Residual Stresses in Layered Manufacturing

  title={Residual Stresses in Layered Manufacturing},
  author={Alexander Nickel and Denise Barnett and Gabriele Link and Fritz B. Prinz},
Layered Manufacturing processes accumulate residual stresses during material build-up. These stresses may cause part warping and layer delamination. This paper presents work done on investigating residual stress accumulation and part distortion of Layered Manufactured ar-tifacts. A simple analytical model was developed and used to determine how the number of layers and the layer thickness influences part warping. Results show that thin layers produce lower part deflection as compared with… CONTINUE READING
