Key takeaways
- A single-nozzle multicolour printer has to purge plastic at every change. A multi-toolhead printer keeps each material in its own nozzle, so purge almost disappears — makers publish 85–90 % reductions from their own internal tests.
- Four machines, three architectures: swapping from a dock (U1, Creator 5 Pro), IDEX plus toolchanger (M1D), and four independent heads on one axis (Quadro).
- For engineering materials, the line that matters is chamber heating: Creator 5 Pro up to 65 °C, M1D Advanced up to 60 °C. The U1 only has an optional top lid; Quadro hasn't published it.
- Four to seven spools loaded at once means four to seven spools in the open for the whole print. In a humid climate, that's a material problem, not a printer problem.
- None of these four is "best" — they're designed for different jobs, and two of them haven't shipped.
2026 is the year multi-toolhead printers came down to desktop prices. Until now, multicolour printing in this segment had essentially one method: one nozzle, a multi-spool feeder, and a prime tower that swallows plastic at every colour change. This article sets side by side four machines that change that, exactly as their makers publish them — and points out where the makers haven't published yet.
Why multiple toolheads is a materials question
A single-nozzle printer changes colour by retracting the old filament, pushing the new one in, then extruding the mixed plastic until the new colour runs clean. That plastic goes into a prime tower or a waste chute. On a part with many colour changes, the purge can outweigh the part. That's filament money, and machine time.
A multi-toolhead printer keeps each material in its own nozzle, already hot. Changing colour means changing heads, not filament. Snapmaker publishes up to 85 % less waste, Co Print up to 90 % — both against single-nozzle multicolour printers, from their own tests. The real figure depends on the part, but the direction isn't in question. How to estimate the purge for your own print is in multicolour printing purge waste.
Three architectures
Each machine changes heads a different way
- Swap from a dock
- One moving carriage; the toolheads park at the side; the printer drops one and picks up another — Snapmaker U1, Flashforge Creator 5 Pro
- IDEX + toolchanger
- Two heads moving independently; the left one fixed, the right one swapping between six docked heads — Sovol M1D
- Four independent heads on one axis
- All four heads ride the X axis and move by themselves, no picking up — Co Print Quadro (which calls it IQEX)

Snapmaker U1 — a compact four-head toolchanger
The U1 swaps a whole toolhead in 5 seconds, with 270 mm in each axis, a 300 °C 0.4 mm stainless steel nozzle and a 100 °C bed on a PEI steel sheet. The maker publishes a 32 mm³/s maximum flow and 20,000 mm/s² acceleration. The material list on the product page includes PLA, PETG, TPU, PVA, ASA, PA and PAHT-CF.
Read this carefully: the U1 has no heated chamber. The separately sold Top Cover turns it into a passive enclosure — enough to hold heat for medium ASA parts, but not the condition for large PA or PC parts. And the stock nozzle is stainless steel, not hardened; if you plan to print a lot of fibre-filled material, read the nozzle article first.
Flashforge Creator 5 Pro — four heads and a heated chamber
The Creator 5 Pro has the same four-head layout and 256 mm in each axis, but raises the heat ceiling: a 320 °C nozzle, a 120 °C bed and active chamber heating up to 65 °C. The maker lists a 300 mm/s maximum print speed (600 mm/s is travel) and 30,000 mm/s² acceleration, with 0.25 / 0.4 / 0.6 / 0.8 mm nozzles.
Its published material list is the longest of the four: from PLA, PETG and TPU to ABS, ASA, PA-CF, PAHT-CF, PPA-CF and PPS-CF, plus two soluble supports, PVA and BVOH. According to Flashforge's own comparison, the standard Creator 5 has the same build volume, the same 320 °C and 120 °C, but no chamber heating — and that's exactly the deciding difference for ABS, ASA and nylon.
Sovol M1D — IDEX combined with a toolchanger
The M1D does something different: two heads running independently (IDEX), where the right one swaps between six docked heads, seven in total. Sovol calls it DualX 1+6. A head change takes 5 seconds. Build volume is 300 × 300 × 350 mm with one head, shrinking to 240 × 300 × 350 mm with all seven. A hardened steel 300 °C nozzle, a 100 °C bed, 10,000 mm/s² acceleration.
There are two versions: Essential is open-frame; Advanced adds an enclosure and active chamber heating up to 60 °C. Sovol is also the only one of the four committed to fully open hardware, firmware and software — significant for anyone who wants to repair the printer themselves; see open-source 3D printers. At the time of writing it's on pre-order, with the maker giving late November to mid-December for delivery.
Co Print Quadro — four independent heads, not yet launched
Co Print is known for multicolour upgrade kits for existing printers. The Quadro is its first printer: four independent heads on one X axis (which it calls IQEX), so changing heads needs no pick-up — about 1 second. Build volume is 300 × 300 × 300 mm on a 305 × 305 mm bed, and all four heads reach the whole bed.
