Zusammenfassung:	Additive manufacturing system for manufacturing a three dimensional object (10). A resin depositor (14) is present for depositing a layer of curable resin (6) on a first side (2a) of a foil substrate (2). The foil substrate (2) is supported by a transparent support plate (4), and a radiation source (5) is disposed for radiation curing the resin layer (6). A stage (12) is configured to hold a stacked arrangement of one or more cured resin layers representing at least in part the three dimensional object (10) and a positioning system is provided for relative positioning the foil substrate (2) and the stage (12). A masking screen (8) disposed substantially parallel to the resin layer (6) is present for blocking at least in part incident radiation on the resin layer (6) in correspondence with a cross sectional slice of the object (10).
