I want to FDM 3D-print an object, and be able to effectively clean the surface with standard kitchen cleaning solutions. While the 3D-printed object would not come in direct contact with food, it would come in contact with utensils used with food (e.g. forks, measuring cups, etc.). One of my main concerns is with being able to adequately clean the object when layer lines and general material porosity create areas that dirt/germs may accumulate. I believe my general requirements are:
- No high temperatures are anticipated
- Common FDM materials (PLA, ABS, PETG)
- Coatings or post-processing is fine
How do I make a 3D-printed surface easily cleanable and relatively food-safe?
