• 1.75mm Nylon Filament - Taulman 645

New, from the manufacturer of Taulman 618 Nylon 3D printer filament, in our assortment is Taulman 645 Nylon 3D printer filament. Taulman 645 has remarkable characteristics when it comes to strength (St: 16,533 psi /114MPa), surface bonding, and durability (exp. elongation at break = 120%).

Taulman 645 Nylon is a 3D printer filament which is specially designed for 3D Printing purposes where excellent surface bonding, reduced water-absorption, tear-resistance and transparency are joined into a 1.75mm and 3mm 3D printer filament.

Printing Taulman 645 Nylon Filament is similar to printing with Taulman 618 Nylon filament. The recommended printing temperature for Taulman 645 is ~230°C to 265°C. Taulman 645 Nylon has comparable warping properties as Taulman 618, but with an improvement in strength, surface bonding- and clearness properties.

We currently sell Taulman 645 Nylon filament in spools of 450 grams.

Features of Taulman 645 filament

  • Taulman 645 Nylon is Manufactured in the U.S.A.;
  • Very High Strength - Expected Tensile Strength, Yield = 16,533 psi (114MPa);
  • Extreme Durability - Expected Elongation at Break =120 %;
  • Excellent Bridging performance;
  • Superior Surface Texture;
  • Taulman 645 Nylon Co-Polymer consists of the purest form of a delta transition of Nylon 6/9, Nylon 6 and Nylon 6T with a crystallinity optimization process in addition to post processing for maximum bonding during a thermal transition (3D Printing);
  • Taulman 645 meets the EU's "REACH" requirements as defined by the ECHA European Chemicals Agency. There are NO additives or chemicals in Taulman 645 that are listed in the REACH Directive.

Tips and Tricks for using Taulman 645 Nylon filament

  • Taulman 645 has a slightly higher viscosity than other printing materials.  As the layer height exceeds 50% of the nozzle dia, printing speed should be adjusted downward ~10% - 20%;
  • Retraction: due to a slightly higher viscosity, the retraction distance may need to be lengthened;
  • Excessive bubbles in the printed thread are an indication of a higher than required print temperature. Reducing Print temperature below 238C will result in less thread opacity due to recombination with the atmosphere, however this will also reduce bonding in layers exceeding 25% of nozzle diameter;
  • Shrinkage is equal to ABS and can be controlled using garolite (LE) as a print table cover/plate;
  • Heated beds help just as they do for printing with ABS;
  • Note: currently Taulman 645 measures 1.76mm to 1.83mm dia in a slightly oval shape due to the draw and cooling process. The line cross section is constant, however users should make a slight adjustment to their "Material Diameter" (1.78mm - 1.80mm) settings to accommodate this slight variance.

Everyone with a 3D printer is familiar with PLA and ABS.

If you’ve printed with PLA, you probably know that while it’s fairly strong, it’s also very brittle. You can’t leave parts out in the sun or anywhere that the temperature gets above 100F.
If you’ve printed with ABS, you know it’s much more durable than PLA, but 3D printed ABS parts don’t have the strength of injection molded parts, and often aren’t strong enough for functional parts.

Enter Nylon.

Nylon is an incredibly strong, durable, and versatile 3D printing material. Flexible when thin, but with very high inter-layer adhesion, nylon lends itself well to things like living hinges and other functional parts. Its low friction coefficient and high melting temperature make it an excellent choice for things like printed gears.

Here’s what you need to know to start printing with nylon:

1)      Not all hot ends are created equal. 
Nylon requires temperatures above 240C to extrude. Most printers come standard with hot ends that use PEEK and PTFE. Both PEEK and PTFE begin to breakdown above 240C and will burn and emit noxious fumes. If you aren’t sure if your hot end can print with nylon, send us an email or check with your printer manufacturer. Most printers can easily be upgraded with an all-metal hot end in order to print at temperatures above 240C. We use the E3D all metal hot end on our machines. They’re excellent hot ends and we highly recommend them. You can purchase an E3D hot end here.

2)      Nylon must be dried.
Nylon is very hygroscopic. That means it readily absorbs water from the air. Nylon can absorb more than 10% of its weight in water in less than 24 hours. Successful printing with nylon requires dry filament. When you print with nylon that isn’t dry, the water in the filament explodes causing air bubbles during printing that prevents good layer adhesion and greatly weakens the part. It also ruins the surface finish.
Dry nylon prints buttery smooth and has a glossy finish.
To dry nylon, place it in an oven at 180-200F for 6-8 hours. After drying, store in an airtight container, preferably with desiccant.

3)      Nylon can warp.
We’ve found it to warp about as much as ABS.
When printing on glass, a heated bed is required with nylon. A PVA based glue stick applied to the bed is the best method of bed adhesion. Elmer’s or Scotch permanent glue sticks are inexpensive and easily found.
We’ve found that a bed heated to 75C, with thin layer of glue applied in a cross-hatch pattern works best.
Do not use layer cooling fans.
Avoid drafty or cool rooms for best results.

Recommend print settings:

240-260C Extrusion Temperature (each type of filament is slightly different. Follow manufacturer's recommendations)
70-80C Bed Temperature with PVA based glue
Speed: 30-60mm/s
.20mm-.4mm layer heights
