SLM 3D printing, 3D prototyping, industrial 3D printing, precision 3D cnc machine, micro-machining, seven to fifteen days parameter refers to the process of producing a three-dimensional metal part using a SLM 3D printer or 3D modeling software like FNA, CNC, and MicroCAD. These processes involve precise measurements of the material being printed to ensure that the final part meets the specifications. The parameters may vary depending on the specific manufacturing process used, but some common parameters include material type (such as aluminum, steel, titanium), extruder settings (such as bed speed, feed rate, and print head diameter), tooling and safety precautions, and machine power output. The actual duration for each parameter can range from several days to several weeks, depending on the complexity and level of the finished part.
