Abstract
A photopolymer development resin base is available for use with additive manufacturing units (for example, various three-dimensional printers) to create three-dimensional (3D) printed structures. In some embodiments, the resin formula can include a monomer, oligomer, diluent, photo initiator, deflocculents, wetting agents, and dispersants, with a limit on any photo-blockers, if present at all. The photopolymer development resin base functions as a binder precursor material with the capacity to accept solid powders or liquids for UV printing, which is not configured to print “as is.”
