Abstract: A method for producing a tridimensional structure comprises: (a) ejecting an object material through a first print head; (b) ejecting a first pre-supporting material through a second print head; (b′) ejecting a second pre-supporting material through a third print head, the pre-supporting materials comprising liquid components which form a solid supporting material when brought together; (c) radiation curing the object material; steps (a) to (c) are repeated several times in order to form the tridimensional structure layer by layer, and the object material and the supporting material comprise at least one common boundary surface; and (d) removing the cured supporting material by treatment with an aqueous medium. The supporting material is suitable for supporting overhanging components and structures located above hollow spaces. The use of a supporting material cured by a different mechanism than the object material prevents undesirable interactions between the object material and the supporting material during curing.

Abstract: A method for producing a tridimensional structure by 3D printing comprises: (a) ejecting an object material through a first print head, the object material comprising a radically curable compound and a photoinitiator; (b) ejecting a supporting material through a second print head, the supporting material comprising a cationically polymerizable compound and a photoacid generator; (c) radiation curing the object material and the supporting material; steps (a) to (c) are repeated several times in order to form the tridimensional structure layer by layer, and the object material and the supporting material comprise at least one common boundary surface; and (d) removing the cured supporting material by treatment with an aqueous medium. The supporting material is suitable for supporting overhanging components and structures located above hollow spaces.
