I found some nice Nylon I want to use but the largest filament size is 1.2mm and I am wondering how low can we go with the stuff that is out there? What would I need to change to go smaller? I have seem filaments go down below .5mm which is what I would use if I were using a .1mm head but I digress. Any ideas and frankly 1.2mm Nylon I can get a five pound spool ~1645 meters for 52 US dollars which is not bad ($12.50 for 330 meters). I can't find any in colors but printing with Nylon is pretty cool though the head has to heat up to 320c to extrude it. https://reprap.org/forum/read.php?1,143960,143960#msg-143960 Sun, 13 Sep 2026 04:30:05 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,143960,144318#msg-144318 https://reprap.org/forum/read.php?1,143960,144318#msg-144318
The only thing that annoys me is the warping of the print and the oozing of the nozzle. I get some blobs here and there because of the ooze. I am going to try to fix the warping using some perfboard or something. I am trying to get a nozzle with a longer orifice to reduce the ooze.

As for the strength of the part, I would say it is twice as strong as my ABS prints, and more flexible too. The layer adhesion is very good if you print it at the right temperature. 230 C seems to work very well, but I would like to go up to 240 C if not for the ooze.]]> galaxyman7 General Mon, 23 Jul 2012 20:23:26 -0400 https://reprap.org/forum/read.php?1,143960,144315#msg-144315 https://reprap.org/forum/read.php?1,143960,144315#msg-144315 -------------------------------------------------------

What is the finished quality and strength and does it have that nice oily Nylon texture?]]> Dark Alchemist General Mon, 23 Jul 2012 20:01:06 -0400 https://reprap.org/forum/read.php?1,143960,144310#msg-144310 https://reprap.org/forum/read.php?1,143960,144310#msg-144310 galaxyman7 General Mon, 23 Jul 2012 19:32:18 -0400 https://reprap.org/forum/read.php?1,143960,144140#msg-144140 https://reprap.org/forum/read.php?1,143960,144140#msg-144140 -------------------------------------------------------

Red color, round shaped line made from sturdy nylon components which does not mean 100% pure nylon as the weed whacker line I have used has other stuff in it as well otherwise I would be eating my line left and right (more so than I already do).]]> Dark Alchemist General Mon, 23 Jul 2012 02:57:35 -0400 https://reprap.org/forum/read.php?1,143960,144139#msg-144139 https://reprap.org/forum/read.php?1,143960,144139#msg-144139 -------------------------------------------------------

Smaller stuff (1.2mm vs your 2.667mm weed whacker line) at [www.amazon.com] more expensive, in clear, and being smaller may have some advantages.]]> Dark Alchemist General Mon, 23 Jul 2012 00:41:23 -0400 https://reprap.org/forum/read.php?1,143960,144111#msg-144111 https://reprap.org/forum/read.php?1,143960,144111#msg-144111
One tip though, you will want to get a nozzle with a longer orifice than normal. Nylon is much less viscous than ABS or PLA, so it oozes with a normal nozzle.

Also, you will need to dry it before printing, or else you will get a bunch of steam bubbling in your filament. Stick it in a toaster oven for a couple hours at 100 C and it will be dry enough. Store it in a ziploc when not using it.

Woohoo, that is exactly like the one I have from eons ago and about the same price with current currency exchange rates. I want another myself so I will look deeper but for one in the states.

Over here the best I can find would be 4 pounds 46p so slightly more but, then again, no VAT so I guess about the same.]]> Dark Alchemist General Sun, 22 Jul 2012 06:16:13 -0400 https://reprap.org/forum/read.php?1,143960,144002#msg-144002 https://reprap.org/forum/read.php?1,143960,144002#msg-144002 www.toolstation.com]

Yep, Radio Shack used to have those years ago and I still have mine (made it through the 2006 apartment fire where I lost 60% of my stuff).

Where can one get such tapering bits?

I ground one 3mm drill bit with an angle to create a 1.5 - 3mm taper but it needs more work along the flutes otherwise the friction turns the stainless steel barrel red and, if held for long it deforms it due to the high temperature developed.]]> dzach General Sat, 21 Jul 2012 20:27:40 -0400 https://reprap.org/forum/read.php?1,143960,143981#msg-143981 https://reprap.org/forum/read.php?1,143960,143981#msg-143981 -------------------------------------------------------

I like those plans a lot so I will look around for the parts to make one. Figure 12v at 14.7w should take me to 320c.
