SLM printing control system

Abstract

The invention discloses an SLM printing control system which comprises a PLC control system, a two-shaft galvanometer scanning system, a power feeding cylinder servo motor, a molding cylinder servo motor, a powder paving scraper servo motor and a laser device which are connected through a PROFINET (Ethernet) communication bus. The PLC control system is a total control center and is used for controlling coordination work of all modules, a PC upper computer controls the two-shaft galvanometer scanning system through an RTC4 control card, the PLC control system feeds powder to a working table through the power feeding cylinder servo motor, the molding cylinder servo motor is started to be used for driving a molding cavity to fall, and then the powder paving scraper servo motor is used for evenly paving raw material powder on the working table to the molding cavity. According to the SLM printing control system, the problems that in the prior art, an SLM printing control system is poor in control accuracy, the printing product quality is influenced in the using process, and faults are prone to being caused in the using process are solved.

Description

technical field [0001] The invention relates to the field of SLM printing control, in particular to an SLM printing control system. Background technique [0002] Selective laser melting (SLM for short) is a widely used rapid prototyping technology. It uses metal powder materials as raw materials and uses laser to scan the cross-section of a three-dimensional entity layer by layer to complete prototype manufacturing, which is not limited by the complexity of the part shape. , does not require any tooling and molds, and has a wide range of applications. [0003] In the SLM printer, the control system is required to control the work before each module, so as to realize the automatic printing process, but the control accuracy of the SLM printer control system in the prior art is poor, which will affect the quality of the printed product during use, and the system is easy to use during use. malfunction. [0004] Therefore, it is an urgent problem to be solved in the present inv...
