Hi everyone, Wich materials can I use to make a drinking cup from? Waterproof and what can be the minimal wall tickness Thank you in advance
To add on to what you found and Virtox added, Ceramics is the only certified food safe material. This is because the glazing process is a certified food safe process. So if you us another material, it would be up to you to use a food safe process to make it work.
Okay I Uploaded my model! Do you think 2,5 mm wall tickness also be strong enough? have any experience with it? Tnx
The minimum wall thickness for ceramics is 3 mm or more depending on the size: Min Wall Supported: If bounding box x+y+z is 120-200mm: 3mm x+y+z is 200-300mm, min wall should be 4mm x+y+z is 300-400mm, min wall should be 6mm And if you want a hollow cavity in a model there needs to be a hole for the "support" material to get out: Min Escape Hole: 10-15mm diameter You can read all the details here: https://www.shapeways.com/materials/ceramics-design-guideline s
Thanks for your help didn't notice it before I moddeld a hole in it. All of sudden it's way more expensive almost twice as much, and the hole is not showing up in all the pictures Is this normal?
Ceramics is special in that it is priced per surface area, not per volume. (Suggests that the glazing is an order of magnitude more expensive than the clay). So adding holes can actually make your model more expensive in ceramics.
