==Description==
==Description==
The Dissolvable Support Bath is a Thermo Haake DL30 Circulating Bath. It is used in conjunction with both Stratasys [[F370 3D Printer|F370]] 3D printers. Since these printers use QRS support material, the support can be dissolved in a heated, agitated, diluted solution of Sodium Hydroxide. Sodium Hydroxide can be dangerous when handled incorrectly, therefore there are various safety procedures associated with the use of the Dissolvable Support Bath. Below is a video of an alcohol dissolvable support bath which is not as toxic but functions the same.

====Operation====
Using the Dissolvable support bath is very simple. During the busy times of the semester, the bath will be left on but if it is not on then turn it on using the control panel. Next, wait for the bath to heat up completely and then place your part in it using appropriate safety attire. It may be helpful to place the part in a mesh bag, remove the basket from the bath, and tie the bag to the bottom of the basket to keep the part completely submerged. Periodically check the part until all support has been dissolved. Always wear safety equipment when opening the bath.

PLA placed into the bath will become brittle and break apart, ruining the prints.

====General Procedure====
====General Procedure====
#Flip the black switch (inside the yellow rectangle) to turn the bath on.
#ALWAYS USE SAFETY ATTIRE (see safety for requirements).
#Then press the button circled in red to start the heating process.
#Flip the rocker switch on the bottom right to turn the bath on.
#Keep the lid shut as often as possible.
#Select the temperature that correlates to your print material (70 degrees for ABS) and press the power button to begin the heating process.
#Keep the lid shut as much as possible.
#Place the part inside of a mesh bag, tie the strings of the mesh bag to the side handles, allow the part to soak in the bath for several hours.

#When the soaking step is completed, the basket can be lifted out and removed so that parts can be sifted through in the air instead of the solution. If you do remove basket, remove the lid first and place it in the sink. Next, lift the basket, let it drain above the bath so that it drips into the bath, then once it is barley dripping, the basket can be transferred to the sink.

#Wash the mesh bag and part thoroughly. Use paper towels to dry the part and let the part sit on paper towels and drain for a couple hours. Always inform the part's creator to wash their hands after handling the part and before eating or touching their eyes/face.

*There should be a mini funnel in the lab somewhere (it tends to move around some). Use the large Sodium Hydroxide bottle and mini funnel to refill the small bottles to the same level as the last remaining bottle. Always leave one bottle filled as a gauge for where to refill to. If a bottle has not been left filled, then fill the small bottle to about 1.5 inches below where the narrowing of the bottle begins.
