ULTRAVIOLET CURABLE EPOXY DIELECTRIC INK

A method of fabricating a three-dimensional (3D) object includes atomizing a pre-polymer composition into an aerosol jet stream. The pre-polymer composition includes an epoxy precursor and a photoacid generator. The method further includes depositing the aerosol jet stream onto a substrate to form a...

Zusammenfassung:	A method of fabricating a three-dimensional (3D) object includes atomizing a pre-polymer composition into an aerosol jet stream. The pre-polymer composition includes an epoxy precursor and a photoacid generator. The method further includes depositing the aerosol jet stream onto a substrate to form a first layer of dielectric ink and curing the first layer of dielectric ink using ultraviolet (UV) light. The method further includes depositing the aerosol jet stream onto the first layer of dielectric ink to form a second layer of dielectric ink. The first layer of dielectric ink and the second layer of dielectric ink overlap by at least 50%.
