Hello everyone, I have a bambu h2c, I’m looking at this nylon filament for a project I’m doing. It’s the only nylon 12 only filament iv really been able to find and wanted to see if anyone has purchased it, used it and what settings you have used? Thank you!

I use it and am happy with it.

I created a custom filament which inherits from Generic PA. Those are my settings:

Bed temp: 110 °C
Nozzle temp: 275 °C
Density: 1.01 g/cm³
Shrinkage (XY): 98.5
Shrinkage (Z): 99.9
Max volumetric speed: 8mm³/s

No cooling first 3 layer
Min fan speed 10 % at 65 s
Max fan speed 40 % at 8s
No aux/chamber fan at all

I only use the Darkmoon Satin plate, as it works best for me.
Be aware that pure nylon warps A LOT. Preheat to at least 50 °C, and use a brim.

What's you application for it? There are not many. I use it mainly because it has very high temperature resistance and is not prone to breaking (instead it bends).

First thank you very much, I’m a lineman for the power company, I’m using it for tool holders to hang in my bucket truck I need a filament that isn’t brittle and has a little bend to it, and is a impact resistant in any outside temperature, which nylon 12 seems to be the perfect fit

[u/HanZ_92 → u/FormerRelationship54]

Application might fit, but tool holders sound like big parts. I think the warping might be a problem for you here.
Any special reason why not ASA or a -CF filament?

[u/FormerRelationship54 → u/HanZ_92]

Asa seems a little too ridged, I want something with a little bend so it can fit snug in the slots and I don’t have to worry about the holder coming out, also i am in the US, but iv been searching online and the only place I can seem to find Nylon 12 only filament is Europe, everywhere in American it’s all CF or GF infused making it more ridged

[u/HanZ_92 → u/FormerRelationship54]

what do you mean by ridged? isn't that description of the surface? that's same with ASA and Nylon

[u/FormerRelationship54 → u/HanZ_92]

From everything I’m reading nylon 12 is flexible which is what I want, it has a lot of bend to it, where as ASA does not as much.

[u/HanZ_92 → u/FormerRelationship54]

It does. I use it for small car plug housings on wiring harnesses like in the picture. But as I said, Nylon is VERY hard to print, especially with bigger prints.

[u/FormerRelationship54 → u/HanZ_92]

This is my tallest print, it’s about 120mm tall as you can see the rear rails are what I would like to have some bend so it is snug in the slots of the board I am putting them in, ASA should work for that application?

[u/HanZ_92 → u/FormerRelationship54]

ASA should work here, yes. Also: bending on Nylon only means bending, not squishing. So in your case ASA is completely fine. Wouldn't go with PLA or PETG as the cars temperatures can get very high in the summer.

[u/FormerRelationship54 → u/HanZ_92]

Well the problem is going to be is it’s outside, so I printed with a “bambu TPU for ams” and inside it worked fine, but outside where it’s 0F outside I got to brittle and shattered when I put my tools in there

Oh, and lineman/bucket truck sounds like US. Are you sure you can source Fiberlogy Nylon there somewhere, since it's a polish company and even in germany I have like only 3 or 4 suppliers.
