Compound rapid forming method and device by integration of light solidification and fusion sediment

Abstract

This invention relates to integrate composite quickspeed forming method composed light solidifying forming method and fusion sedimentation and devices. Form outer fine contour with light solidifying forming method and inner block zone. The device comprises corresponding two systems and form-head auto switching system controlled by microcomputer control system. This invention integrates advances of two quickspeed forming methods and overcomes their shortcomings; the former has high forming precision, strong preparation details capability and well surface quality; the latter fits to large range materials and needs low cost. It fits to many members precision preparation.

Description

technical field [0001] The invention relates to a rapid prototyping method and device of a rapid prototyping process, in particular to a composite rapid prototyping method and device integrating light curing and fusion deposition. Background technique: [0002] Rapid Prototyping & Manufacturing (RPM) technology is a high-tech manufacturing technology developed in the late 1980s. It completely breaks through the traditional manufacturing mode and realizes the integral forming of arbitrary complex parts based on the material accumulation method. The impact on the industry is comparable to that of numerical control technology. The earliest RPM method was the Stereolithography-SL method using laser as the forming energy source. Mitsubishi Corporation of Japan applied for the first patent of SL in 1974, but gave up soon; Dr. Kodama of the Nagoya Prefecture Institute of Japan Another patent was applied for in 1980, but it was also abandoned in 1987; then Charles Hull of UVP Compa...

AI Technical Summary

Problems solved by technology

[0006] (2) Due to the limitation of the material, the mechanical and mechanical properties of the formed prototype are poor, and it is easy to deform, which affects the subsequent mold manufacturing accuracy;

[0007] (3) The SL method mainly uses laser as the forming energy source, and the price and maintenance cost of the laser system (including laser, cooler, power supply and external optical path) are expensive, and the resin material is also relatively expensive, so the production cost is relatively high

[0011] To sum up, different RPM process methods have their own advantages and disadvantages, but they all have limitations in one way or another in terms of forming accuracy, efficiency, cost, materials, and prototype performance. However, with the deepening of the application of RPM technology, industrial users have become more and more More and more dissatisfied with RPM's current production capacity and prototype performance, and put forward higher requirements; Much improved and also presents a new challenge to RPM

Therefore, the limitations of RPM in terms of forming accuracy, efficiency, cost, materials, and prototype performance have become increasingly prominent, and have become the main bottleneck of this technology.
