Removing Models After Printing
After printing models, you should allow them to cool as much as possible
before handling them. If additional models do not have to be produced on the
printer, it is best to let the printed models cool in the printer, with the cover
closed, as long as possible.
If the printer must be used to produce additional models as soon as possible:
1. Let the printed models cool on the build tray for at least 10 minutes.
2. Very carefully, remove the models from the tray with a scraper or spatula
Warning:
Wear protective gloves when handling printed models before they are
washed.
3. Place the models on a flat surface, and cover them with a cardboard box
4. Let the models cool for several hours.
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 type of Support
material, 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.
There are two types of Support material available:
• SUP705 (FullCure705), a gel-like Support material.
• SUP706, an easily removed Support material that dissolves in a solution of
SUP705 (FullCure705) and SUP706 can be removed from printed models
using the following methods, in this order:
1. by hand
2. water pressure (in a suitable cleaning unit)
3. SUP705: 1% caustic soda solution (recommended for a smooth finish)
