And yield strength using ASTM D638-14 horizontally-oriented Type I and IV geometries. Tensile strengths of 61.6 and 60.9 MPa were observed for Type IV and Type I, respectively. Check:Tensile component geometry is equivalent to the desired printed component geometry.
Anisotropic mechanical property variance between ASTM D638 This paper utilizes a large pool of 47 user-assembled 3-D printers to quantify the mechanical property variations of ultimate tensile strength (UTS) and yield strength of FFF printed components using ASTM D638-14 horizontally-oriented Type I and IV geometries for poly lactic acid (PLA).

How to Perform an ASTM D638 Plastic Tensile Strength TestASTM D638 is one of the most common plastic strength specifications and covers the tensile properties of unreinforced and reinforced plastics. This test method uses standard dumbell or dogbone shaped specimens under 14mm of thickness. A universal testing machine (tensile testing machine) is needed to perform this test.

Potential of distributed recycling from hybrid Sep 01, 2020 · ASTM D638 Type 4 standard tensile bars  molds were fabricated with a Lulzbot TAZ 6 open source 3-D printer (Aleph Objects, Loveland CO) with 2.85 mm PC filament (Gizmodorks, Temple City, CA).The PC molds were then covered in an aluminum tape to give its internal faces a smooth molding surface and increase its lifespan.
Validating Isotropy in SLA 3D Printing FormlabsWe used a tensile tester to measure the differences between maximum strength and Youngs modulus in FDM and SLA prints. In order to collect the whole spectrum of angles, we printed five ASTM D638 defined type IV tensile bars in 15 degree intervals from 0 (flat relative to the XY plane) to 90 degrees (straight up and down).

If your sample is a sheet or film less than 1.00 mm thick, it should be tested to ASTM D882 . While it provides similar results to ISO 527-2 , ASTM D638 is not considered technically equivalent due to differences in specimen size and test requirements.
