Optimization Design And Analysis Of Structural Parameters Of Ceramic 3D Printer

The application of ceramics is very broad,it involes many a lot of people's life,such as medical treatment?living and architecture,and it also plays a crucial role in the field of high-end research,such as the advanced ceramic materials with many advantageous properties are extremely needed in aerospace and national defense.3D printed ceramic products can not only guarantee great surface quality and good performance,but also save a lot of manpower and material resources,and it's more efficient and more economic.This paper is based on the existing ceramic printer structure,takes the parallel ceramic 3D printer which is designed by myself as the research object,optimizes the structure and analyzes it.First of all,this paper introduces the structure of existing 3D printing equipment on the market and the structural shortcomings of ceramic print heads at present,combines the ceramic printing with the pure Delta structure first time,designs a ceramic 3D printing device which is based on the Delta structure,analyzes the fluid state of the ceramic 3D printinig head by the software of Fluent,performs the simulation analysis between the rotary screw nozzle structure in this paper and the piston structure on the market,verifies the rationality and feasibility of the structure which is mentioned in this paper.The second,analyzes the kinematics of the ceramic 3D printer,deduces the obverse-inverse kinamatics and the velocity,acceleration equation,the mathematical model is simulated by software to prove the correctness of the obverse-inverse kinamatics equation.Once again,on the basis of kinematical analysis,optimizes the multi-objective problem of kinematics performance by multi-objective optimization algorithm and obtains a set of structure size which is optimal for the multiple objective functions by the software,multiple objective function values which is optimized are within a reasonable range,the mechanism has good operating performance.Then analyzes the printer by finite element software,we can find that the indicators of static,modal and harmonic response analysis are within a reasonable range,these indicators can satisfy the requirement of precision.Finally,analyzes the error of the printer.On the basis of the kinematics analysis that is mentioned in the foregoing,we can derive the precision mathematical models,substitute the structure parameters after the multi-objective optimization,combine software to carry out the simulation,the influence of the error on the accuracy of the printing terminal can be observed.
