Check on Kickstarter
3D printing has long traded speed for efficiency and versatility for convenience. L4 changes the equation with its independent 4-head architecture.
Each head handles one color or material, enabling zero purge waste during 4-color printing while reducing overall material waste. With heads pre-loaded and independently positioned, color changes take just one second, minimizing switching time and getting prints done faster.
With four independent heads printing four identical models simultaneously, L4 delivers 4X output in the same amount of time, maximizing production efficiency.
Stop designing around your printer’s limitations. With up to 354 x 370 x 386 mm³ of massive usable build volume and an optional Auto Filament Expansion & Dry System (FEDS) supporting up to 16 colors, L4 lets you print larger, more vibrant models in one piece.
The L4 brings studio-grade motion to your desktop. Closed-loop linear motors, built for 50,000+ hours of stable service life, keep every print precise and error-free. A die-cast frame and active anti-vibration (in mirror mode) reinforce each other, holding accuracy steady at high speed with no layer shifts or defects.
Strange Parts went behind the scenes at LightMake’s Shenzhen headquarters and factory to explore how the L4 moves from R&D to production. He toured the linear motor assembly line, R&D labs, testing areas, and product iteration process, and also sat down with LightMake Founder Vic Wong to learn about the engineering behind L4.

“Instead of putting four separate printers on my desk, LightMake put four independent print heads into one machine.” — The Q
We invited The Q to take a closer look at LightMake L4 and its four independent printheads. In his latest video, he explores how the linear motor system, near-zero purge waste, and 4X Batch Printing come together to deliver a new approach to multi-color and high-efficiency printing.
3D Printing Zone, who has tested more than 55 3D printers since 2017, recently put the LightMake L4 through a series of hands-on tests. The video covers its linear motors, multi-color printing, print quality, and 4X Batch Printing, including four Benchys printed simultaneously.
“The heaviest and most powerful multi-color printer I’ve ever owned.”
Meet Lightmake L4, An Unprecedented Productivity Beast.
Four independent heads make it a productivity beast, and they never get in each other’s way. Every head follows its own planned path, coordinated by hardware and software in real time, whether they collaborate on one model or run four in a batch. Swaps take one second, not five.
Replace four printers with one. The LightMake L4 combines 4× batch production, large-format printing, and multi-color creation in a single production platform. Save upfront costs, free up 38% more workspace, and switch seamlessly between three printing modes.
Bypass the slow, sequential batch printing of traditional machines. The L4’s 4 independent heads operate simultaneously to instantly quadruple your output. Produce four complete models in the exact time it takes to print just one.
Whether switching filament through a single nozzle or switching between toolheads, conventional systems can take 5–7 seconds or more, losing time to retraction, loading, or mechanical movement. L4 takes a different approach: four heads stay loaded and pre-heated, enabling instant handoffs from one head to the next and making multi-color jobs up to 79% faster*.
*Save over 79% time: calculated from internal testing on a 4-color fox model. Actual results vary with model geometry and color complexity.
*1s Tool Change refers to the mechanical switch time from when one toolhead stops printing to when the next takes over.
Stop bleeding profits on purge waste. Achieve zero purge waste. With four independent heads serving each color through dedicated nozzles, the L4 swapped massive, wasteful purge for a minimal prime tower. Every single gram you load builds your masterpiece.
A larger usable build volume means more freedom for every print. By optimizing the entire machine architecture, the LightMake L4 combines an independent four-head system with expansive printable space, so you never have to choose between productivity and creativity.
The result: a 354 x 370 x 386 mm³ chamber, the largest of any desktop printer, big enough to swallow a full-size basketball. Print massive models in one piece, with no slicing, no printing in parts, and no gluing. Just complete creative freedom.
Color stops being a limit. Four heads keep four colors loaded for fast, clean everyday printing. When a design demands the full spectrum, the optional Auto Filament Expansion & Dry System (FEDS) takes the L4 up to 16 active colors, no manual swaps, no pausing, start to finish.
Note: Color switching may be slightly slower when using Auto Filament Expansion & Dry Systems (FEDS).
Print up to four materials in one go to simplify your workflow. By seamlessly combining rigid, flexible, and specialized support filaments in a single continuous print, removing post-processing and manual assembly from your timeline. This unconstrained freedom expands your design possibilities.
Engineering filaments warp and crack when a chamber cannot hold temperature. The closed heating chamber is an optional add-on that stabilizes the build environment for exactly those materials. Add it when your work calls for functional, load-bearing parts.
