To better control part quality of 3D printed parts, the temperature of an extruder filament using a secondary heat source is provided. A heat source, such as an infrared heat source, can be used to heat the filament of a 3D printer to the optimum temperature that will enhance welding of the filament to a substrate that it is being printed on or to. Such an optimum temperature can be based upon, in part, the temperature of the substrate. A controller or other intelligent control can be used to receive temperature readings of the substrate and/or filament and then can adjust the temperature of the heating source to optimize the temperature of the filament to better combine the filament to the substrate.

An apparatus for supporting a workpiece having high versatility that can address a plurality of types of workpieces is achieved. An apparatus for supporting a workpiece according to one embodiment of the present disclosure includes a resin part configured to support the workpiece, the resin part being softened when it is heated to a predetermined first temperature or higher in an initial shape, cured when it is cooled down to a temperature lower than a predetermined second temperature from the state in which it is softened, and softened while it is restored to the initial shape when it is heated again to the first temperature or higher; a temperature adjustment part configured to adjust the temperature of the resin part; and a controller configured to control the temperature adjustment part.

A method of manufacturing a sealed circuit card assembly includes disposing a circuit card assembly within a volume defined by a housing and at least partially filling the volume with a curable liquid such that the curable liquid encapsulates at least a circuit card. The method may also include curing the curable liquid to form a potted circuit card assembly and, after at least partially filling the volume with the curable liquid and after curing the curable liquid, vacuum impregnating the potted circuit card assembly with a sealant to seal any exposed interfaces or cracks to form the sealed circuit card assembly. Accordingly, the sealed circuit card assembly may include a first cured material encapsulating the circuit card of the circuit card assembly and a second cured material disposed within, for example, a porosity of the first cured material.

A tubular body (1) made of a fiber-reinforced plastic and used as a structural material of a vehicle includes corners (4) extending along an axis of the tubular body (1) on an outer circumferential surface thereof. The tubular body (1) is a tubular laminate that is formed by laminating a fabric layer (12) formed by laminating fabric materials and unidirectional material layers (11, 13). Each fabric material includes a fabric in which reinforcing fibers are woven and a plastic with which the fabric is impregnated. Each unidirectional material layer (11, 13) includes reinforcing fibers oriented in one direction and a plastic with which the reinforcing fibers are impregnated. The reinforcing fibers of each unidirectional material layer (11, 13) are oriented along the axis of the tubular laminate. The unidirectional material layers (11, 13) include an outer unidirectional material layer (13) laminated on an outer circumferential surface of the fabric layer (12), and an inner unidirectional material layer (11) laminated on an inner circumferential surface of the fabric layer.

Methods systems and apparatuses for reducing or substantially eliminating distortion in a transparent substrate in situ are disclosed.

An imprint apparatus for forming a pattern of an imprint material on a substrate using a mold includes a heating unit, a generation unit, and a measurement unit. The heating unit irradiates a region to be processed on the substrate with light to heat the region to be processed. The generation unit generates irradiation amount distribution data, which indicates an irradiation amount distribution of light with which the heating unit is to irradiate the region to be processed. The measurement unit measures information about absorption of the light by the region to be processed. The generation unit generates the irradiation amount distribution data by correcting, using a result of measurement by the measurement unit, temporary irradiation amount distribution data temporarily generated based on a shape of the region to be processed taken before the region to be processed is heated by the heating unit.

A shaping apparatus includes a storage section that stores in advance a first relationship between a temperature of a shaping material and a heating time at a time at which oxidation of the shaping material starts as the shaping material is heated; and a control section that estimates a timing at which the oxidation of a material layer starts, based on an acquisition result from a temperature acquisition section, a measurement result from a time measurement section, and the first relationship stored in the storage section when the material layer on a conveyance body is preheated by a preheating section, and reduces a front surface temperature of the material layer on the conveyance body before the oxidation of the material layer starts.

A tool (100) comprises a plurality of layers (102, 104, 106) which are arranged to provide a thermally agile tool face (110) and to protect control circuitry and delicate components (150) from excessive temperatures.

A method of curing a composite layup may include applying an inner bag vacuum pressure to an inner bag chamber and an outer vacuum pressure to an outer vacuum chamber. The vacuum inner bag chamber may be formed by a vacuum bag covering a composite layup and sealed to a forming tool with an inner bag chamber seal. The inner bag vacuum pressure may be no less than the outer vacuum pressure. The temperature of the composite layup may be increased to an elevated temperature to initiate a temperature hold period. The method may additionally include venting the outer vacuum chamber to atmosphere to initiate an outer vacuum chamber venting period during the temperature hold period, and applying compaction pressure to the inner bag chamber seal during the outer vacuum chamber venting period. The outer vacuum pressure may be re-applied to the outer vacuum chamber to terminate the outer vacuum chamber venting period.
