SAF PA11 ECO 3D Material
Eco-friendly! PA11 is made from renewable resources that come from natural vegetable and castor oil source materials.
The process has a lower environmental impact from manufacturing the powder through to end of life of the products it makes.
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 geometric properties from within the same builds, highlighting the H350’s ability to produce both strong and accurate parts, with no compromise.

The SAF PA11 material can be delivered in many of the finishes we offer, which include Natural, Vibro Polished and Shot Peened. Here are a few examples of how the SAF PA11 material appears after undergoing our post processing finishes.



Which Material is right for you?
In the chart below you can compare the main mechanical properties of each materials. To make it easier to compare, we have given each value a rating out of 5 (0.5 increments). This can also be seen in the table below. You can toggle each material visibility on/off using the buttons on the right.

Benefits of using PA11 as a 3D Printed Material
Properties
Accuracy
★★★★★
Expected: 0.1mm or 0.1%
Guaranteed: 0.3mm or 0.3%
Repeatability
★★★★★
One of our most repeatable materials, perfect for batch production.
Strength
★★★★☆
Our strongest material in terms of tensile and impact resistance. See data below.
Flexibility
★★★★☆
Our most flexible polymer other than our rubberlike SLS TPU
Melting Point
★★★★☆
Great thermal resistance with a melting point of 190 degrees C
Resistance to Warping
★★★☆☆
Warping is almost non-existent with this material due to its flexibility, however, very rectangular geometries can shrink erratically.
Elemental and UV Degradation
★★★★☆
Great resistance to the elements can be used for outdoor products.
Chemical and Water Resistance
★★★★☆
Has great chemical and water resistance.

Wall Thickness
Though SAF PA11 ECO has the best mechanical properties, very thin-walled items can be brittle. If your dimensions are close to our recommended minimums, parts can be a more prone to breaking than SLS PA12 and MJF PA12 – we recommend making geometries a little thicker to take full advantage of the mechanical properties.
Pixel Stepping
Layer-like lines are visible on near vertical surfaces – these are not layer lines, but rather pixel lines from the print heads. These can be visible on smooth curves and parts with overhangs such as drafted surfaces.
Small Hole and Cavities
PA11 runs at a higher temperature than our other materials as a result we recommend that you pay careful attention to small hole and cavities in your designs and where possible use creative solutions to help these clear out in post-processing.

Design Guidelines, Maximums and Minimums

Max Print Size
This is the maximum size we can print a part in one piece
Express: 270 x 190 x 275mm
Economy: 270 x 190 x 275mm
Trade: 270 x 190 x 275mm

Min Wall Thickness
This is the minimum wall thickness we can guarantee to print. You are able to print under this guarantee at your own risk, however, prints under our guarantee are not covered for a free reprint if damaged.
Natural: 1mm
Shotpeen: 1.5mm
Polished: 2mm

Min Embossed Thickness
This is the minimum thickness a surface detail can be – this includes text and small intricate details. Note the thickness stroke width, not the width of the entire letter if referring to text.
Width: 0.5mm
height: 0.3mm

Min Engraved Thickness
This is the minimum thickness a engraved surface detail can be – this includes text and small intricate details. Note the thickness stroke width, not the width of the entire letter if referring to text.
Width (except shotpeen): 0.5mm
Width (shotpeen): 0.7mm
Depth: 0.3mm

Min Hole Sizes
This is the minimum diameter of a hole. As a rule of thumb, the longer the hole, the larger the diameter is required to prevent them from blocking with powder. It is best to avoid long and twisting holes as these are near impossible to clear the powder from post-print.
<2mm depth: 1mm
2-5mm depth: 2mm
5-10mm depth: 3mm
10mm+: at least 4mm
*Powder may not be able to be cleared out of holes longer than 30mm

Clearance
This is the minimum gap required between two separate parts that are designed to fit together, such as a case and a lid. This is the distance between surface faces – remember that this is each side meaning that you need to double this measurement if the whole part is interlocking. e.g. if a shaft is going into a hole, 0.15mm between surfaces means 0.3mm between diameters.
Tight fit: 0.15mm
Smooth fit: 0.25mm

Flat/Warpable Parts
Flat parts are prone to warping. Warping is where the part cools at different rates causing geometrical changes in the object. It is best to try to avoid these shapes where possible, or contact us to ask for advice.
Limitation: part dependant – ask us if you are concerned.

Min Sharp Angle
This is the minium angle recommended without a fillet or chamfer. Parts with sharp angles tend to get damaged in the print or post-processing stages. Anything sharper than the minimum angle is recommended to have a fillet.
Min Angle: 60°

Sharp Angle Fillet
Anything sharper than our minimum guaranteed angle is recommended to have a filleted edge. Filleted edges are far stronger than sharp edges and are less prone to damage in either post-processing or print stages.
Min Fillet: 1mm
