Material Handling And Safety - 3D Systems FIGURE 4 MODULAR User Manual

2.2 Material Handling and Safety

Note: For complete safety information and instructions for use, please read the SDS and User Guide for the
Figure 4 material you are using. These documents are packaged in with each material cartridge.
HARMFUL IRRITANT WARNING: Always wear chemical-resistant gloves, goggles and protective clothing when
handling material. Avoid skin contact. Avoid breathing material fumes.
• Always practice standard lab hygiene and follow Personal Protective Equipment (PPE) requirements outlined in this manual.
• Always wear chemical-resistant gloves, such as nitrile, when working near materials or with partially cured
parts. It is recommended to wear approved goggles and protective clothing. Protective clothing includes, but is not limited
to: closed-toed shoes, full-length pants, and splash-resistant lab coats or equivalents. 3D Systems recommends using
100% nitrile gloves; however, other chemical-resistant gloves will suffice. Do NOT use latex gloves, as they do not provide
complete chemical protection.
• Wearing contact lenses when working with material is not recommended.
• Avoid breathing in vapors from material. To avoid breathing in vapors: when opening an upper or lower build chamber,
allow a few seconds to pass before putting your face near the opening. Your facility may require that Printer vapors be
vented to outside air. If this is the case, please see the section
information on external ventilation recommendations.
• Always wash skin thoroughly with a nonabrasive soap and COLD water after working with materials. DO NOT USE HOT
WATER OR SOLVENTS to wash hands, as these will stimulate your pores and result in absorption through the skin. Material is
sensitizing and can cause bad allergic reactions if absorbed through the skin. A person who becomes sensitized to material
should not work around that material in the future.
• If a small amount of material gets on your clothing, remove the article of clothing as soon as possible (it might be a good
idea to have a change of clothes on hand just in case). Have contaminated clothing dry cleaned. DO NOT wash in a regular
washing machine that drains into waste water. If a particularly large amount of material gets on your clothes, it is best to
discard them according to all local, state, and federal regulations. Keep contaminated clothing away from food and drinks.
Wash hands thoroughly after handling contaminated clothes, even if you wore protective clothing/gloves to handle them.
• Use extreme care when handling solvents used to remove excess material from uncured parts. Solvents like Isopropyl
Alcohol (IPA) and Ethanol (EtOH) are very flammable.
• Keep all materials away from heat, sparks, static discharge, and flame. Material containers may rupture when exposed to
extreme heat. We recommend storing your Figure 4 materials in a fire-resistant storage cabinet. Please refer to the SDS for a
particular material to view its flash point.
• High temperatures may cause a spontaneous polymerizing reaction, generating heat and pressure. Closed material
containers may rupture or explode during a runaway polymerization. Use a water spray or fog to reduce or direct vapors.
• Fire fighters should use a self-contained breathing apparatus and full protective clothing in the event of a material fire.
• Do not leave uncured, or liquid, materials in an area where persons who are not knowledgeable about their handling or use
may have access to them.
• Keep material away from food and drinks.
WARNING: USE FIRE EXTINGUISHERS SUCH AS CARBON DIOXIDE, DRY CHEMICAL, OR FOAM. A SPRAY OF WATER
MIGHT ALSO BE EFFECTIVE. DO NOT USE A DIRECT JET OF WATER OR SMOTHERING TO EXTINGUISH BURNING
RESIN OR SOLVENTS.
Material Characteristics
The photopolymers used in the materials may be hazardous if handled improperly. Repeated skin contact with materials
may cause sensitization. Consult the manufacturer's Safety Data Sheet (SDS) for information on specific materials. For further
information on this and related topics, consult the
WARNING: DO NOT MIX DIFFERENT RESINS TOGETHER.
Figure 4 Material Storage
Materials should be stored in the opaque, non-reactive containers in which they were provided, according to the guidelines
given in the SDS included with the material, and according to all applicable government regulations. Use the included
cartridge stands to store your cartridges upright. Protect material from sunlight, ambient light, and moisture. Be sure your
material-storage area is dry, dark, and between 5°C-30°C (41°F-86°F). It is preferable to store the material in a fireproof cabinet.
Improperly stored materials may increase in viscosity, and may eventually result in a gelled, polymerized product in the storage
container. Materials should be stored in conformance with applicable laws and regulations. The expiration date of the material
