Many of you are familiar with a common pain point of single‑nozzle multi‑material systems: every colour change forces the nozzle to purge large volumes of molten plastic. These purges end up as small blobs of discarded filament, often nicknamed poop waste. Ahead of the upcoming Formnext Asia 2026 trade show in Shenzhen, manufacturer AxiLoop has unveiled a radical solution: the AxiLoop MC8, equipped with no fewer than eight independent toolheads. In this article, we take a look at what this new multi‑tool‑head 3D printer promises — and why its specification sheet strongly reminds us of another Kickstarter project.
An End to Purge‑Waste Piles? Eight Printheads Against Purge Losses
The core operating principle of the MC8 differs fundamentally from single‑nozzle colour‑switching systems such as Bambu Lab’s AMS or Creality’s CFS. Instead of feeding eight different filaments sequentially through one single hotend and performing time‑consuming purges before every colour swap, the MC8 houses eight standalone toolheads parked inside the printer frame.
Each printhead stays permanently connected to its own filament spool. The system automatically handles loading and unloading for all eight spools via guide tubes. AxiLoop makes bold marketing claims: it promises ten‑times less material waste and ten‑times higher efficiency. Real‑world independent testing will be required to verify these figures. Physically speaking, however, separate dedicated printheads do eliminate the bulk of the annoying purge‑generated waste.
Toolchanger vs. AMS‑style colour‑switching
Why do not all manufacturers adopt multiple printheads? While tool‑changing architectures like those on the Prusa XL or the AxiLoop MC8 save substantial print time and cut filament waste, they bring significantly higher mechanical complexity. Every toolhead needs precise millimetre‑level calibration for X, Y and Z offsets, otherwise visible layer steps will appear on finished prints. This will be the key test for how mature AxiLoop’s mechanical implementation really is. Affordable‑market models including the Snapmaker U1 and Flashforge Creator 5 (Pro) have already proven that at least four‑tool‑head systems can operate reliably for end‑users.
So far, AxiLoop has released little more than teaser render images for the MC8.
AxiLoop MC8: Strong Parallels to the InfiMech MX Pro
Beyond its eight printheads, the spec sheet looks competitive. With a 300 × 300 × 300 mm build volume and print speeds up to 600 mm/s, the machine aims for high‑end performance. Its fully‑automatic bed levelling uses an impressive 2500 measurement points.
But here is a notable coincidence: an eight‑tool‑changer with exactly a 300 × 300 × 300 mm build volume. Back in May, we covered the upcoming Kickstarter project InfiMech MX Pro, whose core specifications looked strikingly similar.
That said, InfiMech has already published detailed feature information: smart blob detection, active build‑chamber heating, and most notably, wireless inductively‑heated printheads (Remote‑Field Heating). AxiLoop has said absolutely nothing publicly about these critical hardware components.
Assessment: Promising Concept With Open Questions
The idea of delivering multi‑colour printing via eight separate printheads resonates strongly within the 3D‑printing community. Time savings and waste reduction compared to AMS‑type systems are undeniable advantages.
Still, since we are only seeing early teasers, we need to stay realistic. Will AxiLoop implement inductive heating for its printheads like InfiMech? Does it include active chamber heating? Most importantly: what will be its final retail price? We look forward to watching live printing demonstrations at Formnext Asia at the end of August — render images always make everything look perfect.
What is your take on this trend? Does multi‑tool‑changer hardware represent the future of FDM multi‑colour printing? Feel free to share your thoughts in the comments.
