Ultraviolet laser 3D printing method for precise temperature control of polymer material and device thereof
An ultraviolet laser 3D printing device includes a thermostat, a laser head, a non-contact type temperature monitoring device, a scanning galvanometer, a processing platform, a powder laying device, a material to be processed, a computer control system. The device is configured to perform the following functions: presetting a processing temperature by the control system; during the processing procedure, the temperature rise condition of the processed object is monitored by the non-contact type temperature monitoring device and fed back in real time to the control system; and by recording the rise value of the temperature within a certain period, the system can obtain the absorption capability of the laser and the temperature rise degree of the processed material, so that the laser output power can be calculated according to the preset processing temperature value, and the laser power can be adjusted in real time to precisely control the processing temperature.
