Continuous additive manufacturing apparatus
Continuous additive manufacturing apparatuses are provided. An apparatus includes an actinic radiation-transparent substrate having a major surface and an irradiation source configured to direct actinic radiation through the actinic radiation-transparent substrate at predetermined dosages at predetermined locations. The apparatus further includes a means for depositing a composition onto the major surface of the actinic radiation-transparent substrate and a means for conveying the actinic radiation-transparent substrate or the irradiation source with respect to each other.
1. An apparatus comprising:
an actinic radiation-transparent substrate having a major surface;
an irradiation source configured to direct actinic radiation through the actinic radiation-transparent substrate at more than one predetermined dosage at more than one predetermined location;
a means for depositing a composition onto the major surface of the actinic radiation-transparent substrate, wherein the substrate is in a form of a cylinder and the means for depositing consists of rotating the cylinder through a volume of the composition held in an open container to apply the composition on the substrate without additional components for controlling a thickness of the composition on the actinic radiation-transparent substrate; and
a means for conveying the actinic radiation-transparent substrate and/or the irradiation source with respect to each other.
2. The apparatus of claim 1 , further comprising an air knife configured to remove the composition from the substrate, the irradiation source disposed between the means for depositing and the air knife.
3. The apparatus of claim 1 , wherein the substrate comprises a release material coated on the substrate.
4. The apparatus of claim 1 , further comprising a second substrate.
5. The apparatus of claim 4 , wherein the second substrate comprises a structured sheet.
6. The apparatus of claim 1 , further comprising a robot configured to remove a plurality of adhesives from the substrate.
7. The apparatus of claim 1 , wherein the substrate comprises glass or a polymeric material.
8. The apparatus of claim 1 , wherein the actinic radiation-transparent substrate comprises a polymeric material selected from polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyimide, cycloolefin films, poly(methyl methacrylate), or combinations thereof.
9. The apparatus of claim 1 , wherein the actinic radiation is provided by a digital light projector (DLP) with a light emitting diode (LED), a DLP with a lamp, a laser scanning device with a laser, a liquid crystal display (LCD) panel with a backlight, a photomask with a lamp, or a photomask with an LED.
