Taulman3D Releases Nylon 680 3D Printer Filament – FDA Permitted for Meals Contact & Extra – 3DPrint.com
When it comes to the materials science behind 3D printer filaments, few, if any, companies have the experience that taulman3D has. You released some of the most versatile filaments we have have seen so far specializing in a wide variety of nylon materials.
As early as November we announced that taulman3d was working with another very interesting company in the field of 3D printing materials, Graphene 3D Lab. As part of this partnership, the companies announced that Graphene 3D Lab will have exclusive distribution rights to an upcoming nylon material that taulman3D is expected to release in the first quarter of 2015. Just one more day in the quarter, it seems today is that day.
This polymer is called nylon 680 and is unlike anything you’ve seen in the past. It has been in development for over 8 months and is FDA cleared for uses that require food or beverage contact. This is due to its ability to handle high temperatures associated with steam, boiling water, and the use of dishwashers. It was specially developed for FFF 3D printing and, like all filaments from taulman3D, has a constant melt viscosity.
Unlike many of the filaments we are discussing, which require the pellets to be converted into strands and spools of filament, this new nylon 680 filament is not extruded but rather drawn under constantly updated water that has a pH of 7.0 to 7 , 2 maintains.
Below are the full specifications of this new filament. It is important to note that these results are based on tests performed on 3D printed tensile bars that were first boiled in water at ~ 100 ° C for 15 minutes and then placed in a dry room at 15% humidity for 12 hours.
- Color: Subtly translucent Shell White when printed firmly – Can be colored with acid based dyes.
- Availability: 1.75mm and 2.85mm of material are available and are now shipping worldwide.
- Tensile Strength: 4,686 PSI +
- PSI module: 28,634
- Required cold pressure bed: BuildTak with PVA cover
- Required hot pressure bed: Glass with PVA coating heated to 50 ° C
- Maximum elongation at break: 226%.
- Printing temperature: 250 ° C – 255 ° C.
- Shrinkage: 0.006 inch / inch
- Transmission: ~ 70%
Another advantage of nylon 680 is its translucent and somewhat transparent properties. In this way, printed parts can be visually checked for defects such as defective internal filler adhesion. 
without the need for destructive testing.
Taulman3D said the partnership with the publicly traded Graphene 3D Lab should help advance materials research and further expand the possibilities of this nylon 680 offering. For those interested in this new filament, it’s available for $ 70.00 / 1 lb spool. Let us know if you had the opportunity to use it and what your thoughts were. Discuss on the Nylon 680 forum thread on 3DPB.com.
