Abstract: An additive elastomeric manufactured part having an elongation at break of at least 50% may be made by a method comprising the following. A material comprising a prepolymer and filler is first dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.

Abstract: A porous inorganic additive manufactured article that is comprised of at least two layers of inorganic particulates bound together by a carbon binding phase throughout. The additive manufactured article may be formed by additive manufacturing using a mixture comprised of an organic reactive material and inorganic particulates, wherein the organic reactive material is subsequently reacted to form a thermoset material that forms carbon upon heating that binds the inorganic particulates together to form the porous inorganic additive manufactured article. The porous inorganic additive manufactured article may then be infiltrated with a liquid that is solidified to form a composite article or may be further heated in a differing atmosphere to form a further sintered or reacted porous inorganic article.
