Nylon. How and WHY?

Okay, the topic says all.  Somebody speak nylon to me.

Low effort post, meet low effort response. Were you after anything specific?

Really?  An article older than two of my grandchildren. Nice.

Perhaps, wrong printer, wrong crowd.

Give a hint as to what information you're after, and you'll get better answers.

I am moving on from everyday feedstock.

does anyone print nylon? Which?  Moisture management?  Build surface?  Is this printer up to the task?  What does nylon offer that other plastics do not?

not sure what I didn’t convey. Verbosity is rarely a virtue. If you print nylon, I would like to hear your thoughts. If you don’t print nylon, it is an error to think I cannot google.  

Not much to be found here just searching for nylon.

RE: Nylon. How and WHY?

I thought you'd posted on printing on garolite, so can we assume you're familiar with the primary issue of printing nylon on a Prusa: The need to find a suitable print surface? Garolite should work well. I've done a bit of printing with a slathering of gluestick on the Prusa smooth PEI sheet, but it's not ideal. Have a garolite coated sheet but haven't used it yet. As the old but still informative article notes, the stuff loves to suck up moisture, so be ready to dry it thoroughly and frequently. 

There are lot of possible topics relating to nylon, so it helps to know if you're looking for characteristics of the material, how to print on a Prusa, post-processing, available finishes, and so forth. Taulman Bridge is a good formulation for getting started with. Taulman 230 is also interesting and, in theory at least, easier to work with. I haven't ventured into the more ambitious nylon blends myself. I'm planning on using it for some outdoor projects where the flexibility and slipperiness are a plus such as table inserts for umbrellas and that sort of thing. Just so happens that I am experimenting with using Bridge for a project now.

Nylon does not have great high-temp characteristics, so may not be suitable for car interiors or direct sunlight exposure. Old as it is, the MatterHackers article provided me enough info to start playing with nylon. Hopefully somebody who's done more with it can help you if you have any specific questions.

Never used garolite. A friend did.  Close to ordering nylon+ from builtak, but not convinced.  The concept of proper tools speaks to me, often quite loudly.

Titanium heatbreak, copper heat block, 3dmakersengineering full tc nozzles.  Hopefully that path is up to the task. 

I have a lead on a job for some nylon couplers for a beverage plant. Not sure it is a good idea. My interest is printing useful, functional things.

RE: Nylon. How and WHY?

The MatterHackers article does a good job summarizing the key benefits. Good inter-layer adhesion, flexibility, and abrasion resistance are the characteristics I'm most interested in. 

I've also got a titanium heatbreak and copper block, but I don't think they're absolutely required. Normal nozzles should work. I'm thinking a coated nozzle might be a benefit. I'm going to try prints with a 0.6mm nozzle for larger pieces. I don't have a heated chamber, so warping may be a problem for bigger pieces. The lower bed temps and higher ambient temps may keep me out of trouble. If not, I'll try some adhesion booster.

There are some decent YouTube videos comparing different filaments that you might want to check out.

Here's an item on the topic of printing with nylon that appeared on 'another network' a while ago:

No, never have.  I just thought the people here might be interested in this on-topic video that appeared on another forum.

Not trying to do either. Trying to find someone who prints nylon. Apparently you don’t either. 

I’ll figure it out just fine. Was hoping someone here could have some wisdom to share to save me some trouble. My error.

RE: Nylon. How and WHY?

I'm with bob on this. really you can't just get on line and learn something? if you want someone to tell you something new show us what you know, and I'll happily discuss what I know, prove to me I'm not wasting my time.

BTW @eric-e I like your scene of humor.

 

Good Luck in your education,

Nylon. Why not? (RE: Nylon. How and WHY?)

Amazingly enough, the advice on printing nylon from 2014 still applies. I guess filament isn't like an iPhone. You don't have to replace everything every year to hang with the cool kids.

I ran off my test pieces printing Taulman Bridge with good results:

I was pleased to find that M55x4 threads modeled in Fusion 360 work. Everything turns, though they do stick enough to require a good grip. The stuff is a lot like PETG that doesn't want to stick to the bed. Things that worked:

  • Printed Taulman Bridge nylon at 250C on a 45C treated bed with a 0.60mm nozzle with 0.80mm extrusion width. 
  • Printed on a cold (45C) bed with an 8mm brim. A bit of adhesion booster helps. I was printing on glass (on my Sidewinder), so used some VisionMiner Nano Adhesive formulated for nylon. Stuck almost too well. I haven't tested a lot of variations, but avoiding temperature variation between layers near the bed and those higher seems to have helped when printing without an enclosure. Previous attempts with a 70C bed warped badly at 5mm. The Bridge formulation probably helped as well, and not sure if I'd get away with no enclosure with a more demanding nylon on a cooler day.
  • Overhangs (e.g., threads) are difficult with no part cooling. Keep layer heights low (0.24-0.32mm high X 0.8mm wide extrusions with a 0.60mm nozzle) to avoid having overhangs pulling apart (e.g., inside of threaded nut).
  • Prints will have sharp edges. A pass with a deburring tool helps, but modeling in some chamfers or fillets is a good idea if you'll be manipulating parts by hand.
  • This stuff is as tough as advertised in a bendy way. I am unable to tear apart a 0.2mm printed sheet, nor am I able to get a stiffer part to shatter with hammer strikes (unlike PETG or PLA). I'm expecting Polycarbonate to be as tough in a rigid way, but haven't tried it yet.
  • I'm using these prints outside and will see how it holds up to temperature and sun, at least in New England.
  • No real differences from printing with PETG otherwise. 
  • No problems following my usual cleaning regimen for higher-temperature filaments.

This was a good confidence booster. Bridge only has a Tg of 52C. Taulman 230 nylon has a Tg of 68C and is advertised specifically for cold beds and lower temps, so might actually be a better "training wheels" nylon. Nylon 680 has a Tg of 93C, so may be better suited for outdoors, though UV resistance is not advertised.

I wonder if @cwbullet has tried nylon for his missile battery model rocketry.
