Optimized Design And Research Of New Toner Laser 3D Printer

With the development of science and technology,3D printing technology is closely related to human life.In the manufacturing industry,3D printing technology has the characteristics of more convenient printing,more diverse materials,and more environmentally friendly manufacturing processes than traditional manufacturing processes.With the improvement of the level of 3D printing,there are more and more personalized demands.Therefore,in order to meet the needs of users for personalization and commercial use,a new type of three-dimensional toner laser printer was designed,the structure of main parts of the printer was optimized,the modular design was realized,and the corresponding finite element analysis And kinematics simulation,the specific research content of the paper is as follows:First,through theoretical analysis and market research,the design idea of the printer is clarified,the structure of the printer is determined,and the overall working part of the printer is divided into four functional modules,namely: laser emission system,imaging system,powder coating system,printing Platform system.Through the analysis of the printing speed and accuracy,the light source type of the laser emitting device is selected.According to the principle of lamp shadow imaging,two methods of imaging glass are proposed to solve the structure caused by the use of many parts in the imaging complex problems.In order to facilitate and realize the printing of multi-material or complex hollow structure,a new double-tube powder silo structure is proposed for the powder spreading system.A lifting platform system is designed to meet the printing needs.Secondly,the Solid Works software is used to establish the physical model of the printer,and the magnetic roller in the double-tube material powder silo is used as the standard to design the size and structure of the material powder silo of the printer.The parametric modeling function of the Creo software is used to construct the material powder silo gear.Complete the selection of the standard size of imaging glass and printing work platform.Again,in order to obtain the laser power value that can make the material powder reach the sintering condition,the thermal simulation analysis of the material powder is performed using ANSYS Workbench software.Because the laser used for sintering and curing will generate a lot of heat during operation,in order to ensure the safe operation of the equipment,the thermodynamic analysis of the mechanism to which the laser can be irradiated: in order to complete the design of the imaging system,thermal analysis of two imaging glasses;the printer The lifting work platform is used for thermodynamic analysis,and the worktable that can meet the printing temperature requirements is selected;then the printing material is sintered and solidified according to the printing material's melting point,density and other parameters.Finally,calculate the parameters of the drive device,select the appropriate printer drive motor;and select the belt drive as the printer drive method,determine the type of belt drive,and complete the selection of the belt type;complete the overall structure of the printer virtual prototype,and according to Printer virtual model,using Recur Dyn software for kinematics simulation analysis,to simulate the working process of the printer.
