Bambu Lab X2D Review: Not the No-Brainer Upgrade I Thought It Was

Bambu Lab X2D Review: A Powerful 3D Printer That Rewards Learning

When Bambu Lab announced the X2D, my first reaction was simple: if you're buying an enclosed Bambu printer, this is the one to get.

On paper, the X2D looked like an obvious upgrade. It offers dual nozzles, a heated chamber, improved filtration, reduced material waste, and support for advanced engineering materials—all for a relatively modest increase in price.

After spending several weeks putting the printer through real-world testing, I still believe the X2D is an excellent machine.

What changed is my understanding of who it's actually designed for.

This isn't a printer that automatically makes every other Bambu model obsolete. Instead, it's a printer that shines when paired with a user who wants to experiment, learn, and push beyond basic PLA printing.

Real-World Testing: Putting the Bambu Lab X2D to Work

Rather than spending weeks printing calibration cubes and benchmark models, I integrated the X2D directly into my existing workflow.

Over several weeks, I printed with:

• PLA

• PETG

• ASA

• PVA

• Nylon

This provided a broad overview of the printer's strengths, weaknesses, and overall capabilities.

If you're considering the X2D because you want to move beyond hobby-grade materials and start exploring engineering filaments, this is where things become interesting.

Testing the Auxiliary Nozzle and PVA Supports

One of the most exciting features of the X2D is its auxiliary nozzle.

The promise is compelling: print engineering materials with dissolvable PVA supports, place the finished part in water, and watch the supports disappear, leaving behind clean surfaces.

In practice, the experience wasn't nearly as straightforward.

The Reality of Printing with PVA

Over several weeks of testing, I encountered:

• Failed prints

• Material path clogs

• Inconsistent support interfaces

• Support structures breaking during printing

• Extensive trial and error

The original goal was to improve support removal for PETG ducting components, where traditional supports often fused to the part and damaged surface quality.

I experimented with:

• PETG supports

• PLA supports

• Full PVA supports

• PVA tree supports

The solution that ultimately worked best was using PVA as an interface layer while relying on PLA tree supports for the main structure.

Even then, achieving reliable results required extensive tuning.

Key PVA Printing Lesson

The single biggest improvement came from lowering PVA printing temperatures.

Printing PVA at approximately 220°C instead of the default 240°C significantly improved reliability and print quality.

The end result was clean, functional parts with support interfaces that were dramatically easier to remove.

However, after all that effort, one conclusion became unavoidable:

For most users, PVA printing on the X2D is not a plug-and-play experience.

Printing ASA and Nylon: Where the X2D Really Shines

While PVA proved challenging, the X2D excelled with engineering materials.

ASA Performance

The heated chamber made a substantial difference when printing ASA.

Benefits included:

• Reduced warping

• Better layer adhesion

• Improved dimensional stability

• Consistent print quality

Although ASA fumes were still noticeable, the upgraded filtration system helped improve the overall printing environment.

Most importantly, the finished parts were flawless.

Nylon Printing Experience

Nylon was one of the biggest surprises during testing.

As part of a high-speed RC car project, several stress-bearing components were printed in nylon after initial PLA prototypes validated the fit and assembly.

Despite being a first-time nylon user, the results were impressive:

• Excellent surface finish

• Strong layer bonding

• High-quality gear components

• Reliable print consistency

This is where the X2D begins to justify its premium positioning.

What I Loved About the Bambu Lab X2D

Outstanding Print Quality

The first thing that stood out was print quality.

Compared directly with the P1S, the X2D consistently delivered:

• Cleaner surfaces

• Sharper details

• Better consistency

• Improved results across multiple materials

The difference isn't dramatic, but it's definitely noticeable.

The Auxiliary Nozzle

When properly configured, the auxiliary nozzle is genuinely impressive.

Its biggest advantage is the ability to dedicate a separate nozzle to support materials, reducing contamination and making advanced multi-material workflows significantly more practical.

This opens possibilities that are difficult to achieve with traditional single-nozzle systems.

Heated Chamber

For anyone interested in engineering-grade materials, the heated chamber is a game changer.

It enables reliable printing of:

• ASA

• Nylon

• Other temperature-sensitive materials

Many of these materials would be difficult or impossible to print consistently on less capable machines.

Reduced Material Waste

One of the most practical upgrades is the reduction in purge waste.

For users printing frequent multi-material jobs, the material savings become noticeable over time.

While not revolutionary, it's a meaningful improvement.

Improved Filtration

The upgraded filtration system adds another layer of practicality for users regularly printing materials that generate fumes and odors.

It's not a replacement for proper ventilation, but it's a welcome improvement.

What I Didn't Love About the Bambu Lab X2D

PVA Isn't Beginner Friendly

The marketing around dissolvable supports can create unrealistic expectations.

The capability is absolutely there.

The simplicity is not.

Successful PVA printing requires:

• Material management

• Temperature tuning

• Workflow adjustments

• Patience

Anyone buying the X2D specifically for effortless dissolvable supports should understand there's a learning curve involved.

Bowden Extruder Limitations

The Bowden setup works well overall but introduces some compromises.

Compared with direct-drive systems:

• Flexible materials can be more challenging

• Manual filament changes are slightly less convenient

• The setup feels more industrial than refined

For most users, this won't be a deal-breaker, but it's worth noting.

Build Volume Restrictions

Although the build volume is generous, using both nozzles introduces an inaccessible strip within the build area.

For the majority of users, this won't matter, but it does reduce the practical print area slightly.

Early Firmware and Hardware Quirks

Several issues appeared during testing, including:

• Filament synchronization errors

• Communication glitches

• Firmware oddities

• AMS HT hardware issues

Most problems felt like early-adopter growing pains rather than fundamental flaws.

In one case, a faulty AMS HT unit required replacement, after which the system operated flawlessly.

Still, the overall experience felt slightly less polished than expected from Bambu Lab.

Who Should Buy the Bambu Lab X2D?

The X2D is not the best choice for everyone.

If your primary goal is printing PLA reliably with minimal effort, there are more affordable options that deliver excellent results.

However, the X2D becomes far more compelling if you:

• Want to print ASA and nylon regularly

• Plan to experiment with advanced materials

• Need multi-material capabilities

• Enjoy learning and refining workflows

• Want room to grow into more complex projects

In those scenarios, the X2D's capabilities begin to justify the investment.

Final Verdict: Is the Bambu Lab X2D Worth It?

After weeks of testing, one thing became clear:

The Bambu Lab X2D is arguably the best enclosed 3D printer currently offered by Bambu Lab.

What surprised me wasn't the hardware itself.

It was the experience.

I expected a printer that would eliminate the learning process.

Instead, I discovered a machine that rewards learning.

The more time I spent with the X2D, the more capable it became—and the more capable I became alongside it.

That's why my original opinion changed.

The X2D isn't an automatic recommendation for every user.

But for makers who want to explore engineering materials, advanced manufacturing workflows, and more ambitious projects, it's one of the most exciting printers available today.

The Bambu Lab X2D isn't just a printer that works.

It's a printer you can grow into.

Frequently Asked Questions
