The invention relates to, inter alia, an installation including a first computing infrastructure with a web server which is configured to provide a user interface by means of which a component can be selected by a user logged into the web server, and a second computing infrastructure which can be connected to a plurality of additive manufacturing devices in a plurality of local networks for operating the additive manufacturing devices. The first computing infrastructure sends to the second computing infrastructure instructions which prompt an additive manufacturing device to additively manufacture the selected component in a multiplicity of layers, and a manufacturer identifier which references an additive manufacturing device associated with the logged-in user. The second computing infrastructure receives the instructions and the manufacturer identifier and instructs the additive manufacturing device referenced in the received manufacturer identifier to additively manufacture the selected component according to the received instructions.
