| Abstract Scope |
Fused deposition modeling (FDM) has been a rapidly growing 3D printing technology for polymer-based products. Additive manufacturing technologies have seen an expansion into printing various polymers, including acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) on various printers and print orientations. In this study, we evaluate the tensile strength characteristics of FDM printed ABS and PLA parts. Specimens with a dog bone geometry were printed on both an entry-level FlashForge 3D printer and a Stratasys F170, using the ASTM D638 standard test method. A flat build orientation was used with varying raster orientations of 0, 45 or 90 degrees on the build plate. An Instron Tensile Testing machine was used to evaluate the stress-strain characteristics of each specimen and determine yield and tensile strength of the parts. Results showed that there was a negligible effect on the strength of the material for the different raster orientations. |
