The invention relates to an integral irradiation unit for hardening light-hardening polymer compositions, a method for producing hardened polymer molded bodies or bodies coated with hardened polymers using the integral irradiation unit, and to the use of the integral irradiation unit for producing molded polymer bodies or bodies coated with polymers.

A flexible caul for applying pressure to a part comprises a caul member having a plurality of spaced apart gaps therein to provide the caul member with flexibility, and a flexible covering that limits flexing of the caul member.

A method for efficiently manufacturing and fabricating microfluidic chips, where a base mold is formed to have positive-relief features used to cast an intermediary template chip with negative-relief features having dimensions of a scale in the micron range. The intermediary template chip is used to case a production mold, which is formed of a reinforced epoxy resin that, once hardened into a solid epoxy member, can withstand the structural pressures of a CNC machining system. The production mold can be refined by a CNC machining, where the refined production mold is then used to cast production chips to be used as microfluidic chips.

A hollow-cylindrical device (1) having first and second openings (2, 3) for continuous production of a dental composite block. A curable composite material (4) and a temperature control unit (5) are provided. The composite material (4) is introduced into the device (1) through the first opening. The composite material (4) is cured by energy from the temperature control unit (5). An energy input occurs across a defined length of the substantially hollow-cylindrical device (1) and/or for a defined period of time. The composite material (4) is subsequently guided through the first opening (2) of the device (1). The composite material (4) is discharged from the second opening (3). In a first region along a portion of the length of the device, the device is either provided with an insulation or the flow-through device has a heat conductivity of 0.05 to 12 W/(m×K).

Provided is a method of forming a shaped structure. The method includes coupling a first section of a mold to a second section of the mold such that a mold cavity is defined, wherein a cross-sectional shape of the mold cavity corresponds to a cross-sectional shape of the shaped structure and wherein at least one of the first section of the mold and the second section of the mold comprise a soluble material; at least partially filling the mold cavity with a curable polymer; and curing the curable polymer in the mold cavity to make the shaped structure.

A riblet forming system incorporates a gantry which supports a laser and a paint applicator is positioned and moved over an aerodynamic surface. A computer control system is connected for control of the gantry on a predetermined path over the aerodynamic surface and further connected to the laser to control cutting a riblet topography along the predetermined path in a predeposited paint layer.
