SLS PA12 PA2200
Skin safe, food safe, repeatable and reliable, available in a range of colours.
SLS PA12 PA2200 3D Material
Our flagship offering, SLS PA12 (EOS PA2200) is widely regarded as the most versatile material in 3D printing.
Having been around since the dawn of Powder Bed Fusion, it is also arguably the most established material too. Combining excellent material properties with affordability, SLS PA12 is ideal not only for prototyping but also for batch and series manufacturing. Its applications span across diverse sectors including manufacturing, medical, aerospace, automotive, marine, and the arts.
One of the key advantages of SLS PA12 is its precision. It consistently delivers parts that closely match the STL file, minimising warping compared to MJF PA12 and avoiding the shrinkage issues associated with SLA or FDM technologies. In most cases, and as long as you model your parts by our design guidelines, what you send to the printer, is what you get back from the printer.

Appearance and Finish
The SLS PA12 material can be delivered in any of the finishes we offer, which include Natural, Vibro Polished, Shot Peened, Vapour Smoothed and Colours . Here are a few examples of how the SLS PA12 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 SLS PA12 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.
★★★★☆
Great material in terms of tensile and impact resistance. [data below]
Flexibility
★★★★☆
Great flexibility, suitable for snap fits.

3DPRINTUK observations while working with SLS PA12
Small holes
Smaller holes (below 10mm diameter) tend to be slightly elliptical on the upper side if printed up the Z axis. We run a few compensation processes to reduce this, however, this does not totally eliminate it, resulting in a slightly flat top to the circle.
Cleanliness
When a part is left in its natural finish, it can be prone to getting dirty easily. If this is an issue, we recommend polishing or shotpeening.
Small internal diameters
These can print fractionally undersized (around 0.2mm) for chunky parts with small holes below 10mm. This is due to the heat around the part causing thermal bleed and resulting in a fractionally larger melt pool than is desired.

Design Guidelines, Maximums and Minimums
Max Print Size
This is the maximum size we can print a part in one piece
Express, Economy and Trade : 286 x 186 x 300mm
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
