【摘要】 简单介绍了3D打印技术的历史发展状况。通过分析和论述了现在3D打印送粉器技术在国内外的研究和发展情况,知道国内外的发展还有一定的差距。并且还重点指出了目前3D打印送粉器技术存在着粉末利用率低、材料的限制和送粉不均匀等问题以及提出了可能解决问题的方法。在此基础上,还对3D打印技术未来的发展趋势进行了概括。更多还原

【Abstract】 Three dimensional( 3 D) printing technology of historistic development status was briefly introduced. Through the analysis and discussion of the powder feeder nowadays 3 D printing technology of research and development at home and abroad,between domestic and international development known,there was still a gap. And also it was highlighted the current 3 D printing powder feeder technology that there was low utilization rate of the powder,the powder feeding uneven,materials restrictions and other issues,and put forward possible solutions to the problem. On this basis,on the future of 3 D printing technology of development trends have been summarized.更多还原
