Line 28: − + − CatalystEX is the + − === Acid Bath ===+ − − ==== Procedure for Use ====+ − To use the Acid Bath, begin by grabbing a white mesh bag from the small drawer located directly under the Acid Bath. Place your part into the bag, and tighten the string on the top. At this point, you should now put on the goggles, located to the left of the bath, and the large rubber gloves, located to the right of the bath. Open the lid of the bath, and place the bag, with the part you want to dissolve inside of the bag, into the acid bath. Tie the excess string to one of the handles on the top of the bath, and close the lid. Rinse the gloves in the sink, and remove them once they are clean. Press the white button indicated on the image to begin the dissolving process. First, the Bath will heat the Sodium Hydroxide to 70 degrees Celsius, and then the dissolving process will fully begin. Depending on the size of the part, the bath could take several hours to dissolve the support material. − ==== Maintenance ====+ − Very little maintenance is needed for the Acid Bath, which comes in the form of replacing the Sodium Hydroxide and water mixture. In the event that the mixture is murky and not dissolving the part well, the Acid Bath will need to be emptied, cleaned, and refilled. Only those trained in this process will be allowed to do so, and If you notice that the Sodium Hydroxide needs to be replaced. bring it to the attention of either Justin, Ben, or Gabi. − ===== Emptying the Bath =====+ − Full instructions to come at a later date − + − Full instructions to come at a later date+ − − ===== Refilling the Bath ===== − Full instructions to come at a later date − − Each bottle of sodium hydroxide should contain approximately 250 g. After the tank is cleaned, add water FIRST to the tank and then pour the sodium hydroxide ON TOP of the water. '''''DANGER: Reversing this process causes a DANGEROUS chemical reaction.'''''

=== GrabCAD Print ===
GrabCAD Print is the software that both the Dimension and F370 use, and allows you to easily orient and view the part you want to model. Both printers are web based, which allows you to start the print from the one of the lab's computers.
On Opening GrabCAD, make sure that you select the printer you want to use for the part you want to print, the volunteers in the lab can help you determine which printer would work best. The menu the the right of the image shows the printer options, make sure you select the correct printer, in this case it is the Dimension. After ensuring you have the software correctly set up, open your file and place it on the build plate, '''''Note: your file has to be in STL format to work with any printing software.''''' The build plate is correctly scaled to the actual build plate, so when sizing up or down you can check the size and placement of the print with the build plate.
The Acid Bath is a heated tank of a Sodium Hydroxide and Water mixture, used to remove support material from parts printed on the Dimension and F370 Printers. The Acid Bath is to only be used by those trained in the Prototype Lab.

After opening and correctly orienting your part, you may see a red error like the one in the image above, to fix this, click analysis mode, the second icon from the top. The image below shows analysis mode,
