Thiol-acrylate polymers, methods of synthesis thereof and use in additive manufacturing technologies

An article made from a photopolymerized resin for additive manufacturing in an oxygen environment, the resin comprising:

• a crosslinking component;
• at least one monomer and/or oligomer;
• and
• a chain transfer agent comprising at least one of a thiol, a secondary alcohol, and/or a tertiary amine.
• wherein the resin is configured to react by exposure to light to form a cured material.
• wherein the chain transfer agent is configured to permit at least some bonding between a layer of resin previously cured and an adjacent, subsequently cured layer of resin, despite an oxygen-rich surface present on the previously cured layer of resin at an interface between the previously cured layer of resin and the subsequently cured layer of resin;
• wherein the article further includes further including a surface coating comprising an alkane.
