Printing Materials

Stratasys J850/J835 printers produce 3D prints by jetting thin layers of printing
materials on the build tray, until the complete 3D print is formed. Two types of
material are used in this process:
• Model material—which makes up the finished 3D print.
• Support material—which fills gaps and spaces in the part during printing,

Storage

Materials used for producing 3D prints with J850/J835 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
• When not in use, keep material cartridges tightly sealed to prevent
• Store material cartridges indoors, in a dry area with adequate ventilation,
• Signs of premature polymerization in material cartridges include bulging,
• Make sure that material cartridges are stored in accordance with all local

Shelf Life

Materials used for producing 3D prints 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
