摘要
近年来随着科技的快速发展,3D打印技术也发展迅速,其中FDM型技术使用广泛。螺杆挤出机构有对塑料颗粒进行输送、熔融、共混、剪切等优点,其与3D打印喷头的结合拓宽了材料范围。本文介绍了FDM型3D打印螺杆挤出系统的发展,针对不同的喷头螺杆结构进行了分析,并对螺杆的选择与设计给出建议,最后探讨了螺杆挤出系统目前存在问题和其发展前景.
In recent years,with the rapid development of technology,3D printing technology has also developed rapidly,among which FDM technology is becoming increasingly widely used.The screw extrusion mechanism has advantages in conveying,melting,blending,and shearing plastic particles,and its combination with 3D printing nozzles broadens the material range.This article introduces the development of FDM type 3D printing screw extrusion system,analyzes different nozzle screw structures,provides suggestions for screw selection and design,and finally discusses the current problems and development prospects of screw extrusion system.
