taulman3D and Graphene 3D Lab have teamed up to bring Nylon 680 to the 3D Printing community. Last November, the two company signed a memorandum of understanding (MOU) to co-develop a graphene-enhanced nylon material for 3D printing. The agreement also grants Graphene 3D exclusive distribution rights for Taulman's Nylon 680, a novel high-strength 3D printing material, for a period of two years in the USA, Canada, and Mexico. Sales of Nylon 680 are expected to begin in the first quarter of 2015.

Today taulman3D announces the Nylon 680 is FDA approved for food and beverage contact. Unlike other polymer materials, the Nylon 680 is designed to handle the high temperatures of boiling water, steam and dishwater usage. One major feature of Nylon 680 is its consistent melt viscosity. "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." notes taulman3D.

Small Electronics Enclosures

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.

Another feature of the Nylon 680 is is its transparent properties. The material is very transparent and allows for easy non-destructive evaluation on a light table.

Nylon 680 Specifications: (Parts were placed in boiling water "~100C" for 15 min prior to being sent to the test lab. This gives the end user more realistic tensile and elongation specs. Parts "not" placed in boiling water will have a higher Tensile and lower Elongation.)

  • 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
  • Shrinkage = 0.006 in/in
  • Transmission = ~70%
  • Color = Subtle translucent Shell White when printed solid - May be dyed with acid based dyes.
  • Availability = 1.75mm and 2.85mm Material is on-hand and shipping worldwide now.

"At taulman3D, we have established an excellent technical relationship with Graphene 3D Lab Inc.." taulman3D says. "This relationship allowed us to bring this material to the 3D Printing community much sooner than originally planned. Our continued co-operation will allow us to perform even more testing on Nylon 680 to widen the capabilities."

The Nylon 680 is available for $70.00/1 lb spool.

I wanted to send a quick note regarding your website. I can make changes or do a total re-design so that your site will convert more visitors into revenue with a conversion optimized design. I would just need to know if you're open to checking out information about a website re-design. Would you be open to seeing more info and a quote for what I would like to accomplish? Thanks for your time Michael

Too expensive.

How does this work? The filament is food/beverage approved. How does this work with the print? If you first print with (for example) ABS - clean the nozzle and then start printing with this filament; the print can not be FDA Food Proof - can it? An 'home' 3d printer can not be food proof - can it?