The upcoming Creality K3 — beside the U1 and Creator 5 Pro
The K3 targets exactly the U1 and Creator 5 Pro's segment: four colours or materials, no purge, under $900. The difference is the method. The K3 doesn't pick up whole toolheads; it only changes nozzles, using its KliTek system: four nozzles, changed in 4.8 seconds. Creality says "Q3 2026" on the product page with pre-orders opening mid-October, so at the time of writing the printer hadn't shipped.
| Snapmaker U1 | Creator 5 Pro | Creality K3 | |
|---|---|---|---|
| How it changes | Whole toolhead (4) | Whole toolhead (4) | Nozzle only (4, KliTek) |
| Change time | 5 seconds | — | 4.8 seconds (nozzle) · 15 seconds (material) |
| Build volume | 270 × 270 × 270 mm | 256 × 256 × 256 mm | 260 × 260 × 260 mm |
| Max nozzle · bed | 300 °C · 100 °C | 320 °C · 120 °C | 300 °C · 100 °C |
| Chamber | Optional top lid | Actively heated to 65 °C | Optional top lid |
| Materials the maker lists | PLA, PETG, TPU, PVA, ASA, PA, PAHT-CF | From PLA to PA-CF, PPA-CF, PPS-CF | PLA, PETG, PET, PCTG, PLA/PETG-CF/GF, TPU 95A |
| Maker price | $849 | $849 | "expected under $900" |
| Status | On sale | On sale | Upcoming, pre-order mid-October |
Read by material: the K3 and U1 share a 300 °C / 100 °C ceiling and neither has chamber heating, so both suit PLA, PETG and TPU best. The K3's material list has no ABS or ASA; the U1's has ASA. The Creator 5 Pro is the only one of the three with active chamber heating. The K3's own trick is mixing nozzle sizes in one print — 0.4 mm for outer walls, 0.8 mm for infill — and TPU 95A out of the box. Full details in Creality K3 and SPARKX i8.
What multiple toolheads change for your filament
- Moisture. Four to seven spools loaded means four to seven spools in the open for the whole print — sometimes all day. In a humid climate, PETG, TPU and nylon absorb enough to string within that print. You need a dryer or sealed box per spool; see how to dry filament.
- Soluble supports become practical. With PVA or BVOH in their own nozzle, there's no more purging at every interface layer. The U1 lists PVA; the Creator 5 Pro lists both PVA and BVOH. See soluble supports.
- Pairing materials from different families. PLA and PETG bond poorly to each other — a weakness when joining parts, but a strength when using one as the support interface for the other. Multi-toolhead printers make that cheap.
- The chamber decides the engineering material list. More heads don't replace chamber heat. Large ABS, ASA and PA parts need a chamber that holds heat; see enclosures and chamber heating.
- Every head is a nozzle to maintain. Four stainless nozzles printing carbon fibre are four nozzles wearing together. Upgrading to hardened nozzles multiplies by the number of heads.
Multiple toolheads get rid of purged plastic. They don't get rid of wet plastic.
Other approaches the same year
Not every multicolour printer this year changes heads. Besides the K3, Creality has the SPARKX i8, which feeds four filament channels into one toolhead — see Creality K3 and SPARKX i8. The Bambu Lab X2D uses two fixed nozzles, and two new Bambu machines have so far appeared only in FCC filings — see Bambu Lab X2D Pro and H3C.
If you're choosing a first printer, a multi-toolhead machine is rarely the right starting point — see choosing your first 3D printer. If you already know which materials you need, check them against the four numbers that decide what a printer can print.
Frequently asked
What is a toolchanger?
A printer with several complete toolheads (each with its own nozzle, heater and usually extruder) that swaps the active head during the print. Each material stays in its own nozzle, so changing colour needs no purge the way a single-nozzle printer does.
Do multi-toolhead printers really save filament?
Yes — purge at colour changes almost disappears. Snapmaker publishes up to 85 % less waste and Co Print up to 90 %, both against single-nozzle multicolour printers in their own tests. The real saving depends on how often the part changes colour: a single-colour part saves nothing.
Which of the four prints ABS, ASA and nylon best?
We don't rank printers. The requirement is a chamber that holds heat: the Creator 5 Pro has active heating up to 65 °C and the M1D Advanced up to 60 °C. The U1 only has an optional top lid (a passive enclosure), and the Quadro hasn't published it. Check against the requirements of the exact material you plan to print.
How is IDEX different from a toolchanger?
IDEX has two toolheads moving independently on the same axis, able to print two copies or mirrored copies at once. A toolchanger has several docked heads and picks one up to print. The Sovol M1D combines both: one fixed head on the left, and the right head swapping between six.
Can I buy the Co Print Quadro yet?
Not at the time of writing (03/10/2026). Co Print's page only takes reservations ahead of a Kickstarter campaign, and many specs — nozzle temperature, bed temperature, enclosure — haven't been published.
Snapmaker U1 or Creality K3?
We don't rank printers. The two share a heat ceiling (300 °C nozzle, 100 °C bed), neither has chamber heating, and both do four colours without purge. The U1 swaps whole toolheads, is on sale, and lists ASA and PA. The K3 swaps nozzles and lets you mix nozzle sizes in one print, but hadn't shipped at the time of writing (Creality says Q3 2026, pre-order mid-October) and its material list has no ABS/ASA.
