A system and method for providing centrifuge-based additive object manufacturing includes a rotating drum containing a photopolymer material that solidifies when irradiated by a light source, the photopolymer material spreads evenly over an item being manufactured when the rotating drum is in motion, a light source module emitting a light capable of solidifying the photopolymer material, a set of platform actuator elements coupled to a plurality of perforated platforms for controlling a position of the plurality of perforated platforms within the rotating drum while in operation, and a photopolymer material delivery system for adding a controlled amount of the photopolymer material into the rotating drum. The light source module moves inside the rotating drum and selectively emits its light solidifying the part of the layer above the plurality of perforated platforms in the areas crossing the object currently being manufactured.

The invention relates to a component having at least to some extent a layer structure, wherein the layer structure includes an elastomer layer with a density greater than 800 g/L, and a thermoset layer including at least 50% by weight of a first polyurethane. The invention further relates to a process for the production of a component of this type, the process including (i) provision of a female mold into which the individual layers of the layer structure are introduced, or of a male mold to which the individual layers of the layer structure are applied; (ii) production of the elastomer layer via spraying; (iii) production of the thermoset layer via spraying; and (iv) demolding of the resultant component. Step (ii) can be carried out before step (iii) or step (iii) can be carried out before step (ii).

A method of fabricating an artifact (15) includes treating natural fibers (110) with a non-halogenated flame retardant agent (120), the fibers (110) also being treated with a smoke suppressant (120). At least one pre-preg is formed (170, 180) from the treated natural fibers and from a resin composition (160) including a smoke suppressant (150) admixed therein (160). An uncured artifact is formed from a core or substrate (12) and the pre-preg, which provides a skin, and is cured (210). A non-fibrous silicate fire resistant material (190, 230) is introduced by: (i) admixing the fire resistant material with the resin composition, and/or (ii) applying the fire resistant material to an outer surface of the pre-preg or an outer surface of the skin of the uncured artifact, and/or (iii) applying the fire resistant material to an outer surface of the skin of the cured artifact. The invention extends to a flame-proofed artifact (15).

The instant invention is related to a method for replicating an object. The method includes providing an object comprising an outer surface and a channel; applying dry tannin powder to the outer surface of the object wherein at least a portion of the dry tannin powder adheres to the outer surface as imaging tannin; and placing an aqueous solution of an iron salt in the channel wherein the iron salt diffuses through the object to convert said imaging tannin into a replica of the object.
