Povećanje preciznosti izrade 3D štampanih delova primenom iterativne metode

Abstract

Veoma veliki porast upotrebe 3D štampe u poslednje dve decenije posledica je niza benefita koje ova proizvodna tehnologija nudi. U ovom radu analizirano je odstupanje geometrije štampanog modela u odnosu na CAD model. Izrada eksperimentalnog modela izvršena je metodom fuzionog taloženja filamenta (FDM) pri čemu je korišćen akrilonitril butadien stirol (ABS) materijal. Pokazano je kako se sa brojem iteracija odstupanje geometrije 3D štampanih modela u odnosu na CAD model smanjuje. U zaključku je dat pregled celokupnog procesa i preporuke u pogledu ograničenja upotrebe ove metode.

Large increase in the use of 3D printing or rapid prototyping in the last two decades is due to the many benefits that this manufacturing technology offers. In this article geometry accuracy of 3D printed parts is analyzed. For printing of the analyzed model Fused Deposition Modeling (FDM) method was employed. ABS material was used to create the specimens. The measurement results have shown that the dimensional accuracy of printed parts increases with the number of iterations. The overview of analyze and some recommendations in the sense of limitation in the application of this method are given as a conclusion of this paper.
