Abstract: A self-supporting aerogel structure is provided. The structure comprises a plurality of aerogel particles adhered together with an adhesive to produce a material exhibiting low heat transfer and high transmission of visible light. The aerogel particles can be coated with a polymer or pre-polymer and remain free flowing until they are activated to complete polymerization.

Abstract: A uniaxially compressed dosage form manufactured by three-dimensional printing that preserves the predetermined internal architecture of the dosage form while producing an improved surface finish. The compression compacts the dosage form, eliminating at least some of the void space that remains at the end of conventional three-dimensional printing. Surface finish obtained as a result of the uniaxial compression process can be essentially equal to that obtained from conventional tablet pressing. Additionally, the internal structure or spatial variation of composition of the dosage form is preserved during the pressing operation, with geometric shrinkage occurring mostly in the direction of the axis of pressing. Further, as a result of compression, a greater quantity of API can be packed into a given final volume of dosage form.

Abstract: The present invention includes controlled release dosage forms and methods of designing and manufacturing dosage forms to obtain specific release profiles, for example, zero-order release profiles, escalating release profiles or decreasing release profiles. The dosage forms of the present invention can include spatial variation of API concentration in the dosage form and can include nested regions. Dosage forms according to the present invention may be manufactured by any appropriate method for obtaining the internal structure as disclosed herein for producing zero-order release profiles and increasing or decreasing release profiles. The invention further includes methods of manufacturing such dosage forms, such as by three-dimensional printing, possibly also including compression of the dosage form after three-dimensional printing. The invention further includes methods of designing such dosage forms.

Abstract: The invention includes dispensing a suspension containing solid particles for use in manufacturing a dosage form or other biomedical article by 3DP. The suspension contains solid particles suspended in a liquid. The solid particles may be one or more Active Pharmaceutical Ingredients. The solid particles may be particles of material that are insoluble in the liquid, or they may be particles of a substance that have already dissolved in the liquid up to the saturation level and are present in a concentration beyond what can be dissolved. In addition to solid particles, the liquid may also contain other substances dissolved in it, either substances containing Active Pharmaceutical Ingredients (API) or substances without API. One aspect of the invention includes prevention of agglomeration by adding one or more of several categories of additives to the suspending liquid.

Abstract: A method and apparatus for controlling the migration of binder liquid in a bulk powder. The bulk powder may be deposited in a powder bed and contains at least two different substances, each in powder form. One substance gives the printed part its bulk properties, forms most of the powder, and preferably is either insoluble or not significantly soluble in the binder liquid. The other powder substance is a migration control substance. Upon interaction with the binder liquid, this substance may absorb the binder liquid and form a gel or dissolve into the binder liquid increasing viscosity thereby inhibiting binder migration. No chemical reactions occur between the binder liquid and any of the substances in the powder bed. In another embodiment of the instant invention, binder migration may be further controlled by first printing a barrier region in the powder bed containing the migration control substance.
