Nature combines stiff and strong collagen fibres intertwined within a weak polymer matrix of proteoglycans into soft tissues with outstanding mechanical durability and biological properties. We converge a biomimetic design strategy inspired in the architecture of natural soft tissues and a novel additive manufacturing technology termed melt electrowriting (MEW) to manufacture advanced biomimetic soft network composites (BSNC). The SNCs are composed of a weak polymer matrix and a MEW reinforcing fibrous phase printed at the nanometre scale, containing patterns mimicking the natural tissue architectures. Advanced computational tools are applied for the rational design of the SNC while reducing costs and times associated to experimental work.

大自然将坚硬而坚固的胶原纤维交织在蛋白聚糖的弱聚合物基质中，形成具有出色机械耐久性和生物学特性的软组织。我们融合了一种仿生设计策略，灵感来自天然软组织的结构和一种新的增材制造技术，称为熔融电写入（MEW），以制造先进的仿生软网络复合材料（BSNC）。SNCs由弱聚合物基质和纳米级印刷的MEW增强纤维相组成，包含模仿天然组织结构的图案。先进的计算工具被应用于SNC的合理设计，同时降低了与实验工作相关的成本和时间。
