Can you think of a way of performing soft lithography on curved surfaces like a glass optical fiber? Why would you want to do that?

Soft lithography is inherently a 2D printing technique, can you think of a way to taking to the third dimension? Why would this capability be useful?

Expert Solution

There are number of techniques of soft lithography
For E.g.
Micro Contact Prinitng : -
A polydimethyisloxane (PDMS) replica cast from am master is used as a stamp. An ink -such a solution of
CH₃(CH₂)₁₅SH in ethanol - is applied to the stamp using a cotton swab.
The inked stamp is then placed by hand onto a metal coated silicon substrate.
The stamps conforms to surface and a self assembled monolayer forms in the regions of contact between the stamp and the surface.
After 10-20s , the stamp is seperated from the substrate , leaving the monolayer on the surface.

There are number of ways of 3D printing like Polymer pen lithography , sterolithography etc.
This capability is useful because we have our objects in 3D therfore 3D printing is more better than 2D prinitng.
At the time, nearly all metalworking are produced by casting, fabrication, stamping, and machining; although plenty of automation was applied to those technologies (such as by robot welding and CNC)

Identify a “multicomponent, soft material” that you find interesting, and would like to discover how it works. To be acceptable, the material you choose must have a multicomponent formulation with non-trivial mechanical properties. 1. Identify the product or material. You can be as specific as you like – Crest pro-health, Kirkland signature natural peanut butter, “Great Stuff” rodent- blocking foam, whatever. 2. Identify the primary pupose of the product or material – what is it supposed to do, what problem is it...
