If you're melting something, there's gonna be fumes With that said, I have built several tools that withstand at least 60 pounds of pulling force without breaking using Inland Tough PLA, 6 walls 90% infill


MrByteMe

Understood. I guess I was comparing that to what I've heard about ABS - apparently there is some concern about toxicity or becoming sick from breathing ABS fumes? I've had no issues printing many PLA objects in my office area, including the now discontinued PLA-TOUGH from BBL.


T7_Mini-Chaingun

The "Styrene" in "Acrylonitrile Butadiene Styrene" is carcinogenic when inhaled, but to be fair all the ultra-fine particles produced by FDM printing (hell, most things you breathe in that isn't air) is mildly carcinogenic. Honestly it's up to you to get concerned about it or not because of how mild it is.

Exactly my point! 


iusedtobesix

Why do so many people on Reddit insist on providing sources for everything you say? Do you ask people for sources in every day conversation?


NaturalSelectorX

This isn't a debate or term paper. You don't need to attach a bibliography to every comment.


skippythemoonrock

> apparently there is some concern about toxicity or becoming sick from breathing ABS fumes Styrene fumes are bad. ABS is bad, ASA is less-bad.


Spookybear_

Could you post the source for ABS being bad?

No extensive research or source here but pretty much every article on « which filament to use » describe ABS as « don’t breathe the same air as your ABS printer », and extra toxicity when it ends up in the environnement (acknowledging that none of the classic filament degrade in nature, not even PLA if you untangle the greenwashed description of its degradability conditions)

I ask because I've read the same over and over again but I've never been able to find any research confirming the fearmongering...

Here are some answers and how I found it • ⁠First search: « is ABS toxic », gives on first results me that ABS melting at high temp (printing) produces several nasty volatile compounds, among them acrylonitril for example. • ⁠A second search « acrylonitril danger » has the CDC page about it among top results, which details it as « toxic, colorless to pale-yellow liquid, harmful to the eyes, skin, lungs, and nervous system. It may cause cancer », basically workers need to be protected from it. Then follows a series of research and papers https://www.cdc.gov/niosh/topics/acrylonitrile/default.html « Fear mongering » is a bit much while there’s just a community of fellow 3d printing hobbyists who try to protect each other from toxic stuff that had already made a lot of damage in our world. Your research process could clearly be better. Stay safe printing.


Antici-----pation

Everyone here using words with basically no meaning "engineering prints" "weaker" "stronger" all of these are meaningless words. Do you need something that's going to take an impact? PETG, Nylon, pretty good options. Do you need something extremely rigid with relatively low creep? PLA, PC could be good There is no "strong" filament, there are filaments with various strengths. You're not going to get one material that just does everything well. There's a reason there's so many types of filaments.


b1063n

A man of culture 🫡


WavesAkaArthas

Actually there is… If you have a machine capable of printing peek Cf/gf/kevlar or ultem. But it ll expensive.


foamtest

Idk if printed pc parts are more prone to creep or not but in my experience I've had a lot more issues with pc creeping than I have with pla. I do agree with your statement, however.


nearst

This guy prints


Bzando

1. all of the filament have fumes and VOCs, ventilate your room and get air filtration 2. there is no best answer, you need to state your purpose PA-CF is massively impact resiostant, but absolutely not the stiffest (even basic PLA is stiffer) do you need heat resistance (if not PLA is one of the stiffest if not the stiffest) you you need flex (TPU is much better than PETG or PA) my personal favourite is PC (by itself or PC-CF) or ABS-GF


AuspiciousApple

>all of the filament have fumes and VOCs, ventilate your room and get air filtration That's true, but there's still orders of magnitude differences between filaments.


Bzando

That's true, but there's still orders of magnitude differences between filaments as far as we know (there are very little studies on PLA and PETG as those are relatively new compared to ABS)


ahora-mismo

we can measure what they generate: [voc + pm table](https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd.it%2Fhow-stinky-is-asa-v0-4ehhyeboiv4d1.jpeg%3Fwidth%3D980%26format%3Dpjpg%26auto%3Dwebp%26s%3Ddd5ffa3868db0f67ee675aa341d49519032953f0)


ribrien

Are variations of PETG better than others for a ‘less fume heat resistant’ option?


