Multi-Station Multi-Axis - Hybrid Layered Manufacturing (MSMA-HLM)

Multi-Station Multi-Axis - Hybrid Layered Manufacturing (MSMA-HLM) is a metal 3D printing machine and it enables different levels of process hybridization and integration of multiple technologies. The various levels of process hybridization may comprise of an optimal use of: different modes of manufacturing like subtractive/additive/transformative; different cladding methods like MIG/TIG/LASER/EB; different kinematics like three-axis/five-axis, series or parallel; different layering strategies like horizontal/conformal. This machine has seven stations, three for depositing material, two for residual stress management, one for machining, and one for image processing. All these stations and other operations are controlled by a Siemens 840D sl controller. The technologies may include of: machining for geometrical accuracy, hammering and induction pre-heating for residual stress management, and optical inspection for crack and surface porosity detection. It can build complex metallic objects which could find applications in automobile, aerospace, medical as well as heavy engineering.
