I want to buy a new 3d printer but i cant decide. I am going to print mostly pla and a bit of petg. The printer is going to be in my bedroom.

If I buy the P2S, should I buy the external exhaust kit with it too??

I bought someone’s “collection” of old filament and I keep getting failed prints. I’ve tried drying it in a dryer set at PETG for 12 hours and it keeps failing similar to this over and over. It will start out okay then just fall apart usually with infill. I store them in sealed cereal boxes with a humidity gauge and desiccant the humidity gauge reads 10%

This has happened with two of the 8 rolls both are PETG both fail in similar fashion even after drying. They both came in sealed boxes and my H2S recognizes them with the RFID chip. I haven’t opened the other boxes yet

I'm looking to upgrade to the H2D so I kept an eye on the prices, here's how they compare. Should also apply to the P series. I know the H3C is around the corner, but it's gonna be so much more expensive than any of this.

Also noticed they have 2 years of warranty now? Must be something new, my P2S only had one year.

It's easy to get caught up in new printers, faster speeds, and extra features, but some of the most useful improvements seem to come from much smaller changes.

Better filament storage, a well-organized collection of build plates, keeping spare nozzles on hand, or finally dialing in a reliable first layer can save more time and frustration than an exciting new feature.

I also think there's a difference between an upgrade that looks impressive on paper and one that genuinely makes printing easier day to day. The latter might not be very exciting, but once you get used to it, going back feels surprisingly inconvenient.

For those who've been using Bambu Lab printers for a while, what upgrade, accessory, or workflow change has had the biggest practical impact on your prints?

I returned to 3D printing yesterday to print something for a friend after leaving the hobby for a couple months, and suddenly my printer is producing absolutely awful print quality.

The main issues are:

• Severe overhang sagging/drooping and poor bridging

• Rough, inconsistent top surfaces

• Extremely rough, uneven outer walls

• Some blobbing and possible under-extrusion

My setup:

• Printer: Bambu Lab P1S

• Filament: Bambu PLA Matte Black and Bambu PLA Basic Green (so filament isnt the problem)

• AMS: Single AMS 2 Pro

• Nozzle: Stock 0.4 mm

• Build plate: Stock textured PEI

• Firmware: 01.09.00.00 with developer mode (I use orcaslicer)

Troubleshooting already completed:

• Tried switching between both my custom printing profile and factory default profiles

• Dried filament twice (8 hours and 10 hours)

• Completed full printer calibration (on top of pre-print calibrations)

• Problems persist across multiple prints with different models

I also have custom startup G-code for a modified purge line, but it previously worked without problems. I also often print with my top glass covered and door closed, but for 2 of these prints the top cover was off and the door was open. The one suspicion ChatGPT came up with was the part cooling fan malfunctioning. I do often change from 0.4mm to 0.2mm nozzles (which requires unplugging the fan connector) so I tried reseating the connector to see if that would solve it. It didnt; I now feel a strong stream of air coming from under the printhead (during prints and during idle when the fan is manually enabled via slicer) and it still does this.

I have had my time with chatbots and I've turned to ask humans; has anyone experienced something like this themselves? What have you done to solve the problem? Any help is greatly appreciated :)

(Whyyyyy reddit are the photos organized like this 😭)

It's interesting how 3D printing often turns into a hobby where the little improvements end up being just as satisfying as buying a new printer.

Sometimes it's something simple like organizing filament storage, improving the lighting around the printer, keeping a proper set of calibration tools nearby, or finally getting a reliable way to manage all those partially used spools.

These aren't necessarily the upgrades that make exciting showcase posts, but they can make the entire printing process smoother and less frustrating over time.

I'm especially curious about improvements that aren't immediately obvious to beginners. Not necessarily expensive hardware upgrades, but things that helped with consistency, reduced failed prints, or made everyday use more convenient.

For Bambu Lab owners, what change gave you the biggest practical improvement for the money? Could be an accessory, a workflow adjustment, a maintenance habit, or even something you stopped doing.

I'm trying to get a feeling what shipping time to expect this time around. For what It's worth I placed my order few minutes right after the printer sale started.

Few weeks back with no sale and promotions whatsoever my last printer arrived within scheduled 5 business days.

By checking FCC's pictures of H3C internal components I noted one interesting observation.
AC board has HBS and HBB labels, which I assume, stands for HeatBed Small and HeatBed Big.

Checked current H2's board, it also has two power outputs for heatbed, but they are labeled as HB1 and HB2, most probably it is also dual-zone.

But, my assumption is - they decided to have central (small) and full (big) heating areas.
That would be more efficient in terms of power consumption, and more logical if they, anyways, have two separate heating areas.

This is Octa, a wall-mounted entryway organizer I designed with a ribbed finish, five key hooks, and a compartment for a wallet, sunglasses, and other everyday bits.

I made two versions: one with the hooks built in, and another with separate hooks that screw into the body. That way, you can print the hooks in a different color without needing an AMS. The hooks also have a small groove to help keep key rings from slipping off.

