Recently we announced the winners of our Design Challenge. The idea was to send us functional designs that we would print with PA-CF Low Warp, our engineering grade and nylon based filament. 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. PA-CF Low Warp excels in tensile and impact strength and allows continues use at 120°C while retaining sufficient mechanical properties.

A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. ColorFabb recommends to using wear resistant nozzles, such as the Olsson Ruby nozzle.

Last week, Swedish 3D specialist 3DVerkstan – our distributor in the Nordic countries contacted us. They were more than happy to provide the five winners of the challenge with an Olsson Ruby Nozzle, which would be added to the the 2 spools of PA-CF Low Warp they were already getting.

A fantastic gift and a very useful one as well. The winners, who were contacted about this, were very grateful and they can expect the nozzles with them soon. Thank you, 3DVerkstkan for providing these nozzles!

In a world where 3D printing users require more functional and exotic filaments, we try to keep up with the demands. Although we aim to make sure our filaments work on as many printers as possible, we know that not all materials are a good fit for every printer. Abrasive materials like PA-CF Low Warp, XT-CF20, steelFill and to a lesser extent glowFill wear out the standard brass nozzles too fast.

In the words of Daniel Ljungstig, CEO of 3DVerkstan: “The Olsson Ruby is a high-tech nozzle with a carefully designed ruby tip, which makes it have unique properties. The ruby nozzle is designed by Anders Olsson, inventor of the popular Olsson Block that is also part of the Ultimaker 2+ 3D Printers. He designed it to be able to print extremely hard materials for scientific research at Uppsala University in Sweden.”

We have seen quite some benefits over the regular brass nozzles that are the current industry standard: The ruby nozzle retains the excellent heat conducting properties of brass, while being extremely resistant to wear. This means that you can print your standard materials as usual, but also very abrasive materials such as PA-CF Low Warp, XT-CF20 and steelFill. Daniel Ljungstig adds: “In addition to this, many of our test users have reported an improved surface quality compared to standard nozzles.”

It is a well established fact by now that our new PA-CF Low Warp filament is all about functionality. We developed this filament with only one goal: to make sure a lot of users have the ability to print high quality printed parts. Even on a cold bed. PA-CF Low Warp is, due to its stiffness and strength, a perfect material for replacement parts and custom made parts.

The PA-CF Low Warp filament 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.

PA-CF Low Warp allows continuous use at 120°C while retaining sufficient properties for the intended application. Most high heat resistant materials will be difficult to print and require heated chambers and / or heated platforms to keep parts from warping the bottom layer. PA-CF Low Warp shows a very low tendency to warp, even at ambient temperature platform.

PA-CF Low Warp is available now in our webshop and ships from stock. We currently stock spools of 700 grams, but as from late next week large spools containing 2kg of material will be available as well.

You can also opt to get a unique bundle package, containing one spool of PA-CF Low Warp and the Olsson Ruby Nozzle 0.4mm in our webshop.
