Received, and thank you very much.

Two 'discoveries' to pass on:

- Once the first spools are half used the nylon spins in the shell freely, which means that I can hang the shell stationary (on the corner that sticks out) and the filament comes out of the one section that's open (to the left of the corner).
- The new spool's "lips" are a bit looser than the first shell. I guess it's random manufacturing variation, but the filament feeds out of the new spool more easily than the first one.
- Both spools rotate better horizontally than vertically. I put them on a broom handle, next to the printer and sticking vertically, rotating on a round plastic washer.
I've been printing Nylon for days, so plenty of motivation to test new spools. Thanks!
Thank you, Sir! As you might imagine, it's extremely busy here as any help you can provide to us all is greatly appreciated. If you don't mind, I'm going to send three spools so you can experiment to the fullest. Therefore, please don't hesitate to try as many solutions as you have time for. Again, thank you for your time and help.

Instructions

Print 2 each with general settings.
Slot plastic shell for center rod and wire tie to hold the two sections.

With the pliability of Nylon we are designing a newer spool and a couple new packaging forms for reduced overseas shipping costs.

So how does this function as a 'hub'? The coil of filament comes in a plastic shell that doesn't have a hole in the middle, so it can't function as a "spool" that I can see. This shape looks like it might fit onto the two plastic bumps in the shell, but the bumps are conical, so this wouldn't snap onto them, and there's no hole in the middle, so I don't see how this would work as a 'hub'. What am I missing?
laird - in reply to laird
After some testing, the answer to "how does this function as a hub" is "extremely badly". The problem isn't really this "hub" - the real problem is that the filament isn't tightly would onto a spool, it's loosely looped into the plastic shell. This means that when the printer pulls the filament out, the spool doesn't rotate. Instead the filament pulls from one spot (stuck in one spot by the "lips" on the shell) with the filament inside the shell pulling tighter until it can't be pulled any more.

While the plastic shell that it ships in looks clever, it's not functional as a hub. Perhaps it's more boring, but perhaps Taulman should buy some standard spools and ship the filament on them. Or at least tell people to carefully wind the filament onto a spool before using it.

Don't take this as a negative of the filament - it's great stuff.
First, thank you, laird, for your comments on 618.

As 1.75mm 618 was released less than a month ago, we are like you, seeing the line spin on occasion within the shell. I can assure you that the 1.75mm spool is a priority for us, just as any other technical aspects of 618. As mentioned, it is extremely important that as many users have successful prints as possible. Specifically, we are looking at the best spool that accommodates usage and lower shipping costs as shipping, of course, plays a large part in access to 618 for users all over the world.

Again, thank you for your comments on 618.
Thanks for such a quick response! I am really enjoying experimenting with your filament.

Some comments on the 'shell':
- The leading end of the filament is nicely secured on the outside of the shell, but the trailing end doesn't appear to be secured. Given how amazingly slick Nylon is, this means that the filament ends up loose in the shell, not tightly wound, so pulling on the filament just causes it to pull tight instead of rotate the shell. At least for my first 'spool', the filament doesn't spin in the package - it pulls tight and then gets stuck, causing prints to fail.
- The curved lip on the shell looks cool, but it (at least for me) causes the filament to feed out of one spot instead of winding around. It's possible that if the shell lip were straight it might unwind better.
- The triangular part sticking out (where it hangs, and where the filament was secured) catches on things, so it doesn't rotate smoothly.
- And, of course, there's no hole in the middle. I cut one, but it's fairly uneven which didn't help matters.

So, to turn the above into suggestions:
- Secure the 'tail' of the filament somehow, and make sure that the filament is spooled tightly before the leading end of the filament is secured.
- Consider making the 'lip' straight.
- Punch a hole in the middle of the shell. You could still have the paper label cover the hole, so you have room for labeling, etc.

Or tell people that they need to re-spool the filament. The shell keeps things neatly in place so it's not too hard to re-spool, and from a standard spool it prints fine.
Again, thank you for your comments on 618. Just a quick question. While I have both a designer and my extrusion house looking for an alternate, it will be a few months before I can begin with a newer spool. If I were to ship you (at my cost) two spools to experiment with, would you have the time to try different techniques, givin it's current design, as you mention above and report back..? Thank you, in advance.
I would be happy to try them out. I am laird at popk dot in.

Cool. Godspeed in your future endeavors!

I added your page to: reprap.org/wiki/Printing_Material_Suppliers

It will be a very interesting development to see this  and other kinds of filament being pushed to the addicts. Especially as its real easy to hold a specific temperature these days.
 Thank you, for adding our Nylon Materials to the wiki!
With the elimination of delamination, pliability in smaller parts and strength in the larger parts, we're anxious to see what new ideas/designs will become part of Thingiverse and beyond.
Say, would you mind making some sort of shipping cost page for the most common destinations? I'm thinking UK, Norway, Spain, domestic...

Also, I would be really interested to hear what you as a supplier of filament think about the customer-review initiative I made on the previous mentioned & linked page.

It would be totally awesome if you could mention or even encourage your customers to review their filament at the RepRap wiki and thereby show that your customers endorse your products and you get Free advertisement in both senses!

Btw, if you do the latter, I´m going to work way more on Aliphatic polyamides-matters on the wiki. Free documentation.
Great suggestion on the shipping costs. I'll add a easy to select list asap.
Being listed at reprap.org is a definate plus.  I know everyone here uses it as "the" reference.  I've added this to my site, but will need to go a bit further so users can find the start link to all available vendors/materials.
The tester feedback on part strength has been excellent. So I'll pull together some additional spec info.
