2Overview
Processed with SAF™ technology on the Stratasys H350™ 3D printer,Stratasys SAF PA12 delivers production-grade plastic parts for highvolume demands — driving new areas of business growth. Stratasys
SAF PA12 enables a high nesting density while maintaining high partconsistency to deliver production-level yields.

Mechanical Properties
The mechanical data in this datasheet were generated from parts in the “Full Standard Test Build” (Figure 1) built
using Stratasys SAF PA12, processed using SAF™ technology on the Stratasys H350. The “Full Standard Test Build”
is robust in that it tests both mechanical and geometric performance from within the same build. However, the build
itself has been modified to focus on specific customer PA12 requests (more accuracy, less mechanical datacompared to the High Yield PA11 FSTB).

Comprehensive Sample Sizes
The mechanical data come from over 750 tensile specimens (>350 in X/Y and >350 in Z), 90 flexural specimens(60 in X/Y and 30 in Z) and 540 impact specimens (360 in X/Y and 180 in Z), all printed in 22 builds from 5 different
printers split between 2 locations. Each build has 18 tensile specimens in the ZX orientation and 20 collectively inthe X and Y orientations.

4Standard Build and Test Practices
The build was prepared using GrabCAD Print Pro. The parts were built with standard machine settings following
the H350 installation process. The material consisted of 70% used and 30% virgin powder by mass, as per
PA12 H350 guidelines. Post processing of parts followed H350 guidelines including 24 hours cooling after
removal from the machine, manual breaking out, and powder removal via automated bead blasting. No further
post processing was performed. All testing was based on ASTM or ISO standards where applicable. All parts
were preconditioned according to ASTM D618-13.

5Full Build Characterization
The “Full Standard Test Build” contains a wide spread of ASTM D638-14 Type 1 tensile specimens in threeorientations: ZX (upright), XZ (on end) and XY/YX (laid flat).
The 20 XY, XZ and YX specimens (highlighted in Figure 2) and the 18 ZX specimens (highlighted in Figure 3) arecomprehensively placed within the test build, allowing full characterization of the build volume and real confidence inthe mechanical performance of the H350.
The test build also contains geometric property specimens, physical property specimens and give-away parts at apart nesting density of 12%.

Geometric Properties
The following geometric data were generated from the same builds as the previous mechanical data, madepossible by the H350’s ability to make both strong and accurate parts with the same settings. All parts were built
and post-processed using the same standard methods as stated in the mechanical section. All parts weremeasured with a Aberlink EXTOL 370 CMM. The geometric data comes from a geometric “star” (nominal range
from 5 to 80mm). The placement of these star parts can be seen in Figure 4.
