Current State and Prospects of Development of Kinematic Schemes of 3D Printers

Nowadays, additive manufacturing or 3D printing technologies are very popular. The kinematic scheme of a 3D printer determines how the movement of motors will affect the movement of the working carriage relative to the product. This paper presents an analysis of different kinematic schemes of 3D printers. A comparative analysis of kinematic schemes was carried out, the results of the analysis of various sources are integrated, the conclusions obtained in the course of the work are substantiated. Abstraction and harmonization of descriptions and visual representations of kinematic schemes from classical solutions to new ones that remain within the prototype were made. On the basis of the obtained results a generalization has been carried out, allowing to draw conclusions about the tendencies of development of the scientific direction. Recommendations for the development of a generalized mathematical model of the mechanism of movement of the working tool are given. The practical significance of the work consists in improving the characteristics of devices and printing quality, as well as reducing production costs due to the optimization of design processes; in addition, the description of the mathematical model will accelerate the creation of digital twins, and the adaptation of devices to new technologies; also the results of the study can find application for training and development of personnel.
