Do anyone here have experiences with Igus filaments iglidur i150 and i151 - relatively low cost food safe filaments?
Which settings and which print plate do you use?
I would not suggest using any kind of PLA or other low temp resistant plastic for food safe FDM printing.
While PLA is non toxic, and some brands are even certified as food safe, does not mean the product you make is actually food safe.
FDM printing leaves layer lines, tiny gaps and pores on the surface of whatever you print, and no amount of tuning your printer will prevent that. These surface features of your prints will be the perfect housing for bacteria and cleaning them out will be very hard to impossible as you cannot reach high enough temps like they are used in dish washers.
You can mitigate the bacteria problem by coating it with a food safe epoxy and you can mitigate the heat resistance problem by using heat resistant filaments like ABS or PP.
Here is a site with some tips and a list of filaments being approved by the two major food safety organizations FDA and EU

I never found a need to wipe the build plate after applying it. Just wash the part afterwards and the thin layer of glue won’t be visible, at least not by normal visual inspection.
Why are you talking about glue sticks i a track about IGUS FDA approved filaments, and how to use them?
my text went to the wrong thread…
sorry
These are approved food safe materials from one of the worlds largest specialty engineering plastics manufactures.
Do anyone know how to set up a temperature tower like this from Thingiverse for print test in Bambu, because the print quality is not that good with the Igidur i150/i151 and since the material is significantly more expensive than others I’d like to adjust as quickly as possible
Use the Orca slicer. Orca has a build-in temp. test tower.

You’re correct that FDM printing can leave surface imperfections that can harbor bacteria, making it challenging to ensure food safety. While some PLA brands are certified as food safe, it doesn’t guarantee that the final printed product will be entirely food safe due to the nature of FDM printing.
To mitigate these concerns, one option is to coat the printed object with a food-safe epoxy to create a smooth and impermeable surface. This can help prevent bacteria from accumulating in the crevices.
Alternatively, using heat-resistant filaments like ABS or PP can address the heat resistance problem, as these materials can withstand higher temperatures compared to PLA.
If you’re looking for a convenient and food-safe option, you might consider exploring fresh meal delivery services. These services provide pre-prepared meals that are designed to be safe and convenient for consumption. They often follow strict food safety guidelines and can provide a reliable solution for those seeking convenient and safe food options.
Dont know why people start to complain about this filament and the food safe aspect. Did you even read what kind of filament it is? linear bearing are made of that material…and its food safe so you can use it in maschinery that is used in food processing…its not meant to use it with direct contact with food ( printed mug).
