1. A removable calibration plate able to be positioned in a firing system for firing at least one power incident-radiation beam, which firing system belongs to an additive manufacturing apparatus,
the removable calibration plate comprising a sheet,
the sheet comprising an upper face intended to face toward the at least one power incident-radiation beam, the sheet bearing at least one reference marking and being intended to receive at least one test marking, and a lower face, which is distant from the upper face in a thickness direction of the sheet,
wherein the removable calibration plate comprises at least one etching layer to be etched by the at least one power incident-radiation beam,
wherein the at least one etching layer to be etched by the at least one power incident-radiation beam is secured to the upper face of the sheet and is opaque to visible light,
wherein the at least one etching layer to be etched by the at least one power incident-radiation beam is able to be destroyed locally by the at least one power incident-radiation beam in order to form the at least one test marking,
wherein the sheet is transparent to visible light, and
wherein the lower face of the sheet is depolished.
