Flexible material won't stick to build plate

Recommended Posts

Hi all,


this is my first topic, I hope I am not re-opening an existing one!


I appear to try some exotic and very flexible materials. I can not manage to have it stick correctly on the build plate. I tried basically all options I usually do : glue, PEI film on aluminium build plate, "naked" aluminium plate, different levelings. The best I reached was on naked aluminium and with a relatively high flow on a not-to-from-bed leveled nozzle...


Would any of you guys have experience on soft materials ?


Thank you very much!

What material exactly?


I have printed ninjaflex on heated glass bed with extremely thin layer of PVA glue and it was fine.  If you use glue stick then take a wet tissue and spread it around evenly.  The tissue will remove most of the PVA which is what you want.  I'm not sure but I think ninjaflex is TPU.

hi guys


The material is a relatively low shore elastomer, I am not sure of the chemical composition... I managed to have it stick to a sanded aluminium plate and adjusting the bed level. 


@gr5 : I tried the dissolved glue but the heat seemed to make the first layer move on the bed


thank you so much for your answers!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
