OVERVIEW

Finite element analysis (FEA) is a computer-based method of analyzing and simulating the behavior of components under a variety of conditions, including force, temperature, vibration  and  motion.  FEA  calculates  displacements, strains, and stresses under internal and external loads. These predictions confirm if a design is suitable or if modifications are required to prevent failure.

FEA results are presented as on-screen, digital models with color mapping for a visual depiction of the effects of applied conditions. These models may also show
the resulting change to a component’s geometry as it deforms under the applied load.

To bring FEA results into the real word, PolyJet™ 3D Printers create physical models
that retain the FEA color mapping.  Rather than interpreting results from a computer screen, designers and engineers can visualize the analysis with models that are hand-held. The results can be printed in an “as-designed” or “load-deformed” state.

Common applications for 3D printed FEA results include:

• Design verification
• Failure analysis
• Material selection
• Design review meetings
• Marketing presentations
