The SLS Nylon(PA12) (plastic) objects printed through FacFox are created from a fine polyamide powder, more commonly known as plastic.
The material is both solid and flexible. Nylon PA12 (Plastic) is great for both experienced professionals and beginning designers because of its high precision and low cost. The material is white, granular, and somewhat porous.

Not Suitable For
Fine-detail models with smooth surfaces, Large models
This material is incredibly versatile, and can be used for a wide variety of applications, from iPhone cases to jewelry, remote controlled quadcopters to wearable bikinis. When thin, it's flexible enough for hinges and springs. When thick, it's strong enough for structural components.
Thicker models are more difficult to bend
Flexibility depends on the structure and design of the model. The thicker you make something, the less flexible it will be. A spring made with 1mm wire will compress and elongate rather easily. A spring made with 3mm thick will take a bit more effort, and won’t compress if you drop it from a few feet.
Thicken your engraved/embossed text to make it easier to read
Although 0.4mm details will show up in this material, we find that text raised at least 0.6mm shows up most clearly. If you want crisper text or embossed details, try bumping the thickness up to 0.6mm.
Min Supported Wall Thickness
A supported wall is one connected to other walls on two or more sides.
Min Unsupported Wall Thickness
An unsupported wall is one connected to other walls on less than two sides.
Min Supported Wires
A wire is a feature whose length is greater than five times its width. A supported wire is connected to walls on both sides.
Min Unsupported Wires
A wire is a feature whose length is greater than five times its width. An unsupported wire is connected to walls on less than two sides.
Min Embossed Detail
A detail is a feature whose length is less than twice its width.
The minimum detail is determined by the printer's resolution.When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details that are too small can also be smoothed over in the polishing process.
To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.
Min Engraved Detail
A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.
Clearance is the space between any two parts, walls or wires.
To ensure a successful product, make the clearance between parts, walls, and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.
Min Escape Holes
Escape holes allow unbuilt material inside hollow products to be removed.
Normally you don't need to consider this, our technician will add escape holes before printing.
When products contain hollow cavities, they are often filled with powder/liquid even after they are removed from the build tray. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it.
Interlocking/moving or enclosed parts?
Sometimes the interlocking/moving parts can't be printed, since the supports inside the cross section can't be removed.
Require Support Material?
Because each layer needs to build off the last, for some material, angles of more than 45 degrees generally require supports to be printed along with the design. Supports are not inherently detrimental for your design, but they do add complexity to the printing process and lead to less smooth finish on overhanging parts.

Material Spec Sheet
SLS Nylon (PA12) is 3D printed using SLS (Selective Laser Sintering) technology.
Laser sintering is used to build your design with this material.
The models are printed layer by layer by a laser that draws thin lines in the powder, which melts and bonds it together in order to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller. The printer has a print chamber that is heated to just below the melting point of the powder; the laser beam adds the extra energy to melt the powder, forming a solid model. After a print job is finished, the result is a big block of heated powder with the printed models contained inside.
