Material Storage and Handling for PolyJet Printers and Material Safety Data Sheets

Material Storage

Model and Support material for Polyjet printers should be stored indoors in a dry area with adequate ventilation. They should be stored at a temperature between 59 to 77 degrees.

Never expose these materials to heat, sparks, flames or direct sunlight. When exposed to heat or flames the cartridges may burst or ignite.

Keep the materials away from areas where food or drinks will be stored, prepared or consumed. Be sure to wash your hands thoroughly after handling or coming into contact with uncured material.

Plastics made from monomer soluble substances such as polystyrene or polyvinyl chlorine are not suitable for storing these materials. They will eat through styrofoam and other similar materials.

Make sure the cartridges are stored in accordance with all local laws and regulations.

The materials have a limited shelf life. The expiration date is stamped on the cartridge.

The expiration date on the cartridge is valid when the material is properly stored in an unopened, undamaged cartridge.

Always use the oldest material in your stock first. When the material is expired the printer will not allow it to be used.

Handling Precautions and First Aid

Material that is not cured is considered hazardous industrial waste and requires certain precautions when directly handling it or disposing of it.

To prevent skin irritation you should wear neoprene or nitrile gloves.

Prolonged skin exposure to uncured material can cause an allergic reaction.

You should wear goggles anytime there is a chance that the material may splash into your eyes.

When handling parts where the material has not fully cured you should also wear gloves.

To prevent respiratory irritation you should make sure that the area the printer is operated in has adequate ventilation.

The ventilation system should totally replace the air at least 4 times in an hour.

Clean up spilled material with disposable towels or other absorbent non reusable material such as saw dust or activated charcoal.

Rinse the spill area with denatured or isopropyl alcohol and then clean with soap and water.

Dispose of the towels or absorbent material according to local regulations.

Try to avoid direct contact with uncured material

If skin or eyes come into contact with material follow these guidelines:

Wash the area immediately with water.

For contact with skin, wash with cool soapy water. Hot or warm water will open the pores in your skin.

Do not use solvents to clean skin.

For prolonged irritation or if blisters appear seek medical attention immediately.

Avoid accidental contamination from hands to other parts of the body, especially the eyes.

If material comes in contact with the eyes flush with large amounts of water for 15 minutes and seek medical attention immediately. Avoid sunlight, fluorescent light and any other forms of ultraviolet radiation.

Wearing contact lenses is not recommended when handling material.

If contact lens comes into contact with material remove the lens and flush the eyes with large amounts of water and seek medical attention immediately..

If material is swallowed follow the instructions on the material bottle and seek medical attention immediately.

Vapors from printing materials can be irritating to the respiratory system. If irritation occurs seek fresh air immediately.

If victim stops breathing perform CPR and seek medical attention immediately.

Waste Disposal

Fully cured material can be disposed of as ordinary waste but uncured material is considered hazardous industrial waste.

This material must be packaged and disposed of in accordance with local regulations.

Empty material cartridges still contain some residue inside and should also be disposed of according to local regulations.

The waste material can be fully cured by exposing it to UV light. Some people will set the waste material out in the sun or under a UV lamp and let it fully cure before disposing of it.

Once the material is fully cured it can be disposed of as ordinary trash.

You must contact a waste disposal company in your area to pick up the uncured waste and dispose of it properly if you do not fully cure the material.
