【摘要】：從節(jié)省材料、增加穩(wěn)定性、填充支撐結(jié)構(gòu)等幾個(gè)方面對(duì)結(jié)構(gòu)進(jìn)行優(yōu)化,以及為了解決當(dāng)前一些有懸臂或者空腔結(jié)構(gòu)又不允許添加內(nèi)部支撐結(jié)構(gòu)的打印件無法制造的問題,設(shè)計(jì)出一種工作平臺(tái)可翻轉(zhuǎn)的3D打印機(jī),介紹了其結(jié)構(gòu)組成以及工作原理;利用ANSYS仿真軟件對(duì)系統(tǒng)建立仿真模型,得到工作平臺(tái)結(jié)構(gòu)和噴頭結(jié)構(gòu)的應(yīng)力分析,驗(yàn)證了設(shè)計(jì)方案的可行性,從而實(shí)現(xiàn)工作平臺(tái)可翻轉(zhuǎn)的可能性,完成無支撐結(jié)構(gòu)的曲面結(jié)構(gòu)打印以及對(duì)打印件結(jié)構(gòu)優(yōu)化設(shè)計(jì)。
[Abstract]:To optimize the structure from several aspects, such as saving material, increasing stability, filling support structure, etc., and in order to solve the problem that some printing parts with cantilever or cavity structure can not be manufactured without allowing the inside supporting structure to be added. A 3D printer with reversible working platform is designed and its structure and working principle are introduced. The simulation model of the system is established by using the ANSYS simulation software, and the stress analysis of the work platform structure and the nozzle structure is obtained. The feasibility of the design scheme is verified, and the possibility of the work platform flipping can be realized. Finish the printing of curved surface structure without support and optimize the structure of printed parts.
