Abstract:
1. A method for producing a solidified 3-D object comprising: (1) forming a first layer comprising a photocurable composition containing at least one photocurable monomer, at least one photoinitiator, at least one glycol or diol, and reactive particles comprising a crosslinked elastomeric core and a shell of reactive groups on an outer surface of the crosslinked elastomeric core wherein the crosslinked elastomeric core comprises a crosslinked polysiloxane material and wherein the reactive groups are epoxy groups, ethylenically unsaturated groups or hydroxy groups; (2) exposing the first layer to actinic radiation to form a hardened first layer; (3) forming a second layer comprising the photocurable composition on top of the hardened first layer; (4) exposing the second layer to actinic radiation to form a hardened second layer; and (5) repeating steps (3)-(4) as needed to produce the solidified 3-D object.
