Sovol M1D: Can This $1,199 7-Color IDEX Toolchanger Truly End Filament Waste?

Multicolor FDM printing has an expensive open secret: mountains of wasted filament. Anyone who has watched an automated system cycle through hours of purging knows the pain of essentially watching money melt onto a massive purge block.

The new Sovol M1D desktop 3D printer wants to put an end to that waste, and then some. Launching soon on Kickstarter with Sovol’s self-developed hybrid IDEX toolchanger system, the M1D promises seven-color capability with virtually zero purge waste, five-second toolhead swaps, automated calibration and monitoring, and a redesigned UI, with early bird pricing at $1,299 and VIP pricing at $1,199 with a deposit.

The Tech Behind Waste-Free Multi-Material Printing

At the center of the M1D is DualX, Sovol’s self-developed IDEX toolchanger system. While Independent Dual Extruders (IDEX) aren’t a new concept in desktop 3D printing, Sovol’s implementation is a departure from the norm.

Rather than forcing two fixed heads to compete for space on the same X-axis, the M1D pairs one fixed extruder with one tool-changing extruder, allowing each to heat completely independently. The result is a machine that can handle up to seven colors or materials in a single print run with virtually no purge waste. Because each toolhead carries its own dedicated filament, it only extrudes material that actually ends up in your final model.

That architecture unlocks four distinct print modes, each suited to a different workflow:

• Multi Mode is the headline use case, combining up to seven colors or materials, including support filaments, in a single flexible run. This is where the IDEX architecture earns its keep.
• Copy Mode runs both extruders simultaneously to produce two identical parts in the same print. For anyone creating spare parts, running small-batch production or operating a small-scale print farm operation, this effectively doubles throughput without adding a second machine.
• Mirror Mode uses the independent extruders to print left-right symmetrical parts at the same time. Paired components like handles, brackets, wings, and other symmetrical prototypes will come off the bed already matched, with consistent geometry in half the time.
• Single Mode runs one extruder for standard single-material prints when you don’t need the multi-toolhead overhead.

Five-Second Swaps: Built to Keep Moving

The DualX system’s speed is also worth noting. Its self-developed metal auto-grip mechanism swaps toolheads in just five seconds, securing each head firmly enough to maintain precision even at high print speeds.

Each toolhead preheats before it’s called into service, so there’s no idle time waiting for a nozzle to come up to temperature mid-print. Compared to single-nozzle systems that cycle through purging, cleaning, and reheating between every color change, the M1D keeps the job moving.

Smart Features That Keep Prints on Track

The M1D pairs its mechanical design with a suite of automated monitoring and calibration tools that handle the variables most likely to derail a long multicolor job.

Auto Vision Calibration uses camera feedback to adjust XY offsets between toolheads automatically, which is up to 2.5 times faster than traditional probe-based calibration. A toolhead Auto Z-Lift structure continuously adjusts the second toolhead’s Z offset in real time, keeping both heads at consistent height with the heated bed throughout the print. An eddy current sensor provides non-contact, high-precision bed measurement for automatic leveling without the wear of a physical probe.

Smart Print Monitoring through the printer’s camera watches the build plate for spaghetti-like filament tangles and foreign objects, pausing the job before a small problem becomes a wasted spool. A 6-Channel Auto Filament System integrates run-out, nozzle clog, and filament tangling detection with indicator lights for fast diagnosis, as well as supports auto-loading across all six input channels.

Users control the machine by way of a five-inch touchscreen running Sovol’s redesigned UI, which is built around a simpler tap-and-go workflow that makes managing a seven-color job feel like using a modern consumer appliance.

Open Source, Down to the Hardware

Sovol is carrying its open-source philosophy into the M1D. Much of the hardware and software are open source, with data files and drawings uploaded to GitHub. That means makers aren’t locked into a sealed box, but can instead inspect how the machine is built and DIY or modify it to fit their own requirements, continuing the same approach Sovol has taken with earlier machines like the SV06 and SV08.

Sovol M1D at a Glance: Pricing and Kickstarter Launch

As a hybrid IDEX toolchanger printer, the Sovol M1D combines up to seven colors or materials in a single print with near-zero purge waste. Backed by five-second toolhead swaps, automated calibration and print monitoring, plus an open-source hardware and software design that lets users customize the machine to their own needs, it’s a compelling entry point for makers and small studios who have been priced out of professional multi-material systems.

The Sovol M1D launches soon on Kickstarter. Without enclosure, early bird pricing is set at $1,299, with a $20 deposit locking in a VIP price of $1,199. With enclosure, early bird pricing is set at $1,599, with a $20 deposit locking in a VIP price of $1,499. For more details, check out Sovol’s website.
