I’ve been having a hard time getting my nylon parts printed. I use 3M blue painter’s tape on glass on a heated bed and the nylon sticks very well too it. However, after 3 or 4 layers, the nylon warping exhibits such a big force that it lifts the blue tape from the glass. A few layers further I see delamination and the print is pretty much ruined.
Does anybody have the same experience? How did you solve it?
Hi Peter, sorry to hear about this. Here are some hubs that also use nylon, maybe they might be able to help? @PMD_prototipi@bluebox@kreynolds@Andrew_6@layfa or @Wei_3
I have not had much luck printing nylon on blue tape. I glue a sheet of copy paper to the glass plate using gluestick. I usually set the bed temp to 90c. Also make sure your nylon is dry, if in doubt put it in the oven at 180F for 6 hours.
I actually solved this problem and wish to share my experience with the community:
As it turns out, nylon sticks amazingly well to ‘solvent free’ school glue. You can pick up this glue at any school supply or art supply store. Just pick the cheapest and biggest bottle you can find and make sure it says ‘solvent free’. I don’t know why exactly, but it works. I spread it quite thick straight on the glass (forget the blue painter’s tape), and make sure it’s spread out evenly. Then I heat the bed and leave the glue to dry so it creates a nice and even opaque white layer on the glass. Then I use a brim of 5mm on my prints and no more warping!!
Next problem: improving the inter-layer adhesion. Now I notice that after 10 or so layers, the print delaminates itself (even though the bottom layers stick to the glass and stay perfectly straight). I’ll try to increase the temperature and lower the layer height. Also increasing the infill to 50%. Any other tips are most welcome!
My nylon prints do not delaminate with slower speed, a bit higher temperature then recommended, and most important, my printer is covered with a chamber I made. Just a regular plexy box to keep the heat in, and the breeze out.
Your tip was very helpful, I am looking forward to try the glue that helps prevent warping
