Removing SUP710 Support with Caustic Soda

Soak 3D prints in a 1-percent solution of caustic soda (sodium hydroxide) to
remove support material from difficult-to-reach areas and to give the 3D print a
smooth, clean finish. The amount of time you soak the 3D prints in the solution
depends on how delicate it is and how much support material needs to be
removed, but it is typically between half-an-hour and several hours. In any
case, you should remove as much support material as possible before the
caustic soda treatment, and rinse the it thoroughly (with a water jet) afterwards.
Warning
Caustic soda may cause chemical burns, scarring and blindness. Mixing it
with water generates heat that could ignite other materials. Never pour
water into caustic soda. When diluting the solution, always add caustic soda
to water. Take adequate safety precautions; always use nitrile gloves when
handling caustic soda and 3D prints soaked in it.

Post-Printing Treatment

Post-printing treatment is recommended for 3D prints with several special-
purpose materials or for special applications. Recommendations for treating
and finishing 3D prints after printing are described in the Best Practices for the
desired printing material available on the

Photobleaching for Transparent 3D Prints

3D prints fabricated with clear materials, such as VeroUltra ClearS (RGD821)
have a slight yellow tint when removed from the printer. This is especially true
for 3D prints with a glossy finish. The yellow tint fades naturally over time, but
you can greatly accelerate this process by using a suitable photobleaching
treatment. This involves exposing 3D prints to intense light immediately after
printing.
Photobleaching methods and instructions are described in the Best
Practices for the relevant clear material. These are available on the
Transparent materials page on the Stratasys Support

Storing 3D Prints

3D prints are cured as they are printed, making them safe and stable for a long
time. However, proper storage conditions are necessary to prevent deforming.
• Keep 3D prints at room temperature and in a low-humidity environment.
• Do not expose 3D prints to direct sunlight and other heat sources.
