[New 3D Printing Product] Ultra-durable Ruby 3D Printing Printhead: 7 Features You Must Know!
Our large 3D printing community not only has in-depth knowledge of Ultimaker products, but is also happy to share expertise with all users, enabling 3D printers to achieve even more; one of the biggest contributors today, Anders Olsson, has developed the ultra-durable 3D printhead CC Red 0.6. 
What are the features of the CC Red 0.6 ultra-durable ruby printhead?
• Capable of using highly abrasive materials. • Has passed extensive 3D printing tests on carbon fiber. • Constructed with an ultra-wear-resistant ruby core. • 0.6mm diameter, balancing printing accuracy and speed. • Quick nozzle change, similar to Ultimaker nozzles. • Sufficient width to prevent clogging. • First available in mid-November this year.
Anderson Orson is the developer of the Ultimaker 2+ printhead, used for 3D printing with boron carbide. Now, Anderson has developed our Print Core CC Red 0.6 – an ultra-durable ruby nozzle for the Ultimaker S5 , which is still quick to change like other printheads.
Andersson is a research engineer at Uppsala University in Sweden, and his expertise in boron carbide composites in the 3D printing industry is well-known (boron carbide is one of the hardest materials in the world). 
Develop ultra-wear-resistant nozzles
Printing with this highly abrasive material requires nozzles that are more durable than brass. Brass nozzles are damaged and leave residue when printed with boron carbide. Besides affecting nozzle accuracy due to wear, the high-strength composite material itself can also corrode other nozzle joints; both types of wear affect print quality.
The initial inspiration came from the need for 3D printing with high-content boron carbide composites, a material that offers superior performance compared to standard boron carbide but is considerably more expensive. The Ultimaker S5 3D printer utilizes dual printheads, allowing for the simultaneous printing of both standard and concentrated boron carbide composites in the same print job, thus ensuring that the expensive material is used only where truly needed. Maintaining both printhead stability and enhanced abrasion resistance is the primary reason for choosing ruby as the core material.
Why choose rubies?
Ruby is extremely hard, chemically stable, and non-toxic. Even if it is accidentally scratched, there is no danger (for example, the cobalt binder in tungsten carbide will cause problems in the neutron state). Ruby can provide full functionality for 3D printing on any abrasive wire. In addition to abrasive materials, Anderson has also tested non-abrasive general wires and found almost no defects. 
Santima will also begin selling the Ultimaker CC Red 0.6 Ruby Printer in mid-November this year.
With a diameter of 0.6 mm, it achieves the best balance between speed and accuracy in 3D printing ; in addition, the diameter is wide enough to prevent clogging, as abrasive materials containing fibers may cause material blockage when using smaller nozzles.
The testing team also cut open a nozzle and printed approximately 25 kilograms of carbon fiber, which remained intact without any wear. When printing with ordinary carbon fiber filament, brass nozzles can typically withstand 300 grams of printing, stainless steel nozzles can withstand 1 kilogram, and hardened steel nozzles can withstand 3 to 5 kilograms. However, ruby is wear-resistant but relatively hard and brittle, so it should be protected from drops or impacts. Care should be taken when cleaning, and the nozzle should never be exposed to flame, as this could deform the surrounding brass and damage the ruby core.
What causes materials to become "abrasive"? 
Generally, all composite filaments (e.g., metals, ceramics, carbon fibers, etc.) exhibit abrasiveness unless the composite material's hardness is significantly lower than that of standard brass (e.g., wood). However, some abrasiveness is less noticeable; for example, some fluorescent or glossy materials contain ceramic powder to produce luminescence, which can also cause abrasiveness in the filament. (The right side of the image shows the wear of the brass nozzle in 3D printing .)
Anderson continues to test special materials that are radiation resistant, magnetic, conductive, or can be fired into ceramic objects after printing, and continues to work to combine multiple properties. The use of these composite filaments will be achieved through dual-printer 3D printers such as the Ultimaker S5 , and with the ultra-durable ruby 3D printing core CC Red 0.6, to achieve the best results for each printed element.
