Design and implementation of a 3D photocopier with photogrammetric method using linear delta robot

In the present article, the design and construction of a 3D photocopier is discussed. This device has two main units: 3D scanner unit and 3D printer unit. Today, the need to use 3D scanners in various applications such as quality control, reverse engineering, and computer aided design and production is growing. This machine will be able to take 3D scanning and after processing the scanned image, sends a 3D model to the 3D printer unit for printing and makes a copy model of that part. One of the salient advantages of this design is its use in reverse engineering. It can make a copy model with the desired fit of a workpiece without the need for a measurement process to determine the dimensions, followed by the design process, which in many cases due to the apparent complexity of the workpiece is long, difficult and time consuming, in the least make time. It is possible to repair or change the part after taking the scan, and then send it to the 3D printer unit. Scanning the piece uses the photogrammetric method. 3D printers work with different mechanisms and technologies, the printer movement mechanism is inspired by the delta robot mechanism and printing technology, and extrusion (melting) of raw materials has been selected. The rules and principles of designing and building a 3D printer are explained. It is stated how the observance of these principles and rules will be effective in increasing the accuracy and quality of manufactured parts.
