Additional Info

Advanced Polypropylene material for a wide range of applications. Thanks to the well-known performance of polypropylene, the powder delivers excellent chemical resistance, ductility and media tightness. Besides that, it’s an economically attractive alternative to commonly used PA12, making it an interesting choice to expand 3D printing applications and volumes.

Our enhanced formula goes one step beyond: In contrast to commonly used polyamides, Ultrasint® PP boasts excellent plasticity, higher elongation, durability, and low moisture absorption. The high rigidity of Ultrasint® PP nat 01 makes the material especially well-suited for technical applications and durable 3D printed polypropylene parts, from prototyping through to functional parts.

Excellent chemical stability, low water absorption
Good mechanical strength, rigidity, elongation
Optimized formula for laser sintering process

Min Supported Wall Thickness A supported wall is one connected to other walls on two or more sides.	0.5 mm
Min Unsupported Wall Thickness An unsupported wall is one connected to other walls on less than two sides.	0.6 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.	0.5 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.	0.6 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.	0.6 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.	0.5 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.	0.5 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.	0.8 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.	No

Material Spec Sheet

SLS Polypropylene (PP) 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.