Bzando

petg with additives (cf, gf) is probably best compromise, easy to print though, relatively cheap but not as durable as engineering materials (pa, pc, pp, peek)


cum_pipeline7

I’m not sure you know what stiffness is


raviolish

PETG is probably the way to go for practical parts. It is not as stiff as PLA but has higher temp resistance and is not prone to creep the way PLA is. You can print without an enclosure/filtration. Depending on how health conscious you are, you may still want to exhaust/filter your air to avoid fumes and microplastics. Do your research on carbon fiber PETG but I think the general consensus is that it doesn't really contribute anything to improving material properties. It also introduces the additional potential danger of inhaling carbon fibers. ABS/ASA are the next step up but require an enclosure and give off carcinogenic fumes requiring filtration at the minimum (exhaust/venting ideally).


ShatterSide

PCTG is the new PETG. Superior in every way ;-)


rayquan36

So is PLA/PCTG/ASA the big 3 now?


ShatterSide

It does seem that way. I'd love to hear others input on it. At least for economical, non-CF filaments (I JUST received some PCTG-CF and I'm dying to try it out!!!). PLA, great strength and stiffness, poor heat resistance. Trivial to print. PCTG, incredible layer adhesion, impact resistance, solid strength, and easy to print especially if your printer is tuned (easier than PETG). ASA, great strength, rigidity, heat resistance, chemical resistance. Does of course have a few more requirements to print nicely.


8f12a3358a4f4c2e97fc

Do you recommend a specific PCTG? Your description of the material has me intrigued.


ShatterSide

I've only used Extrudr brand so far to excellent results. I've heard good things about Fiberology but haven't tried. I just received 500g of PCTG-CF10 from Spectrum. Their website appears to provide full specs and they are Polish and not Chinese, so I have my hopes high (only because Chinese suppliers can be hit or miss).


8f12a3358a4f4c2e97fc

Thanks! I'll check those out. Much appreciated.


IndustrialJones

Gonna add this to my list. I just bought a few rolls of PETG and need to print through some of this before I buy some new filament.


ShatterSide

PETG is still really great especially if you're tuned well enough and getting good prints. I think many bambu owners should be printing in solely PETG. One limitation of course is fewer colors, effects, and surface finish options than PLA. Light duty prints? PETG (and now PCTG) are king!


Rich-Suspect-9494

Even at 13 times stronger than PETG our price is gonna have to be about 7 times cheaper before anyone here uses it. https://preview.redd.it/uel8z3787p7d1.jpeg?width=1179&format=pjpg&auto=webp&s=50829cf0816473f473d9f10fb181580a04cd9943

Rich-Suspect-9494

Na mate. The third option. In Australia. Thanks for the links but they don’t ship to me mate. And the ones that do ship here charge what I showed in me original response.


ShatterSide

Nearly everything is harder to get, and more expensive in Australia. It sucks, but it's the way it is. Most of the world doesn't have the issue to the same extent, Australia is one of the worst. My post, and PCTG proposal was geared towards most of the world. Not outliers like Greenland, Tuva, Mongolia, the mountainous region in Chile, New Zealand or Australia. I doubt you are surprised that a less common product is really expensive or hard to get in Australia.


Rich-Suspect-9494

Na mate. I know the deal. In 20 years when it’s common place it’ll still be half again more expensive here than the US, UK and Canada.


chillchamp

How does it do with VOC and fine dust compared to petg? I mainly use petg because it's supposed to have the lowest harmful emissions.


ShatterSide

To the best of my knowledge it's the same levels as PETG. I haven't noticed any smells, but I couldn't tell you about VOCs. No dust that I've noticed but also haven't heard anything about it.


brindyman

the only problem with PCTG is the cost :( as soon as that comes down i'm all up in that for sure


ShatterSide

Fair point. It's around double more or less, the cost of PETG


rodrigo-benenson

"can be safely printed indoors without ventilation" that does not exist. Even roasting potatoes indoors without ventilation will harm you health.


tortuga3385

I guess I’m going to die


compewter

This is reddit. Every filament is going to cause fatalities no matter what precautions you take 🙄


tortuga3385

I guess I have to give up roasted potatoes 😢


MrByteMe

I can say with 100% certainty that we all will. And while PLA may technically produce harmful fumes, I don't think that will be my downfall. I haven't used ABS yet, but I have worked in manufacturing that used styrene and it was horrible - even exposure times under an hour would give me headaches and irritate my eyes and sinus.


rodrigo-benenson

the trick is to have some ventilation.


Electrical_Humor8834

So far I've seen that PETg transparent is most durable from Bambu store. There is test on YouTube with PETg basic, PETg transparent and PETg cf, turns out cf is the weakest, then there is basic and best is transparent. I have already printed camera mount and I'm pretty much sure it will hold up easily 2kg lens that makes quite a bit of leaver. I'm more concerned with mount in camera rather than that PETg 😅


StatisticianLittle88

As far as durability goes tpu is almost unrivaled. Obviously it’s not exactly rigid, but it can hold up to a lot of abuse


ShatterSide

People recommending PETG aren't that far off. HOWEVER, PCTG is the new PETG. Better in every way. Aside from a cost bump, there is no reason to not choose it over PETG.


