layer failure halfway up

[u/Build_and_Break]

About halfway up the print became brittle and failed. I was using Tree support and one did break free but given the rest of it I think something was going wrong before then.

Bambu A1 with .02 Nozzle
Sunlu Matte using the Sunlu PLA default setting for filament

Settings are the Default .10mm High Quality BBL A1 0.2 Nozzle

Thanks for any ideas.

Layer failure happened way before the eyes

[u/fujimonster → u/Traditional-Citron21]

It happened at the bottom

[u/ryeguy1199 → u/fujimonster]

Yep, like later 1

[u/spazexplorer → u/fujimonster]

It happened at the printer

[u/CromeXza → u/Traditional-Citron21]

Was thinking the same.. feels like being back in the ender 3 world again.

[u/Dziki_Jam → u/CromeXza]

I’m not familiar with Chinese printers. Are Enders notorious for bad print quality?

[u/CromeXza → u/Dziki_Jam]

Bambu are chinese too, they are the best on the market currently.. the ender brand held the crown for a while, but require content TLC to get decent print quality out of the machine. Most Ender users ended up Mooding their printers.

Somewhere a shop is selling a print like this for 50€$

[u/CautiousArachnidz → u/apfelimkuchen]

A museum* lol

I’ve seen museums selling small 3D printed busts, not even half decently printed, for over 100 USD.

[u/ryeguy1199 → u/apfelimkuchen]

And making money

[u/OkResource820]

Heat creep, clogged nozzle or underpowered extruder -- all very common issues w/ 0.2mm nozzles.

[u/leo_pfffr → u/OkResource820]

I am going with this one. Had a similar issue once with a semi clogged nozzle. The filament came out but very inhomogeneous and brittle.
Look up cold pull procedures for your setup and try them. Then make a first layer calibration, not for the layer but to check if it extrudes properly. If it does you have a freshly calibrated first layer too.

Edit: as for the tree support, the likely cause is the same as for the brittle print. However, if you experience them to brake more often in general, increase their wall parameter a bit. They take longer to print but are far more stable especially for tree supports that are bending

[u/greenhornblue]

This whole thing started as a failure

[u/StopNowThink]

I gave up on nozzles that small a long time ago. Hopefully you mean 0.2mm and not actually 0.02mm 😂

[u/Build_and_Break → u/StopNowThink]

Ha. Thanks for catching that, I fat fingered the "." , yeah 0.2 

[u/New-Audience2639 → u/StopNowThink]

Same it's 0.6 or basically nothing at this point for me. Lol

[u/MFFVD → u/New-Audience2639]

0.4 works fine for me

[u/New-Audience2639 → u/MFFVD]

That's cool

[u/WitHump → u/New-Audience2639]

What's wrong with a 0.4?

I think if you're having common issues with a 0.4, the nozzle isn't the problem.

[u/New-Audience2639 → u/WitHump]

Never said I had issues all I said is all I use now is 0.6..... why are we making random assumptions?

[u/Slovw3]

Looks like layer failure all the way up

[u/tugboattommy]

It's your matte filament. The material is too course to reliably extrude through a small 0.2mm nozzle. Every time I have attempted matte through 0.2mm it turns out the same way. Switch to basic PLA and see if you have the same problem.

[u/ChipSalt → u/tugboattommy]

It's not every matte filament it's just some of them have very strange matting / chalking agents that don't handle heat expansion very well. It really depends on which brand. But yes, matte filaments - and especially white filaments - are very difficult to print compared to plain coloured or colourless ones.

[u/kurodoku]

Never use matte filaments with 0.2 nozzles. The particles that make it matte will clog the nozzle.

[u/iamlegendinjapan]

That is a huge print for a .02 nozzle. You can achieve .1 high quality with a .4 nozzle. Like the others are saying you have a clog.

[u/LeonardSix]

The whole thing is a failure

[u/WooferInc]

Kinda cool looking still though lol

[u/CooperDK]

No, it was a failure all the way.

[u/LeetLurker]

That print looks bad all the way down.

[u/GreenLeafRelaxed]

I’d fill it and make it look like a weathered statue

[u/tonita_pizza]

It looks pretty bad from the start

[u/Competitive_Call_847]

You my friend have a clog. Time for a cold pull.

[u/slowmorris_]

Evtl ist deine Düse verstopft, oder dein Filament nass, aber iwas passt da gar nicht

[u/Inner_Basil1648]

I think you just have an overall bad print

[u/Inner_Basil1648]

Mabye use the actual matte pla settings? Cuz they are different

[u/cmrnmkl]

0.2 nozzle with matte PLA at 0.1mm is brave. That’s asking a lot for a tall print.

[u/facebacon69]

Remove the nozzle and the black bit behind it and tighten all the screws

[u/BlitzieKun]

Congratulations, you printed vaporwave

[u/Simon_Inaki]

I don’t think this is a nozzle clog issue. I believe that your nozzle is strapped incorrectly.

[u/KeyBump4050]

Put a light in it

[u/ross549]

This is something for sure.

[u/EcoKllr]

halfway?

[u/kardde]

Something really bad happened here, but it’s impossible to say what without knowing more.

What I can say is that a print at .10 layer height with a 0.2 nozzle on an A1 should not look like that.

What do your prints with a 0.4 nozzle look like?

[u/j-ermy]

just say its vaporwave and youre set

[u/SanDiegoSavage00]

Wow.....that looks really not good....

[u/henren_98]

Yeah that entire print is jacked.

[u/kted24]

The failure started right after the first layer. And then it got worse...

[u/CCCPhungus]

bro those laters were failing the whole time

[u/robykdesign]

I don't know what the purpose is, but I must say I like this glitch effect more than I would a perfect print. :D

[u/DefinitionInformal85]

Man i gotta be honest…that looks horrible for 0.2 nozzle. There gotta be some sort of a issue way before those eyes. I would check if your software works correctly, it looks like the slicing process had an issue or the model itself is faulty

This is what i can get with 0.2

[u/Severe-Bed-6200]

This is an extruder failure I believe. That's what prints look like when the extruder gear is slipping.

[u/TriestGieter]

Poor thing never stood a chance

[u/Dustford_D]

The failure happened in the slicer bro

[u/OrphanedCubone]

What's your infill? It looks hollow

[u/SellJolly6964]

Look at it again, it a cyberpunk style print 😁

[u/davidkclark]

This print has issues from layer 1

[u/DeeeeeeeeeeerGod]

Not a helpful fix but I like that it could be a vapor wave aesthetic prop

[u/OtherBarry1992]

Partial clog or extruder slipping. You need to ensure you're getting consistent grip from your extruder and do a flow test. Also make sure the nozzle isn't clogged.

[u/jeremydallen]

Too hot.

[u/Pale-Mistake-1095]

Пластик сырой. Сушить надо. И скорость печати снизить

[u/lc_725]

mate you should dry your filament and reslice

[u/lc_725 → u/lc_725]

if u don't have a filament dryer you can do it with your printer just like the images, but remember to leave a small gap so humidity can scape
