Building Platform for Identification of Important Parameters for 3D Printing of Huge Parts

3D printing of big and very big parts is used mostly in mechanical engineering, automotive industry and industrial design. 3D printing can be used to manufacture prototypes of complicated shapes, which could not be manufactured using different technologies and it is not needed to manufacture expansive tools. To be able to print enormous parts with FDM technology many obstacles must be overcome and several unknown parameters have to be revealed. Primary focus of research and development in this paper is description of building process of experimental device, which will be used to identify important parameters of printing process of huge parts. Some and most important of these parameters are supposed to be influence of scanning speed as well as speed of filament movement and influence of melting temperature. Very important issue to observe and take care of is thermal stress inside the printed material and of course final strength of the part. We assume that we will be able to show experimentally that all of these parameters are important and influence the final part quality.
