Additional Info

Aramid Fiber is a Kevlar® based, specialized Continuous Fiber known for its energy absorption and extreme toughness. When laid into Onyx or another Composite Base material, it yields impact-resistant parts that are nearly immune to catastrophic failure (fracture). It’s perfect for use in parts that are in demanding environments or are subject to repetitive loading.

Min Supported Wall Thickness A supported wall is one connected to other walls on two or more sides.	0.4 mm
Min Unsupported Wall Thickness An unsupported wall is one connected to other walls on less than two sides.	0.4 mm
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.	0.8 mm
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.	0.8 mm
Min Hole Diameter The accuracy of a hole not only depends on the diameter of the hole, but also on the thickness of the wall through which the hole is printed. The thicker the wall section, the less accurate the hole becomes. Through holes must also allow for line-of-sight clearance to ensure all material is cleared during post-processing.	0.8 mm
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.	0.2 mm
Min Engraved Detail A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.	0.2 mm
Min Clearance 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.	0.4 mm
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.	10 mm
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.	Yes

Material Spec Sheet

FDM Aramid Fiber (Kevlar) is 3D printed using FDM (Fused Deposition Modeling) technology.

Fused Deposition Modeling is used to build your design with this material.

The principle is simple. You can compare it with a hot glue gun into which you put sticks of glue. The glue is heated up until it melts and is then pushed through a fine nozzle in the front of the glue gun.

In an FDM printer, a long plastic wire is used in place of glue. It is fed from a spool to the nozzle where the material is liquefied and ‘drawn’ on the platform where it immediately hardens again. The nozzle moves to drop the material at the correct location, drawing your model line by line. When a layer is drawn, the platform lowers by one layer thickness so the printer can start with the next layer.

When your model contains overhanging sections, the printer needs to build supporting material. Since the material of the model cannot be deposited in the air, the support material prevents it from falling down. This support material is fed through another nozzle.

Afterward, when the model is put into a bath with special soap, the support material dissolves.
