A catalyst alarm system for resin/catalyst spray applications, the system having a first flow sensor that monitors whether a catalyst from a manifold is flowing for supply to a spay gun or other applicator at a specified minimum rate; a second flow sensor that detects if the catalyst is flowing out of a bypass conduit of the manifold, which indicates the catalyst is not being mixed with the resin; a third flow sensor that detects if the catalyst is flowing out of an over-pressure conduit of the manifold, which indicates that only a partial amount of the required catalyst is being mixed with the resin; and monitoring circuitry for providing alarm and/or control features based on activation combinations of the three flow sensors.

Catalyst flow sensor

An assembly for additive manufacturing includes a build housing including a base, a print head, and a print head support connected to the base for supporting the print head above the base. A driver system is provided for moving the print head and the base relative to one another. A build platform comprising a build support and at least one platen. The build support can be detachably engageable to the housing. The platens can be detachably engageable to the build support. The build support can include registration structure for registering the position of the build support relative to the build housing. A method of additive manufacturing is also disclosed.
