Support Material outside of the model. For delicate models, use a toothpick, pin or small brush
by Hand after dipping the model in water.
• For SUP705, after breaking away excess Support material, soak the model
• For SUP706, after breaking away excess Support material, soak the model
Removing For most models, the most efficient way to remove Support material is by
Support Material using a high-pressure water jet. One suitable system is the Balco WaterJet
with Water cleaning unit. This device is marketed by Stratasys.

Figure 5-1 Balco WaterJet Cleaning Unit
To clean a model using this device, you place it in the chamber, and you
manipulate it and the jet using the built-in, waterproof sleeves. A pump turns
ordinary tap water into a high-pressure jet, and a wiper keeps the window
clear.
Use caution when cleaning delicate models with high-pressure water
systems.