Your imagination, one build plate. Print oversized single-color pieces, rich multi-color and multi-material models, or a full batch of four, copied or mirrored in the same run. Three modes, four heads, zero reconfiguration. Pick it in the slicer and go.
Ditch the rubber belts and pulleys. Powered by 8 sets of XY linear motors, the L4 delivers a revolutionary leap in stability, precision, speed, and durability.
Open-loop steppers assume they arrived where they were told. The L4 checks. Position is monitored and corrected in real time to within ±1μm, so layer shifts stop happening. Print intricate threads or a large multi-part assembly, and the pieces fit together straight off the plate.

Harness ±1µm motion precision. The advanced linear motor maintains tight high-speed tolerances, ensuring all printed components interlock seamlessly. Deliver complex assemblies with near-zero manual sanding.
Cleaner surfaces, straight off the plate. Direct-drive linear motors turn current into motion with nothing in between, so acceleration is instant, stops are crisp, and ringing and ghosting all but vanish.
*Note: The linear motor’s true physical limit is vastly higher. We deliberately tuned the max print speed to 500 mm/s and acceleration to 20 m/s² to ensure stable, high-quality output.
Set it and forget it. Magnetic drive never touches the rail, so nothing wears down. That means about ten times the working life of belt systems and a 50,000+ hour service life with no drift. No tensioning, no replacements, no maintenance schedule at all.
Unleash your full creative potential. Stop letting massive purge towers, agonizingly slow color swaps, and ugly surface ringing ruin your masterpiece. Let your imagination flow without limits.
Full-scale prototyping with zero post-processing. Print large, multi-color models in a single continuous job. Skip the gluing and manual adjustments, and keep your workflow strictly focused on design.
Sharpen your competitive edge. Break through the limitations of slow output, frequent maintenance, and massive material waste. Shatter these traditional bottlenecks and achieve maximum ROI from a smart investment.
Stop losing prints on layer one. The L4 kills the two usual causes at once: each head lifts 5 mm to ride clear of drips and drags, while micron-level compensation nails adhesion. A gasket seals every idle nozzle, so warping and color bleed never get started.
Traditional mechanical calibration relies on theoretical offsets, ignoring real-world machining tolerances and extrusion drift. L4 solves this by scanning the actual print. Using optical sensors to capture the precise X/Y coordinates of the deposited material, it achieves a 30μm absolute alignment for flawless, zero-gap multi-material transitions.
Monolithic Die-Cast Frame
Achieve rock-solid stability. The monolithic die-cast frame provides unmatched structural rigidity to drive consistent, high-speed performance. Guarantee naturally smooth finishes effortlessly.
Vibration Cancellation Algorithm
Virtually eliminate surface ringing. When printing symmetrical or mirrored models, advanced algorithms perfectly balance the opposing toolhead movements across the X/Y axes. This effectively neutralizes mechanical vibrations, delivering remarkably smooth surface finishes.
Every color, exactly as you designed it. Each runs through its own dedicated nozzle, physically isolated, so nothing shares a melt zone, and nothing contaminates anything. The result is flawless 1:1 true color, crisp edges, and clean boundaries that hold precisely where you drew them.
Scale your print farm effortlessly. By connecting your entire fleet to a single unified network, you can dispatch tasks to over 1,000 machines simultaneously with just one click. Drastically lower your management costs with one-stop control.
Just set your delivery deadline and let the AI handle the rest. The system actively analyzes your fleet’s real-time status and automatically allocates the exact number of machines needed to finish the order on time. Effortless, hands-free order fulfillment.
Build the ultimate one-person studio. Through smart OpenClaw integration, you can now command the L4 directly from WhatsApp. Just send a single text command, and the system automatically takes over to deliver a fully finished model right to your build plate.
Powered by Conversational AI, the L4’s intelligent engine translates your natural language instructions into optimal slicing parameters instantly. Bypass the frustrating manual setup process, flatten the learning curve, and boost your daily production output.
Recognizing that some users desire a larger print size, in addition to the L4, we are also preparing to launch the LightMake L1 version.
The LightMake L1 trades multi-color capability for pure scale. One head, the same linear motor core, and a 395 x 395 x 386mm chamber holding 60 liters. Print colossal models in a single continuous run and leave splitting, gluing, and manual finishing behind you.
Your workflow, your choice. Choose the L4 for seamless multi-color mastery, or the LightMake L1 if your work demands pure, expansive scale. Both models share the same elite core, engineered to deliver uncompromising performance for your specific projects.
*Auto Filament Expansion & Dry System(FEDS): Keeps filaments dry, automatically handles spool runouts, and ensures uninterrupted printing in scenarios requiring 5 or more colors.
