Boron Carbide Filament?

With apologies if I am way behind the times.

 

Reading the great article on the origin of the ruby tip, I found the choice of material interesting.  Is this filament in use outside of the research sphere?  What is it best for?

 

Thanks in advance.

    The only reason for us to use boron carbide is that we want to absorb neutrons and boron (the 10 isotope) has very good properties for this.

     

    Boron Carbide is a chemically stable reasonably priced ceramic powder with high boron content (four boron atoms and one carbon atom).

    While a softer material with high boron content would have been preferable, there are no such options in a reasonable price range.

     

    Other uses is for example as a grinding powder, which explains why it eats 3D printer nozzles ?

     

    That is the basic reason behind the Olsson block and the Olsson Ruby nozzle, summed up in a few sentences ?

     

    If you are interested in further reading, we have published much of our work in an open access article: http://iopscience.iop.org/article/10.1088/1402-4896/aa694e

    (Check out the Supplementary Data too for information about the Olsson block and other stuff)

     

    There is currently no commercial production of boron carbide filament but there might be in the future.

    Be ware though, if you even come across it, that boron carbide is one of few materials which is harder than ruby, so it will slowly wear the ruby.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