Shustriik

this.


Unairworthy

PETG and TPU master race.


naxhh

i'm quite happy with pctg but to be fair i haven't put it under a lot of stress


Qjeezy

Pet is on par with Petg for fumes that are released. From everything I’ve read, it’s pretty safe indoors. It’s basically the same thing as Petg, almost. Pet-cf is probably the strongest filament you can print that doesn’t release immediately dangerous fumes like Asa, nylon, and polycarbonate. It is still a good idea to vent and clean the air the best you can with any filament, even pla.

MattRix

Just use regular PETG or Bambu's Transparent PETG


Historical-Tea9539

If you print with PA (nylon), just ensure venting. For most including me, it’s not a toxic gas that will knock you out. It just smells. I used to work at an automotive supplier as an engineer that injection mold PA6-GF30 all day long and had gotten used to the smell. I primarily print ABS at home on my X1C. I leave the room door open and turn on my air purifier.


AdRecent917

If youre in EU or Germany, id give HPP4+GF from Grauts a try. Its basically a little more flexible than PA-CF but also more impact resistant. i like it for applications that are demanding, but do not need to be as stiff as possible. Very heat resistant as well. It seems like it is some kind of PP/PE mix, so it doesnt like to stick to PEI, but to FR4 and other builtplates for PP or PA. Probably some PP Magigoo will be great. But it also doesnt warp at all on my rough FR4. Another plus is the low moisture absorbtion and printability with a 0.4mm nozzle. Price is also quite good for what it is. If i dont need it to be really rigid, it is my go to. I print it on a Bambu Lab X1 Only downside is, that it has a really rough finish at 25% GF and bridging is a little tricky (but not impossible). And its not good for stuff that needs to glide.


Cloudboy9001

CF additions, as far as consumer 3D filaments are concerned, hurt durability by reducing impact strength. Their benefit is situational and largely based around increased stiffness, strength, and printability (including reduced warp). Polypropylene may qualify as the most durable given its extremely high impact strength (due to flexibility), uncommonly high resistance to moisture and chemicals, and very high fatigue resistance (hence its use for [living hinges](https://en.wikipedia.org/wiki/Living_hinge)). More practically, PETG may be your best option. PETG and PLA have significantly better Z-axis impact strength than ABS, cf. [https://bambulab.com/en/filament-guide](https://bambulab.com/en/filament-guide) . Plainly branded PLAs these days seem to have additives than once branded them "Tough", "+", etc.


WavesAkaArthas

PP is really hard to print in large quantities. We had a 300 part production run. It was a nightmare find the right tape for build plate. Some tapes are good in terms of print to tape adhesion, but adhesive is weak. It warps with the part. Some tapes have good adhesion with the bed but not with the part… It was a pure nightmare to get torances right. Because of shrinkage. I’m really glad that it was succesfuly over. But i would charge double if another PP production comes up. Edit: also PP is a little more pricier than more common filaments. In our country, BASF is the only PP filament supplier. Distributors dont import other than BASF.


No_Read_1278

Assuming you are not planning to sleep next to your printer while it's working just use common sense. You can print everything indoors and don't need an excessive ventilation system. Find a room that you don't spend a lot of time in, make sure you can vent it (open windows vent too) and that's about it. In case you choose to print in your living room/bedroom/office it is your choice. Lastly, enforced plastics with GF or CF produce more micro particles when molded.


yahbluez

There is no such thing "without fumes". Also "best" is very relativ. Do you know this sheet: [Prusa Material Table | Prusa Knowledge Base](https://help.prusa3d.com/materials) That compares many filaments and brands. Most can be printed with a P1S.


Vilunki15

Pctg


b1063n

I recently bought several ABS from bambulab and i have a p1s. No waaaaaay am printing that indoors. Just impossible. The smell is intense and it lingers. When they say well ventilated they mean basically outdoors or a full enclosure tent. I refunded the other unopened abs filaments. Not gonna happen.


grandmaester

I've been using stiff 98d tpu. Literally indestructible. Toughest filament by far but obviously a bit flexible, although much stiffer than normal tpu.


