You are responsible for ensuring that the facility where your Modular system and its resins are housed is properly configured for safe operation of the system and its resins. Personnel who operate the equipment or use the materials must comply with all relevant safety codes and applicable regulatory requirements and laws, particularly those that relate to usage of hazardous chemicals, optical radiation, and disposal of regulated material. The Figure 4 Modular complies with CE requirements.
NOTE: You are responsible for determining whether additional supplies and equipment are necessary according to local, state, federal or other regulatory laws that govern your location.
Figure 4 Material Usage
Figure 4 resins in the liquid state require use of approved surgical-type 100% nitrile gloves and other equipment to protect the user from direct contact with uncured resin. Resin is fully cured only after adequate exposure in a UV-curing unit. Only after being fully cured do the parts no longer require protective gloves to handle.
Because these resins are regulated, they are subject to special disposal requirements by your local, federal, or other regulatory agencies. Follow applicable disposal guidelines. Contact a local waste management company for recommendations on disposal requirements that affect your facility.
If your area requires regulated waste disposal, consult with and retain a waste-management company to periodically pick up regulated waste. Your local waste management company may recommend that you set up a drum, or other approved container, to dispose of uncured resin and of any materials that may have come into contact with the uncured resin. Examples of resin-related trash include, but are not limited to, the following items that might have resin on them: nitrile gloves, paper towels, broken cleaning containers, broken part-cleaning tools, partially cured printed parts, and used resin bottles.
Storage and Usage Guidelines
Always wear appropriate safety equipment, such as 100% nitrile gloves, when handling uncured resin. Protect your body from any direct contact with uncured Figure 4 resin.
- Always read the Safety Data Sheet (SDS) prior to use of any Figure 4 resin.
- Always use the oldest resin bottle first. All resins have a shelf life. Using the oldest resin first helps you to use all your purchased materials within that period of time. The expiration date of a resin will be printed on its bottle.
- During storage, shield the resin from sunlight or other sources of actinic radiation, such as fluorescent or mercury vapor lights. Exposing the resin to UV radiation increases product viscosity and chance for polymerization, making the resin unsuitable for part building. Storing resin above the maximum recommended temperature can also make the resin unsuitable for part building. Resins should be stored in the opaque, UV-resistant bottles they came in. If you must store resin in the resin tray outside the machine, store the tray in its garage with the UV-protective lid. Inside the Printer, the resin in the resin tray is largely protected by the orange acrylic door. Also, your 3D Systems installer will not install the machine close to sources of UV radiation.
- Store bottles of Figure 4 resins indoors at temperatures between 5°C-30°C (41°F-86°F). Storing at temperatures below this minimum or above this maximum could render the resin unusable for part building.
