【摘要】：桌面3D打印技术已得到社会认可,而针对工业级大型3D打印技术的研究很少。工业级熔体微分3D打印技术,采用螺杆塑化熔融方式,具有更大的成型尺寸;可加入颗粒状聚合物,拓宽3D打印耗材种类;使用3 mm大喷嘴,有效提高打印速度。该工业级熔体微分3D打印技术中各个打印参数(如层高、喷嘴直径等)设置对于制品成型及制品力学性能有着至关重要的影响。将不同基材的玻纤复合材料作为研究对象,运用自主搭建的工业级熔体微分3D打印实验平台,研究不同打印参数下制品成型效果。通过SEM电镜图、TGA热重分析仪、DSC差示扫描量热法、拉力测试仪对制品及原材料进行分析。文章验证了该新型工业级熔体微分3D打印机对玻纤复合材料制备大型3D打印制品的可行性,且可以为工业级大型3D打印技术的发展提供理论基础和技术指导。
[Abstract]:Desktop 3D printing technology has been recognized by society, but little research has been done on industrial scale 3D printing technology. Industrial grade melt differential 3D printing technology, adopting screw plasticizing and melting mode, has larger molding size; can add granular polymer, widen the variety of 3D printing consumables; use 3 mm large nozzle to improve printing speed effectively. The setting of printing parameters (such as layer height, nozzle diameter, etc.) in the industrial melt differential 3D printing technology plays an important role in the molding and mechanical properties of the products. The glass fiber composites with different substrates were used as the research object and the experimental platform of industrial grade melt differential 3D printing was used to study the molding effect of the products with different printing parameters. The products and raw materials were analyzed by SEM thermogravimetric analyzer (TGA) by differential scanning calorimetry (DSC) and tension tester. This paper verifies the feasibility of the new industrial grade melt differential 3D printer for the preparation of large scale 3D printing products by glass fiber composites, and can provide theoretical basis and technical guidance for the development of industrial grade large-scale 3D printing technology.
