Stratasys J850/J835 User Guide
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.
Removing SUP705/705B 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.
Removing SUP706/706B with Caustic Soda and Sodium Metasilicate
Soak 3D prints in a 2-percent solution of caustic soda (sodium hydroxide) and
sodium metasilicate (Na
you soak the 3D prints in the solution depends on how delicate it is and how
much support material needs to be removed. Rinse the 3D print thoroughly
under running water afterwards.
SUP706/706B will dissolve into the caustic soda and sodium metasilicate
solution and saturate it, reducing its effectiveness. Replace the solution
when the support material reaches 15% of the solution (after approximately
one month of average use).
