Abstract
This paper shows that a spider is a spinning master and a printing expert as
well. Firstly, a spider can produce different types of silks by controlling
the spinning process, which is correlated with silk properties.
Understanding the natural spinning process can greatly help for the
improvement of artificial spinning processes to control the products?
quality. Here we show the periodic motion of muscles connected to the
spinnerets plays an important role in controlling the spinning process and
the silk properties, which leads to a zero resistance of the viscous flow in
the gland duct and ordered macromolecules in the silk. We anticipate this
finding can promote a sophisticated study of other animals? spinning
properties and bio-inspired design of artificial spinning processes.
Secondly, the spider web is not weaved, but it is printed, the process is
similar to the modern 3-D printing technology. Finally, a spider-inspired
4-D printing technology is suggested.
