Objet 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
For up-to-date information about PolyJet printing materials and their
properties, go to http://www.stratasys.com/materials/polyjet.
Materials used for printing models with Objet 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 16–27 degrees Celsius (60–81 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 cartridge.
•
Make sure that material cartridges are stored in accordance with all
local regulations and other applicable requirements.
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.
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.
