H3C Arrives Less Than a Year After H2C — What About Existing Flagship Owners? We Need an FTS 2.0.
As an H2C owner who has invested heavily in Bambu Lab’s ecosystem, I have mixed feelings about the H3C announcement.
The H2C was officially unveiled in November 2025. Less than a year later, Bambu Lab has introduced the H3C, featuring an entirely new tool-changing architecture.
Technological progress is welcome. I don’t expect Bambu Lab to stop developing new products.
But I do expect a company to fully support its existing flagship products before shifting the spotlight to the next generation.
The H2C remains excellent hardware, yet some of its potential is still locked behind software limitations and poorly integrated accessories.
1. The Filament Track Switch Is Too Limited
I currently use four AMS 2 Pro units and two AMS HT units with my H2C.
The current Filament Track Switch (FTS) has only two inputs. In my setup, two AMS units share one input, while the other four share the second input through filament adapters.
As a result, switching between filaments from AMS units sharing the same input still requires retracting the previous filament through the shared path.
This significantly reduces the potential time-saving benefits of the FTS.
In many situations, the FTS mainly provides the convenience of routing filaments to either nozzle rather than a substantial improvement in printing speed.
Why wasn’t the FTS designed with at least four independent inputs from the beginning?
An eight-input design would be even better.
With independent AMS inputs, users could organize frequently switched materials across different AMS units, potentially keep filaments staged near their respective switch inputs, and reduce unnecessary retraction distances.
Combined with intelligent filament-routing software, this could make a real difference in multi-material printing.
2. TPU Feed Assist and FTS Still Cannot Work Properly Together
This is even more frustrating.
Both the TPU Feed Assist and FTS are official Bambu Lab accessories. Yet users still encounter software restrictions that prevent using an external TPU feed while the FTS remains connected.
Why should customers have to physically disconnect one official accessory just to use another?
This is particularly disappointing on a premium printer designed to simplify multi-material workflows.
3. H3C Makes the Situation More Disappointing
Bambu Lab has demonstrated impressive engineering with the H3C.
Meanwhile, H2C users are still waiting for important software capabilities and proper integration of existing accessories.
While I appreciate that Bambu Lab has finally announced an estimated timeline for mixed nozzle-diameter printing, H2C owners are still expected to wait until February 2027 without the FTS, and March 2027 with the FTS.
In other words, customers who purchased an additional official accessory may have to wait an extra month for the same software capability.
Meanwhile, compatibility issues between the FTS and TPU Feed Assist remain unresolved.
The problem isn’t that H3C is better. The problem is that H2C owners still cannot fully use the hardware and accessories they have already purchased.
When a new flagship arrives before the previous flagship’s ecosystem feels complete, customers naturally question whether their investment will receive sufficient long-term support.
4. My Proposal: FTS 2.0 and a Fair Upgrade Program
I would like Bambu Lab to consider the following:
1. Fix TPU Feed Assist and FTS compatibility as a priority.
Allow external TPU feeding without physically disconnecting the FTS. These are both official accessories and should work together.
2. Develop an improved FTS 2.0 with at least four independent AMS inputs, ideally eight.
Each AMS should be independently routable to either nozzle, with smarter filament staging and switching.
This would improve the usefulness of the Vortek system and reduce filament switching times between different AMS units.
3. Offer existing FTS owners a meaningful upgrade discount or trade-in program.
Customers who invested in the original design should not have to pay full price again to overcome its limitations.
A reasonable upgrade policy would demonstrate that Bambu Lab values its existing customers.
4. Publish a clear H2C software development roadmap.
Explain which features will be improved, their expected availability, and how long the H2C ecosystem will continue to receive meaningful updates.
I’m not asking Bambu Lab to make the H2C identical to the H3C. They are different machines with different architectures.
I’m asking Bambu Lab to finish what it started.
Final Thoughts
I still believe the H2C is an excellent machine. Its Vortek system, convenient hotend changes, and material flexibility have genuine advantages.
That’s precisely why this situation is so disappointing.
Bambu Lab has earned its reputation by making powerful technology easy to use. But customer trust depends on more than impressive new product launches.
A flagship should not feel prematurely abandoned simply because a newer flagship has arrived.
An improved FTS, proper accessory integration, and a fair upgrade policy would demonstrate that Bambu Lab values its existing customers as much as its future ones.
I’d be interested to hear how other H2C owners feel about this.
Would you consider buying an FTS 2.0 with four or eight independent AMS inputs, especially if Bambu Lab offered an upgrade discount to existing FTS owners?
