Removing the Support Material
Afterprintedmodelshavecooled,thesupportmaterialmustberemoved.
Thiscanbedonebydifferentmethods,dependingonthesizeofthemodel,
howdelicateitis,theamountandlocationofthesupportmaterial,and
otherfactors.Usethefollowingmethodsasaguide,andadaptthem(or
a
combinationofthem)forfinishingthe modelsyouarehandling.

Caustic Soda
Soakmodelsina1‐percentsolutionofcausticsoda(sodiumhydroxide)to

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.
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.
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.
