ABSTRACT
MX3D is a design firm, which has developed the capabilities to print in thin air using various metal extrusions. The technique uses a method in which many researchers are finding more flexibility, using a 6-axis robotic arm instead of traditional CNC machinery. The innovative flexibility of this system is driven primarily by the ability to use a robotic arm, which can move, with precision, anywhere in a three-dimensional field, and extrude a structural metal line along its path. The system, which MX3D developed can print with steel, stainless steel, aluminum, bronze, or copper. For different types of geometric movements by the arm, the welding tool settings must be adjusted. The programming software developed by MX3D is able to interface between the robot movement and the welder. MX3D's system progresses along each path relatively equally to ensure that connections between linear elements are made when needed and that no one line becomes too long for its base to support.
