How to quiet down the Objet waterjet pressure unit

This is just a quick tip on how to reduce the noise coming from the pressure unit for the smaller Objet Waterjet.  The water pressure used to clean the support material from the printed parts is generated by a pressure washer type unit.  This device is quite loud so I decided to try to find a way to make it quieter.

In our 3D printing lab, we have a sink and there happened to be enough space in the cabinet below it to fit the pressure unit.  I drilled a couple of holes in the side wall to allow the water lines to pass through and placed the pressure unit inside the cabinet.  This has dramatically reduced the noise in the room and also helped with the noise from it that is heard in the rest of the building.  A simple and inexpensive idea.  I’ll be trying to further reduce the noise in the future but this is a great start.

A perfect fit!
