3D printing is a revolutionary additive manufacturing method that enables rapid prototyping and design flexibility. A variety of thermoplastic polymers can be used in printing. As it is necessary to reduce the consumption of petrochemical resources, alternative solutions are being researched, and the interest in using bioplastics and biocomposites is constantly growing. Often, however, the properties of biopolymers are insufficient and need to be improved to compete with petroleum-based plastics. The paper aims to analyze the available information on elements produced from more than one material, with additive manufacturing resulting from 3D printing using biopolymer Polylactic Acid (PLA). The study notes the possibility of modifying and improving the properties of PLA using layered printing or by modifying PLA filaments. Several modifications improving and changing the properties of PLA were also noted, including printing parameters when combined with other materials: process temperatures, filling, and surface development for various sample geometries.
3D打印是一种革命性的增材制造方法，它能够实现快速成型和设计灵活性。多种热塑性聚合物可用于打印。由于有必要减少石化资源的消耗，人们正在研究替代解决方案，并且使用生物塑料和生物复合材料的兴趣也在不断增长。然而，生物聚合物的性能往往不足，需要加以改进才能与石油基塑料竞争。本文旨在分析有关由多种材料制成的部件的现有信息，这些部件是使用生物聚合物聚乳酸（PLA）通过3D打印进行增材制造而成的。该研究指出了通过分层打印或改性PLA长丝来改性和改善PLA性能的可能性。还提到了几种改善和改变PLA性能的改性方法，包括与其他材料结合时的打印参数：工艺温度、填充以及各种样品几何形状的表面处理。
