Printing Materials
Objet260 printers produce models by jetting thin layers of printing materials
on the build tray, until the complete model is formed. Two types of material
are used in this process:
•
Model
material—which makes up the finished model
•
Support
material—which fills gaps and spaces in the model during
printing, and is removed after printing

Storage
Materials used for printing models with Objet260 printers are made of resins,
which are composed of reactive monomers and oligomers. Although printing
materials are supplied in sealed, UV-proof cartridges, care must be taken
when storing and handling them. Follow these guidelines to protect operators
and the environment, and to ensure optimum results.
• To ensure product stability, do not allow these materials to come into
contact with metal. Plastics made from monomer-soluble substances (such
as polystyrene or polyvinyl chloride) are not suitable for storing PolyJet
printing materials.
• When not in use, keep material cartridges tightly sealed to prevent
contamination, the effects of exposure to UV radiation, and accidental
spillage.
• Store material cartridges indoors, in a dry area with adequate ventilation,
between 15–25 degrees Celsius (59-77 degrees Fahrenheit). If exposed to
heat or flames, cartridges might burst or ignite.
• Signs of premature polymerization in material cartridges include bulging,
leaking, the emission of heat, and unusual odor. Exposure to heat can
cause resin to gel in the cartridges.
• Make sure that material cartridges are stored in accordance with all local
regulations and other applicable requirements.
Shelf Life
Materials used for producing models have a limited shelf life. The expiry date
on the label is valid when properly stored in an undamaged, unopened
cartridge. Always rotate your stock, so that the cartridge with the earliest date
is used first.
Exposure to
Light
If printing materials are not in their sealed cartridges, make sure to shield
them from sunlight and other sources of UV radiation, such as fluorescent
and mercury-vapor lights. Exposure to UV radiation causes an increase in
viscosity and, eventually, solidification.
