Ultimaker Nylon is not sticking to the build plate at all. How can I fix this?

Recommended Posts

Hello all,

We've had an Ultimaker 2+ for a few months now, and generally haven't had any issues. I recently switched the material to Nylon and attempted a small print, and have had complete and utter failure to get any build plate adhesion. Here are the details.

Default Nylon settings in Cura. Running at 0.25mm nozzle diameter.

Swapped in the 0.25mm nozzle.

Verified the build platform is heating and leveled properly.

Attempted a glue stick layer with no success.

The nylon just won't stay on the platform. The print is a disaster within the first 10 seconds of the build. By all accounts, I've heard that the nylon is supposed to have good adhesion - what am I doing wrong? Any advice is appreciated!

for Nylon and PC,

I use painter tape and spray isopropyl alcohol and whip it down,

then I use stick glue and put it down where the print is going to go,

then use a paper towel over my finger to smooth it down.

Then after the brim is done and the print starts I put painters tape over

the brim to stick it to the tape on the glass, around the back and sides of the part because that is where my prints start to warp.

I have very good luck without warping on smaller parts, the longer the print

the easier it is to warp.
