与大豆一起烹饪:立陶宛团队证明植物油可用于3D打印

一组研究人员考纳斯技术大学(KTU)和Vilnius University, Lithuania, have proved that a material based on cooking oil can be used for 3D printing.

该材料被称为Aeso(丙烯酸化的环氧化大豆油),该材料正在接受其替代石油衍生树脂的潜力的测试,并且已证明无需使用光吸剂而起作用。

该小组的最新实验已在线发布聚合物杂志。

无溶剂3D打印

在这项最新研究中,KTU/Vilnius团队使用定制的直接激光写作(DLW)光刻技术。像其他相关方法一样(即两个光子聚合) the DLW method harnesses the power and speed of femtosecond laser pulses to rapidly cure a liquid into a solid.

选择一个小的正方形晶格作为测试工件。总体而言,团队进行了三种不同的AESO混合物,以确定最佳公式,即:

– Pure AESO
- 带有香草素二甲基丙烯酸酯(VDM)的Aeso
- 与香草蛋白二丙酸酯(VDA)的Aeso

Both vanilla-based extracts, derived fromlignin, VDM and VDA were tested in this experiment as a replacement for the aromatic-compounds typically found in petroleum-based resins. As acrylates, both substances also have high light sensitivity which could boost polymerization.

增值税聚合的环境友好的未来

在此实验设置中,测试表明纯Aeso和Aeso/VDM适用于3D打印,而无需光启动器或溶剂。

Comparing the two however, conclusions add, “better thermal and mechanical properties were obtained for the pure AESO polymer.”

此外,“达到最小的空间特征是1 µm,每秒6900素的吞吐量为1 µm。”

总体而言,团队认为,这对于开发环保和可持续的聚合物的开发可能是迈出的一步。由于避免了有毒成分,可能的应用包括3D印刷细胞支架和纳米光子。
