An exothermic welding container (100) can be formed, including as a single-use or other welding mold with a welding chamber (104) and crucible chamber (102). The welding container can be printed using additive manufacturing methods, including via binder jet printing with ceramic or other fines and a binder of furfuryl alcohol or phenolic materials. An additive manufacturing system can iteratively deposit and fuse layers of material (150A, 150B, 150C) to create a three-dimensional exothermic welding container in accordance with a digital model of the welding container.

A hydrophilic anti-fog nano paint for endoscope is provided. The paint includes, in parts by weight, 1-10 parts of plant polyphenols, 0.1-2 parts of metal ions, 0.1-0.5 parts of biomass molecules, 10-20 parts of additives and 250 parts of solvents. When coated on a substrate surface and dried, the paint forms a coating in which the plant polyphenols and metal ions combine to form a plant polyphenol-metal nano complex. Together with biomass molecules, the plant polyphenol-metal nano complex produces a hydrophilic nanofilm on the laparoscope surface, thereby enhancing the hydrophilicity of the lens interface.
