Additive manufacturing technologies represent an interesting solution to aid companies to offer a wide range of customized products. Furthermore, they allow printing complex lattice and auxetic structures. The use of robot manipulators for 3D printing allows overcoming several limitations of traditional additive manufacturing systems, i.e. low surface quality (stair-casing effects) and undesirable anisotropic properties, so as to print complex geometries on curved surfaces. This work presents an experimental setup designed to print cylindrical auxetic structures composed of a 3D printer and a robotic arm. The system produces the part without any assembly and avoiding stair-case effects. Furthermore, using the robot for moving the printing based simplified the control system and allows for simpler printing devices.

Abstract
Additive manufacturing technologies represent an interesting solution to aid companies to offer a wide range of customized products. Furthermore, they allow printing complex lattice and auxetic structures. The use of robot manipulators for 3D printing allows overcoming several limitations of traditional additive manufacturing systems, i.e. low surface quality (stair-casing effects) and undesirable anisotropic properties, so as to print complex geometries on curved surfaces. This work presents an experimental setup designed to print cylindrical auxetic structures composed of a 3D printer and a robotic arm. The system produces the part without any assembly and avoiding stair-case effects. Furthermore, using the robot for moving the printing based simplified the control system and allows for simpler printing devices.Pubblicazioni consigliate
