A method and apparatus for manufacture of 3D objects

摘要

The current three-dimensional object manufacturing technique relies on the deposition of a pseudoplastic material (104) in gel aggregate state. The gel flows through a deposition nozzle (116) because the applied agitation and pressure shears the bonds and induces a breakdown in the material elasticity. The elasticity recovers immediately after leaving the nozzle, and the gel solidifies to maintain its shape and strength.
