Manufacture of a 3D object by a printing method that enables the use of several reactive materials sequentially. A laser-enhanced jetting-based 3D printer forms successive layers of reactive compositions on one another and the first and subsequent layers are allowed to crosslink between the printings to ultimately form the 3D object. Additional reactive compositions may be printed prior to the crosslinking. The crosslinking may be effected by heating, with or without a catalyst, and post printing curing may be employed after the 3D object is formed.

The present invention relates to a male component or punch for a mould unit for producing a vehicle saddle.

Provided is a sheet molding compound having excellent thick portion-molding properties that can inhibit the occurrence of internal cracks even during the molding of a thick portion and enables a carbon fiber composite material molded article to be excellently released from a die. Also provided is a carbon fiber composite material molded article. The sheet molding compound of the present invention contains a fiber substrate (A) containing carbon fiber and a thermosetting resin composition (B), in which an average fiber length of the carbon fiber is 5 mm or more, and a volumetric molding shrinkage rate of the thermosetting resin composition (B) is 0.5% or more and 4.4% or less. Furthermore, the carbon fiber composite material molded article of the present invention has a thick portion having a thickness of 10 mm or more, in which the thick portion is formed of a cured material of the sheet molding compound of the present invention.

This application relates to an anti-stiction flexible mold comprising a layer of an anti-stiction silicon dioxide deposited onto a flexible substrate. There is also provided a method for fabricating an anti-stiction flexible mold comprising the steps of a) depositing a layer of silicon dioxide on a flexible substrate; and b) interacting the layer of silicon dioxide with an anti-stiction agent to form the anti-stiction flexible mold. The resulting anti-stiction flexible mold may have superior anti-stick properties and may enable easy separation of mold and substrates after imprinting.

A mold for casting a micro-scale structure includes an upper surface including a first cavity having a first depth. A negative pattern for an array of micro-scale structures is defined in a surface of the first cavity. The mold includes at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures. The at least one second cavity defines a negative pattern for a standoff of the micro-scale structure. A fabric retaining frame is disposed in the first cavity.

Embodiments herein relate to substrates for use in a selective toner electrophotographic process (STEP) additive manufacturing system. The substrates include a build platform for use in STEP additive manufacturing system, the build platform comprising a build substrate for receiving a build material deposited by a STEP process; wherein the platform has selected thermal properties, such as within 30 percent of the build material to be deposited onto the substrate.

A method of manufacture of a composite aircraft article aerodynamic surface by forming the composite aircraft article aerodynamic surface on an aircraft article composite forming tool. The aircraft article composite forming tool includes a matrix laminate including an upper ply including a forming surface for forming the composite aircraft article aerodynamic surface. The upper ply of the aircraft article composite forming tool includes a nano filament structure embedded therein. A blank is conformed onto the aircraft article composite forming tool. The aircraft article is formed on the upper ply of the forming surface. The forming surface of the aircraft article composite forming tool is adapted to form an aerodynamic surface of the aircraft article. The blank is cured into the aircraft article. The composite aircraft article is finished.

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.

An object has a durable superhydrophic, self-cleaning, and icephobic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of hierarchical structuring micro/nanoparticles, liquid silane having one or more groups configured to graft to a hierarchical structuring micro/nanoparticle and at least another group that results in hydrophobicity. The hierarchical structuring micro/nanoparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting binders, moisture curing adhesives or polymers that form a strong interaction with a surface, is in solution with a solvent. Upon curing, the layer has a contact angle greater than 90 and a sliding angle of less than 10 and, less than 5% of an area of the layer is removed in a Tape test.
