    摘要： 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.

    摘要： The invention includes a three-dimensional printing (3DP) machine that has at least one ultraviolet (UV) light source directed at powder or slurry being processed by the 3DP machine and/or directed at any of various surfaces or machine components, in a manner suitable to kill or damage microorganisms to a desired extent. The UV light sources may be either stationary or movable, and may be either pulsed or substantially continuous, and may operate in any desired sequence and timing with respect to other operations performed by the machine. The invention may include ultraviolet illumination in such a way as to interact with powder to sterilize or disinfect powder either while the powder is stationary or, alternatively, as powder is being moved from one place to another within the 3DP machine, or both. The invention also includes methods of performing three-dimensional printing using such illumination. The invention also includes the combination of other methods of sterilization or disinfection with the use of ultraviolet light. The invention also includes the use of ultraviolet light sources for a combination of polymerization/cross-linking in addition to sterilization/disinfection.

    摘要： A device for controlling or altering the temperature of a liquid at the point of dispensing. A temperature-altering device is thermally coupled to a dispensing device to compensate for heat dissipated into the liquid as it passes through the dispensing device during dispensing. The dispensing device may be for example, a miniature solenoid valve (microvalve), a piezoelectric printhead, or the like. According to aspects of the invention, a temperature-altering device provides or reduces heat at the point of dispensing in order to alter, control or maintain a constant temperature of the dispensed liquid. As a result, improvement is obtained in the consistency of the fluid regime of the dispensed droplet stream. The temperature-altering device may be a thermoelectric device capable of moving heat either from or to the dispensing structure, or may be a heater. This device may be used beneficially even when the dispensing is performed near room temperature and the liquid does not require heating to maintain its liquid state.

    摘要： The invention includes a heat transfer geometry having first and second flow channels in parallel with each other. The flow cross-sectional area of individual channels varies along the length of the flowpath, with one channel undergoing an expansion and the other undergoing a contraction. Different amounts of additional heat transfer surface are located within different regions. In at least some instances, contraction and expansion may occur as a result of a shift of both the left and right boundaries which principally define the channel, and may occur symmetrically with respect to a centerline of the individual channel. With a cell being a first channel and associated second channel, the overall exiting flow may be offset slightly from the overall entering flow. An array may be formed containing multiple cells, and cells at edges of the array may be atypical so that the overall array fits within a simple geometric envelope.
