Low-cost laser sintering 3D printer based on single chip microcomputers

Abstract

The invention discloses a low-cost laser sintering 3D printer based on single chip microcomputers. The low-cost laser sintering 3D printer based on the single chip microcomputers comprises a rack, a modularized powder box, a laser module, a powder laying roller, an X-shaft stepping motor, a Y-shaft stepping motor and a control system. The control system comprises the first single chip microcomputer and the second single chip microcomputer, the first single chip microcomputer is controllably connected with the laser module, the X-shaft stepping motor and the Y-shaft stepping motor, the second single chip microcomputer is controllably connected with the powder laying roller, and the first single chip microcomputer and the second single chip microcomputer are connected through a serial port to achieve interworking. According to the low-cost laser sintering 3D printer based on the single chip microcomputers, the overall structure is compact, excessive empty running situations are avoided when small pieces are printed, printing efficiency is higher when formed pieces with same size are printed, inertia generated in the moving and rotating process of devices of equipment is smaller, vibration when the whole printer runs is small, and printing precision is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a low-cost laser sintering 3D printer based on a single-chip microcomputer. Background technique [0002] At present, the existing laser sintering 3D printers in China are industrial printers. This type of printer has the following defects: 1. The printing efficiency is low. The existing laser sintering equipment has a large molding box. , there will be some devices for idle travel, resulting in unnecessary loss of equipment use and unnecessary time loss; 2. The operation is difficult. The existing laser sintering equipment is controlled by an industrial computer, and the operation of industrial-grade selective laser sintering equipment is complicated. Professional training for operators; 3. The printing accuracy is low. The existing laser sintering adopts the galvanometer scanning method, and the spot has focus distortion.
