Bambu Lab X2D Review: The Dual Extrusion Revolution (Already Under Test at Smart3dpt!)

Published by Smart3dpt Team | Updated April 2026

🚀 Exclusive News: The Smart3dpt team already has the new Bambu Lab X2D in our facilities! We are conducting intensive tests to ensure 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 once again shaken up the market with the launch of the Bambu Lab X2D. As the second generation of the acclaimed X series, this machine promises to solve one of the biggest challenges in 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've compiled everything you need to know about the X2D.

What Makes the Bambu Lab X2D Special?

The major 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).

Key Technical Features

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

Pros and Cons of the Bambu Lab X2D

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

✅ Strengths (Pros)

True Dual Extrusion: Almost zero waste in two-color prints or with supports, saving immense time and material compared to the traditional AMS system.
Perfect Support Removal: The ability to use dedicated interface materials (like PVA or specific support filaments) leaves immaculate contact surfaces.
Actively Heated Chamber (65°C): Excellent for engineering materials like 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 stiffer 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 improvements, it remains a noisy machine when operating at high speeds, 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 series of rigorous tests. If you are considering purchasing one, we recommend 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 inter-layer adhesion on 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's a paradigm shift in how we approach supports and multi-material printing. 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 requiring supports, or technical parts in ABS/ASA, the X2D is, without a doubt, one of the best options on the market today.
