January 10th: Updated with images of the finished part

This is a print we have made before and one that is an excellent example of how well overhangs are handled with PA-CF Low Warp, our new nylon based carbon re-inforced engineering filament. The Garden Sprinkler by Daniel Norée is a great design to showcase our filament with.

We scaled the sprinkler to 200% scale to show the awesome ability to print overhangs. Not only does this high-end filament print very well on a wide range of printers (find out how to print), but it shows excellent properties like strength, low warp and also overhangs. Only this morning we featured the ability to have great looking prints and with the ability to print challenging overhangs we know we have released a filament that is perfectly suitable for the professional user who needs a high quality filament that performs!

The formulation has been modified to reduce the uptake of moisture by half compared to PA6 and it also takes about 4 times longer to reach the saturation point. This makes PA-CF Low Warp less sensitive to moisture then most other nylon filaments available in the market. You can find more information about the printability of PA-CF Low Warp on our dedicated landing page.

We printed similar to previous posts on the Ultimaker 2+ using an Olsson Ruby nozzle. Print settings used were 260C hot end temperature with a 50 degrees C bed temp and at 0.3mm layer height.  Fan cooling is set to 70% and used 80% of the original speed, this gives plenty of time for cooling and results in very crisp overhang geometries.

Daniel Norée is well known for his Open RC project (where we printed a large version of his F1 design), but he has more than 120 designs on Thingiverse – under his handle barspin – very functional and cool ones among them.

The PA-CF Low Warp is a one of a kind polyamide formulation with the ability to print nearly warp free on non heated buildplatforms. Low infill prints come out perfectly flat on cold bed for higher infill prints 40/50C temperature is enough to obtain flat prints. This tailormade formulation of polyamide features the mechanical properties of a PA6. Tensile strength was measured at 77,99 MPa and impact strength (notched) was measured at 5,44KJ/m2, test specimens both printed on Ultimaker 2+, 260C 0.1mm layerheight with 100% infill.

The finished part looks amazing!

PA-CF Low Warp is available now in our webshop and ships from stock.

The Olsson Ruby Nozzle – One nozzle for all materials

Due to the abrassive nature of the filament we recommend the use of hardened nozzles for the best performance of the material and printer. For this reason we are offering the Olsson Ruby Nozzles with the purchase of PA-CF Low Warp. You can find the combined offer here.

We have published about the use of the Olsson Ruby Nozzle before and we are very enthusiastic about the use of this filament combined with abrassive materials like PA-CF Low Warp, but also XT-CF20 and steelFill.

The ruby mounted at the tip assures that even the toughest materials will be printable. It was originally designed for printing with a composite of Boron Carbide (B4C), the third hardest known material in the world. Since most of the Olsson Ruby is made from brass, with its excellent heat conductivity, performance and throughput is first-class.

This nozzle, soon on your printer!

The Olsson Ruby is manufactured, assembled and tested in a high-quality facility in Sweden. This is why 3DVerkstan – also colorFabb’s partner in the region – guarantees the very best quality and tolerances.

As from now you can purchase the Olsson Ruby Nozzle 0.4mm in combination with PA-CF Low Warp in our webshop.
