Figure 8-1: Objet 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.
Removing Support Material with Caustic Soda
Soak models in a 2 ‐ 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.
Storing Models
Models are cured as they are printed, making them safe and stable for a
long time. However, proper storage conditions and protection from ultra ‐
violet radiation are necessary to prevent deforming.
•
Keep printed models at room temperature and in a low ‐ humidity
environment.
•
Do not expose models to sunlight and other possible sources of ultra ‐
violet radiation.
Use caution when cleaning delicate models with high-pressure water
systems.
WARNING: Caustic soda may cause chemical burns, scarring and
blindness. Mixing it with water generates heat that could ignite other
materials.Take adequate safety precautions; always use nitrile gloves
when handling caustic soda and models soaked in it.
