Two different tools from Bambu Lab
Bambu Lab P2S vs H3C
My P2S makes the jigs, brackets and organizers I need around the workshop. The H3C is built around a different kind of job: changing between loaded PrintTools, handling soft filament and making larger parts in a heated chamber. They share a brand, but the work you want to make gives each one a different purpose.
Choose the P2S Combo for everyday parts that fit its 256 mm cube. Consider H3C for frequent material changes, soft TPU, or larger parts needing 65°C chamber heat. H3C supplies eight 1.75 mm tools and one 2.85 mm flexible-filament tool. I own the P2S; we have not tested H3C. [1][2][8]
My current read
I would buy them for different jobs.
I would keep the P2S Combo for the single-material jigs, brackets and organizers I make most often. The AMS 2 Pro routine is useful in my workshop: dry filament overnight, then print from the same enclosed unit. H3C’s tool system does not add much to a part that never changes material.
I would consider H3C for repeated material changes, soft TPU work, a part too large for the P2S bed, or materials that call for active chamber heat. Those are capability reasons to investigate it, not results from our own H3C testing. The supplied tools, required extra nozzle sizes and working clearance should all be part of the purchase decision.
What changes during a print
Filament changes versus separate PrintTools


PrintTools in the H3C box
8 for 1.75 mm filament, plus 1 for 2.85 mm flexible filament. All supplied nozzles are 0.4 mm. [1]
In the P2S Combo, AMS 2 Pro supplies filament to one installed hotend. Changing materials can require clearing the previous material from that shared melt path. H3C parks separate PrintTools with their material still loaded and preheats the next tool before a change. [3][8][11]
That changes the process; it does not establish a universal saving. Bambu’s switching and low-purge figures come from its own tests. We have not timed or weighed the same model on both machines. Compatible external AMS units connect through an optional Buffer to PrintTool No. 1; their filaments share that melt path. AMS lite is excluded, and 24 expanded colors do not mean 24 independently heated tools. [1][3][4]
Included hardware
Eight standard-filament tools and one flexible-filament tool
The H3C Combo supplies 8 PrintTools for 1.75 mm filament and 1 for 2.85 mm flexible filament. All supplied nozzles are 0.4 mm. Bambu specifies another 1.75 mm PrintTool for nine-color printing with 1.75 mm filament. [1]
The 2.85 mm tool is a different feed path, not another generic PLA position. Bambu currently lists Bambu TPU 75A and Generic TPU presets for that diameter. Its base and hotend are not interchangeable with the 1.75 mm version. If soft TPU is why you are shopping, check the exact filament and preset you intend to use. [1]
P2S is not excluded from TPU printing as a category. Bambu distinguishes named TPU for AMS from generic TPU and TPU 95A in the standard AMS 2 Pro path. A printer’s material list and its automatic feed-system compatibility are different checks. [11]
Inside my P2S
Build area and temperature limits
More room and active chamber heat
H3C working space · mm, W × D × H
Allow room to open the door and lid, cool the machine and reach it for maintenance. [1]
H3C lists 330 × 320 × 325 mm, a 350°C nozzle maximum and active chamber heat up to 65°C. Its 34.32 L nominal rectangular envelope is 104.6% larger than P2S’s 16.78 L cube. Liters = width × depth × height ÷ 1,000,000. P2S has a 300°C nozzle maximum and no active chamber heater. These are specifications, not a print-quality score. [1][8][10]
For a single-color bracket that fits either printer, extra tools and chamber heat may go unused. For a 280 × 280 mm base intended to print flat, the H3C bed offers room the P2S bed does not. Check brims, prime towers and other tool-clearance needs before relying on nominal dimensions. [1][8]
Bambu recommends 593 × 1,056 × 1,306 mm of working space for the standard H3C Combo, measured width × depth × height. The assembled Combo is 1,016 mm tall. Allow for opening the door and lid, cooling and maintenance; measure the working space rather than just the case footprint. [1]

