Stratasys Objet desktop PolyJet 3D printers have a Log file that contains a time sequenced history of events of the printer activities. It contains error codes, calibrations, positions, and generally a snapshot of what the 3D printer is doing at the time. It is an invaluable troubleshooting tool and is often requested by Stratasys for analysis when diagnosing printer issues.
PolyJet 3D printing is a process that employs a UV-cured thin film, it has a very high resolution and can create stunning visual results. In general, PolyJet prints are superior when it comes to visual quality, but they suffer from one fatal flaw: the glossy PolyJet finish becomes a cloudy matte finish when it comes in contact with support material. Because of this, any surface that points downward is going to result in this rougher finish.
