Post-Printing Treatment for Models Made with VeroClear
ModelsmadewithVeroClear(RGD810)haveaslightyellowtintwhen
removedfromtheprinter.Thisisespeciallytrueformodelsprintedwitha
glossyfinish.Theyellowtintfadesnaturallyovertime,butyoucangreatly
acceleratethisprocessbyusingasuitablephotobleachingtreatment.
Asarule,bestclarityisachievedwhenpartsareprintedwithamattefinish,
andtreatedasexplainedbelow.
Photobleachingmodelsinvolvesexposingthemtolight.Toachievehighly
controlledandpredictableresults,aprofessionalilluminationchamberis
recommended.However,adequateresultsmaybeobtainedusingordinary
desklampsfittedwithsuitablefluorescentelements.
