Learn methods and guidelines for using stereolithography (SLA) 3D printed molds in the injection molding process to lower costs and lead time. Between each displacement step, stiffness may change due to P-delta, large-displacement and/or nonlinear material behavior effects. The frame element uses a general, three-dimensional, beam-column formulation which includes the effects of biaxial bending, torsion, axial deformation, and biaxial shear deformations. This approach represents the material in the cross section as discrete points, each following the exact stress-strain curves of the material. Charles Camp for
