Qidi Plus 5 vs Bambu X2D: Bed Size or Dual Nozzles?

Two Successors, Months Apart

Bambu ended X1 series production on March 31, 2026, and two weeks later, on April 14, shipped the X2D as the direct successor to the X1C, the printer that made enclosed fast machines the default choice for serious hobbyists. Qidi answered on August 5, 2026 with the Plus5, the replacement for the Plus 4, the machine that had become the standard recommendation for high-temperature filament on a budget. One launch in spring, one in late summer, and base prices $100 apart.

The overlap on paper is real. Both printers are fully enclosed, both heat the chamber actively to 65°C, both run the bed to 120°C, and both Combo bundles cost $899. From there the engineering budgets go in opposite directions. Bambu spent its money on a second nozzle, a mechanical switching system, and the software ecosystem around them. Qidi spent its money on a hotter hotend, a bigger build volume, and frame hardware you would expect on a machine costing hundreds more.

So the fork between them is the material you load and the parts you make. Print mostly PLA and PETG with occasional ABS, and want painless supports and multicolor along the way? That is X2D territory. Print ASA, carbon-filled nylon, or polycarbonate, or parts that will not fit on a 256mm bed? The Plus5 is built for exactly that, and nothing else at the price is.

The Specs Side by Side

Two rows deserve a closer look before the rest. The 65°C chamber line is a tie, and that is the quiet story of 2026: active chamber heating was a flagship-only feature a few years ago, and it is now table stakes at $649. Everything either machine does well with ABS and ASA traces back to that shared number, so it cancels out of the decision entirely.

What does not cancel is the hotend row and the nozzle row, and they point in opposite directions. Those two rows are the whole comparison.

What the Second Nozzle Is For

The X2D's headline feature needs precise description, because "dual nozzle" paints the wrong picture. This is not IDEX. There is no second carriage printing independently. Both nozzles ride on one toolhead: the left is the workhorse, a direct-drive extruder with a PMSM servo motor pushing 8.5 kg of force at up to 1000 mm/s, while the right is a Bowden setup capped at 200 mm/s for second-material duty. Switching between them is pure mechanics, a gear-and-trigger arrangement Bambu says has been tested through more than one million cycles, with no powered docking or wipe tower gymnastics.

For most buyers that second material will be a support filament, and this is the use case that changes week-to-week printing. Interfaces that dissolve or snap away clean, instead of pliers and knife work under overhangs, inside threads, and across top surfaces. The time penalty is smaller than people assume. TechRadar timed a two-hour print with the second nozzle in the rotation, and it finished roughly ten minutes later than the single-material version. Under ten percent slower to delete the worst chore in FDM printing is a trade most functional-part printers take every time.

The quality caveats come from Tom's Hardware's review: sidewalls laid down by the right Bowden nozzle show slight ripple that becomes visible under magnification, and TPU has to run through the left nozzle only. The working habit is to put show surfaces and flexible filament on the left and hand the right nozzle anything hidden or sacrificial. Treated that way, the second nozzle behaves like a dedicated support tool rather than a second printer, which is the honest way to describe it and the correct way to use it.

370°C and 320mm: The Plus5's Half of the Trade

The Plus5 makes the complementary bet: every number that touches the filament went up. The hotend runs to 370°C against the X2D's 300°C, which is the difference between printing and not printing the high-temperature nylon and polycarbonate grades that justify buying an enclosed machine in the first place. The build volume is 320x320x300 mm against the X2D's 256x256x260 mm, and 235.5mm on the X axis once both Bambu nozzles are in play. It is an 18 percent jump over the Plus 4's 305x305x280 mm, and parts longer than about 300mm do not fit on the Bambu at all.

Price context makes it sharper. Bambu's own route to a bigger bed in a heated-chamber machine is the H2S at $1,399. The Plus5 carries the same 65°C active chamber and a larger envelope for $749, roughly half the money. We made a version of this argument for the previous generation in our Bambu H2D vs Qidi Plus 4 comparison, and the Plus5 widens the gap. Tom's Hardware's August 12 review called it Qidi's "best one yet" and "my favorite high-temp workhorse," which is the kind of sentence that used to be written about the X1C.

The rest of the machine reads like the budget went into hardware rather than launch marketing. Linear guide rails and 9mm 1.5GT belts on the CoreXY gantry. Three-stage air filtration. A 1080p camera with AI filament recognition, a 4-inch touchscreen, 32GB of onboard storage, and USB, Wi-Fi, and Ethernet on the back, plus an RGB status light. It weighs about 64 lb, near 29 kg, so plan the bench before unboxing day.

The honest caveat is age. The Plus5 shipped in August, nobody has two years of belt and bearing wear on one, and long-term durability is unknown. On the multicolor side, Tom's Hardware's early testing found QIDI Box color changes less consistent than Bambu's AMS. Strong start, short track record.

Multicolor: AMS 2 Pro Against the QIDI Box

Both Combos cost $899, and they buy different things. The X2D Combo includes the AMS 2 Pro, the current generation of the system that defined consumer multicolor printing. Chain additional units and the X2D addresses up to 25 colors, with slicer integration and changeover logic polished by years of refinement. It is the most mature consumer multicolor setup on the market. It is also not a dryer: spools sit at room temperature unless you dry them separately.

