  1. @RuCad Selecting CPE is indeed the easiest way to solve the problem, since PETG is a CPE (co-polyester).
  2. Today I was going through the Ultimaker maintenance schedule. I noticed that information about the lubrication of the lift switch was missing. That made me wondering about any need to reapply lubrication, especially since the switch is visibly lubricated. An extra section about the lift switch lubrication (or a remark about the lack of any need to reapply lubrication, if that is the case) would be helpful.
  3. @geert_2 thank you for your advice! I was thinking of Pla smoothing myself for phase one. In the meantime, I also read the most relevant chapters of PLASTICS IN MEDICAL DEVICES: PROPERTIES, REQUIREMENTS, AND APPLICATIONS by Vinny R. Sastri. Based on the information of the book, I will probably use PP for phase two. I can recommend this book to anyone who is dealing with similar situations (despite the lack of information about FFF). The book is detailed yet self-explanatory.
  4. @SandervG I found the problem it is not possible to use a "." (period) in the company name so the registration name had to be used.
  5. Hi @SandervG I’ve tried several times today, right now I am still encountering the same problem.
  6. Dear Ultimaker Community, hopefully one of you could help me out with a material choice my current research project. I am involved in the development of an open-source swallowing sensor for Parkinson patients. At this stage I am trying to find the right material for functional prototyping. The sensor will consist of some small parts in a FFF printed housing which will be placed around the neck. Some of the main requirements/criteria for the material choice are: -The material should not absorb to much kinetic energy since vibrations of the throat are used to measure swal
  7. Hello, I am currently unable to register for the summit. After filling in the contact page the following error page is displayed. Is there a way to fix this?
  8. @herzla In my experience it is best to manually export files to STL within Solidsworks. This gives you maximum control over your STL properties. To adjust STL settings you should go to system options > Export > file format STL. Make sure the Binary option is selected, since ASCII files can easily be 6-8x the size. The preview option really helps to identify the different parameters. After the export you can open the file in Cura. But remember @gr5’s advice about having to many points.
  9. Hi @bassamanator. First a small disclaimer: This is my first post and I'm fairly new to 3d printing and especially using an ultimaker. I had the same problem with a cylindrical object and cura 4.8 a few days ago. There are a lot of settings in cura that can help with this problem. For instance: adjusting the Outer wall wipe distance, turn of wall overlap compensation changing the max comb distance without retraction or experiment with Z hop settings. However, I just kept on having problems until I lowered the STL refinement in my CAD software (fusion 360). I do not now exactly why
