Removing Support By Hand; Removing Support With Water Pressure - Stratasys J850 User Manual

Stratasys J850/J835 User Guide
SUP705 (FullCure705) and SUP706 support material can be removed from 3D
prints using the following methods, in this order:
1. by hand
2. water pressure (in a suitable cleaning unit)
3. SUP705: 1% caustic soda solution (recommended for a smooth finish)

Removing Support by Hand

While wearing protective gloves, break away excess support material on the
outside of the 3D print. For delicate 3D prints, use a toothpick, pin or small
brush after dipping the 3D prints in water.
• For SUP705, after breaking away excess support material, soak the 3D
• For SUP706, after breaking away excess support material, soak the 3D

Removing Support with Water Pressure

For most 3D prints, the most efficient way to remove support material is by
using a high-pressure water jet. One suitable system is the Balco WaterJet
cleaning unit. This device is marketed by Stratasys.
Figure 5-1
To clean a 3D print using this device, you manipulate it and the water using the
built-in, waterproof sleeves. A pump turns ordinary tap water into a high-
pressure jet. A wiper keeps the window clear.
Use caution when cleaning delicate 3D prints with high-pressure water
systems.
