Embodiment Construction
[0034] The technical features of the present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can understand.
[0035] A method for additive manufacturing of a plastic powder conformal stepped temperature bed, comprising the following steps:
[0036] A. Slice the 3D digital model of the plastic product under a specific software and generate a file that expands the laser scanning path of the selected area a2 and sintering area a3, and then import the file into the laser sintering additive manufacturing system;
[0037] B. Adding powder: Add the plastic powder for sintering into the powder tank composed of powder spreading device;
[0038] C. Powder scraping: The scraper with plastic powder added to the powder tank moves on the working platform, and the plastic powder in the powder tank is evenly spread on the working platform through the scraper;
[0039] D. Primary heating: heat the plastic powd...