The Plus5 Combo's QIDI Box is the opposite trade. Each box feeds four colors and chains to 16, and early tests put its color-change consistency behind the AMS. What it does that the AMS 2 Pro does not: it heats spools to 65°C while feeding them, hot enough to hold nylon and polycarbonate dry mid-print. For engineering filament, a feeder that is also a dryer in one unit is worth real money, since wet nylon ruins prints faster than any slicer setting can save them.

The decomposition is clean. Painters and multicolor hobbyists buy the X2D Combo. Engineers whose spools spend their life in the wrong humidity buy the Plus5 Combo. And if your real question is value rather than flagship, we ran the Plus5 Combo against Bambu's cheaper P2S Combo in a separate head-to-head.

Which Configuration to Buy

The ladders are not symmetric. The X2D is $649 alone or $899 with the AMS 2 Pro ($849 and £769 for the Combo in the EU and UK). The Plus5 is $749 alone, $899 with the QIDI Box, $899 as the Polar Cooler Bundle, and $1,049 as the Combo Polar Cooler Bundle. Qidi ran a $699 launch price through August 31, 2026, and it has ended. $749 is the real price, and waiting for the launch deal to come back is not a plan.

CNC Kitchen called the X2D's pricing "extremely aggressive" at launch, against a community that had penciled in around $1,000 for a dual-nozzle X1C successor. That is why this comparison is close at all. Bambu priced the X2D to hold the volume tier, and Qidi priced the Plus5 to attack the same tier from the high-temperature side.

The buying logic follows the material question, not the price tag. If you print one spool at a time, buy whichever bare machine matches your filament and skip both Combos; multicolor hardware sitting idle is $150 to $250 of somebody else's use case. If color or support filament is the point, the Combo question is the one the multicolor section above answers.

Our Pick

For most buyers the X2D is the default, and we would tell a friend to start there. Support-free printing is a quality-of-life upgrade you feel on every functional part, the 25-color AMS ecosystem and Bambu's software polish remain the category benchmark, and the $649 entry price undercuts everything with comparable capability. The dual-nozzle support workflow alone closes the case for anyone who prints brackets, enclosures, or parts with difficult geometry.

The exception is not subtle. If your spools say ASA, PA-CF, or PC, or your parts need more than 300mm in any direction, the Plus5 is the only machine at this price that can do the work. The X2D's 300°C hotend ceiling and 256mm axes are hard limits, not soft ones, and no firmware update changes them. Paying $749 for capability the X2D cannot reach is a better deal than paying $649 for a machine you will outgrow.

Two asides. If this is your first printer rather than an upgrade, both machines are more machine than a beginner needs, and our best 3D printers for beginners guide starts cheaper. If your budget debate sits one tier down instead, the Creality K2 vs Qidi Q2 comparison covers the same heated-chamber-versus-ecosystem tension for less money.

Frequently Asked Questions

Which is better overall, the Qidi Plus 5 or the Bambu X2D?

For most buyers, the Bambu X2D. Its dual nozzles make support removal near-effortless, the AMS 2 Pro ecosystem supports up to 25 colors, and the software is the most polished in the category, all at $649. The Plus5 wins instead when your work needs its hardware limits: a 370°C hotend for high-temp nylon and polycarbonate, and a 320x320x300mm bed for parts that will not fit the X2D's 256mm axes. If you cannot name a material or part size that requires the Plus5's numbers, buy the X2D.

Can the Bambu X2D print nylon or polycarbonate?

Partially. The X2D has the same 65°C actively heated chamber as the Plus5, so the warping side of the equation is handled, and standard-temperature engineering filaments like ABS and ASA are comfortable. The limit is the 300°C hotend ceiling. The high-temperature nylon and polycarbonate grades that motivated the Plus5's 370°C rating are out of reach, and TPU has further constraints, since it must run through the left nozzle only. If PA and PC are the mission, the Plus5 is the machine at this price.

Should I buy the X2D Combo or the Plus5 Combo?

Both cost $899, so decide by workflow. The X2D Combo's AMS 2 Pro offers up to 25 colors and the most refined color-change system available, but it does not dry filament. The Plus5 Combo's QIDI Box tops out at 16 colors and its changes are less consistent in early testing, but it dries spools at 65°C while feeding them, which matters enormously with nylon and PC. Multicolor and display work point to the X2D Combo. Engineering filament points to the Plus5 Combo. Single-material users should skip both and buy the bare machine.

Does the X2D's right Bowden nozzle hurt print quality?

Slightly, on surfaces it prints. Tom's Hardware observed subtle sidewall ripple from the right nozzle that becomes visible only under magnification, and the right nozzle is capped at 200 mm/s besides. In practice you assign visible surfaces to the left direct-drive nozzle and give the right one supports and hidden geometry, at which point the difference stops mattering. It is a support tool doing support work.

Is a dual-nozzle printer worth it just for support material?

If you print functional parts regularly, yes. TechRadar measured a two-hour print using both nozzles finishing about ten minutes slower than its single-material version, a small cost for support interfaces that break away or dissolve instead of being carved off with pliers. Overhangs, threads, and holes come out dimensionally cleaner because the support interface is a different material, not the model filament squeezed into a sacrificial role. If you print single-material display models, the second nozzle will sit idle, and the $649 base X2D without the fuss makes more sense.

Narrow It Down Yourself

Spec sheets this close invite second-guessing, and the fastest way out is a proper head-to-head. Paste the two printers you are torn between into Versa AI, and it reads both products' specs and review sentiment, then writes the comparison with a clear pick, so the decision rests on evidence rather than forum vibes.
