PLA is especially ideal for printing objects with flat surfaces, hard angles and ones requiring tight tolerances for fit. Manufacturing Process: Controlled using Non-Contact Laser Diameter Gauge:10.03 mm Tolerance. Monitored with rapid, reproducible and repeatable measurements to exact dimensional tolerances. Maintaining high consistency of dimensional accuracy Certifications: D3D Filaments are complaint with ROH Certifications: free from any potential hazardous substances including cadmium, mercury and chromium. Technical Specification Printing Temperature : 1900C - 2300C Heated Bed: PLA can be printed with or without a heated print bed, however, if your 3D printer does have a heated bed, it is recommended that you set your bed temperature to approximately 600C. First layer usually 50C-100C higher than subsequent layers. With Glow in the Dark PLA, increasing your print temperature 5 to 100c is recommended. Sticks well to Glass with PVA Glue ,BuildTak, PEI, or blue tape.
