Bambu Lab X2D One-Week Review: Real Prints, Dual Tool Head, AMS, and Tradeoffs

After my first-day Bambu Lab X2D setup, I kept the printer running for a week to see whether the polished first prints would hold up across more material, small-part adhesion, multicolor work, and the two filament paths. My short answer after that week: the printer produced consistently strong results for me, and the dual-tool-head approach made a real difference on the right multicolor jobs. It is not equally useful for every color change or every flexible material.

This is a hands-on one-week review based on the prints and workflows shown in my original video. It is not a long-term durability claim, and it separates what I actually tested from general setup guidance.

Quick verdict after one week

I would buy the X2D again based on this first week. It stayed reliable through the mix of prints I ran, and I liked the flexibility of four AMS positions plus one external spool path. For someone doing frequent multicolor work, the second path can save meaningful time and material when the design repeatedly changes between two colors. For a model with just one color swap, that advantage is much smaller.

The main workflow tradeoff I found was material handling. The external spool path is Bowden-fed, while the AMS-side path is direct drive in the setup I tested. That makes the printer less appealing for users who expect the external path to be the answer for soft TPU or every specialty filament.

The first practical prints I would add

Adapter spools for smaller 250 g rolls

The first two models I made were adapters so I could use 250 g rolls with the AMS. Those smaller rolls did not fit the AMS unit directly in my setup. Both adapters came out without issues, and I chose PETG for them because I wanted better heat resistance if they later sat in a filament dryer. That choice was based on the use case rather than a universal material prescription.

Print a purge catch chute before running many multicolor jobs

The most useful accessory print from my first week was a filament purge catch chute. I initially ran a handful of multicolor prints without one and ended up with a noticeable amount of purge material on the floor. The chute was a quick print and gave the waste a predictable place to go. I would put this ahead of decorative accessories if you expect to use frequent color changes.

Print quality and small-part adhesion

Across the week I printed storage pieces, a catch-all bowl, eggs that open for storage, calibration cubes made with Bambu Studio's color-mixing feature, and a photography turntable. The turntable was intentionally useful as a test because it included many small bolts and tiny pieces where poor adhesion would be obvious. In the prints shown, I had zero adhesion issues and the small features completed cleanly.

I also printed a broad mix of models over the week rather than relying on one calibration object. I did not have a single issue with the prints I showed in this review. That is a strong first-week result, but it should not be read as a promise that a different material, model geometry, profile, or future machine will behave identically.

AMS, TPU, and the two filament paths

One compatibility lesson came from trying to load standard TPU into the AMS. The printer reported it as unsupported. In the video, I found that normal 95A TPU was too soft for that AMS workflow; Bambu TPU or a TPU specifically designed for the AMS was the safer route. I did not test standard TPU through the external spool path because I do not like running TPU through a Bowden tube.

That distinction matters because the X2D combines two approaches. The AMS-fed side uses a direct-drive system in the workflow I tested, while the external spool uses a Bowden path. Before buying material for an X2D project, confirm that the specific filament and the path you intend to use are compatible. Do not assume the external spool makes every flexible or exotic filament a good fit.

When the dual tool head saved time and filament

The most useful X2D result in my week was not simply that it could print multiple colors. It was the difference between a job that changed color every layer and one that only changed once. I printed a black-and-red color-mix example with one spool in the AMS and one on the external system. That job took about 45 minutes.

For comparison, a blue-and-white color-mix example with both spools in the AMS took about 2 hours and 45 minutes and generated much more purge waste. In those examples, the colors were switching every layer. That repeated change is where the two-path setup had a clear practical advantage. It avoided a long series of normal AMS purge cycles.

That does not mean the dual tool head is automatically worth optimizing for every two-color model. A dragon that moved from black to red only once needed one purge, so the potential savings were much smaller. If a model changes color once or twice, the extra preparation to use the alternate path may not be worth it. If it changes back and forth continually, the time and waste savings become much more compelling.

What worked well in day-to-day use

• I had no print failures in the models shown during the first week.
• The printer handled small parts and the turntable's small bolts without an adhesion problem in my test.
• The AMS plus external-spool setup gave me five available material positions: four in the AMS and one external path. A second AMS could expand that to nine positions, as discussed in the video.
• I could start and monitor a couple of prints while away from home, checking the first layer with the camera before returning to completed prints.

Limitations and who should think twice

The external Bowden path is the real compromise

My major reservation was the external spool's Bowden path. I would have preferred an all-direct-drive approach for more confidence with flexible and unusual materials. It did the job for the work I ran, but it is a design constraint to understand before choosing the machine around a specific material workflow.

The strongest value is for frequent color switching

The X2D made the most sense in my testing for designs that switched colors repeatedly. If your work is mostly single-color, or colors change only once in a long model, the dual-tool workflow will not deliver the same time and purge reduction.

It is still part of the Bambu ecosystem

I was comfortable with the Bambu ecosystem during this test and had a smooth experience. If that ecosystem is something you prefer to avoid, that is a separate purchasing concern even though the printer itself worked well for me during the week.

Who I would recommend the X2D to after this test

I would recommend it to makers who regularly run multicolor designs with many repeated switches, want a guided machine-and-slicer workflow, and are comfortable validating material compatibility before loading a new spool. It was also a good fit for my mix of small functional prints, storage pieces, and remote print monitoring.

I would pause before recommending it specifically for a TPU-heavy workflow, especially if the plan depends on the external Bowden spool path. I would also think carefully about the added system complexity if the work is mostly simple single-color prints.

Bambu Lab X2D one-week review FAQ

Did the X2D have print failures in the first week?

Not in the prints shown in my one-week review. I ran a range of utility models, small parts, multicolor examples, and test pieces without a print issue.

Can the X2D use normal 95A TPU in the AMS?

In my test, standard TPU was reported as unsupported by the AMS. I would use TPU designed for that AMS workflow or verify the current compatibility guidance for the specific material before printing.

Does the dual tool head always save filament?

No. The biggest savings in my examples came when colors switched repeatedly every layer. A model with one color transition requires far less purging, so the benefit is much smaller.

What should I print first for the X2D?

I would start with a purge catch chute if you plan to run multicolor prints, then use a simple functional model to confirm the printer, profile, and loaded materials before moving to a larger project.
