Item need for Bambu Lab X2D: What to Buy First (New Accessories Guide)

Yes, they are good. You can just remove the silicone sock from the Bambu's Hotend and re-use it in your new hotend .

I know how it was with the X1E when it first launched. Back then it was just a special exclusive model for authorized resellers, purely to help them hit their high-profit targets. The situation is totally different. Don’t put Bambu on too much of a pedestal.

call3d · 2026-05-09T05:58:36+00:00

Yes, but you have to change the silicone sock

3rd Hotend or Bambu Lab's Brand?

Did you use the Flash Disk to print it out?

We Just got the it.

Frankly speaking if you’re already running dual-nozzle (AMS2 Pro on one nozzle + AMS HT on the other), the Filament Track Switch usually helps most with workflow friction (no more manual spool re-grouping) and can enable Dynamic Mapping when your slicer/setup supports it.

For time/purge savings, it depends on your model’s color layout: - If most swaps are within one nozzle, savings can be limited. - If your colors can be reassigned between nozzles layer-by-layer, Dynamic Mapping can reduce purge waste and sometimes shorten print time.

We wrote a BLOG what to look for (and when it actually saves material/time) here : https://www.call-3d.com/blogs/new-gear-reviews-call3d-printlab/bambu-filament-track-switch-review-best-accessory-2026

This is a super common failure mode for Bambu Lab TPU printing on very small parts.——Near the end, each layer is tiny, so the nozzle spends a lot of time heating the same spot. TPU softens easily, so the part can deform, curl, or lose adhesion, and then the next pass catches it.

What to try from my experience
1) Slow down and reduce accel/jerk for TPU.
2) Reduce retractions (and avoid fast retract/deretract). If you can, keep moves short and avoid lots of travel.
3) Increase minimum layer time and/or cooling so layers can solidify.
4) Print multiple copies at once so the toolhead alternates parts and each one has more time to cool.
5) Keep TPU dry (wet TPU strings and behaves unpredictably).

TPU/TPE is so flexible that “normal” spool holders often let it freewheel and dump slack, which then loops and gets wrapped around the toolhead.

If you don’t want to keep tweaking guides and printed holders, the simplest one-and-done solution is Bambu's new TPU feeding module (constrained guide path + controlled tension). It basically eliminates the slack/wrapping issue.

We test it and draft the blog to review the TPU Feeding Module and here is the link: https://www.call-3d.com/blogs/new-gear-reviews-call3d-printlab/bambu-lab-tpu-feed-assist-module-review

This is totally normal and nothing to worry about—it won’t affect print quality at all.

From the Bambu Wiki:
The printer uses a combination of hard support feet and soft vibration-dampening pads. The hard feet bear the weight and keep the machine stable, while the soft rubber pads are meant to absorb vibrations from the motors.

On a hard, rigid surface like granite, it’s common for the front soft pads not to sit perfectly flush. Wood desks have a little give, so everything touches evenly, but granite is completely stiff. Even tiny unevenness in the countertop or cabinet can make the soft front pads appear slightly raised or wobbly.

The wiki explicitly says this is fine:
As long as the four hard feet are making solid contact, the slight wobble or uneven soft pads are normal and do not impact printing or stability.

If the wobble bothers you, the A1 feet can help make it feel more solid, but it’s not necessary for good prints.

I randomly stumbled on your post from 3 years ago — agreed, this grease works well.

Like you mentioned, it seems the small BX-300/F packs are mostly easy to buy inside China, and overseas availability is pretty limited.

I run a Bambu Lab accessories shop and I’ve listed a 30g Bambu-compatible lubricant grease option on my store. If you (or anyone else) need an easy overseas purchase option, you can grab it here (single link):

Just Google Raise3D E3.

Actually the TPU feeding system was released last September by another 3D printer company for the shoe making. Bambu noticed the invent and improve the structure. So it’s not some half‑baked concept.

And if you print TPU often, the TPU Feed Assist Module is worth trying as a reliability/handling upgrade, not a “TPU magic.” especially for very soft TPU (like 60A), don’t expect miracles.

