Which is the best filament for linear guide applications, i.e. which has the best sliding properties? For example, as a slider in an aluminium profile.
When Polymaker offers a product on par with Taulman's PCTPE (in terms of flexibility in that middle-ground arena and similar to Flashforge's Nylon PA), I'll buy it. Hopefully it will also deliver Polymaker's solid warp-free tech, moisture resistance, and colour consistency in the one product 🤞
I've order both Copa and PA-6 filament because I am convinced that it will hold up to it' expectations. I will let you guy's know of my results once I've printed some parts
Is PA6 UV resistant ? as far as I know PA12 is UV resistant, and standard PA6 not so much, that would be very interesting for me for long term durability of the parts.
Can you clarify why at 3:09 it says CoPA has high impact strength when the specs on your website says its Charpy Impact Strength: is 9.6 kJ/m2, which is lower than that of all the materials in this list? (16.5, 13.34 and 12.52)
Hi Julien, CoPA scores a 9.6 kJ/m2 in its dry state properties, however, it scores 17.2 kJ/m2 in its wet state properties. We assume that all CoPA printed parts will end up in their wet state properties as the nylon will absorb water molecules from the air. These water molecules form a polar bond on the nylon polymer chain and act as a plasticizer, making the material tougher and more impact resistant. This is why we see an increase in impact resistance from dry to wet state properties. We list both states as some customers prefer the dry state properties and would like to preserve these with a water barrier coating (paint, resin, lacquer). At 17.2kJ/m2, CoPA has a higher impact resistance than PA12-CF (wet), PolyLite ABS, PolyLite PLA Pro, PolyMax PETG, PolyLite PC, all of which we would consider tough materials.

Can you please release your pa6 gf30 in black instead of grey? I have to go to other brands for black and rather stay within your phenomenal product line.
Unfortunately we don't have any plans to produce PA6-GF in black at this time. The carbon fibers in PA6-CF naturally colour the filament black which could be an option for you if you require black colours parts. Otherwise, your request has been noted and we will look into future developments of PA6-GF in different colours as we expand our portfolio.
Thanks for the very informative video, but...If you're going to throw up data and charts, perhaps try leaving them on the screen long enough to actually read them. ;-) Yeah, we have pause buttons, but YT clutters up paused videos to the point they're unsee-able.
@@josiahong5177 The Glass fibers are cheaper than the raw nylon. CoPA also is a co-polymer combining both Nylon 6 and Nylon 6.6. Creating this filament requires more compounding and processing in the production of the filament which is reflected in the price.
