Abstract

With the use of 3D printing technology, layer by layer extrusion is possible printing of construction objects, but printers represent a large size and mobility limited metal construction. The main reason for the large size of constructions for existing structures of 3D printers for building objects are large strains of bending moments that construction must take. In a new scheme of 3D printer called "Delta Wired 3D Printer", the large stress created from bending moments are transformed in normal stress from tension. At this time, the printer has been developed as a conceptual project is therefore theoretically necessary to identify efforts in wires which is to be suspended extruders (load). For creating a large scale working 3D printer model is necessary to create a prototype. Through a theoretical study of the basic design parameters can be made a real printer prototype project. By using the theory of similarity can be define a unit of prototype error as to how much it will respond to the real model. This is also the main purpose of this publication.
