    I just learned last night that Taulman has released a new Nylon and is calling it Bridge. As in it is a bridge between properties of ABS and 618.

    The stated benefits of this material are that it has close to the same strength, flexibility, and temperature resistance as 618, but is easier to use. It can be printed on a PVA (glue) coated bed, has less tendency to warp, and only absorbs minimal moisture. No bakeout should be required prior to printing.

    The other pro is that cost is a little lower. Should be just under $20 for a 1 lb spool.

    I have some on order and will post results. Anyone else want to get in on the early adopter group?

    I'm pretty excited about it. Nylon is such an awesome printing material, but it is so tricky.

    Wow at that price it is hard to pass up. I will look forward to your results and thoughts on it Matt.

    I should be getting a few spools of "Bridge" filament sometime tomorrow. I got the impression that "Bridge" has the strength of 645 nylon:

    Either way still looking forward to seeing the improvements of printing vs nylon 618.

    I've only had a chance to print one part because I have a bunch of parts in queue that are other materials. Granted, this isn't a particularly tricky one, but it stuck quite well to glue stick on kapton with no observable warpage at the base. This was printed on a raft and the raft peeled off easily. 2014-03-23 10.52.28.jpg
    It feels about as strong as the other nylons. Specifically that wicked stress concentration at the base flange doesn't seem to budge when I push on it pretty hard.

    Looks nice, Matt! I hope my experience matches yours... Now you need a teeny Archimedan marble to watch go around...

    Went ahead and ordered some, you sold me :)
    (and I have been wanting to experiment with the nylon anyway)

    Same settings as 645. A 'true' 245 is best with slow settings below ~50mm/s or so. I ran my first print at 250. I did heat the bed to 70-90 from what I had read elsewhere, but I don't know how necessary that is.

    OK. Tried it and, well, wow. My 8 y.o. son ran out of glue sticks, so I printed with a raft on clean blue tape. 245 degrees at 30mms with an initial bed temp of 75 and I got a small amount of warpage, but not enough to either damage or ruin the print. It came out great. Strong, a little flexible and perfect for my use of this part. The raft was quite firmly attached. The pics show the finished top and shape and the warpage. It appears to be worse than it is in fact. I really like this stuff! 20140326_111807.jpg View attachment 2509

    Awesomeness! You should find that once you get that glue, your adhesion will be perfect and there will be little to no warping.

    I've been printing stuff for customers, so I can't share the pics, but I am really liking this material as well. Hopefully will do some of my own this weekend to share.

    I used 245 and 50 for the bed, it warped a bit on the first 1/2 dozen layers.
    I am going to retry with 90 deg. for the bed.

    I love how flexible this stuff is. Really cool.

    Use brim (6-10) layers and that will help too. Higher bed temps may not work well due to the differential between ambient and bed temps, but certainly worth a try. It is amazingly strong, don't you think? Glue stick is excellent, too. No tape or hair spray... Show us a pic!

    I'm trying to print this now. It seems like it has extrusion issues at higher speeds. I'm going to try tuning down to 30mm/s and see if that can get me to extrude properly.

    I did not have any speed related issues, but the temperature had to be at least 245 or it extruded slowly (which would probably have the same effect)..

    Are you using the Bowden, Mike?
