Hi all. I am currently working on a project at my job where I am trying to print using HDPE. The full-scale version I am trying to mimic is made out of HDPE. However, I have read that the HDPE material is extremely hard to print. Are there any alternatives that have similar leachable properties (i.e., very stable). I am not looking at strength properties, only the chemical properties of the material. Any suggestions of Ultimaker materials (or 3rd party) which is similar in this way to HDPE? Or is there any good Cura recipe out ther for HDPE printing using Ulitmaker S3? Thanks in advance, Siggi
