Research On Control System Of Fdm Rapid Prototyping Machine

3D printing is an advanced manufacturing technology,which developed rapidly in recent years and has been widely adopted.The control system is the core part of 3D printer.Its level has a decisive influence on the printing performance,such as speed,precision,surface quality and equipment life,etc.This paper describes the control system to the stepper motor drive fused deposition modeling(FDM)3D printer for the application of the principles of object-compatible series and parallel structure.Content with motion control technology as the main line,the control system hardware design,key algorithms and methods to optimize a complete presentation.Including the structure and function of the control system overview,system control circuit parameters and the basic principles of the main modules,checking methods and considerations,numerical analysis and instruction Delta parallel linear interpolation principles and implementation of optimization methods have the ability to forward-looking small efficient and smooth line segment speed convergence algorithm to adapt the stepper motor acceleration and deceleration characteristics of piecewise linear programming algorithm.Algorithm for Geometric and physical meaning of this article describes intuitive,logical,easy to implement,algorithm implementation and optimization techniques have been fully explained,has a strong practical.The main content of this paper put into use on SS-2A and SS-Cell two series 3D printer Harbin YaZhi technology Ltd.produced,compared with the same grade of product,the print speed by 50-100%,finished size Print accuracy and surface quality are greatly improved.
