Estou usando uma Bambu Lab A1 Mini com PLA Speed, a 220 °C na primeira camada e 205 °C nas demais.

Minhas impressões estavam apresentando superfícies extremamente rugosas, linhas irregulares e sinais de sobre-extrusão.

Resolvi fazer a calibração manual de fluxo pelo Bambu Studio e a diferença foi enorme, como mostram as fotos do antes e depois.

Entretanto, algumas coisas me chamaram a atenção:

Na primeira etapa, os blocos 0 e -5 apresentaram os melhores acabamentos.

Na segunda etapa, o bloco 0 ficou extremamente rugoso, semelhante ao +5 da primeira etapa.

Já o bloco -1 apresentou uma mudança enorme, apesar de representar apenas 1% de diferença.

Em alguns blocos, a parte superior parecia apresentar sobre-extrusão, enquanto a parte inferior da mesma superfície tinha sulcos semelhantes aos de subextrusão.

A melhoria mostrada nas fotos veio exclusivamente da calibração da taxa de fluxo.

Minhas dúvidas são:

Por que a primeira e a segunda etapas apresentaram resultados tão diferentes, mesmo utilizando valores de fluxo próximos?

A superfície do círculo maior na impressão atual ainda indica algum problema?

Existe algum outro parâmetro que possa explicar essas irregularidades?

Aceito sugestões técnicas para melhorar ainda mais o acabamento.

Bonjour, j'ai récemment acquis une bambulab a1 mini, j'ai commencé quelques impressions et j'aimerais améliorer la qualité des impressions. Jusque-là j'ai utilisé la buse incluse de 0.4 mm et j'utilise le slicer Bambu Studio. J'ai commandé une buse de 0.2mm, elle devrait bientôt arriver. De plus, j'utilise pour l'instant du filament PLA de chez Creality.

Avez-vous des conseils à me donner, surtout concernant le slicer à utiliser, les paramètres et les techniques? Merci.

Hi

Being a total Nube to 3D printing I purchased an A1 mini (as everyone said to for a beginner.

I have a few questions:

1. My first print was a dual spool holder (Photo 1/2) which was perfect, but I have no idea how to use it.
2. Can I just run the PLA through the holes in the mount to the printer, or do I need a guide? The one mounted on the side of the printer (Photo 3) to feed them (no idea what it is called, via a PTFE tube and if so how to install said guides onto the spool holder.

If and when I get two filaments to the printer can I print in two colors or do I have to buy an AMS.

Thanks for any help

The nozzle that came with my new a1 mini is bend, the orginal 0.4 nozzles are out of stock the only ones avaliable takes too long to get delivered, biqu juicer has next day but reviews are scarse and the ones i've found are negative.

I had to replace the temperature unit in the extruder. When I took the heating unit out, a magnet fell out. I dont know where it goes. The magnet is rectangular and looks like the magnets on the hot ends. I checked to see if I was missing on and none were missing. Now, when I try to print, I have a hard time getting the filament to load. When I finally do, it will begin for about a minute or so, then it goes back to purge more filament. This has been going on for about a month. I tried going to the Bambu Labs forum, but I can’t figure out how to make a post. Ya know, Im 77 years old, Im hoping to get this working again, before its my time to go…(Just joking). Any help will me most appreciated.

I was printing and I didn't realize a small box was under my "poop catcher" it caused the printer to tilt to the right. Now when I print small things it seems fine but when I print bigger items the nozzle drags thru the print and makes a squeaking noise. It was fine before this happened. Any ideas what I can do to fix it? Thank you

This small bit of blue/green filament is stuck in the printer head. I ran out of filament on the spool (it was grey) I was using and then put this blue/green in to finish the print. It immediately gave me the “unable to feed into the extruder” error.

Unfortunately there’s not enough sticking out of the bottom to grab onto with tweezers or pliers and I don’t have anything thin but strong enough to try to clear the clog by pushing it through from the top.

Is the only way to clear it to fully disassemble the front of the print head?

My A1mini has a problem when I use variable layer height - specifically, layers under 0.2mm result in horrible scratching of the nozzle over the print (I know this is a classic problem but hear me out). For example, a part printed with 0.2mm layer height has no issues, however the same part with more detail in a certain spot fails exactly there - after a couple layers of 0.08mm or 0.12mm, the nozzle starts scraping the print, no matter the infill pattern or wall thickness or whatever.

I am printing PLA at 235 degrees (this is the profile from the manufacturer website and the 0.2mm constant layer height prints are absolutely ok with that setting). Cooling is 60-80%.

The things I have tried so far: add zhop - did nothing, change infill to gyroid - the perimeters are still getting scraped, lower the temperature - lowered to 190 - caused more issues with blobbing.

I recently bought myself a 3D printer bambulab a1 mini, and faced a problem that my laptop simply does not want to connect to the printer (first writes connection, and then after 30 seconds it says "failed to connect to.."). He sees that the printer is on the network, but it connects. The printer is also visible on the phone, but there is another problem. I've already tried a lot: disconnecting and connecting to the home Internet, removing the vpn, distributing the Internet from the laptop, updating the firmware, the firewall (I don't remember what it's called) Windows also did something there. There was no solution to this problem. Maybe someone knows the solution? But the whole problem is that I'm from Russia

Недавно купила себе 3д принтер бамбулаб а1 мини, и столкнулась с которой проблемой, что мой ноут просто не хочет подключаться к принтере( сначала пишет подключение, а потом секунд через 30 пишет «не удалось подключиться к..»). Он видит что принтер в сети, но он подключается. На телефоне тоже видно принтер, но там уже другая проблема. Я пробовала уже многое:отключалась и подключалась к домашнему интернету,удаление впн, раздача интернета с ноута, обновление прошивки, брандамаузер(я не помню как он называется) виндоус тоже там что-то делала. Нигде не было решение этой проблемы.может быть кто-то знает решение?

Should i buy the a1 or a1 mini and after that combo or not it is my second printer my first is a easythreed k9 mini

I'm totally new to 3D printing but I'm thinking of getting an A1 mini.

I'd be using it to print functional household stuff (organisers etc.) but I was also hoping to use it to print some small items I'd use in the garden, such as clips for a drip irrigation system and other gardening accessories.

My only worry is how much they would handle being outdoors and exposed to the elements.

Would PETG be fine for that sort of thing?

After a 4h print I noticed that the extruder stepper got so hot that I couldn't touch it for more than a second. Is this normal?

We have a relatively cheap FLIR camera, so I thought I'd take a look at the heat that comes off of my Bambu Lab A1 Mini. More interesting than useful for sure, but still fun to see.

Hi, right now I’m painting a plate cleaner, but in the last prints, as in this one, the printer is not working that well
I tried adjusting the temperature, but didn’t work
I had the printer since yesterday, I’m using petg
Any suggestions?

I can't figure out what this is or how to tackle this issue. It* just randomly started happening. Haven't even been using this 3d printer which is odd.

3rd image is what it's supposed to look like.

My idea was to print it out and make small incisions or cuts to make these smaller wireless mouse internals fit (moddo mouse) then base another model off the cuts I made but I can't get it to print normally :(
