Taulman 645 Nylon

Post by JuliaDee » Wed Apr 17, 2013 8:48 pm

Got a spool of Taulman's latest brew today, "645" - crazy-strong stuff. As shown on the website, you can whack these parts with an 8-pound sledge and they don't break.

http://www.taulman3d.com/645-features.html

The website recommends a 1:1 bead (0.4mm layer height with a 0.4mm nozzle diameter) but honestly I think the parts are just as strong if not stronger with a 0.2mm layer height, and of course appearance and detail are way better.

I printed using the same settings I've been using for 618: lowered temp, fan duct closed, garolite plate, fast print speed. No issues printing with the 645 at all, and support was not particularly hard to remove.

How is it comparing to 618? The difference?

Oh wow, more awesome printing material - life is good! I can't wait to get my hands on some of this.

The printing experience has been virtually identical so far, albeit with a small number of small parts. But it does raise the question of why, if 645 is stronger than 618 and there's no downside, would I ever print with 618? I think I'll have to put that question to Taulman...

It's difficult to photograph this stuff due to its transparency (it's more "crystalline", as opposed to 618's "milkiness"). In the first photo, the 400u layer thickness part is on the left, and the 200u part on the right.

If its nylon, can someone try boiling a part in dye to see if it readily takes colour.

Yes, Taulman nylon is easily dyeable with RIT or other clothing dyes; there are many internet references for dyeing either finished parts or raw filament, including this particularly interesting one involving partial dyeing of filament for multi-colored effects:

Do keep in mind the boiling/dyeing process may change the properties of your nylon to some extent. Where used to do it to RC gears to get longer wearing gears - it made them a letter less brittle. Keep in mind this was typically boiling for about 20mins and you can get good colour with just a few short dips especially if you use dyes at fairly high concentration.

Cheers Roller,
YES, it was from the days I used to boil nylon propellers in dye for control line models. Boy, time has flown faster than any of my models :D

Wow, there's a blast from the past. Does anyone still fly control lines I wonder... I've not seen one for ages!

Nah..... Laystraight wire and a control line handle are more expensive than a radio set :shock:

Any further comment on choosing 645 over 618? I heard that the 645 is still under the testing stage.

No, I've been wrapped up in other stuff with no time to experiment further with the nylon.

The $10 price difference would be a good place to start.

Maybe a difference in stiffness/flexibility?

There is a reasonable price difference between the 2 products, so if you don't need the extra strength or the transparency then 618 might be the better option.

Hi all
I really like the 618 supplied to me by Jamie (wilsonj). It bonds well and when printing at 0.15mm layers, the layers tend to "crystalise" together to make a very strong bond. And even more so at 0.1mm layers. I will be receiving a digital microscope soon - when it arrives I hope to be able to post some great photos of layering. I think I might have to also get some 645 nylon as well to make very strong nuts and bolts.
This week I went to an Expo held in Melbourne. While there I had a chat with Bruce (wackojacko), and he showed me a notched drive belt printed on an Up! using the flexible rubber-like filament.http://3dprinterfilaments.com/rubber_%20like_filaments
It was amazing. The belt was incredibly flexible but could not be stretched. It looked to be very useable as a drive belt.
3D printing is rapidly moving in leaps and bounds. ABS, PLA, PVA, nylon, polycarbonate, rubber-like, and even wood-like filaments. What's next? We definitely live in exciting times.
Regards
Lawrence

If I use 618 or 645 to replace thin aluminum brackets (thickness 1.5-2mm), will they break easily? Is it better not to use the stock nozzle if I end up printing using these materials?

Nylon won't break very easily, it will bend though, and this could be an issue at 1.5-2mm. No problems using the stock nozzle on the UP either. Just do 3 or 4 purges when changing to a new filament afterwards as it tends to "linger" in the hot end more so than ABS or PLA.
