Določitev temperaturno odvisne poti dodajanja materiala

Kovšca, Dejan (author), Starman, Bojan (author), Mole, Nikolaj (author)

Predstavljen je algoritem za določitev najprimernejše temperaturno odvisne poti dodajanja materiala, oz. t. i. "3D tiska", na podlagi metode končnih elementov (MKE). Izračunana pot, v primerjavi s konvencionalnim enosmernim ali dvosmernim tiskom, rezultira v enakomernejšem temperaturnem polju po območju izdelka, nižjih temperaturnih gradientih in posledično manjših deformacijah ter zaostalih napetostih v končnem izdelku.

• Title: Temperature-based path identification for additive manufacturing

Abstract

An algorithm for identification of temperature-based path for additive manufacturing (AM) is presented. The algorithm is based on the finite element method (FEM). The resulting welding path, compared to conventional path, results in a more homogenized temperature distribution, lower temperature gradients and consequently lower distortions and residual stresses in the final product.
