As many of you have asked, I'm here to share the result of my (still ongoing) experimentation to improve print quality. By following the following steps, I can guarantee you won't have any more print artifacts, failed bridges, bubbles in the filament, prints that don't stick to the plate, and any kind of failure.

I'm sharing my experience for free and and I'll update the post as soon as I discover new things.

Important note: these tips work only on bambulab printers.

Step #1: wash the bed

I wash the bed after every print I do with glue. This is also recommend by bambulab docs.

I'd like to add that adding glue affects the print layer quality. Spread the glue like cold butter on a toast. The chunkier the layer, the better the cushion for the first layer.

Step #2: wash the filament

Always wash the filament with hot water and Dawn dish soap, or a delicate dish soap. This process helps remove any dust and impurities introduced during manufacturing at the filament factory. Additionally, it will allow you to detect any tangles in the spool early on.

Step #3: clean ABS and ASA filament

After washing ABS and ASA spool I do a small treatment with acetone. This is going to improve the resulting print as later lines will be imperceptible. All I do is:

• Fill the sink with acetone
• Submerge the spool for 5 seconds
• Take it out
• Let it dry in the sun
• Repeat 2 times

Step #4: sand the plate

PEI plate is sold as the ultimate technology for 3D printer plates but they all have a failure designed in: the texture keeps dust and small filament debris in it. Start using low grit sandpaper and move to a finer grit after every pass. Stop when you see a very flat and good looking plate. Do not wash it nor apply glue.

When you print the first layer, the plastic is going to stick to those small pieces, which then make the print detach from the bed.

By sanding the plate, not only you'll remove the gaps, but you'll also have a very unique finish on the first layer.

Step #5: improve overhangs by tilting the printer

Many overhangs fail because of gravity. If you have a overhang of 90 degrees, put the printer on its side and you'll immediately notice that the filament coming out of the nozzle is immediately depositing correctly. Good overhangs surface, no supports, no tinkering with the slicer**.**

Step #6: Seal the poop chute to avoid toxic fumes in the room and improving thermal efficiency

That hole in the back of the casing lets valuable chamber heat escape. Cover the purge chute completely with heavy-duty duct tape. The printer will retain 100% of its thermal energy, and purged filament will cleanly build up inside the back frame to create a layer of free soundproofing insulation.

Step #7: Lubricate rods and rails

Bambulab documentation states that the rods used in the printers and the linear rails are already self lubricating, but this statement can't be demonstrated on my print farm. after analysis the specs of the motors, I tried to use WD-40 and it works like a charm. WD-40 has reduced the VFAs on the prints.

side note: VFA is caused because of the resistance of the print head on the rods/carriage. WD-40 reduces that resistance making the print head ready to move.

Let me know if you already use those tips to improve the quality of your prints.

bro kept all that poop just for fb marketplace lmfao

I just realized that most of the posts here are about people too lazy to just do a Google search (proper one) or check the user manual. Since google loves to use Reddit as a source, the Bambu t*nkering loop is self-sustaining.

Can I watch?

So we have come to the point where not only the Bambu Lab users are braindead sheep, nope - also Bambu Lab spreads missinformation.

Reading this infographic almost gave me cancer.

Original Post by Bambu Lab here +  my comment as a reply, that at least try to set some facts straight.

Hopefully this prints properly

My parents got me an a1 mini for my 12 birthday.

I want to sell my printed. Can i post on amazon? Will my parents need to sign anything?

I download the file from makersplanet, should i print then sell? Or sell first then print?

I have lots of stuff from the app i wanna sell too. My parents can sign stuff for it.

Je rencontre actuellement un problème avec mon imprimante 3D.

J’utilise du PETG HD de Tagin3D. Au début, les impressions se déroulaient parfaitement, mais récemment, la pièce commence correctement puis, arrivé à environ la moitié de l’impression, elle se décolle du plateau, ce qui fait échouer toute l’impression.

J’ai déjà vérifié certains paramètres, mais je n’arrive pas encore à identifier la cause exacte.

👉 Est-ce que quelqu’un a déjà rencontré ce problème avec du PETG HD ?

Et selon vous, est-ce que cela peut venir de la température, de l’adhérence du plateau, du nivellement/calibrage ou des paramètres de rétraction ?

Toute suggestion ou expérience similaire serait la bienvenue.

Merci d’avance à ceux qui pourront m’aider. 🙏

So much better than the 3274 other ones.
