Is a 3D-printed mug watertight?

A 3D-printed mug can be waterproof to a certain extent, but its complete sealing depends on several factors, such as the printing material, the print quality, the surface condition of the mug, etc. Typically, 3D-printed plastic mugs may have microscopic pores or imperfections through which liquid can leak under pressure or certain conditions. For complete sealing, it is recommended to use specialized materials and printing technologies or add post-printing treatments to ensure the mug's integrity. It is impossible to accurately determine whether a mug is completely sealed without additional information about the material, 3D printing technology, and post-printing measures.
