The researcher of oak mountain lab and laborious laborious carry a company to cooperate then, print the mould of odd one side of tool of a duplicate and prefab concrete through 3D, showed the potential that uses much material and second birth composite material in large-scale applying.

This group adds material to make in large area system of an of reinforced material added on the machine, an extruder is used to print a variety of data in making its can be built in compose. Inside 7 hours, large 3D printer produced the pattern of a 400 pounds, length is 10 feet, increase by reclaiming carbon fiber thermoplastic plastic with synthesis expanded plastics is made. Those who use much material and second birth composite material is large-scale print the cost that predicts to will reduce a mould, offer an opportunity to print the structure that has small qualitative core and custom-built character. Relevant personnel says: "It is OK to be printed through much material the mechanical reaction with new implementation, mix in the soft hard section inside a component for example fight concussion structure. "　 　 ORNL and laborious laborious carry a company to cooperate then, use large area to added material production machine to print by what reclaim thermoplastic composite material and the 3D mould that synthesize bubble composition, the latent capacity in revealing much material to be in large-scale applying.
