A mold assembly may include a mold frame having an opening extending in a plane and a movable mold insert adjuster to move a mold insert having a slot forming protrusion within the plane within opening.

According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.

Methods and apparatuses are disclosed to mold complex shapes using a cast mold technique. A catalyst-initiated urethane can be used for these complex shapes as there is little thickness restriction on any part dimension. Moreover, urethane, once chemically activated, can be poured into cast molds with various shapes. Due to the exothermic nature of urethane, when the curing chemical reaction takes place, metal molds can be fabricated from aluminum. Cast molds, made from aluminum, utilize elastomeric seals to account for coefficients of thermal expansion.

The present invention is directed toward an apparatus and method for consumer manufacture of suppositories for rectal or vaginal delivery allowing for the removal of formed suppositories while mitigating the deformation or damage to the formed suppositories when removed.

A build plate, a mold, a sheet of perforated metal foil, and a sheet of pre-preg fibers are disclosed for use in 3D printers. The build plate and mold are designed so that the build surface of the mold is automatically and implicitly registered in the coordinate system of the printer. The mold, the sheet of perforated metal foil, and the sheet of pre-preg fibers provide a mechanism for precisely controlling the amount of adhesion experienced by the nascent article of manufacture at each location of the build surface.

A method of fabricating a composite structure includes laying at least one composite ply about a bladder, the bladder comprising a phase change material in a first phase having a first volume, positioning an outer mold about the bladder and the at least one composite ply, and curing the at least one composite ply to form the composite structure. Curing causes the phase change material contained within the bladder to change to a second phase to expand from the first volume to a second volume and apply a pressure to an interior surface of the composite ply and press an outer surface of the composite ply against the outer mold to form an interior cavity. The bladder is not removable from the formed interior cavity.

In general, in various embodiments, the present disclosure is directed systems and methods for producing a porous surface from a solid piece of polymer. In particular, the present disclosure is directed to a mold for processing a material. The mold includes a body having a top surface and a bottom surface. A void within the body is configured to receive a porogen and a piece of thermoplastic material. The void extends in a top to bottom direction to form a non-through cavity with a cavity surface that is substantially parallel to the bottom surface of the body. A protrusion on the body extends from the cavity surface towards the top surface. The void extends at least halfway through the body towards the bottom surface. A peg is disposed on the body and shaped to matingly engage a weight via a hole within the weight.
