Abstract: Methods provide for fabricating objects through additive manufacturing in a manner that compensates for deformations introduced during post-print processing, such as sintering. An initial model may be divided into a plurality of segments, the initial model defining geometry of an object. For each of the segments, modified geometry may be calculated, where the modified geometry compensates for a predicted deformation. Print parameters can then be updated to incorporate the modified geometry, where the print parameters define geometry of the printed object (e.g., configuration settings of the printer, a tool path, an object model). The object may then be printed based on the updated print parameters.

Abstract: Complexity of a geometry of a desired (i.e., target) three-dimensional (3D) object being produced by an additive manufacturing system, as well as atypical behavior of the processes employed by such a system, pose challenges for producing a final version of the desired 3D object with fidelity relative to the desired object. An example embodiment enables such challenges to be overcome as a function of feedback to enable the final version to be produced with fidelity. The feedback may be at least one value that is associated with at least one characteristic of a printed object following processing of the printed object. Such feedback may be obtained as part of a calibration process of the 3D printing system or as part of an operational process of the 3D printing system.

Abstract: Methods of printing an object via a 3-dimensional printer include provide for printed objects having a higher density. A printer head is operated to deposit build material in lines under controlled parameters including lateral position, height, extrustion rate, extrusion temperature, and/or extrusion material. The printer may print first lines forming channels at a given layer, and then second lines to fill those channels. The printer may operate with other approaches to fill gaps between printed lines, such as offset and/or smaller lines aligned with those gaps. The resulting object has greater density while maintaining an accurate object shape.

Abstract: The present disclosure describes systems and apparatus for detecting an impending sewer backup by detecting fluid undulations of predetermined magnitude inside a main body of a backwater valve. When at least a predetermined number of fluid undulations of predetermined magnitude are detected within a predetermined time period, an alarm can be triggered. Such undulations can be detected by monitoring a buoyant gate in a normally-open backwater valve to detecting instances of movement of the gate from a lowered position in which fluid flow from an inlet through the backwater valve is unobstructed by the gate toward but stopping short of a raised position in which the gate closes the inlet to obstruct fluid flow through the valve. For example, a sensor can be carried on the gate to detect movement of the gate. Alternatively, fluid levels inside the main body can be monitored directly.

Abstract: Methods and apparatuses for manipulating the temperature of a surface are provided. Devices of the present disclosure may include a thermal adjustment apparatus, such as a controller in electrical communication with one or more thermoelectric materials, placed adjacent to the surface of skin. The device may generate a series of thermal pulses at the surface, for providing an enhanced thermal sensation for a user. The thermal pulses may be characterized by temperature reversibility, where each pulse includes an initial temperature adjustment, followed by a return temperature adjustment, over a short period of time (e.g., less than 120 seconds). The average rate of temperature change upon initiation and upon return may be between about 0.100/sec and about 1 OOC/sec. In some cases, the average rate of the initial temperature adjustment is greater in magnitude than the average rate of the return temperature adjustment.
