==Description==
==Description==
The Dissolvable Support Bath is a SCA 1200 HT 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.

* Wear a lab coat, nitrile gloves, and safety goggles. This is very important. The granule Sodium Hydroxide (undiluted--undissolved) is much more dangerous.

*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.
