摘要
盆景是中国和日本的一种古典艺术。传统的微型树木盆景造型方法技术性强,通常需要经验丰富的园艺师才能成功完成。为了让普通人也能感受到盆景塑形的乐趣,本文提出了一种快速盆景塑形方法,即使用定制形状的塑料导向模具,通过熔融沉积 3D 打印技术加工而成。树苗被捆绑在模具上,模具的形状引导树苗生长,从而达到盆景造型的目的。为了进一步提高盆景导向模具的弯曲性能,本文对 ABS 长丝的主要 3D 打印参数进行了研究。结果表明,随着打印速度的降低、挤出温度的升高和热床温度的升高,ABS试样的弯曲强度和弹性模量增加,弯曲性能增强;最佳打印速度为50 mm/s,挤出温度为230 ℃,热床温度为80 ℃。根据最佳工艺参数制造的盆景导向模的机械性能更好,打印质量更高,具有很高的实用价值。
Fused deposition 3D printing of bonsai tree guiding mold based on acrylonitrile-butadiene-styrene copolymer
Bonsai is a kind of classical art in China and Japan. The traditional method of bonsai shaping of miniature trees is technical and usually requires experienced horticulturists to successfully carry out the process. In order to let ordinary people feel the fun of bonsai shaping, this paper proposes a fast bonsai shaping method, i.e., by use of a plastic guiding mold with customized shape, which is processed by fused deposition 3D printing technology. The tree seedling is bundled onto the mold, and the shape of the mold guides the growth of the tree seedling, thus achieving the purpose of bonsai shaping. In order to further improve the bending properties of the bonsai guiding mold, this paper investigated the main 3D printing parameters of ABS filament. The results showed that with the decrease of printing speed, the increase of extrusion temperature, and the increase of hot bed temperature, the bending strength and elastic modulus of ABS specimens increased, and the bending properties was enhanced; the optimal printing speed was 50 mm/s, the extrusion temperature was 230 °C, and the hot bed temperature was 80 °C. The mechanical properties of the bonsai guiding mold manufactured based on the optimal process parameters were better, the print quality was higher, and it had high practical value.
