MATERIAL STORAGE AND SAFETY
NOTE: The ProX 800 User Guide contains the full scope of safety information that applies to your SLA system .
Read through the User Guide before operating any equipment or handling any material .
You are responsible for ensuring that the facility where your SLA system and printing materials are housed is properly
configured for safe operation of the SLA system and of the materials used in that system. 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, laser radiation, and to disposal of regulated material . The
system conforms to Federal Laser Product Performance Standards 21CFR1040 .10 Class I laser in normal operation and/or
bypass mode. During field service, during which only trained service engineers have access to the SLA system, emission levels
correspond to a Class IV laser product . The ProX 800 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 .
STEREOLITHOGRAPHY MATERIAL USAGE
SLA materials in the liquid state require use of approved surgical-type 100% nitrile gloves and other equipment to protect
the user from direct contact with the uncured, or liquid, material . In general, liquid material is fully cured only after adequate
exposure in the ProCure UV chamber; only after being fully cured, do the parts no longer require protective gloves to handle .
MATERIAL STORAGE
Prior to actual use of the material, read the Material Safety Data Sheet / Safety Data Sheet (MSDS/SDS) for the material(s)
that you have selected; follow the instructions and guidelines that those documents provide . You may also refer to the resin
manufacturers' material safety and handling guides for more information about material handling .
MATERIAL DISPOSAL
Because stereolithography materials 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 .
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 . If your area requires a 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 liquid print material and of any materials (such as paper towels or gloves) that
may have come into contact with the uncured liquid print material .
After part building in the SLA system, the parts are not yet fully cured, and must be post-cured using the ProCure UV Chamber .
After an adequate period of UV light exposure in the ProCure chamber, the parts should be fully solidified and then may be
handled without the precaution of gloves .
NOTE: Inspect your parts after curing in the ProCure UV chamber to ensure they are fully solidified. Part surface
tackiness, visible or discernible areas of liquid resin indicate the part is not fully cured .
Storage and Usage Guidelines
•
Always wear appropriate safety equipment, such as 100% nitrile gloves when handling uncured liquid print material .
Protect your body from any direct contact with uncured print material .
•
Always read the MSDS/SDS prior to use of any print material .
•
Always use the oldest SLA material first. All materials have a shelf life, usually one year from the date of manufacture.
Using the oldest material first helps you to use all your purchased materials within that period of time.
•
During storage, shield the SLA material from sunlight or other sources of actinic radiation, such as fluorescent or
mercury vapor lights . Exposing the print material to UV radiation increases product viscosity and polymerization,
making the SLA material unsuitable for part building . Storing print material above the maximum recommended tem-
perature can make the it unsuitable for part building .
•
Keep the storage area away from ammonia .
•
Store containers of SLA materials indoors at temperatures between 16 °C (60 °F) and 27 °C (80 °F) . Storing at tem-
peratures above this maximum could render the material unusable for part building .
