An Study Regarding a New Concept of 3D Printing Using a 6 Axis Industrial Robotic ARM

This paper focuses on a topic that is frequently used nowadays namely 3D printing. The term 3D printing encompasses several manufacturing technologies that build parts layer-by-layer an inconvenience of this process is that the deposition of material takes place in the plane (2D space) then by applying a constant increment on the third axis it is moved to the next plane. The deposition of material is taking part in a 2D space. There are many types of 3D printing such as FDM (fused deposition modeling), SLA (stereolitography), SLS (selective laser sintering), DMLS (direct metal laser sintering), DLP (digital light process), EBM (electron beam melting). Typically these applications involve low-volumes and complex geometries. Often, components for aerospace and medical applications are ideal candidates for production 3D printing. This paper proposes a new approach to the 3d printing process by using a robotic arm to ensure more than 3 degrees of freedom and deposition paths with spatial orientation. One propose two types of working: nonplanar with the tip normal to the working plane and nonplanar with the tip normal to the trajectory.
