Abstract : At first, 3D printing FDM printers were limited to printing one filament at a time because there was only one nozzle. With the development of double extruders in recent years, the printout can print parts consisting of two or more materials. With the ability of a double extruder printer that still has to maintain and care for both extruders, it will take up quite a lot of time. Therefore, developing a 3D engine design using the VDI 2221 method is necessary. The VDI 2221 design method is used to
