Abstract
3D printing has the characteristics of layer-by-layer manufacturing, which causes high surface roughness. This paper proposes a scheme to develop a printing protocol combining layer-wise and continuous printing based on the required surface roughness. It involves four modules: model slicing, printing pattern estimation, slices adjusting and printing protocol generation. Firstly, the candidate slices are obtained by model slicing based on the required surface roughness. Secondly, the printing pattern of each slice is estimated based on the max-min distance of the corresponding slice and Maximum Filled Distance (MFD) of the printing resin material. Then, the candidate slices are adjusted based on the maximum and minimum printable thickness of the printer. Finally, the printing protocol involving slice number, slice thickness, printing pattern and printing time is generated, and the surface roughness of the printed objects using the generated printing protocol can be estimated. Two printing protocols of the model cup with different required surface roughness are automatically generated. And two objects are printed based on the corresponding printing protocols. The roughness of the printed objects is measured using the roughness tester. The average roughness of the printed objects is smaller than the required roughness because the roughness of continuous printing is small. And the error between the measured and the predicted roughness is smaller than 2 µm.
3D打印具有逐层制造的特点,导致表面粗糙度很高。本文提出了一种基于所需表面粗糙度的分层和连续打印相结合的打印协议方案。它包括四个模块:模型切片、打印模式估计、切片调整和打印协议生成。首先,根据要求的表面粗糙度,通过模型切片获得候选切片;其次,根据相应切片的最大-最小距离和打印树脂材料的最大填充距离(Maximum fill distance, MFD)估计每个切片的打印图案;然后,根据打印机的最大和最小可打印厚度调整候选切片。最后,生成包含切片数、切片厚度、打印图案和打印时间的打印方案,并利用生成的打印方案对打印对象的表面粗糙度进行估计。自动生成两种不同表面粗糙度的模型杯打印方案。并根据相应的打印协议打印两个对象。使用粗糙度测试仪测量打印对象的粗糙度。由于连续打印的粗糙度较小,打印对象的平均粗糙度小于要求的粗糙度。测量值与预测值误差小于2µm。
