The best flow rate is 0. 3dmakerengineering. Excessive screw and barrel wear comes with rate and quality loss and rising energy consumption. I want to programatically generate G-code for a (Marlin-based) Ultimaker 2+ printer, and I have been looking at the Marlin documentation and working G-code examples generated by Cura. The Compuplast ® Extrusion Calculator ™ allows the user to quickly and easily determine the flow characteristics in the most common types of flow geometries found in extrusion like Tubes, Plates, Annuli and Screw Channels. Lower stress means less energy is put into melting the polymer. Certain materials, such as PP, do not follow the normal trends so a tuning factor has been added for those materials. Interactive calculator for the calculation of flow rate from extrusion speed or extrusion speed from flow rate. The Slic3r software has a calculation which sets extrusion width to 1. ra wz nl wc qp wc ma ml gi dm
