This study aims to analyse the process conditions in the production of poly(lactic acid) (PLA) films by solvent-cast 3D printing. The films were evaluated according to thickness, roughness and visual aspect. An experimental design $$2^{{2}}$$ 2 2 was performed with centre point in triplicate to study solvent/PLA ratio and printing speed. The solvent/PLA ratio and printing speed had a significant negative effect on film thickness and positive effect on film roughness. The film that presented the best classification in the visual aspect was the one moulded with the highest printing speed and solvent/PLA ratio.

聚乳酸薄膜溶剂浇注3D打印质量评价

本研究旨在分析通过溶剂浇铸 3D 打印生产聚乳酸 (PLA) 薄膜的工艺条件。根据厚度、粗糙度和视觉方面评价膜。实验设计 $$2^{{2}}$$2 2 以中心点一式三份进行，以研究溶剂/PLA 比率和印刷速度。溶剂/PLA 比例和印刷速度对薄膜厚度有显着的负面影响，对薄膜粗糙度有积极的影响。在视觉方面呈现最佳分类的薄膜是具有最高印刷速度和溶剂/PLA比率的模塑薄膜。
