Using PVA to make Nylon stick and give a flat bottom.  

Using PVA to make Nylon stick and give a flat bottom.

Hey all,

I'm making a router base prototype and have issues with nylon sticking.

What I have done in the past is simply used PETG essentially as a shellac, a universal bonder.

I grab my model, extrude the bottom 0.5mm, and put in a 'colour change' after that and switch filaments.

I want to try with with PVA, but also want to take advantage of ironing.

I have my model, I've extruded 0.5mm at the bottom, but I can't get "all solid surfaces' to act as I thought it was supposed to.

Essentially I want the first layer to be put down as normal (0.3mm @ 0.8mm wide), then the second layer (0.2mm @ 0.4mm wide), then have that second layer ironed, trigger a filament change, and print the nylon on top.

I can't for the life of my figure out how to make PrusaSlicer do what I want here. Anyone have any suggestions?

Cheers 👍
