New Intelligent, Robotic-based System for Metal Additive Manufacturing is a multi-robotic system designed for additive-manufacturing of metals using Direct Energy Deposition techniques. The system is composed by 3 sub-systems: a) A robotic-based Laser-Metal Deposition (LMD) system; b) A robotic-based wire-arc additive manufacturing system; and c) A subtractive robot- based system, that also includes features capable of 3D scanning and 3D reconstruction. The invention is based on the novel idea of printing the designed part directly from the CAD station, having all the underlying process completely automatic. It also includes simulation features, in real time, adds mixed reality for user-machine interface, and explores the digital-twin concept, i.e., the system has a twin that behaves exactly as the real one. Consequently, the twin is used to setup, printing test, etc., before proceeding with the actual printing process. The software that enables all these features is also part of this invention. It is design on cloud-based distributed programming, robot code generation (using a generic programming language) and TCP/IP connections to allow the system to include new features with time (as they become available). Consequently, the invention here presented is also designated as a development platform.
