taulman, creator of 2BEIGH3, a CNC machine and high temperature 3D printer all-in-one, announced today the taulman 618 Nylon material is available for sale and first orders will begin shipping Nov 12th. This taulman's "618" high strength nylon line is specifically engineered for 3D printing.

Specifications:

  • Size = 3mm Diameter +/- .1mm
  • Color = Natural - Prints as a base pure white with a translucent surface. Add color with most acid based dyes.
  • Temperature = 235C to 280C - Part/Speed dependent. 240C-250C is best for most parts at average printing speeds.
  • Co-Polymer = 4-Station-Drawn and Extruded "3D Printing Specific" Nylon based co-polymer. Specifically designed for 3D Printing applications where excellent surface bonding, reduced water absorption, tear resistance and dye absorption are combined in an easy-to-print 3mm line.
  • With a visual and tactile surface quality 2nd to none. Parts 3D Printed with taulman 618 Nylon will be instantly recognizable as Nylon rather than any other plastic.
  • Chemically resistance to = Alcohols, Resins+MEK, Oils, Acetone, Most all Alkaline, most 2 part Casting Compounds.

taulman 618 Nylon comes in 1 pound rolls (approximately 180 feet or 54 meters) , packaged in an edge delivery spool (9" dia x 1.75" thk) (228mm x 44mm thk) for convenient mount and print. As promised to early material testers taulman keeps the sale price very close to ABS filament: the taulman 618 3D printing nylon polymer comes with a price tag of $19.75 per 1 pound spool (3mm round natural).

Like any new material, taulman 618 has been tested numerous times before it is finally approved. Below is a photo taulman took of a large table with most of the 1,000's of parts and the 17 different copolymers they tested before he finally approved 618. Every polymer and copolymer on that table was rejected.

"Getting a nylon copolymer to 3D print correctly, maintain it's strength, maximize the layer to layer adhesion, reduce the hygroscopic effects and still maintain nylon's noted natural luster was the goal. And I believe that with 618, we've met that goal. One of our local testers that burnt out a few stepper motors helping us say's "If you're not printing with taulman 618, then you're probably printing with one of his rejects". Early feedback from external testers is very pleasing, but we're wanting more people to try the material and see for themselves." says Taulman.

"There has been excellent support from those in the 3D Printing community. From our 618 material testers, to small CNC machine shops, there have been hundreds of tests and more great application ideas than I've had time to explore."

"The benefits of 3D printing with 618 open up whole new areas of both design and actual part usage. Not only do those in the current 3D Printing community see new possibilities, but there has been a few small CNC shops that either have a 3D Printer or are building something compatible with their existing CNC hardware. Early on, we had some requests to "test print" parts for CNC shops so they could determine if a part printed in 618 would actually work in small moving assemblies. And today, there is at least one shop that plans to print small production orders with 618."

Here are a few ways 618 is helping these CNC shops:

1. Holes for threaded rods, screws and bolts. - They 3Dprint a small to med sized part with round holes slightly smaller than required. They then simply use a "TAP" and tap threads into the holes. 618 doesn't crack or delaminate like their ABS parts, so threaded parts are a snap.

2. Compression flanges. - In some assemblies, to protect from dirt, special thin gaskets are used with exact sized spacers or flanges. They can now 3D Print an slightly oversized flange and the compression capability of the nylon forms a seal with just the one part.

3. Gaskets - In the past, most gaskets are die cut. Now, they can either directly print nylon gaskets or print unusual gasket patterns and do a real time test with 618.

4. Mold Making - Even simple sign molds are sometimes made of aluminium due to the use of harsh industrial molding and casting compounds. These shops can now simply print molds in 618 and because of it's smooth nylon surface, pliability and resistance to most chemicals, molded parts are available as soon as the compound sets. Below are some photos of simple molds and the results (click to enlarge). You can also see just how pliable 618 is. You'll also see just how permanent a 3D Printed right angle joint can be with 618. The chemical resistance to several solvents and 2 part casting chemicals is another benefit of 618.

taulman's goal is to have the strongest 3D Printing materials available. His team has already submitted a new copolymer for samples. "While this new copolymer will be nylon based, it will use a different mfg method and will provide even stronger material properties, a lower print temperature and slightly less pliability for stronger small parts and larger parts that hopefully rival aluminium for some applications." added taulman.

Do you know the material properties for this nylon filament? I am looking for something with a high sheer strength.
