How to correlate printed part quality defects to Nozzle Health Status or Part Quality Diagnostic The Mono Bar corresponds to Diagnostic A of the Print Quality Diagnostic, and the Color Bar to Diagnostic D of the Print Quality Diagnostic: ● Bright Fusing: Missing nozzles will appear as troughs or divots in the part in the direction of the print carriage. May also appear as missing color, since this agent is used to affix color to the outside of parts. Strength of small features may be affected, if nozzles are lined up in that region. ● Detailing Agent: Missing nozzles can appear on parts in many ways. Some possibilities include overfusing or thermal bleeding, washed out colors, or dimensional mismatches in cases such as fitting two parts together or the inability to clear out small holes. ● Fusing Agent: There is significant margin in the system to compensate for missing nozzles of this type, but possible impacts would be: a decrease in internal strength and/or pockets of unfused material trapped on the inside of a part. ● Colors (KCMY): Only cosmetic appearance will be affected by color nozzles being out, and always along the axis of the print carriage. Symptoms include color non-uniformity or completely missing color. Printhead troubleshooting Use these instructions to troubleshoot print quality defects observed on a Quality Diagnostic Page.

How to correlate printed part quality defects to Nozzle Health Status or Part Quality

Diagnostic

The Mono Bar corresponds to Diagnostic A of the Print Quality Diagnostic, and the Color Bar to Diagnostic D of the

Print Quality Diagnostic:

●

Bright Fusing: Missing nozzles will appear as troughs or divots in the part in the direction of the print

carriage. May also appear as missing color, since this agent is used to aﬀix color to the outside of parts.

Strength of small features may be aﬀected, if nozzles are lined up in that region.

●

Detailing Agent: Missing nozzles can appear on parts in many ways. Some possibilities include overfusing or

thermal bleeding, washed out colors, or dimensional mismatches in cases such as ﬁtting two parts together

or the inability to clear out small holes.

●

Fusing Agent: There is signiﬁcant margin in the system to compensate for missing nozzles of this type, but

possible impacts would be: a decrease in internal strength and/or pockets of unfused material trapped on

the inside of a part.

●

Colors (KCMY): Only cosmetic appearance will be aﬀected by color nozzles being out, and always along the

axis of the print carriage. Symptoms include color non-uniformity or completely missing color.
