Recycling and disposal
9.1
Disposal of resin and accessories
Skin irritant: Resin and solvent may cause skin irritation or an allergic skin reaction.
Wear gloves when handling liquid resin, resin-coated surfaces, or solvent. Wash skin
with plenty of soap and water.
9.1.1
Liquid resin
To dispose of pure resin (resin that has not been cured or dissolved in solvent), add this waste
to your chemical waste stream.
ENVIRONMENTAL HAZARD: Refer to the safety data sheet (SDS) and local
authorities for guidance on disposing of resin and solvent. Liquid resin (whether pure
liquid, dissolved in solvent, or partially cured) may be classified as hazardous waste in
your region and shall be disposed of with care.
If you do not have a chemical waste stream:
1. Put on a new, clean pair of nitrile gloves.
2. Pour a small amount of resin into a labeled container suitable for storing resin.
3. Leave the container outside, exposed to sunlight to cure for 1–10 days. Expose resin to
405 nm light and heat for the most effective curing. The liquid resin cures to solid material
when exposed to light and heat.
4. Dispose of the fully cured resin and container in the household waste.
9.1.2
Cured resin or cleaned prints
Dispose of cleaned prints and cured (hardened) resin in the household waste. Cleaned prints
and cured resin cannot be recycled.
9.1.3
Empty resin cartridges
In the United States, empty resin cartridges are considered RCRA empty by EPA standards
and can be disposed of as household waste. Regulations that control waste are often regional
and vary by jurisdiction. Check with applicable local agencies to ensure that you are disposing
of empty resin cartridges properly.
OPTIONAL:
Triple rinse resin cartridges with clean solvent to remove traces of excess resin
from the resin cartridge interior. Add the resulting used solvent to your chemical waste stream
in accordance with all applicable regulations.
9.1.4
Resin tanks
Dispose of a resin tank when it is damaged, has reached the end of its lifetime, or is otherwise
unsuitable for use.
To dispose of a resin tank:
1. Put on a new, clean pair of nitrile gloves.
2. Remove the build platform from the printer.
3. Hold the side walls of the resin tank.
4. Gently slide the resin tank away from and out of the printer.
