PRINT APPLICATOR INSTALLATION AND REMOVAL
The
print applicator
is on a rail system inside the print chamber, above the material delivery module (MDM). The applicator
process combines elevator and applicator movements to apply material to the top of the part so that the next layer can be
printed. The applicator, which contacts the material, can be removed from the ProX 800. The applicator should be kept with the
MDM so that when the material is changed, the applicator remains with the material that it has been in contact with.
NOTE: the print applicator tabs are delicate . The tabs are called out in illustration #3 below . Extra care should be
taken to prevent damage to them . If the tabs are damaged, the applicator calibration process will not perform
properly, resulting in print failures . In this case, the applicator tabs will need to be replaced . If the applicator
itself is damaged, it will need to be replaced .
