The Dissolvable Support Bath is a 1200 HT Support Cleaning Apparatus. 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.

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. The bath is only to be used for ABS models with QSR dissolvable support. PLA placed into the bath will become brittle and break apart, ruining the prints.

#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.
 +
#*Mesh bags are located in the small drawer next to the sink.
 +
 
 +
''When removing parts:''
 +
 
 +
#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.

−
***This is not an exact science. Before the F370, all dissolvable support material was a translucent black. This meant that the bath would become a milky brown when it needed to be changed. Now the F370 introduces an opaque white material which causes the bath solution to continuously appear milky which creates confusion when trying to figure out when to change the solution.
 
−
***As of right now, we recommend making a best guess. When the bath starts taking a very long time to dissolve support material, it is probably time to change the bath.
 
−
***Some thoughts for changing this in the future:
 
−
****Use the Job Log's ability to track the support material dissolved in the bath and develop a number for when the bath needs to be changed. Then set the Job Log up to alert the Lab when it has reached that number.
 
−
****Attempt to obtain translucent black support material for the F370.
 
−
****Attempt to use a chemical strength measurement to determine how strong the solution in the bath is and determine a checkpoint strength for when to switch the solution.

Dissolvable support bath (1).png
This is a Dissolving Support Bath.

Make: Support Cleaning Apparatus

Model: 1200HT

Serial Number: 8121546

Ace: Ellie Annah (estrauss21@georgefox.edu).

Location: Prototype Lab


Description

The Dissolvable Support Bath is a 1200 HT Support Cleaning Apparatus. It is used in conjunction with both Stratasys 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. The bath is only to be used for ABS models with QSR dissolvable support. PLA placed into the bath will become brittle and break apart, ruining the prints.

Demonstration

Use the correct safety procedures to place a printed part in the bath.

General Procedure

  1. ALWAYS USE SAFETY ATTIRE (see safety for requirements).
  1. Flip the rocker switch on the bottom right to turn the bath on.
  2. Select the temperature that correlates to your print material (70 degrees for ABS) and press the power button to begin the heating process.
  3. Keep the lid shut as much as possible.
  4. 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.
    • Mesh bags are located in the small drawer next to the sink.

When removing parts:

  1. 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.
  2. 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.
  3. Replace the basket and lid.

Maintenance

General maintenance

Like many machines in the Maker Hub, the bath must be periodically wiped down to keep it clean and working properly. This also removes spots created by the Sodium Hydroxide. Also, there is a limit to how much support material can be dissolved and once it has been reached the tank must be emptied and refilled with new Sodium Hydroxide solution.

Specific Maintenance Tasks

Maintenance Procedure Frequency Done By Last Done
1 Wipe down the machine As neeeded Lab Volunteer N/A
2 Change the Bath Solution When the bath starts taking a very long time to dissolve support material Lab Volunteer 1/23/20
3 Refill Sodium Hydroxide Bottles If there is only one full bottle remaining Lab Volunteer

2. How to change the solution in the bath:

  • Wear safety attire during the entire process.
  • Retrieve a barrel to drain the fluid into.
  • Remove the blue silicone cap.
  • Align the barrel opening to be underneath the drain spout.
  • Open the ball valve so the fluid begins to drain.
  • Completely drain all of the fluid.
  • Clean the inside of the tank:
    • Use water to rinse out the inside of the tank then use paper towels to wipe out the gunk.
    • Be sure to also clean the basket thoroughly.
    • Replace the basket.
  • Fill the bath up with water (use the clear bucket under the sink, fill this with water from the sink, pour the water into the bath) until the water level reaches about 0.5" below the max fill line
  • Gather 6 packages of EcoWorks (1 package consists of part A and part B).
  • Inside each package the powder is in dissoluble bags, gently place all bags from the 6 packages into the water.
  • Turn the bath on and allow it to heat up to 70 degrees Celsius.

3. How to fill new Sodium Hydroxide bottles:

  • 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.