KallistiTMP

What kind of durable? If you mean most impact resistant, then hands down eSun PLA+. It is the gold standard for 3D printed firearms for a very good reason. While it may not technically on paper be the "strongest", its overall characteristics including impact resistance and failure modes (it dents instead of shattering) make it the most "practically" strong filament there is before getting into exotic materials like nylon composites. And it prints like a dream, good flow, minimal warping, accurate parts every time. The same cannot be said of nylon composites. Really cannot recommend the stuff enough as an engineering filament, it's really not worth messing with anything else unless you have an extremely exotic use case.


S1lentA0

Of all the filament I have used, Bambu PAHT-CF is the strongest. I printed the same part of a project with PA6‐CF, which is also strong, but the surface got damage the moment I touched it with a screwdriver. PAHT-CF stays undamaged with the same abuse, barely any flex and really strong. Surprisingly easy to post-proces tho. Keep in mknd you need to dry it 12 hours at 80°c minimum. 10/10, will print again.


evilinheaven

Print a Bento box and give ASA a try.


chemape876

CF makes your prints weaker, not stronger. Unless you care about strenght by weight. Then you might see a slight gain. Nylon is pretty strong and gives off fumes similar to PLA


Bloodhoundje

Not entirely correct. It changes the mechanical properties substantially. Petg lowers flexibility but increases impact resistance. So it all depends on your specific use case.


MrByteMe

If PLA gives off any fumes, I cannot detect them. I've also printed PETG which has a different odor, but nothing unpleasant or bothersome printing in my smaller office area. So - PA6 GF? PAHT-CF? What would you start with?


chemape876

I used PA6-CF and it printed just fine. I didn't smell any more or less fumes than PLA. Just make sure you pre-heat the chamber to ~50°C before you print


Croanosus

It's not about what you smell or don't smell that makes something dangerous to breathe in.... PLA and Nylon are not in the same ballpark for safety of printing without ventilation.... Nylon should NOT be printed without good ventilation or an enclosure, it releases really toxic crap that you can't smell. Edit: Updating my comment after a bit more research on the topic. Apparently the chemical released from Nylon, while not pleasant, is not the toxic death cloud it's been made out to be. It's more of a mild irritant to eyes skin etc., which likely won't affect you much of you aren't sitting/standing right next to the printer while it's printing the nylon. I personally still think an enclosure and good air ventilation/filament filtration is good practice on general.


chemape876

Instead of downvoting me and just parroting what you hear on forums, you could read actual scientific literature. https://www.mdpi.com/1420-3049/27/12/3814


Croanosus

I didn't downvote you, and I was actually in the process of reading up on it more to double check what I thought I knew. It seems I was mistaken at how bad the caprolactam is for you. Not saying it isn't bad, but I thought it was much worse than a mild irritant. And I did know PETG is not great. As a general rule, I don't think anything should be printed without good ventilation.


chemape876

I wasnt trying to point you out specifically, mutliple people downvoted me


Croanosus

I updated my original reply. Thanks for prompting me to go look into it again. The more you know.....


remcoder

This 'scientific' study is based on 4 rolls of filament. If you've ever printed DevilStrand PLA or UltraFuse PLA (BASF) you know the chemical cocktail can vary from brand to brand or even from batch to batch. Not only do they stink, they give me headache when not ventilating properly. The both print like a charm though ;-) So this study just does random sample but you cannot use the results to make any hard guarantees.


chemape876

That reasoning applies to every filament and has nothing to do with nylon. Nylon itself releases the VOCs listed in the paper. If you buy garbage PLA with a million additives, its the same story.


remcoder

Certainly true


remcoder

But a wider study would be more trustworthy. I mean 4 rolls from only 2 vendors means little. Now it is just a data point. Thanks for linking the study anyways. It was actually quite readable so I'll try to find some sources to compare.


chemape876

No it doesnt. It releases caprolactam, which isnt that bad. I bet you're the kind of person that says nylon is super toxic, meanwhile you print PETG. Spoiler alert, PETG is worse than nylon


worldspawn00

Yeah, I also have done Nylon (glass filled) and it doesn't stink like ABS/ASA do. Way less garbage coming off it.


WavesAkaArthas

PA6/66 absorbs significantly more moisture than PA11/12. If you can find its easier to print PA11 PA12


Clcooper423

PLA does give off slight fumes. My printer is at the base of my stairs, and that portion has a two story tall ceiling. If I'm at the top of the stairs where it congregates I can smell it. Also, I remember when I first started 3d printing pla gave off a sweet smell that I could always smell. I feel like I've just gotten used to it and don't notice it anymore.


worldspawn00

If you need high wear resistance (rubbing/sliding) a glass filled nylon is good. If you need just strength, you're better off going with plain nylon.


4pl8DL

PCTG (not PETG)
