Removing Support With Water Pressure; Removing Sup705 With Caustic Soda - Stratasys J4100 User Manual

Stratasys J4100 User Guide

Removing Support with Water Pressure

For most models, the most efficient way to remove Support material is by using a
high-pressure water jet. Consult Stratasys Customer Support for advice on
purchasing and using suitable cleaning units for your printer and requirements.
Use caution when cleaning delicate models with high-pressure water
systems.

Removing SUP705 with Caustic Soda

Soak models in a 1-percent solution of caustic soda (sodium hydroxide) to
remove Support material from difficult-to-reach areas and to give the model a
smooth, clean finish. The amount of time you soak the model 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 model 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 models soaked in it.
Caution
Caustic soda causes corrosion of the build tray.
Remove models from the build tray before treating them with caustic soda. Do
not immerse the build tray in the caustic soda solution.
