Trying to print with Nylon
I'm trying to print some parts with nylon but I am having problems with curling on the bottom. I am using Matterhacker White Nylon using the Taulman Bridge profile. Other than the bottom edges lifting the parts generally look good and are sticking to the build plate. I am printing a breeze shield as well and the entire Mk3S printer is placed inside a cardboard box. I have a brim of 10 perimeters. Because I am looking for water tightness, I am trying to use 12 perimeters and 100% infill. One part is somewhat long and thin which I don't think is helping. The other part has a large flat base and is also showing some curling, but much less than the first part. Can anyone give me guidance on how to print this part well? Thank you.

I may be way off base here but I thought Taulman Bridge was formulated to allow lower temperatures.

Well, the Matterhacker Nylon is rated for 230-250C on the nozzle and 55-65C on the bed. Taulman Bridge is rated at 250-260C on the nozzle and 70-80C on the bed. PrusaSlicer is running 240C/60C (nozzle/bed) on the first layer and 250C/90C on the other layers.
The extrusion temp seems fine, but does it help for a warmer bed or a cooler bed for it to stop curling? I figured a warmer bed is best to prevent the edges for curling up. No?

Perhaps some adhesion helper? Personally I'm very confused about such products, I've seen the same product suggested for used to help both separation and adhesion, which seems counter intuitive.

I am using PVA glue. What other adhesion helper would you recommend?
