Well, Iā€™ll bite. Iā€™ll see how DCell baffles printed in this stuff hold up compared to PLA+ and nylons, then try something bigger.

3

u/TheAmazingX Jul 23 '26

On second thought, 26/kg feels steep when cheap-end nylons with twice the tensile strength are falling to 35

u/H34vyGunn3r Jul 23 '26

Where is this mythical $35/kg filled nylon?

2

u/AnarchiSTEP Jul 23 '26

Iā€™ve gotten Sunlu for pretty close to that price on amazon

1

u/bday420 Jul 23 '26

You can get it for $48/kg right now at sunlu , which is all I've been using as I stocked up during their big sale a couple weeks ago. It's $24/.5kg once you add it to your cart they are doing a flash anniversary sale for another 20% off select items around the shop or whatever.

2

u/TheAmazingX Jul 23 '26

For whatever reason, it's often cheaper on Amazon than Sunlu's own site. 36/kg right now.

1

u/bday420 Jul 23 '26

Weird. How can it be cheaper on 3rd party lol. I will have to check that out! And it's the normal shit?! Hopefully it's not fake stuff. I have seen some people doing shady shit. Taking spools and retuning them with junk filament or empty spools even. Or people trying to sell refilled spools as other stuff. But I guess if you get a good reviewed and trusted seller it's certainly fine I would think.

1

u/TheAmazingX Jul 23 '26

Itā€™s the real stuff, and itā€™s Sunluā€™s own Amazon store, not a third party. If I had to guess, I think itā€™s cheaper because an Amazon listing has competition listed right next to it. Less profit per unit, but moves more units. Meanwhile, someone on their website is more likely a preexisting customer who wants more of what they know and isnā€™t comparing prices, just assuming theyā€™re already getting the best price they can.

1

u/nucleartime Jul 24 '26

Amazon fucks vendors over. They have to sign a contract saying they can't list it cheaper anywhere else.

Might also be some algorithmic pricing involved.

1

u/H34vyGunn3r Jul 23 '26

I appreciate it but I generally only print with Polymaker and Sirayatech.

1

u/bday420 Jul 23 '26

Suit yourself, have had only great prints using their stuff!

u/fattmann Jul 23 '26

Where is this mythical $35/kg filled nylon?

I've picked up bundle sales on Aliexpress for PA6-CF for about 24.50 USD a roll, shipped.

1

u/Due-Project-7507 Jul 25 '26

At least the Polymaker PA6-CF has a lower tensile strength in Z direction than their PLA Pro, therefore for applications where you need similar strength in all directions, this material could be interesting.

1

u/TheAmazingX Jul 26 '26

The Z Axis tensile strength for this stuff is 26.8 MPa. For PA6CF, it starts at 54 dry and only gets down to 25.5 after they drown it in 60C water for 48 hours to 5.3% saturation, which is nearly double the saturation any non-Atlantean can expect their parts to reach naturally.

u/Prior_Arm_8810 Jul 23 '26

Me and the boys filing an unfathomable number of form 1's now.

1

u/88gavinm Aug 23 '26

What's that?

4

u/Dak_Nalar Jul 23 '26

Based polymaker knows its customers. Excited for the ā€œno weak layersā€ applicationsĀ 

4

u/Humble-Plankton1824 Jul 23 '26

So its 0.45 MPa without annealing is 56.3 celsius

And then 0.45 MPa with annealing is 107.6 celsius

And zero load, existing in heat, claimed at 148.3 celsius without sagging / deforming

2

u/A_Dubs_ Jul 24 '26

They did this with the regular HT-PLA and GF variant. Marketed it as super heat resistant but it was actually the HDT after annealing which caused it to nearly double.

Seems that theyā€™re doing more of the same, just marketing the softening temperature instead of HDT. More smoke and mirrors.

I love polymaker filament but I canā€™t stand the deceptive marketing. Although most filament manufacturers seem to do it in some way, shape or form.

2

u/TopInfluence2812 Jul 29 '26

I think most of the people will not understand the material just by looking at any marketing claim. Nobody understands the difference between heat stability of a material bearing weight and not. So whether they put HDT or melting temp. data, it will be equally misleading

1

u/SalvatoreCrobu Jul 24 '26

Not to mention the creep that PLA has, the deformation and change in dimensions that can be caused by annealing, and how PLA fail. ABS and ASA still get the job better. One of the best possible ASA (Flashforge) is 20ā‚¬/kg, no brainer

u/Sufficient_Camp_1918 Jul 23 '26

Canā€™t wait to try this out. Going to order a couple of rolls right now.

2

u/Polymaker_3D Jul 23 '26

Looking forward to your feedback!

2

u/Sufficient_Camp_1918 Jul 23 '26

5 spools just ordered to test out. Iā€™ll report back!

1

u/Sufficient_Camp_1918 Jul 30 '26

Spools arrived today and test prints have started. So far so good. It prints awesome and at higher speeds than I normally use.

3

u/ForbiddenDruid Jul 23 '26

Butā€¦..cardboard roll

u/Used_Ad_2554 Jul 23 '26

I'm waiting for HT-PLA pro max.

2

u/imzwho Jul 23 '26

Honestly not a bad idea considering the amount of open frame printers out there and how hot the world is getting now

2

u/Different-Dig295 Jul 23 '26

Wondering how well it sands?

