Tip:
A fan or hair dryer can be used to harden the surface layers more rapidly. This allows for quicker han-
dling. Note the part may still be weak, so handle with care.
Dry the Part
Allowed to air dry at room temperature, the part will be dried to touch within a couple hours and fully dried
within 24 - 48 hours.
For faster drying, the parts can be placed in an oven set to 70° C for 1-2 hours. This also helps guarantee
maximum whiteness of the parts. Drying time may vary depending on your oven and the size of your mod-
els.
Note:
If you dry your models at room temperature, a splotchy pattern may appear on your parts after sev-
eral days. This can be prevented or removed from a part by drying it for 1-2 hours at 70° C.
4.1.6 Dipping method
Prepare the Salt Solution
1. Measure enough tap water into the container to submerge your part completely and allow room for
handling.
2. Allow room in the container for the volume of salt and for the water that will be displaced by your part.
3. For each 1
volume
of water, add 0.7
volume
of salt (see table below).
Note:
If the amount of salt mixed in is incorrect, the salt solution may be too dilute and parts may become
weak during spraying.
Tip:
Using warm water helps the salt dissolve faster.
4. Stir the water solution intermittently until the salt completely dissolves (5-10 minutes).
If there are any undissolved crystals at the bottom, allow 1-2 hours to dissolve, and then stir again for
1-2 minutes.
Note:
Failure to dissolve all the salt could cause crystals to deposit onto your part when you dip it.
Dip the part
Tip:
Wear gloves while dipping models to keep the bath clean and prevent mold growth.
1. Gently submerse the part in the bath for at least 5-10 seconds or until bubbles subside.
2. Slowly remove the part and hold it above the bath for 5-10 seconds to allow a majority of the excess
water to run off. Rotate the part to help the water escape from any cavities or crevices.
3. Move the part to the paper towels and gently dab the bottom of it on the dry paper towels.
Tip:
Avoid wiping the excess water on the top surfaces with a paper towel as this will compromise surface
finish.
4. Place the dipped part on the wax paper and allow it to air dry for 1-2 hours before handling.

dling. Note the parts may still be weak, so handle with care.
