Printing Materials
Connex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Connex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
op
timum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
Objet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mayburstorignite.
• Signsofprematurepolymerizationinmaterialcartridgesmay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.
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.
