Now shipping, mine just arrived. I've only done a couple of prints, but so far It has worked really well in my Afinia/Up Plus (mine has the pen clip extruder / air cooling mod).

I have been testing the Taulman 618 nylon on my Up! Mini. It prints really cleanly and the luster and detail is in some cases better than the oem abs. I have experimented a bit with extruder temp. I started with stock (260-270C) temp and the material was incredibly strong, but extremely hard to separate a raft or support material from it. I went down to -30C and it extruded very pretty with great detail, and the raft would come away cleanly and easily, but when I flexed it really hard it would crack and delaminate. Now I am at -15C and its strong, but the raft is still too tough to remove. I am next going to test -20C which is where I think the best setting will be.

This stuff at the right temp is crazy strong and its luster reminds me of a Stratasys natural part.

Changing temperature on an UP?? How do you do that? The only option I know of is choosing ABS or PLA.

The temp control for Up! ------> How many different way to do it?
Hope Nylon material would be added to software setup ;).

Looks like an interesting material but at US$47 to post to UK it would be an expensive experiment. Anyone know if there is, or is likely to be a a UK distributor?

cheers

Sorry if I did not make this clear, but I have been altering the resistance reading from the hot end to the controller board. For roughly every 1 ohm of increased resistance, the actual extruder temp drops 3C. From my prints it looks like the best setting for the Taulman nylon is to add 8 ohms of resistance, which lowers the extruder temp by approximately 24C.

Just to be pedantic - 8ohms will reduce it a fraction under 22degrees i.e. approx 2.7 ohms/degree seems to be a more accurate assessment based on the work of others. I've not yet tried such shenanigans myself :)

Did you notice where I said 'approximately''? BTW, not to be pedantic or pompous, but Id like to point out in your post above that you say '2.7ohms/degree'. You clearly have reversed your ratio as it would more correctly be 2.732919254658385093167701863354 degrees celsius per ohm, and not 2.7 ohms per degree. Happy holidays! 8-)

Indeed, it is back to front, conversely and counter-rotated - I mean about 2.7degrees/ohm. I wasn't picking on your numbers by the way (I didn't even verify them) I was actually giving the figures from the lookup table for the temperature probe. I thought others might find it useful to have the more accurate figure although using the lookup table directly probably gives the best results. I rounded from 2.696something.

^ :roll:

Anyways... I just ordered some of this stuff, excited to try it out. :)

Wouldn't Nylon be more "food safe" than PLA? I'm curious.

You'd have to ask Taulman as it depends on the specific formula of his Nylon filament. Nylon can be both food safe and horribly toxic due to additives.

618 is "inert" to the body, but its not FDA approved, as certification costs too much.

There will be a medical grade nylon called 680 released in the future (could be a year or two away). It also won't be FDA approved, however it will be allowed in the body as a surgical insertion.

Bottom line. Its not approved for food use.

Afinia and UP! 3D printer users that want to print with the Taulman 618 nylon filament can purchase the Extruder Nozzle Temperature Switch for Afinia and UP! 3D Printers from Octave Systems. This enhancement to the Afinia and UP! 3D Printers reduces the nozzle temperature approximately 30 degrees C. Works great. You can purchase a Bundle that includes the 618 nylon, the temperature switch and a Garolite LE printing plate, which is preferred for printing with nylon.

Glad you guys are trying this out. I've been thinking that printing Nylon would be cool. My concern has been how to clean the nozzle/extruder if it gets clogged. I don't think Nylon dissolves in Acetone.

IYes, I was concerned about that as well, but I've been printing with nylon for a few weeks now, and have gone back and forth between nylon and ABS a few times using the same nozzle. So far (knock on wood) no clogging issues. Since Nylon has a lower melting point than the Up's ABS setting, I think it gets pretty well flushed out by extruding material at the higher temp.
