FDM 3D Printer
In 2015 i designed and build a custom 3d printer for personal use. The external dimensions are around 500x500x500mm with build size 300x300x300mm, this was bigger than the consumer hobby machines such as Makebot, Ultimaker etc.
The electronics and firmware on the first version of the Printer were an Arduino Mega 2560 R3 with Ramps 1.4 running Marlin. There was an addition embedded system running Linux and a print-server which added wifi connectivity and web interface. The current version of the printer, v3, is completely redesigned and has a controller with 32bit processor and a display/UI interface with wifi connectivity.