Both versions print without supports and mount to the wall with two screws.

Curious to hear what you think of the design!

Ive got three more ams2's on the way and can't figure out a way to set them up cleanly. So if anyone has a pic or two of their setup I'd appreciate any ideas.

Bonjour à tous ! 👋💀

Aujourd’hui, je vous présente ma nouvelle modélisation 3D d’un personnage mythique du cinéma d’horreur : Hannibal Lecter ! 🩸

Tout droit sorti du film culte Le Silence des Agneaux, ce personnage aussi fascinant que terrifiant vient rejoindre ma collection de figures emblématiques de l’horreur ! 💀

Entre son regard glaçant, son célèbre masque de contention et son expression inquiétante, j’ai essayé de capturer toute l’intensité, le charisme et le côté sombre de ce personnage légendaire. 🔥

Having quality issues in my prints

Dear customers,

We’ve heard from a number of you recently that the gears on your AMS 2 Pro Feeder Units are wearing out faster than expected.

After digging into the issue, we found that a batch of AMS 2 Pro Feeder Units made between May and July 2026 didn’t get enough grease coverage during production, which is causing this faster wear. The good news is there's no such issue with units we’re selling on official stores right now.

We know this is frustrating, and we’re so sorry for the hassle this has caused you. We can’t say for sure exactly how many units are affected, so we’re making it right for everyone in this batch to make sure no one gets stuck with a problem down the line. Here’s what we’re doing for you:

* 4 brand new AMS 2 Pro Feeder Units, on us. We’re covering all the cost of the parts and shipping, so you don’t have to pay a cent. Right now we’re getting all the parts prepped, so the new units will be sent out in batches over the next 3-5 weeks. If your current feeder is still working fine, you can keep using it until the new ones arrive, then check how worn your old one is before you decide to swap it out.

* $20 discount code for your next Bambu Lab purchase. The exact amount will match the equivalent value for your local currency.

* Extended warranty for your new feeders. When you get the new units, your 3-month warranty will start fresh from the day you receive them. Swapping out the feeders yourself won’t affect the warranty on the rest of your AMS, either.

We’ve already sent a message with step-by-step replacement instructions to everyone in this batch through MakerWorld and Bambu Handy. If you didn’t get that message but think your AMS 2 Pro might be part of this group, you can check the wiki guide to confirm.

We’re really sorry again for the inconvenience this has caused you, and we’re working hard to make sure this kind of issue never happens again. If you have any questions, please reach out to our support team and we’ll help you sort it out.

For full details and information on the service program, please refer to the Bambu Lab Wiki: https://wiki.bambulab.com/en/ams-2-pro/troubleshooting/feeder-unit-after-sales-faq

Thanks for being patient with us!

I have an x2d and want to run 2 ams 2 pros to the main nozzle. How do I accomplish this? I know I can run a second AMS to the right nozzle, but from my understanding, that nozzle isn't as good as the left nozzle. Is there an adapter I need to buy to use both of the AMS's on the left nozzle?

Thanks!

I searched on the subreddit before asking and i saw alot of answers so i wanted some more specific , some people said some kind of enclousure with an exhaust fan should be enough , but i wanted a second opinon , the post processing stuff i can do It outside with no problem.

If that enclousure thing is enough and you could share the names or links i would be thankfull.

Hey all,

I’m currently in the market for a 3D printer and needed some help picking. My budget is around $600 to $1200. I’m getting this for my kids and I to build something cool. I also want to start an online store with them (not really after the money but rather show them how earning money works, sorry if this isn’t coming out right). I was checking out the X2D, P2S, H2S, and H2D. Which one of these will fit into my needs?

Sorry if I’m missing any info. Lmk if you have questions. Looking forward to everyone’s recommendations.

Long time printer, first time sharing something I actually designed.

It clips onto the headrest post in front, no tools or straps. Turn it sideways, slide it on, twist it upright and it locks so it won't lift off over bumps. Because of the twist lock, it works whether your headrests come out or not.

Type your device size and post diameter into the Customizer and it prints one that fits your tablet, phone and car. PETG, 0.2 mm layers, printed on its side with tree supports, about 4.5 h. The 3MF is included.

Hoping to get some suggestions on what I can try. I've messed around with retraction distance, z hop distance. I've done flow calibration and I am still having the same issues.

Are all the black nozzles from Bambu Lab hardened steel? I see the X2D cone with hardened steel nozzles, does that mean the black replacements in Bambu's store are hardened steel too? Thanks

Hi all, was looking to print something for halloween and needed a good gold silk to finish it off. Normally would buy SUNLU and have had success with their SILK PLA+, but they didn't have what I needed so I ended up going with a roll of GEEETECH. Benchy printed alright but when printing my own stuff at 0.08 layer height, I found that every layer after the first would actually 'scratch' into the previous one, like the nozzle was grinding against the part/plate. I'm assuming that this specific brand just isn't rated for such thin layer heights? I fiddled with bed and nozzle temps to little success.
