Effect of selective laser sintering on stress relaxation in PA12/Wplyw selektywnego spiekania laserowego na relaksacje naprezen w PA12
Effect of selective laser sintering printing orientation (0[degrees], 45[degrees], 90[degrees]) on stress relaxation in PA12 was investigated. The results were highly consistent with the Maxwell-Wiechert model, as evidenced by the average values of the fit coefficients [[bar.[Chi].sup.2] = 0.00004 a...

Zusammenfassung: | Effect of selective laser sintering printing orientation (0[degrees], 45[degrees], 90[degrees]) on stress relaxation in PA12 was investigated. The results were highly consistent with the Maxwell-Wiechert model, as evidenced by the average values of the fit coefficients [[bar.[Chi].sup.2] = 0.00004 and [[bar.R].sup.2] = 0.996. By changing the printing orientation, anisotropy of rheological properties was achieved. Keywords: SLS, Maxwell-Wiechert model, stress relaxation, PA12. Streszczenie: Zbadano wplyw orientacji wydruku selektywnego spiekania laserowego (0[degrees], 45[degrees], 90[degrees]) na relaksacje naprezen w PA12. Uzyskano duza zgodnosc wynikow z modelem Maxwella-Wiecherta, o czym swiadcza srednie wartosci wspolczynnikow dopasowania [[bar.[Chi].sup.2] = 0,00004 oraz [[bar.R].sup.2] = 0,996. Zmieniajac orientacje wydruku uzyskano anizotropie wlasciwosci reologicznych. Slowa kluczowe: SLS, model Maxwella-Wiecherta, relaksacja naprezen, PA12. |
