Protein-based resins for additive manufacturing

A photopolymerizable protein resin, comprising:

• a water soluble acrylated protein or the water soluble methacrylated protein at a concentration of between 1 and 45 wt %;
• a photosensitizer or photoradical generator at concentration of between 0.00748 and 10 wt %
• acrylated or methacrylated comonomer in water at a concentration of between 0 and 50 wt %;
• and
• a radical at a concentration of between 0 and 10 wt %.

A bioplastic structure, comprising:

• a photopolymerizable protein resin that has been cured by exposure to light in the range of 200 to 1000 nm, wherein the photopolymerizable protein resin comprises:
• a water soluble globular protein at a concentration of between 1 and 45 wt %
• acrylated or methacrylated comonomer at a concentration of between 0 and 50 wt %;
• a photosensitizer or photoradical generator at concentration of between 0.00748 and 10 wt %;
• and
• a radical at a concentration of between 0 and 10 wt %.
