The final energy adjustments on the MJF printing process are a key element to cover for the
known machine to machine variabilities. MJF 3D printers need to be energy calibrated to fine
tune part quality and, currently, it uses a job with seven levels of the same parts. In
each level, the printer changes the energy delivered by the fusing lamps and, after printing,
the user chooses the level with the best part quality. The energy corresponding to that level
is then applied to the printer as a standard to print the following production jobs.
