Abstract
A rapidly printing 3D nanostructures arrangement, comprising a first photonic source configured to provide photoinitiation energy to a polymer medium via a dynamic light spatial modulator to an excited state to initiate polymerization, a second photonic source configured to selectively provide inhibition energy to the polymerized medium to a depleted state to inhibit polymerization thereby generating a dead zone below a growth zone, the dead zone allows continuous 3D polymerization.
Claims4
A rapidly printing 3D nano structures arrangement, comprising:
- a first photonic source configured to provide photoinitiation energy to a polymer medium via a dynamic light spatial modulation member that directs the photoinitiation energy through a focusing device included on a window, wherein the focusing device projects a photo initiation beam onto the polymer medium and brings the polymer medium to an excited state to initiate polymerization;
- and
- a second photonic source configured to selectively provide nanoscale light energy confinement and light intensity enhancement to provide inhibition energy to the polymerized medium,
- wherein an inhibition beam from the second photo light source is directed through the window without passing through the focusing device included on the window, wherein the inhibition beam brings the polymer medium to a depleted state to inhibit polymerization thereby generating a nanoscale dead zone below a growth zone,
- wherein the dead zone allows continuous 3D polymerization, wherein the dead zone forms a surface plasmonic field.
