Printing Materials
Stratasys ȱ printers ȱ produce ȱ models ȱ by ȱ jetting ȱ thin ȱ layers ȱ of ȱ printing ȱ
materials ȱ on ȱ the ȱ build ȱ tray, ȱ until ȱ the ȱ complete ȱ model ȱ is ȱ formed. ȱ Two ȱ types ȱ
of ȱ material ȱ are ȱ used ȱ in ȱ this ȱ process:
•
Model ȱ material—which ȱ makes ȱ up ȱ the ȱ finished ȱ model
•
Support ȱ material—which ȱ fills ȱ gaps ȱ and ȱ spaces ȱ in ȱ the ȱ model ȱ during ȱ
printing, ȱ and ȱ is ȱ removed ȱ after ȱ printing
Storage
Materials ȱ used ȱ for ȱ printing ȱ models ȱ with ȱ Stratasys ȱ printers ȱ are ȱ made ȱ of ȱ
resins, ȱ which ȱ are ȱ composed ȱ of ȱ reactive ȱ monomers ȱ and ȱ oligomers. ȱ
Although ȱ printing ȱ materials ȱ are ȱ supplied ȱ in ȱ sealed, ȱ UV Ȭ proof ȱ cartridges, ȱ
care ȱ must ȱ be ȱ taken ȱ when ȱ storing ȱ and ȱ handling ȱ them. ȱ Follow ȱ these ȱ
guidelines ȱ to ȱ protect ȱ operators ȱ and ȱ the ȱ environment, ȱ and ȱ to ȱ ensure ȱ
optimum ȱ results. ȱ
•
To ȱ ensure ȱ product ȱ stability, ȱ do ȱ not ȱ allow ȱ these ȱ materials ȱ to ȱ come ȱ into ȱ
contact ȱ with ȱ metal. ȱ Plastics ȱ made ȱ from ȱ monomer Ȭ soluble ȱ substances ȱ
(such ȱ as ȱ polystyrene ȱ or ȱ polyvinyl ȱ chloride) ȱ are ȱ not ȱ suitable ȱ for ȱ storing ȱ
PolyJet ȱ printing ȱ materials.
•
When ȱ not ȱ in ȱ use, ȱ keep ȱ material ȱ cartridges ȱ tightly ȱ sealed ȱ to ȱ prevent ȱ
contamination, ȱ the ȱ effects ȱ of ȱ exposure ȱ to ȱ UV ȱ radiation, ȱ and ȱ accidental ȱ
spillage. ȱ
•
Store ȱ material ȱ cartridges ȱ indoors, ȱ in ȱ a ȱ dry ȱ area ȱ with ȱ adequate ȱ
ventilation, ȱ between ȱ 16–27 ȱ degrees ȱ Celsius ȱ (60–81 ȱ degrees ȱ Fahrenheit). ȱ
If ȱ exposed ȱ to ȱ heat ȱ or ȱ flames, ȱ cartridges ȱ might ȱ burst ȱ or ȱ ignite.
•
Signs ȱ of ȱ premature ȱ polymerization ȱ in ȱ material ȱ cartridges ȱ include ȱ
bulging, ȱ leaking, ȱ the ȱ emission ȱ of ȱ heat, ȱ and ȱ unusual ȱ odor. ȱ Exposure ȱ to ȱ
heat ȱ can ȱ cause ȱ resin ȱ to ȱ gel ȱ in ȱ the ȱ cartridge.
•
Make ȱ sure ȱ that ȱ material ȱ cartridges ȱ are ȱ stored ȱ in ȱ accordance ȱ with ȱ all ȱ
local ȱ regulations ȱ and ȱ other ȱ applicable ȱ requirements.
Shelf Life
Materials ȱ used ȱ for ȱ producing ȱ models ȱ have ȱ a ȱ limited ȱ shelf ȱ life. ȱ The ȱ expiry ȱ
date ȱ on ȱ the ȱ label ȱ is ȱ valid ȱ when ȱ properly ȱ stored ȱ in ȱ an ȱ undamaged, ȱ
unopened ȱ cartridge. ȱ Always ȱ rotate ȱ your ȱ stock, ȱ so ȱ that ȱ the ȱ cartridge ȱ with ȱ
the ȱ earliest ȱ date ȱ is ȱ used ȱ first.
Exposure to
Light
If ȱ printing ȱ materials ȱ are ȱ not ȱ in ȱ their ȱ sealed ȱ cartridges, ȱ make ȱ sure ȱ to ȱ shield ȱ
them ȱ from ȱ sunlight ȱ and ȱ other ȱ sources ȱ of ȱ UV ȱ radiation, ȱ such ȱ as ȱ fluorescent ȱ
and ȱ mercury Ȭ vapor ȱ lights. ȱ Exposure ȱ to ȱ UV ȱ radiation ȱ causes ȱ an ȱ increase ȱ in ȱ
viscosity ȱ and, ȱ eventually, ȱ solidification.
