A method for making stainless steel texture component in building landscape model by 3D printing, uses polylactic acid-chromium powder composite 3D printing wire, and based on fused deposition, the 3D printer can be used for printing and manufacturing. The polylactic acid-chromium powder composite 3D printing wire is a 3D printing wire with diameter of 1.75mm or 3mm produced by mixing the polylactic acid and the chromium powder and then producing by a screw extruder. Compared with the prior art, the method for making stainless steel texture component in building landscape model by 3D printing has the advantages of being rapid and environmental friendly and low in cost. Firstly, all kinds of 3D softwares can be used for the rapid modeling of the product design; the polylactic acid is derived from the biopolymer materials of starch, and is a completely biodegradable and environmentally friendly material, and the fused printing of the 3D printing wire composed of polylactic acid-chromium powder can be performed at 190-210 DEG C, which is lower than the temperature of laser melting metal stainless steel 3D printing. The method for making stainless steel texture component in building landscape model by 3D printing has low energy consumption and low cost, and the printed building and environment designed component has good quality and good effects.
