Print Heads

Theconditionoftheprintheadsdirectlyaffectsthequalityofprinted

models.Tomaintainoptimumprinting,youshouldroutinelytesttheprint

heads,andcalibratethemtothebestworkingconfigurationpossible.You

dothisbyrunningtheHeadOptimizationwizard.

Duringtheoptimizationprocess,32samplesareprintedonthebuildtray

Aftercarefullyweighingeachofthem,youentertheweightinthewizardʹs

data‐entryscreen.Thewizardusesthisdatatooptimizetheheads.

If,duringtheoptimizationprocess,thewizarddeterminesthataprinthead

isfaulty—orthatitisnegativ elyaffectinglayeruniformitywiththecurrent

headconfiguration—th

ewizardinstructsyoutoreplaceit.Ifthishappens,

youcancontinuethewizard(toreplacetheprinthead)orabortthewizard

(toreplacetheheadatanothertime).

To test and calibrate the print heads:

1. Prepare—

• isopropanol(IPA—isopropylalcohol)orethanol(ethylalcohol)

• disposablecleaninggloves

• anObjet‐suppliedcleaningclothorequivalent

• amirror

• thescalesuppliedbyObjetforuseintheWeightTest

Run the Head Optimization Wizard whenever the condition of print heads is

negatively affecting the quality of printed models, or if you suspect that there

is a problem with one or more of the print heads.
