METHOD TO FORM A FIRST AND A SECOND THREE-DIMENSIONAL OBJECTS FROM A FIRST AND A SECOND SOLIDIFIABLE MATERIALS BEING CAPABLE OF SOLIDIFYING UPON IMPINGEMENT THEREON OF ELECTROMAGNETIC RADIATION

摘要

The present invention relates to a method to form a three-dimensional object including a first and a second component (01, 02) from a first and a second solidifiable materials (5a, 5b) being capable of solidifying upon impingement thereon of electromagnetic radiation, the method comprising: o providing a main digital image of the three dimensional object; o introducing said first and said second solidifiable material (5a, 5b) in a first and a second chamber (2a, 2b), respectively; o elaborating the main digital image dividing it in a first digital image corresponding to the first component and a second digital image corresponding to the second component; o associating the first component to the first chamber and the second component to the second chamber; o irradiating by means of an electromagnetic source (6) a layer of said first and/or said second solidifiable material (5a, 5b), according to a given pattern, in order to selectively solidify the layer of the first and/or the second solidifiable material; o repeating the process for a plurality of layers to form the first and the second components (01, 02) of the three dimensional object; o while repeating the process, forming the first and the second components in parallel, by irradiating both chambers at the same time, or by alternating the irradiation from the first to the second chamber and vice versa.
