    More Details

    taulman3D and Graphene 3D Lab Inc. have teamed up to bring Nylon 680 to the 3D Printing community!

    Nylon 680 is at a minimum an FDA CAS Reg. No. 51995-62-1 6/69 Nylon developed and tested to meet 21CFR177.1500 / 21CFR177.1395 3D Printer Filament

    General Information:
    The first unique property of Nylon 680 is it's specific development for FFF 3D Printing.  Commodity FDA nylons are prone to a phenomena known as "clumping" or inconsistent viscosity during the 3D Printing extrusion process.  This inconsistent viscosity will always leave 3D Printed parts with random gaps and in some cases loss of bonding contact to the previous layer.  Nylon 680 is specifically designed to completely eliminate this problem, making the 3D Printing process as seamless as printing many other polymers now in use.  The next major improvement comes in Nylon 680's ability to handle the high temperatures of boiling water, steam and dishwater usage.  While some nylons will deteriorate to the point of being unusable, parts made of Nylon 680 can stand insertion into boiling water and only need to be dried to return to use.

    For manufacturing or conversion from pellets to 3D Printing "line", another feature of Nylon 680 is that it is not extruded, but "drawn" and done so, under water.  The water in the draw process is maintained and continually refreshed to have a pH of ~7.0 - 7.2 and an ORP greater than 600mv.  From the draw process, the material is down spooled by machine and delivered to the taulman3D facility where each spool is checked, labelled and vacuum sealed.  Spools are labelled on both sides and contain 2 QR codes.  One code for printing information and the other denotes the manufacturing batch code/date of mfg.
     
    For quality control of 3D Printed parts, Nylon 680 is very transparent and allows for easy non-destructive evaluation on a light table.  One of the most important quality requirements for 3D Printed parts is the correct adhesion of the internal fill material to the inside wall of the inner most perimeter.  When a printer is operating too fast or it is running at a lower than "set" temperature, the fill will not properly adhere to the internal perimeter making for a part that may appear to be correct, but instead be defective. The only way to test for this is to do a destructive test, unless the material is transparent enough to allow for visual inspection on a light table.
    NOTE: The specifications below are the results of actual 3D Printed Tensile test bars that have been placed in boiling water "~100C" for 15 min. Then forced air dried for 12hr's at 15% humidity, sealed and sent to the test labs.  Parts "NOT" placed in boiling water will have a higher Tensile and lower Elongation.

    Nylon 680 Specifications:
    Tensile Strength = 4,686PSI +
    Modulus PSI =28,634
    Max Elongation at break = 226% 
    Print Temperature = 250C - 255C
    Nozzle size = Any 
    Print Bed = 
    Cold = BuildTak with coat of PVA
    Hot = Glass heated to 50C with coat of PVA
    (PVA is 20% water  and 80% "Elmers Glue All - or equivalent")
    Shrinkage = 0.006   in/in
    Transmission = ~70%
    Colour = Subtle translucent Shell White when printed solid - May be dyed with acid based dyes.
