Abstract

An open mold for producing components made of a moldable material such as layered composite materials is made from an additive manufacturing technology. The mold includes at least two compatible mold segments which precisely interlock with and abut against each other. The mold thereby made may be larger than the limited printing area of an additive manufacturing machine.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to Canadian Patent Application No. 3065462 filed Dec. 18, 2019, the disclosure of which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTIONField of the Invention

[0002] The present invention generally relates to the field of molds for the production of molded parts which can be made of composite materials for example. More specifically, the invention relates to a mold made using an additive manufacturing technology and to a method of producing such a mold.Description of Related Art

[0003] Molds used in the production of components made from composite materials using a reinforcing fabric in a matrix are typically themselves made out of composite materials. Current mold technology first requires the production of a plug, which is an intermediate component representing the surface of the composite material component that is to be ultimately molded in the mold. The plug is then polished ...
