A powder pressing plate assembly includes a pressing plate having a plurality of pressing tools and at least one etched plate attached to a pressing tool face of at least one of the plurality of pressing tools. The etched plate includes a design that may be embossed into a substrate. The design may be computer generated and then transferred to the etched plate via a solvent-less thermal exposure process, exposure to certain solvents used to wash away unwanted material, or built up using a three-dimensional printing or additive manufacturing process.

A method of separating a template from a cured layer on a substrate. Including, sending instructions to move the template away from the cured layer at a first rate, at a second point in time. Including, receiving a first data set as a function of time starting after the second point in time. Including, fitting a model of the first data set to a database of historical data sets. Including, identifying a target data set in the historical data sets based on results of the fit of the model of the first data set and information in the target data set. Including, sending instructions to move the template away from the substrate at a second rate at a third point in time after the second point in time based on the identified target data set.

A forming apparatus includes a substrate holder having a plurality of chucking regions that chuck a lower surface of the substrate and configured to hold the substrate by chucking the substrate with the plurality of chucking regions, and a controller configured to control execution of a forming process and independently control a chucking force of each of the plurality of chucking regions. The controller controls a chucking force of each of the plurality of chucking regions in a mold separation step so as to make a final mold separation point, at which the mold finally separates from the composition, coincide with a center of a pattern surface of the mold.

A template and a template blank are used for imprint lithography transferring a transfer pattern in a concave and convex structure to a resin on a transfer substrate, in which a first step structure is formed on a main surface of a base, a second step structure is formed on the first step structure, and an outside region of the second step structure on an upper surface of the first step structure is covered with a light shielding film to solve the above problem.

An apparatus includes a first roll and a second roll on each of which a pattern is formed, a first motor and a second motor to rotate the respective rolls, a shaft direction supporting mechanism to support the second roll along a shaft direction and an axial position adjusting mechanism configured to move the shaft direction supporting mechanism along the shaft direction. The posture of the rotating shaft of the second motor is maintained constant at all times, and the second roll is moved in the shaft direction along the first roll, thereby adjusting the positions of both patterns on the first roll and the second roll along the shaft direction.

A three-dimensional printing system includes a resin vessel containing resin, an imaging bar, a movement mechanism coupled to the imaging bar, and a controller. The imaging bar includes an arrangement of light emitting devices that selectively emit radiation from an exit surface of the imaging bar to define a build plane in the resin. The exit surface of the imaging bar is preferably less than 10 millimeters from the build plane. The controller is configured to scan the imaging bar along a scan axis and, concurrent with scanning, operate the imaging bar to selectively image a layer of resin at the build plane.

A roller embossing method for flexible graphite polar plates of fuel cells comprises: (1) adjusting a clearance of an embossing roller pair of a roller press to a target thickness value of a monopolar plate; (2) feeding a flexible graphite slab in front of the embossing roller pair, and entangling the flexible graphite slab by means of opposite rotation of the embossing roller pair; (3) after the slab is entangled, continuing to forward roll the slab for 10-100 mm, and then reversely rolling the slab for 5-90 mm by means of synchronous and opposite rotation of an upper and a lower embossing roller, wherein one time of forward rolling and one time of reverse rolling are referred to as reciprocal rolling; (4) forming a polar plate after several times of reciprocal rolling, and separating the polar plate from the embossing rollers; (5) performing subsequent treatment on the roll-formed flexible graphite polar plate.
