~178 DEG C, five 172~178 DEG C of area's temperature, six 172~178 DEG C of area's temperature, seven 167~173 DEG C of area's temperature, melt extrusion cooling
Crush afterwards and pellet is obtained；
Step 6, wire-drawing shape：Pellet obtained in step 5 is added to high-accuracy 3D printing consumptive material extrusion test machine, wire drawing is carried out
Shaping, the parameter of wire-drawing shape extruder is set to：38~42 DEG C of water temperature, 162~168 DEG C of one area of barrel, the area 167 of barrel two~
173 DEG C, 167~173 DEG C of mould, main frame speed is set as 40~45Hz, and hauling speed is set as 24~27Hz, obtains melting heavy
Product shaping wheat straw powder composite wire.
10. one of a kind of claim 1-8 described fused glass pellets 3D printing method of wheat straw powder composite wire, it is special
Levy and be：Comprise the following steps：
Step A, go out corresponding three-dimensional entity model using three-dimensional drawing Software on Drawing, and save as the file of .stl forms, lead
Enter in Slice Software；
Step B, the corresponding printing type of setting, packed density is 0~100%, and thickness is 0.2mm~0.7mm, and print speed is
20mm/s~60mm/s, print temperature is 190 DEG C~240 DEG C；
The parameter that step A, step B are set is saved as the recognizable printing path Gcode of 3D printer by step C, Slice Software
Code, 3D printer is operated under the guide of code, and successively accumulation, Layered manufacturing, print three-dimensional entity model.
