The thick film resistor paste comprises a silver powder or a palladium powder, or a mixture of both of the silver powder and the palladium powder, a ruthenium-oxide-containing glass powder and an organic vehicle, the ruthenium-oxide-containing glass powder comprises 10 to 60 mass % of ruthenium oxide, a glass composition of the ruthenium-oxide-containing glass powder comprises 3 to 60 mass % of silicon oxide, 30 to 90 mass % of lead oxide, 5 to 50 mass % of boron oxide relative to 100 mass % of glass components, and, a combined amount of silicon oxide, lead oxide and boron oxide by mass % is 50 mass % or more relative to 100 mass % of the glass components.

There is disclosed an article which is formed of a solid-phase or liquid-phase sintered product of a metal powder, ceramic powder or glass powder. For manufacturing the article, an extrudable mixture which contains the material powder and a thermoplastic binder is shaped into a continuous filament suitable for use in fused filament 3D printers. The printed object is then invested in plaster or other castable refractory. The invested object is then subjected to heating. The heating process burns off the thermoplastic binder and sinters the powders of metal, glass or ceramic, leaving a pure metal, glass or ceramic object.

The extrudable mixture is produced by preparing a material powder, preparing thermoplastic binder, blending the material powder and the thermoplastic binder together. The most preferable extrudable mixture contains 80 to 92% by weight of metal powder, 8 to 20% by weight of thermoplastic binder, and 0.0 to 0.1% unavoidable impurities. The extrudable mixture is then extruded into a continuous filament suitable for use in various 3d printing hardware.
