2Overview
Processed with SAF™ technology on the Stratasys H350 3D printer, Stratasys High Yield PA11 delivers production-grade plastic
parts for high-volume demands — driving new areas of business growth. Stratasys High Yield PA11 enables a high build density while
maintaining high part consistency to deliver production-level yields. Crucially, this datasheet includes both mechanical and geometricproperties from within the same builds, highlighting the H350’s ability to produce both strong and accurate parts, with no compromise.
In additive manufacturing, PA12 is the go-to material for prototyping. But in traditional high-volume production of end-use parts, PA11is much more widely used due to its higher ductility and higher impact resistance, as well as its suitability for a wider range of industry

Figure 1: The Full Standard Test Build

The mechanical data in this datasheet were generated from parts in the “Full Standard Test Build” (figure 1) built using Stratasys High
Yield PA11, processed using SAF™ technology on the Stratasys H350.
Comprehensive Sample Sizes
The mechanical data come from over 2000 tensile specimens (972 in X/Y and 1,080 in Z direction), 540 flexural specimens (360 in X/Yand 180 in Z) and 540 impact specimens (360 in X/Y and 180 in Z), all printed in 36 builds from 5 different printers split between theUK and Denmark. Each build has 30 tensile specimens in the ZX orientation and 27 collectively in the XZ and YX orientations.
Standard Build and Test Practices
The build was prepared using Materialise Magics and sliced using the Stratasys Build Processor. The parts were built with standard
machine settings following the H350 installation process. The material consisted of 70% used powder and 30% virgin powder bymass, as per H350 guidelines. Post processing of parts followed H350 guidelines including 24 hours cooling after removal from themachine, manual breaking out, and powder removal via automated bead blasting. No further post processing was performed. AllStratasys High Yield PA11 Data Sheettesting was to ASTM or ISO standards where applicable. All parts were preconditioned according to ASTM D618-13.

Full Build Characterisation
The “Full Standard Test Build” contains a wide spread of ASTM D638-14 Type 1 tensile specimens in three orientations: ZX (upright),XZ (on end) and YX (laid flat).
The 27 XZ and YX specimens (highlighted in figure 2) and the 30 ZX specimens (highlighted in figure 3) are comprehensively placed
within the test build, allowing full characterisation of the build volume and real confidence in the mechanical performance of the H350.
The test build also contains geometric property specimens, physical property specimens and give-away parts at a part build density ofStratasys High Yield PA11 Data Sheet12%.

The below histograms visualise the mechanical data presented in this datasheet.

6Geometric Properties
The following geometric data were generated from the same builds as the previous mechanical data, made possible by the H350’s
ability to make both strong and accurate parts with the same settings. The days of compromising are over.
All parts were built and post-processed using the same standard methods as stated in the mechanical section. All parts weremeasured with a Mitutoyo touch probe co-ordinate measuring machine (CMM).
The geometric data come from the same 36 builds across 5 machines split between the UK and Denmark, with each build providing
522 geometric data points from a wide range of XY locations and Z heights, split evenly through the X, Y and Z axes and covering anominal range from 5mm to 80mm.

Figure 4: The placement of the geometric specimens

Figure 5: The geometric specimens highlighted

The data come from 6 “Star” parts (in figures 4 and 5) built in a range of locations in the bed. This allows comprehensive
characterization of the build volume and real confidence in the consistency and accuracy of the geometric performance of the H350.
The geometric data are quoted as yields against an example tolerance of ±300µm (12 thou). This tolerance is applied to all

Stratasys High Yield PA11 Data Sheetmeasurements across all nominals and recorded as pass/fail. These pass/fails are then used to calculate an overall yield.
