Abstract
The disclosure describes a polymerizable liquid that includes a reactive oligomer and a reactive monomer. The polymerizable liquid is an energy polymerizable liquid hardenable by a single reaction mechanism forming a photoplastic material. The disclosure further describes a method of producing the photoplastic material and articles that can be made from the photoplastic material.

A free radical polymerizable liquid, the free radical polymerizable liquid comprising:
- a reactive oligomer, the reactive oligomer being at least one (i) a multi-functional methacrylate oligomer, and (ii) a multi-functional acrylate oligomer;
- and
- a reactive monofunctional monomer, the reactive monofunctional monomer being at least one of (i) a monofunctional N-vinyl monomer, (ii) a monofunctional vinyl ether monomer, (iii) a monofunctional vinyl ester monomer, (iv) a monofunctional vinylamide monomer, (v) a styrene monomer, (vi) a monofunctional acrylamide monomer, (vii) monofunctional (meth)acrylate monomer, (viii) a cyanoacrylate monomer, (ix) a monofunctional vinyl carbonate monomer, (x) a monofunctional acryloyl monomer, and (xi) a monofunctional vinyl carbamate monomer,
- wherein a molar bond ratio of the reactive ethylenically unsaturated groups of the reactive monofunctional species to the reactive ethylenically unsaturated groups of the reactive multi-functional species is at least 10:1,
