Removing Support

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

Storing Models
Models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printedmodelsatroomtemperatureandinalow‐humidity
environment.
• Donotexposemodelstodirectsunlightandotherheatsources.
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. Never pour water into a caustic soda solution. 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.
