Test results for HP 3D HR PP enabled by BASF
Table 6 shows the values that were obtained for HP 3D HR PP enabled by BASF in the HP Jet Fusion 5200 Series 3D Printing Solution, with PP Balanced print profile and Type I tensile specimens, following the ASTM D638 standard. In this case, heat deflection temperature was characterized in a separate job configured for this purpose using a standard bar specimen according to the ASTM D648 standard.

i. Based on internal testing and measured using the HP Half_Commercial_Datasheet_Job. Results may vary with other jobs and geometries.
ii. Using HP 3D HR PP enabled by BASF material, 20% refresh ratio, Balanced print profile, natural cooling, and measured after bead-blasting with glass beads (70–110 µm) at 5-6 bars.
iii. Following all HP-recommended printer setup and adjustment processes and printheads aligned using semi-automatic procedure.
iv. Tensile strength typical variation (95% of parts) falls within the 28-32 MPa range, while tensile modulus values remain within the 1360 to 1840 MPa range.
v. Tensile test type I specimens measured with a pulling speed of 5 mm/min to comply with ASTM D638 test standards.
vi. Using the Izod test method A with notched @ 3.2 mm specimen according to the ASTM D256 standard.
vii. Using a standard bar specimen measuring 5” x ½” x ¼” in accordance with ASTM D648.
