Objet500 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

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.

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.
If printing materials are not in their sealed cartridges, make sure to shield
