Venturi Vacuum Degassing Apparatus for use in Rapid Biomedical Part Prototyping

Step 2 Making the Vacuum Chamber: "Dollar Store Style"

The container that we'll use has to be sturdy enough so that it won't collapse when you pull a vacuum on it (I learned that the hard way) and it needs to be deep enough to hold the mold for the model that you are working with. The container in this image has strong corners, a strong rim and is deep enough to hold the small molds that we want to the pull bubbles out of (de-gas).

The short segment of hose has to be rigid enough so that it won't collapse under the vacuum. The quick connect for the other end is not necessary but you can get it at any hardware store. The threaded end is only threaded on one end, the other end of the connector has a bayonet tip that goes into the tube.