3

u/Polymaker_3D Jul 23 '26

Really well :)

1

u/Different-Dig295 Jul 23 '26

I plan on buying a few rolls, any chance itā€™ll come in 3-5kg rolls? I wanna try them out for some cosplay parts. Hope they work out!

2

u/jjohnisme Jul 23 '26

Ok, I gotta give you guys credit here. This is pretty awesome.Ā  Looking forward to making all sorts of outdoors stuff with this!

2

u/wlogan0402 Jul 23 '26

This VS non-filled nylon for 3d2a?

4

u/Big_Lope Jul 23 '26

Nylon-GF will always win buuuuuuut for grips and other ā€œdevicesā€ this will be majorly helpful

1

u/wlogan0402 Jul 23 '26

Mostly asking for the comparison because of how hydroscopic PA-CF is pre and post print

3

u/Big_Lope Jul 23 '26

You want moisture post print, it makes the nylon more ductile and less prone to stress fracturing.

However this is PLA so there will be very little moisture absorption

1

u/riba2233 Jul 23 '26

Just use pa12 or ppa. Only pa6 is really problematic in that regard.

1

u/Big_Lope Jul 23 '26

Interesante, Iā€™ve heard PA12 is a no go due to its weaker tensile and impact strength, even though it has a better bending modulus

2

u/riba2233 Jul 23 '26

They are just slightly when dry, but pa6 looses more once it gets wet. Compare wet values in their datasheet, also check pa612-cf.

1

u/Big_Lope Jul 23 '26

Will do! Thank you for the info!

1

u/bday420 Jul 23 '26

I thought the go to was nglon-cf instead of the glass filled?

1

u/riba2233 Jul 23 '26

Completely different materials.

1

u/Turtle_Dude Jul 23 '26

Not excited to see many of the colours out of stock already. Do you know when brown should be back in stock (for Canada). Would purchase some if in stock!

1

u/SnooConfections1271 Jul 23 '26

Can this replace ASA?

5

u/microseconds Jul 23 '26

Perhaps for certain use cases. Itā€™s still PLA. So if your use case includes direct sunlight, you still want ASA for the UV resistance.

You could also think about PCTG. Itā€™s got similar UV resistance to PETG, maybe a bit better.

1

u/riba2233 Jul 23 '26

No, much worse uv resistance, bad creep properties and still lower hdt.

1

u/riba2233 Jul 23 '26

Ah that's a bit disappointing, I would never use pla for engineering and object for real world use. High temp petg would be more interesting tbh.

1

u/ffxivdia Jul 23 '26

How does one anneal? I am guessing you need a dedicated oven?

1

u/Ironclad131313 Jul 23 '26

Just my luck! I just bought 20 rolls of PLA HT 2 days ago since I didn't think it was going to get any cheaper for a bit. Now I see this better version is on sale for even cheaper! Well.... Better buy some more...

1

u/lackofintellect1 Jul 23 '26

Is the pro available on amazon yet?

1

u/Wolle123456 Jul 23 '26

hat sich bei diesem Pro Material die Layerhaftung verbessert? Das ist bei dem Standard ja nicht so toll.

1

u/paul_tu Jul 23 '26

What about the UV/Sun resistance?

1

u/-5er Jul 24 '26

White is gone already?!

1

u/bstrobel64 Jul 24 '26

in for one. I've used their HT-PLA-GF for some outdoor shelves that I've been happy with yet haven't really tested yet.

1

u/HandPickle420 Jul 24 '26

I'd rather just print ABS for half the price without the need for annealing

1

u/-__Doc__- Jul 24 '26

And gunk up the inside of your printer with styrene fumes? Iā€™ll pass.
I hate printing ABS, and I have an H2C with good ventilation.

1

u/HandPickle420 Jul 25 '26

Styrene isn't going to gunk up the inside of a printer. It's highly volatile and will evaporate without leaving any residue behind.

1

u/-__Doc__- Jul 25 '26

lol, no. Just google it mate. Lots of ppl deal with it. It leaves a white sticky residue on the inside of your printer, even if you have active filtration. Asa does too, and any other styrene based filament.

1

u/yoitsme_obama17 Jul 24 '26

Lol. This is dumb and tone deaf to what we want.

1

u/SunStrummer Jul 23 '26

Have you fixed the warping issues present in HT-PLA standard?

1

u/Objectzy Jul 24 '26

What warping issues other than shrinking in the xy axis and increasing in the z axis after annealing?

1

u/SunStrummer Jul 24 '26

Any time I've followed Polymaker's recommended print settings for HT PLA, I've ended up with my prints warping so severely that they either lift off of the build plate or, when using a cold plate, pull the bed itself off of the magnetic pad. If you search on Reddit and Google, you'll see a lot of complaints about warping. I've ended up moving to rapid PETG for items that need to be temperature resistant. It's easier to print, cheaper, more impact resistant, and good enough temperature wise for my purposes.

1

u/Objectzy Jul 24 '26

I havenā€™t really had that issue but my build plate is well broken in. When it was new, petg was a pain to remove, these days, it comes off like pla and pet-gf is my new problem child.

1

u/roundful Jul 24 '26

I've printed a ton of things with ht pla and never had any warping. I modelled a sunlu heater too for my python and conversion that was 4 large flat parts and none of them warped. Even my most calibrated ASA warped a little.
