Bambu Lab A1 Combo vs Creality SPARKX i8: Four Colors at $399, Two Ways to Feed Them
Published · Comparison, not sponsored, specs from manufacturer data
Snapshot: prices and campaign terms as of September 26, 2026; the i8 is a crowdfunding pre-order and nothing about it is independently tested yet

Short version
Creality put the SPARKX i8 on Indiegogo on September 21, 2026 with one machine in its sights: the Bambu Lab A1 Combo. Same class of open bedslinger, same 300°C hotend and 100°C bed, same 500 mm/s, and a suggested price of $399, which is exactly what the A1 Combo sells for in Bambu's US store today. The difference is how four colors reach the nozzle. The A1 feeds four spools through the AMS Lite into one shared tube and purges on every change. The i8 runs four channels into one toolhead and claims a shared path under 1 mm, a switch in under a second and no purge tower. If the claims hold, that is the AMS Lite's weak spot fixed at the same price. Nothing has been independently tested, delivery is estimated for November, and an Indiegogo pledge is not a store purchase. For most people the A1 Combo is still the printer to buy today. The i8 is the one to watch.
Why this comparison exists now
Creality's launch release does not name Bambu, but it does not need to. Every headline number is framed against "printers with an external feed system", which is the AMS family in everything but name, and the MSRP lands on the A1 Combo's price to the dollar. The campaign runs until October 31: a limited super early bird at $289, an early bird at $309, and $399 once those are gone. Shipping is scheduled for October with delivery "expected in November".
This is not a newcomer taking a swing. The i8's smaller sibling, the SparkX i7, is a shipping product and currently Tom's Hardware's best-3D-printer pick for beginners. So the question is worth taking seriously: has the cheapest multicolor Bambu just been out-engineered at its own price, or is this a claim sheet waiting for a test?

Two ways to feed four colors
Bambu A1 Combo: one nozzle, four spools, purge on change
The AMS Lite is a four-spool feeder that sits next to the printer. Its four outputs merge into a single PTFE tube that runs to the toolhead, and that tube plus the hotend is the shared path. On every color change the A1 retracts the current filament, unloads it back through the tube, loads the next spool, and then extrudes until the old color has cleared the nozzle. That last step is the purge, the "poop" every AMS owner knows. Bambu's wiki documents flush volumes per color pair rather than promising a fixed amount, because a dark-to-light change needs more than the reverse.
Everything else about the A1 Combo is the reason it is the most recommended entry printer on this site: automatic calibration that actually works, RFID spool recognition for Bambu filament, quick-swap nozzles from 0.2 to 0.8 mm, and MakerWorld's library of painted multicolor models that slice with one click.
SPARKX i8: four channels into one toolhead, no purge tower (claim)
Creality's QuarTeks toolhead takes all four filament channels to the hotend instead of merging them in a feeder. The company says the shared section of the path is "less than 1 mm, or approximately 2 mm³", which it calls "at least 30 times shorter than other shared paths widely used in the market". If the shared volume is that small, there is almost nothing of the old color left to push out, which is why Creality claims "0 g" of external purge waste during a print and no purge tower. The fine print in Creality's own release: "Only a small amount of filament is flushed at the start."
Two things follow from the design. First, the four spools mount on the printer frame rather than in a separate unit, which is why the i8 weighs 1.4 kg more than the A1 despite the same footprint class. Second, the "CMYK full-color printing" in the release is layered mixing of four base filaments, which Creality quantifies as "16 or even 32 color combinations in a single print". That is a slicer feature stacking thin layers of different colors, not ink-style blending, and no independent print of it exists yet.
What Creality claims, and what the claims are measured against
The numbers in the launch material are precise, which makes it worth noting what each one is compared to.
- "500% faster" multicolor printing. Measured on a four-color tower needing 3,000 color switches, which the i8 finished "in about 18 hours", against unnamed "printers with an external feed system". No reference time for the other printer is given.
- "2.7x less filament waste." The comparison baseline is not stated in the release or on the product page.
- "0 g external purge waste." During printing. Creality itself notes the flush at the start of a job, and 3,000 switches with zero waste is the kind of claim that needs a scale next to the printer.
- "Under 1 second" channel switch. Plausible for the mechanism as described, but the time that matters to a print is the whole change including any wipe, and that has not been shown.
None of this means the claims are wrong. The mechanism is sound on paper, and the reason the AMS purges is precisely the length of the shared path. It means that today the entire case for the i8 rests on Creality's own measurements, and the Indiegogo page is a sales page.
Where the i8 wins on paper
- Waste and time on color-heavy prints. If the shared path really is under 1 mm, the purge problem the AMS Lite cannot fix by firmware is designed out. The more changes per layer, the bigger the gap.
- Price during the campaign. $289 or $309 against $399 for the same class of machine, and the MSRP only matches the A1 Combo, it does not exceed it.
- Camera and monitoring. A 720p feed at up to 30 fps with a light and AI failure detection, against the A1's low-frame-rate camera.
- Noise and leveling, marginally. 45 dB against Bambu's "under 48 dB", 81-point leveling against Bambu's nozzle probing. Neither is a reason to choose.
Where the A1 Combo holds up
- You can buy one. In stock, retail purchase, return rights, and it prints this week. The i8 is a pledge with a November estimate.
- Everything except the feed is a draw. Bed 100°C, hotend 300°C, 500 mm/s, 10,000 mm/s², open frame, 256 mm class. Creality matched the A1 spec for spec, so the i8's entire advantage is the feed system.
- Ecosystem. Bambu Studio, the Handy app and MakerWorld's one-click multicolor models are the reason multicolor on an A1 takes minutes to set up. Creality Print 7 and Creality Cloud exist, but nobody buys an i8 for them.
- Three years of known behavior. The A1 has been reviewed, torn down, recalled once for its bed cable and fixed, and printed in hundreds of thousands of homes since 2023. The QuarTeks head has not been printed on by anyone outside Creality.
- Upgrade path. The A1 also drives the AMS 2 Pro via OTA update, and RFID spool recognition removes a setup step the i8 does not offer.
A pledge is not a purchase
Indiegogo's own backer guidelines put it plainly: "Indiegogo is not a store. By making a Pledge, you are supporting a Project, not purchasing a product. Crowdfunding carries certain risks, including the risk that you may not receive a Reward, even if the Project is successfully funded." Creality is an established manufacturer with a shipping sibling model, so the realistic risk here is schedule rather than existence, but a November estimate is an estimate. The first 1,000 backers in the campaign's first 24 hours were promised shipping and taxes refunded up to $50, which tells you how much of the early-bird math depends on timing.

Bambu A1 Combo, for now
If you want a multicolor printer this month, or MakerWorld is part of why you want a Bambu, buy the A1 Combo. If purge waste is the thing you hate about the AMS Lite and you can wait until November on a campaign pledge, the i8 is the most interesting challenger at this price since the Snapmaker U1, and at $289 it is a cheaper bet than the U1 ever was. Wait for the first independent prints before paying the $399 MSRP; at that price the A1 Combo is the known quantity.
The bottom line
Creality did not build a cheaper A1, it built an A1 with a different feed system and priced it identically. That is a sharper attack than a discount, because it targets the one complaint every AMS Lite owner has. Whether it lands depends entirely on numbers nobody outside Creality has produced yet. We will update this comparison when the first independent tests appear and again when units reach backers.
For the wider picture on purge-free multicolor, from the Snapmaker U1's toolchanger to Prusa's INDX and Bambu's own H2C Vortek, the i8 adds a third approach at the lowest price yet: not swapping tools, not swapping hotends, but shortening the shared path until there is nothing left to purge.
