Solution-curing quick-molding manufacturing method

Abstract

The invention discloses a solution-curing quick-molding manufacturing method which comprises the following steps: preparing a raw solution material; carrying out program cutting and layering on a to-be-formed product by virtue of a computer; controlling the start and stop of a pump, the flow rate of the pump and the motion track of a printing sprayer by virtue of the computer, so that chemical or physical change occurs during the contact of the raw solution material and coagulating bath and the raw solution material is cured and formed; controlling a liftable work platform to descend to the height which is the same as the thickness of a virtual layer after printing of a physical layer is completed; repeating the previous step until all the physical layers corresponding to the virtual layers are printed. According to the method, the raw solution material is uses as a raw material for rapid material increasing manufacturing; the raw material scope of rapid material increasing manufacturing is widened; the production method of rapid material increasing manufacturing techniques is enriched; meanwhile, during the producing and manufacturing process of the solution-curing quick-molding manufacturing method, no heating device such as a high energy laser is needed; the production process is low in energy consumption and easy to control; the device is relatively simple; the method can be easily used in large-scale application.

Description

technical field [0001] The invention relates to a rapid additive manufacturing method, in particular to a solution solidification rapid prototyping manufacturing method. Background technique [0002] Rapid additive manufacturing technology (also known as 3D printing technology) is a technology that has received widespread attention in recent years. It uses 3D CAD data to accumulate layers of materials into solid prototypes by various means. The main methods are fused deposition technology (FDM), selective laser melting (SLM) or selective laser sintering (SLS), gypsum 3DP printing technology, etc. The raw materials for printing are generally filamentous, powdery metal or non-metallic , light-cured liquid resin, etc. [0003] Stereolithography (SL) technology is based on the polymerization reaction of photosensitive resin, and the ultraviolet laser under computer control scans the liquid resin point by point along the outline of each layered section of the component, so that ...

AI Technical Summary

Problems solved by technology

[0005] Since the materials used in the existing rapid additive manufacturing technology are generally filamentous, powdery metal or non-metal, light-cured liquid resin, etc., these materials generally require laser or other equipment to be heated during the curing molding process. Therefore, the existing additive manufacturing technology has disadvantages such as large energy consumption, complex equipment structure, and high difficulty in control; at the same time, there is no rapid additive manufacturing technology using solution as raw material in the existing technology, and the additive manufacturing technology method is not enough. comprehensive