$1,850 more for the listed H3C Combo $2,499 − $649. This is the named-bundle price gap, not a complete expanded-system total or a measured saving.
Prices, included equipment and shipping can change. Check the selected configuration and checkout terms.
Both Bambu store links are direct and unpaid.
H2C and H3C
How H2C differs from H3C
H2C uses one fixed left nozzle plus six interchangeable right-side Vortek hotends. H3C changes complete heated PrintTools with filament still loaded. The H2C AMS Combo includes one AMS 2 Pro and mixed-size hotends; full advertised seven-material Vortek operation requires matching hotends and appropriate feed hardware. [3][6]
On November 4, 2026, Bambu listed H2C AMS Combo at $1,899, $600 below H3C Combo. The bundles contain different hardware. H2C mixed-nozzle diameters remain a software roadmap item; its estimated dates are not delivered functionality. The existing H3C guide compares their tools, usable build areas and configurations. [1][6][7]
Choose by the job
Which printer fits your work?
Use these as shortlist rules, then verify the exact bundle, material, and current software before ordering.
Choose P2S if
Your work is mostly one material.
Choose P2S when your fixtures, brackets and organizers fit its 256 mm cube and you value the AMS 2 Pro routine. That is the setup I own; extra H3C tools may sit unused on those jobs.
Consider H3C if
The part needs separate materials or a larger heated space.
Shortlist H3C for repeated material changes, soft TPU, larger geometry or active chamber heat. Check the eight-plus-one supplied tool mix, two drying positions and required working clearance.
Wait for evidence if
You need a measured winner.
Wait for matched models, materials, profiles and measured results. Manufacturer switching demonstrations and my P2S owner impressions do not prove which printer is quieter, more reliable or cheaper per finished part.
Still choosing? Keep the next project, setup space and complete bundle in view.

What still needs checking
What we have not tested
- Price any additional 1.75 mm PrintTool, other nozzle sizes, craft tools, Buffer, external AMS or Station separately. The two named Combo prices are not a complete expanded-system total.
- Verify original Bambu hotends and Bambu Studio 2.9.1.70 or later for mixed nozzle diameters; the supplied nozzles are all 0.4 mm.
- Measure the recommended 593 × 1,056 × 1,306 mm working space and plan which spools need the two active drying positions.
- We have not run matched P2S/H3C tests for print time, waste, noise, accuracy, drying performance, reliability, maintenance or recovery.
Questions that change the decision
P2S vs H3C FAQ
These answers match the visible evidence table and keep manufacturer silence separate from a confirmed “No.”
Should I replace a P2S with H3C?
Consider H3C when frequent material changes, soft TPU, a larger build area or active chamber heat solve a problem in your work. For mostly single-material parts that fit the P2S, I would keep the less expensive setup I use in my workshop. We have not tested H3C, so this is a capability comparison rather than a matched performance verdict.
Does H3C include nine tools for 1.75 mm filament?
No. The supplied mix is eight tools for 1.75 mm filament and one for 2.85 mm flexible filament, all with 0.4 mm nozzles. Bambu says nine-color 1.75 mm printing requires another 1.75 mm PrintTool. The supplied 2.85 mm tool is for flexible filament and is installed in slot 8.
Can H3C use different nozzle diameters in one print?
Bambu documents that capability with original Bambu hotends and Bambu Studio 2.9.1.70 or later. The included nozzles are all 0.4 mm, so other sizes must be purchased separately. We have not tested mixed-nozzle printing on H3C.
Can AMS 3H dry all nine spools while printing?
No. AMS 3H actively dries two positions at a time. Its stated 85°C maximum is measured at the built-in sensor. Drying while printing is limited to suitable filament types that remain dimensionally stable at the chosen drying temperature. Follow the filament maker’s drying instructions; nine feed positions do not mean nine heated drying positions.
Can I reuse an existing AMS with H3C?
Bambu supports compatible external AMS units through an optional Buffer connected to PrintTool No. 1; AMS lite is excluded. Up to four external AMS units can expand the system to a stated maximum of 24 colors, but their filaments all share that PrintTool. That does not create 24 independent heated tools.
How much room does the H3C Combo need?
Bambu lists the assembled printer and AMS 3H at 493 × 571 × 1016 mm and recommends at least 593 × 1,056 × 1,306 mm of working space, measured width × depth × height. That allows room to open the door and lid, cool the machine and perform maintenance. Check the operating space, not just the case footprint.
Can H3C print, cut and draw in one job?
Not currently. Bambu says 3D printing and 2D craft work use separate software environments and cannot yet be combined into a single job. Craft tools and required accessories are separate purchases. Moving between the workflows also requires the appropriate plate and a separate job.
Have you tested P2S and H3C side by side?
No. I own the P2S Combo and publish my workshop photographs and observations in its owner review. H3C coverage comes from Bambu’s documentation. We have not run matched tests of print time, waste, noise, dimensional accuracy, drying performance or reliability, and we do not assign H3C a hands-on review score.
