Rest in peace granny, taken from us by a cocktail of plastics, bacteria, mold and tea. Maybe stating the obvious but 3D printed parts usually aren't food safe unless you post-process them with an appropriate non-porous coating.
- andai 2y agoWhat's your favorite non-porous teapot coating?
- timonoko 2y agoNo coating needed. All you need is to re-flow the ABS. Feels like pottery after this simple operation: https://youtu.be/iLaGJwCCz-E?si=a1gccp8EI9sGzt-e https://youtu.be/iLaGJwCCz-E?si=a1gccp8EI9sGzt-e
- echoangle 2y agoDo you really want almost-boiling-water in ABS? I wouldn't do that.
- timonoko 2y agoReflow happens at 200°C, out gassing any 3D-related harmful stuff. Equal to inject-molded ABS cutlery.
- echoangle 2y agoMaybe I'm too careful but I wouldn't use plastic cutlery on hot food either. Also, the glass transition temperature of ABS is only 105 °C, so It's probably not too strong when filled with 100 °C water.
- timonoko 2y agoI have already made all kinds of tests. Only restriction was that you cannot make open flame cooking pot, because it starts combusting too easily.
- echoangle 2y agoHow did you test the water quality after storing it in an ABS container? How would you notice if something from the ABS dissolved in the water?
