Polylactic acid filaments were printed into tensile specimens using a 3D printer. The sample size should comply with the provisions of 6.1 in GB/T1040.2-2006, and type 1A samples should be used. Recommended printing parameters: printing temperature 210℃, hot bed temperature 50℃, printing speed 80mm/s, vertical printing. If other printing parameters are used, they must be noted in the report. According to the regulations of GB/T1040.2-2006, the recommended speed is 10mm/min. If other speeds are used, this must be noted in the report. Follow the provisions of Chapter 10 of GB/T1040.1-2006.
