Review on 🔧 Enhance Your Additive Manufacturing with Polymaker PolyMide Samples: Reinforced Filament for Exceptional Results by Andrew Grant

This is a review I am writing in shock. First of all the delivery was fast, Revain and the seller were on it. I'm a big fan of Polymaker, from Polylite PLA and PCMax to Polymide CoPA. So far I have only ever been satisfied with Polymaker. After going through 4 spools of MatterHacker's NylonX without a single usable part, their support team gave up and said their product just couldn't make the airplane parts I make. I was looking for something durable, heat resistant, and not as horrible as NylonX. I found Polymide CoPA and this stuff is amazing. No warping at all, durable and prints like butter. It doesn't have the stiffness of NylonX though, so I had high hopes for PA6-CF, and it comes in larger spools than just the tiny 750 CoPA (each of my pieces weighs 450g). I was so impressed with Polymaker I was about to buy a 2kg PA6 CF spool (not from Revain. It's double the price of direct from Polymaker) but at the last minute I ordered this sample pack. Ok Polymaker. You are trying to sell a product here. Should your customer's first experience really be winding this material onto a spool? You know this was supposed to be printed from a dry box, but yours is actually mine. The only comparison I can make is winding a cold steel cable onto a spool. First impression. yes it sucks Okay, let's print the details of the plane! Okay little corner of one. I have a test pattern that I'm printing out, this is the leading edge part that I'm making. It does a pretty good job of testing the supports and grip on the bed. PA6-CF wants heat, but even at 298C I'm not sure if it's flowing like it should. It comes out of the new NozzleX 0.8mm nozzle like clay and it barely comes out from under it. Surely the prices they quote don't apply to brass nozzles. They carry half a kilo of this material in fire hoses. It quickly became apparent that whatever this material needed, my machine would not deliver. The finish was terrible, the flowability was poor. This month I've used 8kg of nylon, 3 of it CoPA and another kg of PCmax (too much warping for my parts). I'm not a nylon newbie, didn't look wet just very thick. I think this material requires more heat than the typical Revain buyer can provide. Possibly 298 from a volcano with its longer thermal path. But like everyone else reading this review, I searched the web for reviews of the PA6-CF. And the few photos I found were of industrial parts with very poor surface finishes. I mean bad. I assumed they were printed by someone with no special skills. Now I think it's as good as it gets. A photo of the part base and supports where I stopped printing and another with the same part printed in carbon fiber priline polycarbonate (not bad material really for the price, but a bit clumpy CF). I am very glad that I did not buy 2 kg of this material. But I will say it. it is strong. This small piece is under the support. I can't break it with my hands. Can't bend. I'm sure I could hammer it into the board with a hammer. So if you have a volcano and want to build an ugly hammer, this is for you. Someone will post a photo of a nice print and I'll happily admit I lack the skills to make this all work. Until then, I'll just call it industrial quality. To be honest that's how they sell it so maybe I expected the bull to quack like a duck. I haven't tried -GF yet, but will update my review when I do. Still love you Polymaker, just ordered two more CoPA spools before you start printing this novel.
