Abstract
A method is disclosed of three-dimensional (3D) free-form printing for coating free-form objects, the method including: arranging a free-form object in a Langmuir-Blodgett (LB) trough filed with a liquid, the LB trough designed based on a shape of the free-form object; arranging an LB film comprising a plurality of colloidal nanospheres on a surface of the liquid within the LB trough; and draining the liquid from the LB trough to form a self-assemble film of the colloidal nanoparticles on a surface of the free-form object.

A method of three-dimensional (3D) free-form printing for coating free-form objects, the method comprising:
- arranging a free-form object in a Langmuir-Blodgett (LB) trough filed with a liquid, the LB trough designed based on a shape of the free-form object;
- arranging an LB film comprising a plurality of colloidal nanospheres on a surface of the liquid within the LB trough;
- and
- draining the liquid from the LB trough to form a self-assemble film of the colloidal nanoparticles on a surface of the free-form object.
A Langmuir-Blodgett (LB) trough, the LB trough comprising:
- a drainage basin having a radius R′(z)=r(z)+R(z), and wherein r(z) is a radius of a free-form object to be coated and R(z) is a radial distance between the free-form object to be coated and the drainage basin.
