waterproof objects?

Recommended Posts

Not used PET but had some success with PLA, the key thing was to make the objects solid. Normal walls up to 3 layers thick with conventional 20% infill always leaked, once I moved to solid objects - no leakage. Be aware though that some fluid could seep into the Z axis layers.

Making water tight objects is very difficult since you don't have a guaranty that in between the layer is not a small hole. I paint my things that need to be water tight.

I made plenty of single wall vases that where watertight. I usually make them using spiralize, a larger nozzle (f.e. 0.8mm) and then overextrude a lot, you need to experiment per material and temperature/speed, but just try somewhere around 130% ...
