3D printing enables the complex or customized structures production in high speed and resolution. However, the lack of bio-based materials with user-defined biochemical and mechanical property is a significant barrier that limits the widespread adoption of 3D printing for products fabrication. Development of eco-friendly natural-derived biopolymers for 3D printing technologies and their promising application in different areas are of huge academic, and environmental interests. This paper reviews the state-of-the-art in terms of 3D printing technology using natural-derived feedstocks, including lignocellulose, starch, algae, and chitosan-based biopolymers. Special consideration is given to the development of lignocellulosic materials, i.e. cellulose, hemicellulose, lignin, and their derivatives as 3D printing feedstocks. A strategical development roadmap with identified material property requirements, key challenges, as well as possible solutions was proposed. It serves as guideline aiming to explore natural-derived biopolymers as novel feedstocks for different 3D printing technologies that will be potentially applied in various areas.
3D 打印能够高速、高分辨率地制造复杂或定制化的结构。然而，缺乏具有用户定义的生化和机械性能的生物基材料是一个显著的障碍，限制了 3D 打印在产品制造中的广泛应用。开发用于 3D 打印技术的环保型天然衍生生物聚合物及其在不同领域的有前途的应用具有巨大的学术和环境利益。本文综述了使用天然衍生原料进行 3D 打印技术的最新进展，包括木质纤维素、淀粉、藻类和壳聚糖基生物聚合物。特别考虑了将木质纤维素材料，即纤维素、半纤维素、木质素及其衍生物，开发为 3D 打印原料。提出了具有明确材料性能要求、关键挑战以及可能解决方案的战略发展路线图。它旨在探索天然衍生生物聚合物作为不同 3D 打印技术的新型原料，这些技术将有可能应用于各个领域。
