  • Patent number: 10493500
    Abstract: A system for removing soluble support material from a prototype part may include a container for receiving the prototype part. A pump may be in fluid communication with the container and may be configured to pump a solution into the container and out of the container. A cooling module, such as a heat exchanger, may be in fluid communication with the pump. A temperature sensor may be operatively coupled to the cooling module and may activate the cooling module if a sensed temperature exceeds a threshold.

  • Patent number: 9581502
    Abstract: A temperature control apparatus includes a temperature monitoring integrated circuit (IC). The temperature monitoring IC has an output pin and is configured to generate an output signal having a voltage dependent on a sensed temperature. An output terminal is operatively connected to the output pin. An insulating material substantially surrounds the temperature monitoring IC. The insulating material substantially insulates the temperature monitoring IC from ambient heat and electromagnetic interference.

  • Patent number: 9533330
    Abstract: A container has been devised for use with a rapid prototype part making machine, specifically of the type having Fused Deposition Modeling (FDM) capabilities. The container includes a liner that has an exterior surface and that is expandable to define a mouth portion and a volume for receiving, via the mouth portion, a rapid prototype part having soluble support material deposited on the rapid prototype part. An inlet port is formed on the exterior surface and is in fluid communication with the volume. An outlet port is formed on the exterior surface and is in fluid communication with the volume. A sealing arrangement is configured and arranged to selectively substantially prevent egress of an aqueous cleaning solution from the mouth portion of the liner. The inlet port is configured to introduce the aqueous cleaning solution into the volume to remove the soluble support material from the rapid prototype part.
