Реферат: Method and device for producing objects by a stereolithography device, which device comprises a vat (1) inside which there is provided a resin (11) intended to be cured, by projecting an image obtained by a light radiation (21) on the bottom of the vat (1). There is provided an adhesion platform (3) placed in contact with the resin (11), such to form a first layer of cured material adherent to the platform (3). There are further provided means for moving the platform (3), intended to move away/to approach the platform (3) with respect to the bottom of the vat (1). The method provides the following steps: a) placing the platform (3) at a distance from the bottom of the vat (1) equal to the thickness of the layer of the resin (11) to be cured, b) generating the light radiation, irradiating the resin (11) with it and consequently curing the layer of resin (11), c) moving away the platform (3) from the bottom of the vat (1) and detaching the layer of cured resin (11) from the bottom of the vat (1), d) forming the following layer of cured resin. The speed with which the platform (3) moves away/approaches is variable and it does not take null values, it being calculated depending on the amount of resin (11) to be cured and depending on the size of the resin layer (11) to be cured.
