摘　　要：快速成形技术在组织支架、药物给送系统方面的应用越来越广泛。针对快速成形可重复制造技术,探讨使用三维造型补偿技术解决快速成形过程中成形误差不一致问题。设计具有典型尺寸特征的标准试验件,并使用快速成形设备成形,对X、Y、Z三个方向的成形尺寸进行测量,综合探讨三维打印快速成形精度的影响因素。结果表明:三维造型补偿技术对模型成形过程产生的制造误差能够有效控制,成形误差一致性达90%以上,为工件的可重复制造提供了有效的解决方法。Rapid forming technology is more and more widely used in tissue scaffold and drug feeding systems. In this paper, 3-D model- ing size compensation technology was used to reduce rapid forming tolerance and solve the problem of tolerance inconsistency with re- spect to repeatable manufacturing technology. The typical experi- mental work piece was designed and was made by using an ultraviolet curing machine. The work-piece contains different kinds of size char acters in three directions of X, Y, and Z. These character sizes were measured with the factors affecting forming accuracies synthetically analyzed. The results show that the 3-D modeling size compensation technology can effectively control forming accuracies, with the toler- ance consistency being increased to 90% and above.
