While HP’s 3D Printing technology aims to be used for mass manufacturing applications, there are some high standards markets in which there are still some barriers that makes it not viable. There are several reasons and one is the capability of the machine of delivering consistently good parts. Depending on the application, the definition of good part may change, thus the requirements will be different depending on the application purpose. There is the certainty that there are further calibrations of some of the subsystems of the printer that can reduce the variability of some attributes of the outcome of the printer. HP has already worked on which are the subsystems that have a potentially higher impact on the part quality and which tests should be done to understand and quantify it. The main goal of this study is to check the most common part requirements after doing different calibrations (defined by HP’s R&D group) of different subsystems of the printer. In order to enable this comparison, a brand-new database has been developed by the student to link the part quality attributes with the settings applied in each one of the different calibrations. Moreover, data coming from the internal sensors of the machine has also been linked with the part quality attributes and the printer settings. Matching internal sensors values with part quality can provide a further understanding on how the printing process works, what gives to this database an added value that will be leveraged by the HP’s Research and Development department. Another important part of the study is the standardization of how the most common part requirements can be evaluated. Some attributes, as the dimensional accuracy, are continuous and objective metrics. Others, like the look and feel of the parts can be harder to evaluate objectively, although they usually are a very important requirement for lots of applications. In the study, this has been solved designing parts to objectively evaluate the most common look and feel defects with a 3D scanner. Finally, the study of the impact in the part quality of the different adjusted knobs concludes which is the subsystem calibration of the printer that delivers a better improvement of the measured part quality attributes.
