▎ 摘　　要

NOVELTY - The printer has a case (1) whose inner portion is provided with a sealed printing space (15). A side wall of case is provided with a double insulating layer (12), a cooling layer (13) and an inner case layer (14). A mounting space (16) is formed between the case layer and the double-insulating layer. A printing device (2) is installed in the case. The printing device in case is provided with a printing head (21). A printing substrate (22) places the printing object. A driving device (3) drives the printing head to move in the three-axis direction. A temperature control device controls the printing environment temperature. The control units (41-43) are arranged in control device for controlling temperature of the printing head, printing substrate, and temperature in the case. USE - High performance polymer additive manufacturing three-dimensional (3D) printer for use in industrial field, aerospace field and medical field. ADVANTAGE - The three target temperature heating system of printing space is heated by printing head, so as to improve the printing success rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high performance polymer additive manufacturing 3D printing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the printer.
