Abstract

The invention provides a quick forming device and method based on a femtosecond laser and ion beam composite technology. The device mainly comprises a nanosecond-picosecond-femtosecond laser device, an ion beam device and a real-time monitoring system, nanosecond laser is used for conducting scanning sintering on raw materials, the real-time monitoring system performs real-time processing, part morphology, microcosmic structure and ingredient measurement and analysis and feeds analysis results to a control system, and the nanosecond-picosecond-femtosecond laser, ion beams and the real-time monitoring system forma closed-loop system so as to effectively machining and detection coordination if picoseconds laser, femtosecond laser or ion beams are needed to perform further finish machining. The quick forming device and method achieve quick forming of complicated parts and precise machining of the microcosmic structure, improve the microcosmic structure and quality control capacity by using the real-time monitoring system and is used for manufacturing high-strength, high-accuracy and complicated-structure parts.

Description

technical field [0001] The invention relates to the field of rapid prototyping, in particular to a method based on femtosecond laser and ion beam [0002] Rapid prototyping equipment and methods for composite technology. Background technique [0003] Rapid prototyping technology is a manufacturing method that uses materials to build up devices layer by layer or point by point. It mainly converts three-dimensional parts into a series of two-dimensional components through comprehensive mechanical engineering, CAD, numerical control technology, laser technology and materials. Superposition of part section fabrication. For metal materials, laser sintering is currently commonly used to sinter or melt metal powder under gas protection, but ordinary laser rapid prototyping appears to be difficult when sintering certain special metals such as tungsten, titanium and high-temperature alloys. Disadvantages such as low strength, powder blowing, spheroidization, high residual stress an...
