A Reliable, Precise and Efficient 3D Printer Process Controlling Algorithm

Abstract

Practical 3D printing application always encounters motor motion confliction and warping of ugly product. This paper presents the proper ways to solve these problems. Firstly, to be assured precise motion controlling, safety and 3D printing process stabilization, we present motion mutex approach with Karnaugh map for real time monitoring motor motion status, and its algorithm of motion mutex, based on this way to make motor motion coordination working to accomplish precise process controlling. Secondly, to obtain reliable and precise product with smooth surface and to reduce the time of fabrication product, we propose comprehensive path planning to achieve this purpose, which integrated contour offset scanning and short linear scanning. Finally, with these methods in the practice we have produced the beautiful statuette of warrior.
