新的研究细节产前开发对添加剂制造设计的影响

英国伯明翰大学的研究人员提出了一种新的设计方法,以实现添加剂制造,这表明从人类婴儿的产前发育中有很多东西可以学习。

伯明翰的作品工程学院and theCentre for Human Reproductive Science并出版国际高级制造技术杂志highlights how developing biological systems, tissues and organs, are built up incrementally via the division and replication of cells.

产前开发对添加剂制造的影响

The study notes both growth rate and region of growth change during pregnancy. Conversely, in additive manufacturing, the development or “growth” of a 3D printed part is solely reliant on the spatial domain, determined only by where the filament is deposited. In this regard, the temporal dimension (aka time) is an inoperative process variable when it comes to design for additive manufacturing. The study explores how an implementation of the temporal domain could lead to the development of previously unseen material properties and structures.

以前,研究人员试图改变3D印刷材料的性能,但它已经通过spatial variation of the composition of the deposited material,遗漏了时间域。这也将研究材料限制在多物质复合材料中。本研究的方法可以应用于单材料丝。

What do the researchers say?

主要研究员,机械工程系的劳伦·托马斯·塞尔(Lauren Thomas-Seale)博士指出:“尽管我们将其称为增材制造业,但传统上工程师学会根据悠久的减法制造历史来设计零件。这导致了设计创造力的限制。如果要在设计和基本技术中发挥全部潜力,则必须摆脱这种惯性。”

该研究的合着者,代谢与系统研究所的杰克逊·柯克曼·布朗博士补充说:“虽然在工程设计中使用生物学灵感却很普遍,但研究人类的成长并将其转化为先进的制造系统提供了全新看法。生物系统从逐步添加细胞到形成组织和器官的生物系统发展的方式,这些组织和器官相互生长和调节以在协同作用中起作用,是复杂的加性制造的缩影。”

这项由皇家学会资助的研究被命名为“添加剂制造的时间设计’. It is co-authored by Saliba, S., Kirkman-Brown, J.C. & Thomas-Seale, L.E.J..
