Annealing 3D Printed Nylon for high temperature resistance? Can it be done?
I have some Carbon Fibre (fiber) Nylon which I need to use in a high temperature (120degC) application, will it be suitable and can it be annealed to improve it?

I print that same SainSmart 25/75 ratio CF Nylon on my Ender 3 Pro. Micro Swiss all metal hotend, Marlin firmware (max temp set to 315C/ bed max temp set to 110C), 270C nozzle, 60C or 70C glass bed with glue stick, 30 to 40 mm/s print speed, 100% infill, .4 nozzle with .4 line width, .20 layer height, use a raft for easier part removal from the bed, printer is in an enclosure. Makes beautiful strong parts. Layer adhesion is amazing if the filament is dry and printed at 270C or higher. 260C and below, the layers would just come apart.

Hi Salty steel, thanks for the comment, I have heard a couple of place now this filament likes 270. Anything below 250 and I saw the layer adhesion issues, but because mine is “stock” or at least lightly modded, I don’t know how good it could be at 270degC (and I’d expect the enclosure is making a difference). To be fair, my Ender is likely to end up with a better board/firmware and in an enclosure so I’ll see the difference eventually! What type of parts are you making with the filament, I am always interested in functional parts...

@@MakingforMotorsport I've just recently upgraded my Ender 3 Pro to print CF Nylon and I picked up pthe same SainSmart 25% CF Nylon. I have the soft reflective fabric enclosure and I have an incandescent lightbulb suspended from the top to act as an enclosure heater, and with a temperature tower tested and confirmed, I actually find this stuff prints comfortably at 240~245c. I print [AMERICAN] parts on mine, so I can comfortably attest that it can handle high temperatures and high impact, so far I've been very happy with it.

For a annealing you need to pack the parts in cornstarch and then slowly heat to temp and slowly cool. Corn starch cleans easy and doesn't burn until like 1000 degrees.
These videos were exactly what I needed, thanks! Ordered some carbon filled nylon(Fiberforce Nylforce, what was readily available in Norway), a Micro Swiss all metal hotend, and a glass bed.

A while back I ran model airplanes with rather hefty engines and nylon props. During startup, you would tune the mixture screw while holding the plane straight up at full throttle and get the mixture perfect. What you didn't want was an unseen crack in the prop to let go and spear you with a blade. We annealed new props by placing them in a pot full of boiling water for about an hour. Made them noticeably softer and more flexible and much tougher. I am setting up for nylon, but it is taking some time. I want to make a pressure bottle and hook it up to the compressor and (with the bottle on the far side of the garage) pump it up to max on a hot day and see what happens. I suspect that 3d printed nylon will never be close to injection cast nylon for strength. Each pass of the print head could create a weak spot which could let go under stress. I have do some vacuum manifolds and had to coat them with epoxy to keep them from leaking. I doubt that would be a problem on car manifolds.

Interesting, thanks. I'm currently experimenting printing some unavailable electrical connector housings for use on an engine from non CF reinforced nylon. It's stiffness and toughness change quite dramatically (toughness increasing, stiffness decreasing) as is absorbs moisture from the atmosphere in the first few days after printing. The moisture acts as a plasticiser apparenltly. Therefore if you do any further tests, I'd recommend leaving them to absorb moisture naturally for a while first, as this is probably less noticeable with the stiffer CF filled stuff, but will still be happening, and could have a big effect on stiffness in a real works application with a load on it, like cantilevered manifolds. Boiling, as others have suggested can apparently crack some nylon 3d prints - I've not tried it.

Thanks for this. I'm making a intake manifold adapter for a boosted car (mazdaspeed3) and I chose CF nylon 6. Max temp it will ever see is ~100C coming from the head. Hopefully it holds 20 psi of boost but it will defiantly handle the temperature. I'm going to Anneal the part around 120C or so just above the temperature its going to see to hopefully prevent creep over time and from the many heat cycles it will see. I added 3mm wall brass bushings where the bolts will be going through the part for extra strength.

Maybe think about two more parameters when annealing: is the chosen temperature close to the melting point of the plastic? If not, you may not be doing anything to the microstructure. And also think about cooling rate. You can introduce new unwanted stresses into the part if the cooling rate is fast.

Hi Santiago, that is a very interesting point and some major Materials Science piece, but on reflection I am not sure I achieved much of a change in crystallinity, as there was little change in the size and properties. Therefore there are 2 options, this blend of Nylon doesn’t respond to annealing or it was already annealed by the heating of the bed and the slow cooling, I prefer option 1. As for change in properties of “dry” vs “saturated” nylon, that’s something I don’t have a feel for..... might be worth a test!

Running well… no thermal issues at all… I should say that 260f is beyond what I run to tho…
Next question: do you need the carbon fibers since all they are are bits of fiber vs lines

You’d be surprised the difference the CF makes, to the overall stiffness but also printing, regular nylon likes to warp but this is soooo much better! Also, I think the Cf is helping a lot with the higher temps. My favourite filament! All that said, it doesn’t compare to proper CF tow in a proper matrix and resin like conventional CF, but I’m still glad to have it!
Wow so creative which 3D printer did you use to print those parts ?

For this I used my Creality Ender3 Pro, lightly mod’d, there is another video on my channel on that!
Almost scientific except for you used 2 nuts on the samples rather than the 3 nuts before annealing. I know it requires a lot of time but we don't truly know if annealing actually helped with the CF nylon, or if it did how much

10 points to you! 1,458 views and you are the first to notice and comment! I noticed when doing my watch back before making public but decided it wouldn’t change the result much with this test, I would need a lot more load than just 3 nuts to show a result at a lower temp. I learnt the main lesson that it stands up well to the 120degC which I needed. Tell the truth, I don’t think the was any increase in crystallinity as dimension change is a key indicator and these just didn’t change at all. Makes me wonder if it was annealed during the build plate cool 🤔 I do want to repeat this test but measure the deflection properly with a dti to general a proper curve but other projects are calling. I may return to this in a few months with a better test setup...
How well do you think this would work out printing an entire intake manifold My plan is to make an gm ls intake but am afraid of the pressures and heat

I have printed an intake manifold out of it and plenty of others have too, I don’t know of anyone using it in a boosted application yet… Plenty of vids around on it (I have a few 😉)
Didn't watch the video but the answer is no. You need a crystalline plastic like pla for annealing to do anything. Asa or abs are also uninfected by annealing.

Maybe you should watch the video. Nylon is semi-crystalline and many grades react very well to annealing….
what nylon filament do you recommend for making a power steering piece? Also do you have a link to the filament.

Not sure I’d recommend any kind of 3D print for steering... steering and brakes really are safety critical. Which bit are you making? I can’t put external links here but I got mine from Amazon...

Was that a nylon 6 or 12?

ePA, so no particular proprietary blend like Nylon6 or 66 or 12 etc
Did you try ceramic dip?

Not yet, 2ndary coatings are on the list to do, but if I can get away without post processing I will…
Nylon needs to be annealed in a Nitrogen Atmosphere (Air has water in it even at high temps) you can also anneal it in oil also you anneal it for 30min per 1/4" of thickness (little over 6mm) at 375F also when taking out drop temp 50F every half hour.. not every plastic is the same as you are aware, neither is there annealing process!! please stop treating it like PLA
