微型螺杆挤出式3D打印机的研究进展

Research Development of Micro-Screw Extrusion 3D Printer

随着科学技术的不断进步,3D打印技术呈现快速多样化的发展趋势。通过分析3D打印的相关文献,发现3D打印技术存在打印耗材有限及传统3D打印机无压力堆积成型等主要缺陷,无法大规模替代传统制造技术,但与传统的制造技术相比,3D打印技术无论在材料的利用率、制品的复杂程度,还是在成型速度方面都具有突出的优势,所以要进一步扩大3D打印技术的应用,就要将其和传统制造技术结合起来,改变送丝液化的传统模式,形成1个新的发展增长点。通过分析近年来国内外学者将传统螺杆挤出技术应用于3D打印设备的几种典型实例,讨论了其优势与缺点,最后汇总了相关专利的申报情况,并对微型螺杆挤出式3D打印机的发展进行了展望。

With the continuous progress of science and technology, 3D printing technology presents rapid and diversified development. The main defects of the 3D printing technology were summarized through the analysis of relevant literature in recent years, such as limited printing supplied and 3D printer without pressure accumulation, so the traditional manufacturing technology can not be replaced by 3D printing on a large scale. However, compared with the traditional manufacturing technology, 3D printing technology in terms of material utilization, the complexity of the product, or in the molding speed has a prominent advantage. So it is important to combine traditional manufacturing technology with 3D printing, for expanding the application of 3D technology, and change the traditional mode of filament feed liquefaction to form a new growth point of development. Furthermore, several typical examples of the traditional screw extrusion technology applied to 3D printing equipment in recent years are mainly discribed, and its advantages and disadvantages are discussed. Finally, the applications of the related patents are summarized, and the development of micro-screw extrusion 3D printer is prospected.
