Abstract

The presently disclosed embodiments generally relate to reservoir manifold systems suitable for use with an additive manufacturing apparatus. Such manifold systems enable ease of use for making mechanical, electrical, and fluid connections to a reservoir used for additive manufacturing. Conduits formed in the reservoir manifold can allow for a fluid connection to be established with a reservoir to allow fluid flow into and out of the reservoir. The reservoir manifold can include one or more arms that are configured to move independently to couple to the reservoir of the printing apparatus. The reservoir manifold can include a trigger coupled to a latch mechanism for engaging one or more components of the apparatus. In some embodiments, the ability of the manifold to make electrical connections to the reservoir may present advantages to the ease-of-use and reliability of an additive manufacturing apparatus.

Claims (18)

1 . A method of additive manufacturing, comprising:

cycling fluid into and out of a reservoir while printing a plurality of layers using a portion of the fluid to form a three-dimensional object, the fluid that cycles out of the reservoir passing through at least one mixer prior to being cycled back into the reservoir, and

moving a reservoir manifold into an engaged position with respect to the reservoir such that an inlet conduit and an outlet conduit of the reservoir manifold forms a fluid connection with the reservoir to allow for the fluid to be cycled therethrough.

2 . The method of claim 1 , wherein moving the reservoir manifold further comprises rotating the reservoir manifold about a pivot point.

3 . The method of claim 1 , further comprising:

filtering the fluid proximate to a location at which the fluid enters into the reservoir.

4 . The method of claim 1 , further comprising:

filtering the fluid proximate to a location at which the fluid exits the reservoir.

5 . The method of claim 1 , further comprising:

heating the fluid in conjunction with cycling the fluid, the heating occurring outside of the reservoir.

6 . The method of claim 1 , further comprising:

monitoring a temperature of a fluid used for additive manufacturing; and

heating the fluid used for additive manufacturing while it is being circulated through a closed loop fluid path that includes the reservoir in which at least a portion of the fluid can be disposed prior to being used to produce the three-dimensional object and a heating element configured to heat the fluid.

7 . The method of claim 6 , wherein the closed loop fluid path further comprises a reservoir manifold having a plurality of conduits formed therein, the plurality of conduits forming a portion of the closed loop fluid path.

8 . The method of claim 7 , further comprising:

moving the reservoir manifold into an engaged position with respect to the reservoir to allow the plurality of conduits to connect with and form the closed loop fluid path.

9 . The method of claim 6 , further comprising:

operating a controller to heat the fluid in response to the monitored temperature.
