or 55!...Speed is what works best for your Machine tho im doing well at!SPEED 40 to 45!.....I heat dry my plastic, and let my Printer warm up on ABM settings for about a half hour!.And run the Filament in straight and hot from the dryer and im getting some nice parts!.Its a Great Plastic once you learn to use it!.....Hope this Helps!IndianaED.....

I thought it printed quite easily compared to CarbonX HTN-CF. Less nozzle drip at similar temps and it is more responsive to processing temperatures when tuning for strength or toughness at desired layers. Works well as a break off support material when processed at higher temperatures due to degradation driven embrittlement. Very versatile filament.

Tried the pa612 and liked it great layer lines strength etc I've tried other brand pa6 and it doesn't hold a light to the polymaker pa6, this stuff prints amazing layer lines are almost non existent, extremely strong and rigid (sounds like aluminum) fantastic layer adhesion, printed at 295c nozzle and 40c bed with .5mm tungsten carbide nozzle 50mms .15 layer hight next purchase will be the 2kg spool, 100% worth every penny

Wonderful stuff, no complaints at all.Very strong and makes for a great material for printing your own 2A lower frames. Close to the original material used by firearms manufacturers.

Ender 3 all metal hotend. 272c /50c 25mms .6 nozzle. glass bed. You must dry and print from a dryer 70c. dried in oven at 90c for hour then over night at 70c. copper nozzle that is plated.
