A method for micro-fabricating a device on a substrate (), comprising the steps of providing a cavity () having a temporary aperture () communicating with the outside; providing a sealing structure () adjacent to a perimeter of the temporary aperture (); applying heat to the sealing structure (), whereby the sealing structure melts and seals the temporary aperture ().

Machining process for microfluidic and micromechanical devices

The present disclosure concerns a multi-spectral image printing method. The method includes the steps of:&#x2014;providing a multi-spectral image;&#x2014;providing a material;&#x2014;determining changes in a refractive index value of the material permitting to reproduce the multi-spectral image when the material is illuminated; and&#x2014;generating the changes in refractive index value in the material.

Multi-spectral image printing method

A method including the steps of exposing a substrate to focused laser irradiation at a preselected series of locations that trace a subset of the substrate volume that is connected to the surface of the substrate, removing the substrate material from the exposed preselected series of locations to create within the substrate at least one cavity that is connected to the surface of the substrate, immersing the cavity-containing substrate in an appropriate atmosphere such as a selected gas or vacuum and, within this atmosphere, contacting the substrate surface with the molten castable material surface at locations where the cavity or cavities emerges from the substrate, applying pressure to the castable material to cause it to infiltrate the substrate cavities, and solidifying the castable material within the cavities.
