This patent application claims the use of directed energy in the form of electronically scanned ion beams to form plastic parts by selectively curing commodity or engineering resin in the shape of the part. Polymerization is limited to the vicinity of the controlled Bragg-peak of the ion beam (i.e., where linear energy transfer is maximized), if necessary, by the use of chemical polymerization inhibitors or conditions that inhibit polymerization.

An ultrasonic probe and methods of manufacture are provided. The method can include depositing a base layer on a platform. The method can also include depositing a first portion of a first functional layer on the base layer. The method can further include positioning a first surface of an ultrasonic transducer on the first portion of the first functional layer. The transducer can further include a second surface opposite the first surface and opposed first and second sides. The first and second sides can be transverse to the first and second surfaces. The method can additionally include depositing a second portion of the first functional layer on the first and second sides of the transducer. The method can further include depositing a second functional layer upon the second surface of the transducer. The transducer can be encapsulated by the first functional layer and the second functional layer.

The present disclosure provides a method of making a ceramic article. The method includes (a) obtaining a photopolymerizable slurry or sol including a plurality of ceramic particles distributed in the photopolymerizable slurry or sol and (b) selectively polymerizing the photopolymerizable slurry or sol using actinic radiation and continuous movement of a build substrate through the photopolymerizable slurry or sol to form a gelled article. The method also includes (c) extracting solvent from the gelled article to form an aerogel article or a xerogel article; (d) heat treating the aerogel article or the xerogel article to form a porous ceramic article; and (e) sintering the porous ceramic article to form a sintered ceramic article. The sintered ceramic article exhibits a particular density. Further, additive manufactured ceramic articles are provided that exhibit a particular density, opacity, or both. Preferably, all cross-sectional portions of an interior of the ceramic article having selected dimensions are free of a frequency analysis signal maxima larger than a background signal.
