Designing a Hybryd Equipment for Additive Manufacturing

Abstract

In terms of the development of 3D printers we can say that in the first stage of evolution the huge majority of them were able to print 3D using 3 axis numerically controlled. Currently there are several types of printers that can print in 4 and 5-axis developed using classical solutions (portal or parallel structure). Another direction of development is the combination of 3D printers and traditional manufacturing equipment, with an already existing commercial solution (Hermle MPA 40) that combines milling and MPA technology (Metal Powder-Application). This paper presents a hybrid equipment that can be placed in the specific additive manufacturing category, combining milling operations (4 axis) and turning with 3D printing using FDM technology. The machine uses stepper motors for driving kinematic axes, a DC motor (16 000 rev / min) to drive the main shaft of the mill and a three-phase motor for turning. The software used for milling and turning is Mach3, while MatterControl is used for 3D printing.