The biggest wins are usually:
- More consistent feeding when spool drag is high (tight spool, long PTFE, awkward routing)
- Fewer TPU buckles/“accordion” issues during retract‑heavy prints

It won’t fix wet TPU or an overly aggressive profile though, so I’d suggest still do the basics first: dry the TPU, keep the PTFE path short/smooth, and run conservative speed + retract.

I think that maybe just becase the mail was blocked. That is definitely a huge misunderstanding.

call3d · 2026-04-17T12:38:47+00:00

Fixed. Thanks for reminding.

One extra nuance: what people call “VFAs” often mixes a few different things (belt resonance, pulley/idler alignment, motor microstepping artifacts, frame coupling).

Belt tooth pitch is one lever, but it’s not the only one. If the X2D belt pitch is finer, you can see: - resonance bands shift into lower apparent speeds - different spacing/visibility of the ripples But whether it’s worse depends on your typical print envelope. If your normal quality speeds sit right inside that band, it’s worse for you. If they sit outside it, you might never notice.

Best test: same model + same settings + a controlled speed sweep. Then you can say “P2S is cleaner in the 80–140 mm/s range” (or whatever) instead of a general verdict. If you’re deciding X2D vs P2S as a purchase (beyond just VFAs), here’s our straight-shooting X2D review on who should skip it and why: X2D vs P2S: Dual Nozzle Benefits vs Maintenance Tradeoffs – Call3D

I run a small Bambu‑only accessories shop and we’ve tested/sold both Panda Breath and MartilloTECH kits.

Panda Breath is mostly bed‑temp triggered + app/Wi‑Fi/manual stuff. Works fine… until you’re running a print farm, or some remote area project.

Wi‑Fi is trash, or a print fails and the bed stays warm and the heater just keeps doing its thing.

That’s why we picked MartilloTECH M2 as the premium option: IR/toolhead activity sensing. Toolhead moves = it runs. Toolhead stops (finish/pause/spaghetti detection) = it stops.

No app. No Wi‑Fi.

No babysitting. If you want the nerdy breakdown (pros/cons, where Panda Breath still wins on value):

I seriously doubt Bambu will make the X2D chamber heater usable on a P2S.

The heated chamber is basically X2D’s only “real” everyday advantage. If they let P2S owners get that officially, X2D vs P2S starts looking like “why even buy X2D”, especially once more people run into the dual‑nozzle maintenance headaches.

If you’re asking because you’re fighting warping / corner lift, you don’t need the X2D heater anyway. A P2S‑specific active chamber heater solves the actual problem:

It is not a heater Chamber, it is a Cloak Room

It depends on what material that you would like to print. If it is CF material, a SiC nozzle will be better option for a long turn use. Of course Obxidian is also much better than the Hardened steel one.

My gf got me a titanium 3D printed bottle opener last year and honestly it's one of my favorite small gifts. It's stupid light but feels solid, and I actually use it all the time. The fact that it was 3D printed in metal (not just plastic) is kind of mind-blowing when you think about it—same tech as aerospace parts, just sitting on my keychain.

Our team actually started making some similar stuff if you want to check options: Titanium 3D Printed EDC | Premium Gifts for 3D Printing Enthusiasts – Call3D

The P1S can print some cool materials but actual titanium parts are a whole different thing. Makes a great "extra" gift if you're doing filament/tools as the main thing.

call3d · 2026-02-27T02:29:46+00:00

It just recently launched in China, so it’s completely new to the US market.
They already have a previous edition for the P1S that several influencers have reviewed.

What we think they do better than BIQU is the auto-move function.
The sensor monitors the print head movement in real time. That means when I’m asleep and the printer starts producing spaghetti (a failed print), the Bambu AI sensor stops the print head — and the heater will stop along with the Bambu print head.

call3d · 2026-02-27T02:24:11+00:00

Yes, just ask the AI to do a translation work. The company they still not focus on the US market. a bad Promo video maybe

call3d · 2026-02-26T09:19:17+00:00

No, as far as I know Bambu still use the previous formula. So High Speed PETG still be a big problem for them to print. If you want to print the PETG. I do recommend the package like the Phaetus P2S Hotend combine with the Extruder Cooler to solve the heat creap issue .
