3DPrinterOS is an easy way to use complete software packages for 3D printers (Firmware, Software, Cloud platforms etc.). The system covers every aspect of 3D printing and advanced manufacturing workflows, solving the fragmentation of many disparate 3D printers and their associated software. 3DPrinterOS is like Android for 3D printers. Users can go directly from CAD to STL/OBJ/Step, prepare a build tray allocation, slice for 150+ types of desktop 3D printers or queue for 1200+ industrial 3D printers. The system can also monitor real time prints and share projects and printers with your colleagues or friends.
