Abstract

One of the core concepts in additive manufacturing is to have accurate powder deposition on bed

with uniform duration throughout the print job. The inaccuracy in job layer duration arising when

some layers take more or lesser than the recommended value, often results in bad part quality issue

or indicate issues with print hardware components.

This disclosure describes a method for improving Print Quality (PQ) and reduce unplanned

downtime (due to sub-system failure) by looking at layer time for the print cycles and figuring if

they are running off the prescribed limits for the material used. Based on this information the

erroneous machines can be inspected for diagnosing fault. Analysis by services and support (using

the information from the cases flagged using this technique) suggests the dominating cause to be

hard drive failures (replacing which solves the problem), though there can be other reasons as well.
