Abstract
A composite material includes biodegradable and/or renewable materials such as purified milk protein recovered as a byproduct in cheese making processes. The result is a material suitable for three-dimensional (3D) printing and extrusion based polymer processing, with improved properties but that is still environmentally friendly. Purified milk protein may be used to produce composite thermoplastic materials or resins. Additional chemical modification may improve the blending of purified milk protein.
Claims12
A 3-D printer filament comprising a thermoplastic material including:
- a first amount of polylactic acid;
- wherein the amount of polylactic acid is greater than 30 weight percent of
- the thermoplastic material;
- and a second amount of milk protein blended in the purified polylactic acid;
- wherein the milk protein is greater than 10 weight percent of the thermoplastic material and the polylactic acid is greater than the milk protein by weight percent.
A composition of a photocurable liquid resin comprising:
- a first amount of photopolymer resin;
- and
- a second amount of purified milk protein blended in the purified polylactic acid
- wherein the purified milk protein is between 0.001 and 20 weight percent.
