摘要
3D打印技术问世以来,在众多领域得到了广泛应用,但随着应用场景的精细化要求逐渐提高,对3D打印产品的打印质量也有了更高的要求。本研究针对UV光固化油墨3D打印技术,提出了一种模型表面质量改善的可行方法。运用UV油墨固化前的流动性,通过改变不同分层的打印顺序,以正序、完全倒序、分组倒序-2、分组倒序-4和分组倒序-9等5种方式打印分层设色地形图3D模型,并从模型的局部高清图及3D高度图、表面轮廓及斜率变化、基于模型顶视图的图像质量评价三个方面,分析不同打印顺序对同一模型表面质量产生的影响。结果表明,倒序打印能够改善模型固有的阶梯效应,保证模型的表面颜色呈现,提升UV光固化油墨3D打印模型的表面质量。
Since the advent of 3D printing technology,it has been widely used in many fields,but with the gradual increase of the refinement requirements of application scenarios,there are higher requirements for the printing quality of 3D printing products.In this study,a feasible method for model surface quality improvement was proposed for UV-cured ink 3D printing technology.Using the fluidity of UV ink before curing,by changing the printing sequence of layers,the layered colored terrain map 3D models were printed in five ways:positive sequence,complete reverse-sequence,reverse-sequence-2,reverse-sequence-4 and reverse-sequence-9.And the effects of the models with different printing sequences on the surface quality were analyzed from three aspects:local high definition image and 3D height image,the change of surface outline and gradient,and image quality evaluation based on the top view of the model.The results showed that reverse-sequence printing can improve the inherent staircase effect of the model,ensure the surface color rendering of the model,and improve the surface quality of the printing model for UV-cured ink 3D printing.
