REMOVING SUPPORTS - OPTIONAL ULTRASONIC SUPPORT REMOVAL TANK
The Ultrasonic Support Removal Tank automatically removes PLA support material from ABS models. There are two methods for
removing or weakening the material.
Method Advantages Disadvantages
Hot Water • Corrosive chemicals are not used. • Support material requires physical force to crumble
away.
• Support material in hidden cavities may remain if
the user is unable to reach them.
• The process can be more lengthy.
Caustic Soda • Support material is quickly removed.
• Support material hidden in cavities will be dissolved
without physical force.
• Requires health and safety procedures.
Hot Water Method
CAUTION: This process uses hot water (approximately 80°C or 176°F). Wear all Personal Protective Equipment
(PPE).
CAUTION: Do not operate without water in the cleaning tank. Damage may occur.
CAUTION: Never use boiling water. Damage may occur.
CAUTION: The unit must be positioned on a at, stable work surface. Do not tip over or move the tank during its
operation. Electrical equipment can become damaged when exposed to water or other uids.

2. Place the models to be cleaned into the tank.
3. Close the lid.
4. Connect the power supply and press the power button to turn on the tank.
5. Set the temperature to 80°C (176°F). Use the -5 and +5 buttons to lower or increase the temperature.
6. Set an alarm for 48 hours.
NOTE: Do not use the timer on the tank. This is intended for the ultrasonic operation used with the Caustic Soda
method and will only run for 180 minutes.
7. After 48 hours, remove the model from the tank using the included plastic tongs and immediately run cold water over it for 1 to 2
minutes.
