Bambu Lab X2D Review: The Dual Extrusion Revolution (Now Being Tested at Smart3dpt!)

Published by Smart3dpt Team | Updated in April 2026

🚀 Exclusive News: The Smart3dpt team already has the new Bambu Lab X2D in our facilities! We are conducting intensive testing to ensure that we offer you the best support and knowledge about this revolutionary machine.

Bambu Lab X2D - Dual Extrusion 3D Printer

Introduction: The Next Step in 3D Printing

Bambu Lab has shaken up the market again with the launch of the Bambu Lab X2D. Being the second generation of the acclaimed X series, this machine promises to solve one of the biggest challenges of FDM 3D printing: support removal and multi-material printing without excessive waste.

At Smart3dpt, we couldn't let this innovation pass us by. We already have the machine on our test bench and, after analyzing the main international reviews and our own initial experience, we compiled everything you need to know about the X2D.

What Makes the Bambu Lab X2D Special?

The great innovation of the X2D is its dual extrusion system with mechanical switching. Unlike traditional systems that use two heavy motors on the X axis, the X2D combines a Direct Drive extruder (for the main material) with an auxiliary Bowden extruder (ideal for support material).

Main Technical Features

Print Volume: 256 x 256 x 260 mm (Dual Nozzle Union)
Maximum Temperature: Nozzle up to 300°C and actively heated chamber up to 65°C
Advanced Filtration: 3-stage system (G3 Pre-filter + HEPA H12 + Activated Carbon)
Dynamic Calibration: Real-time monitoring of flow and extruder status
PMSM Motor: 20,000 samples per second to prevent clogs

Pros and Cons of the Bambu Lab X2D

Based on our tests at Smart3dpt and the consensus of the expert community (such as Tom's Hardware and Thomas Sanladerer), here is our honest assessment:

✅ Strengths (Pros)

True Dual Extrusion: Almost zero waste in two-color or support prints, saving a lot of time and material compared to the traditional AMS system.
Perfect Support Removal: The ability to use dedicated interface materials (such as PVA or specific support filaments) leaves immaculate contact surfaces.
Actively Heated Chamber (65°C): Excellent for engineering materials such as ABS, ASA, and Nylon, eliminating warping problems.
Superior Air Filtration: The HEPA + Activated Carbon system makes it safe for use in offices and enclosed environments.
Competitive Price: With a base price around $649 (approx. €629), it offers industrial machine features at a consumer price.

❌ Weaknesses (Cons)

Auxiliary Nozzle Limitations: Being a Bowden system, the second nozzle is less precise, slower, and not suitable for printing flexible materials (TPU).
TPU Restrictions: The machine is limited to harder TPU ("TPU for AMS"), not handling very soft variants well.
Limited Flow Calibration: Advanced dynamic calibration only works on the main nozzle (Direct Drive).
Noise Level: Despite the improvements, it remains a noisy machine when operating at high speeds, making it not ideal for bedrooms.

What Are We Testing at Smart3dpt?

To push the Bambu Lab X2D to its limits, our technical team is conducting a battery of rigorous tests. If you are thinking about acquiring one, we recommend that you perform the same tests:

Two-Color 3D Benchy: To test speed, overhangs, and the real efficiency of dual extrusion without a purge tower.
Soluble Support Test (PVA): Printing complex geometries to validate the main advantage of the second hotend.
Engineering Parts in ABS/Nylon: Evaluation of active chamber heating and layer adhesion in large parts.
Maker's Muse Clearance Castle: To test extreme tolerances and the precision of the mechanical switching system.

Final Verdict

The Bambu Lab X2D is not just an iterative update; it is a paradigm shift in how we handle supports and multi-material prints. Although the second Bowden extruder has its limitations, the compromise achieved allows the print head to remain light and fast, resulting in exceptional surface quality.

For those who frequently print complex parts that require supports, or technical parts in ABS/ASA, the X2D is undoubtedly one of the best options on the current market.
