Filament test reviews for 3D printers: PLA, PLA +, TPU, PETG, Carbon ... The best in 2020?

[Christophe]

For those who have a FDM molten wire 3D printer, here are the recommended filament brands and those to avoid ...

So I answer Pétrus's question about this related topic: 3d printer and health

I am very interested in your feedback on the different brands of filaments

Here is my feedback in only 3 months and about 3kg and about 400h of various prints on the 3D Filament brands on my Tronxy: 3d-printers / tronxy-x5sa-500-pro-improvement-z-axis-how-to-paste-a-toothed-belt-t16537.html

Purchased exclusively on Amazon, so you will easily find these references if necessary:

- Amazon Basic PETG: very average, lots of hair, poor layer adhesion despite many different settings (but I haven't tested other PETG brands yet) 30% of the coil remains (blue)
- Sunlu PLA +: good but not so "more" than that for the more I expected more improvement (almost the same as PLA at the level of surface quality ... odors in PLUS ... well yes it is MORE fragrant what!) but the parts seem a little more resistant anyway
- Enotepad 3D PLA Carbon fibers: good but impossible to print durably in nozzle of 0.4 (hardened) and 0.5 (stainless steel), must print in 0.6 (stainless steel) otherwise it clogs (I am in bowden, not direct drive therefore, the extruder is deported ... I not know if that counts in nozzle clogging but certainly a little).
- Multicolored 3D PLA Enotepad: Ok, the spool is at 20% without much problem.
- Xingtong Zhi Lian Technology transparent PLA: Ok, the reel is finished, no big problem except that it was never transparent (whitish)
- Xingtong Zhi Lian Technology PLA Wood: there is real wood in it (20 - 30%?) you can feel it during printing. the filament is brittle and unusable on my machine
- CREOZONE TPU black: i only printed one small piece which looks ok but has quite a bit of hair. I printed at low speed (30 mm / s of memory, the tronxy allows 100 mm / s) and it is ok despite the remote extruder (a lot of people say that it is not possible to print TPU without direct drive)

To summarize, I would therefore advise against the brands: Xingtong Zhi Lian Technology and Amazon Basic. With a slight downside on Amazon Basic as long as I haven't tested other PETG filaments.

For the rest it's kif kif.

Coincidence, there is precisely a poll underway on this FB group:

After that you should know that:

a) One printer is not the other and a filament that can work well on one may cause problems on another model.

b) It seems, according to the comments, that there can have temporal variations of quality on the same brand ... (quality of manufacture variable in one direction or another)

c) Some filaments are hygroscopic, so they must be stored away from air. The best is to systematically protect them all.

My winding problems?

On all brands.

There it is sunlu

The previous one was also a brand thing, but I don't remember which one

[Christophe]

Weird I've never had one ... yet ...

Sunlu is rather famous as a brand ... but your mechanical modification solved the problem?

The mechanical modification solved the problem of driving the extruder of a wire coming from the top.

It is described in many videos on the net.

As now the wire is at the same level as the extruder no more worries.

There remains that of the winding.

When I am there I go to see regularly.
When I'm not there it's haphazard

The problem occurs rather at the end of the reel

[Christophe]

Ah ok I only finished one reel for the moment ... My fingers crossed.

My spool is at the bottom, the extruder at the top (60 cm higher anyway) and I tried to align well as much as possible (since this necessarily varies during the unwinding of the wire ...)

If I have any concerns I would modify to bring the coil closer to the extruder.

ps: the modification we are talking about is presented here 3d-printers / marvelous-technological-advancement-but-t16549-50.html # p414953

Arrival of the day 5 kg of new spools / new brands:

- PLA Filament 1.75mm, GIANTARM
- PLA Filament 1.75mm, ERYONE
- Carbon Fiber PLA, TECBEARS
- Carbon Fiber PLA, SUNLU
- NYLON Filament 1.75mm, TECHNOLOGYOUTLET

It will take me a long time to give you a feedback on these 5 reels ...

The kg of Nylon (apparently one of the best plastic for fdm) is normally sold over 50 € or even much more, like 40 € for a 0.5 kg spool (ouch ...) this one cost around 50 ... so if it does not give good results we will know why ...

[Christophe]

I just started a new coil:

- PETG White Makeasy

I'm still on the raft but it already looks much better than the Amazon basics PETG where I had struggled like a p..c just to make the layer of grip ... or so I became better in the settings ? No the filament looks better ...

The rest in 12h!

I noticed PETG doesn't like fingerprints, PLA doesn't care

I put a lease before understanding, as soon as I have a PETG print I clean the tray with dishwashing liquid I dry, without putting my fingers on it and hop no more worries for 6 months now. I have a Prusa MK3 a racehorse in precision normally.
As long as I used the PLA never had any problems.

I'm a little annoyed I just received this evening an Elegoo mars pro, small size but good another world ...

A ++

[Adrien (ex-nico239)]

I had to stop with the sunlu started because with 7 hours of printing it would have to be long.

I received 3 coils: basicfil, another sunlu and a 3rd whose name I forgot.

I had to do 15 times 7 hours with the basicfil without worries then I had a problem.

And there I struggle to get off on the right foot without really knowing where it comes from: maybe the level of the bed, well I do ch ... at least 5 or 6 blockages and therefore unexplained interruptions.

It's a bit of a hassle when it doesn't work.

[Christophe]

I'm a little annoyed I just received this evening an Elegoo mars pro, small size but good another world ...

I've had classic March since the end of June ... I'm more than 95% successful with print, the failures were my fault (over-optimization).

If you want advice, no problem (however not here: make a new dedicated SLA topic please)

On the other hand, it is not to criticize your choice but from what I read the march pro would have less good reputation than the classic.

The mars pro 2 has just been released too. No doubt to compensate for some flaws in the pro?

Didn't understand your imprint story? Are you talking on a glass platter?
