Abstract In the present scenario, additive manufacturing is considered to produce functional parts in low volume. This investigation deals with effect of process parameters viz., raster angle, orientation and type surface on dimensional accuracy, flatness, shrinkage roughness VeroBlue RGD840 rigid opaque materials, produced by polyjet process. A Taguchi array ( L 8 ) used design experiment. Sur...

Abstract We introduce the notion of symplectic flatness for connections and fibre bundles over manifolds. Given an $$A_\infty $$ A ∞ -algebra, we present a condition that enables twisting differential complex associated with -algebra. The arises from -algebra forms cons...
