The Digital Prototyping Laboratory, besides directly supporting some courses, it provides 3D printing services to the academic community, companies and institutions which have a protocol with IPL and still support research projects. It is equipped with a Z450 3D printer from 3DSystems which enables the development of prototypes for a formal evaluation that works with plaster-based materials with a useful area of 250x200x200 (mm). The DPL is not open to the public. In order for the services to be provided, a 3D (STL) file of the project to be printed must be sent to the email address: esad.cad@gmail.com. The student receives a quotation with the expenses of the consumables. Once the quotation is approved, the printed piece may be collected from the Accounting office, on a date to be defined.
