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打印可实现高速，高分辨率的复杂或定制结构的生产。但是，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重大障碍，限制了3D打印在产品制造中的广泛采用。用于3D打印技术的生态友好型天然生物聚合物的开发及其在不同领域中的有希望的应用具有巨大的学术和环境利益。本文回顾了使用天然来源的原料（包括木质纤维素，淀粉，藻类和壳聚糖基生物聚合物）进行的3D打印技术的最新发展。特别考虑开发木质纤维素材料，即纤维素，半纤维素，木质素及其衍生物作为3D打印原料。提出了战略发展路线图，其中确定了材料特性要求，关键挑战以及可能的解决方案。它作为指南，旨在探索天然来源的生物聚合物，将其作为可用于各个领域的不同3D打印技术的新型原料。
