Large scale construction in engineering includes many components.
- Cranes and scaffolding are needed to provide structure.
- This adds cost in terms of time, human labor, and machinery.
In contrast, in nature a very complex build uses a different paradigm, such as what a spider does when it builds a web.
- There are no scaffolds or cranes.
- In a web, proteins and signals interact with each other.
- This determines the eventual structure of the web.
During the construction of the web, a spider will eat the prey and digest it.
- It will then reorganize the prey it ate and break it down into its elementary amino acid building blocks.
- It then creates a new protein based on its DNA sequence
- By this process, it produces different kinds of silks that will be used to build its web.
Spiders can build 2D and 3D webs.
- By extracting spider silk filaments, experimentation can be done using spider silk to understand spider construction.
- Spiders building webs is an inspiration for 3D printing, as the spider can do more things than we can do in engineering.
- Using a sheet laser and slicing the web into thousands of pieces, webs can be scanned and then the photos used to reconstruct a 3D model.
