supportsthesecapabilitieswhenpreparingtraysofmodelsforprintingon

thesesystems.

•Youcanstreamlineandeconomizetheprocessofproducingmodels:

❒ Printingmodelsmadefromdifferentmaterialsonthesamebuildtray

(“mixedtray”),inthesameprintjob,eliminatesthetime-consuming

needandexpenseofloadinganothermaterial,flushingthesystem,and

sendingaseparatejobtobeprinted.

❒ AlternatingprintjobsthatuseanyoftheModelmaterials(ormaterial

combinations)loadedsimilarlydoesnotrequirematerial

replacement—again,savingtimeandexpense.

•Youcanprintobjectswithcombinationsofbasicmaterials(digital

materials),enablingyoutochoosefromawiderangeofpossible

mechanicalproperties—fromflexibletorigid.

•Youcanprintparts(shells)ofthesamemodel—simultaneously—with

differentmaterials(ormaterialcombinations)

•Youcanprintobjectsthathavea“coating”madefromadifferentmaterial

thanthemainpartoftheobject.

•Youcanmixanycombinationofbasematerials,resultinginanextremely

widerangeofavailablecolors.

•Ifyoudesignatecolorsforpartsofamodelatthedesignstage(withCAD

themodelwiththedesiredcolors.

PolyJetStudioenablesyoutosplitmodelsintocomponentparts(“shells”)so

youcanisolate,manipulateandprintpartsofamodel.Then,youcanassign
