Formnext 2025 in Germany brings one other wave of business 3D printing launches, and QIDI is utilizing the occasion to introduce its new flagship system: the QIDI Max4. Positioned as the biggest print-size choice amongst consumer-grade enclosed printers, the Max4 goals to sort out a long-standing problem on this section: the “problem in attaining each massive print dimension and excessive precision.”
Based on QIDI, the Max4 combines a considerably expanded construct quantity with movement management, thermal administration and automation options designed for skilled customers who need to produce massive elements with out compromising on element or reliability.
Massive construct quantity with uniform thermal management
The QIDI Max sequence has constructed its repute on large-format and versatile printing, and the Max4 pushes that additional. The system presents a construct quantity of 390 × 390 × 340 mm, which QIDI states is 55% bigger than the earlier Max3. This dimension targets purposes akin to massive industrial elements, intricate molds and customised prototypes, the place single-piece builds can cut back meeting steps and potential weak factors.
To assist this envelope, the Max4 makes use of a 390 × 390 mm heated mattress with a full-surface silicone thermal layer and densely distributed heating wires. QIDI highlights this as one of the uniform heating designs in its class. A high-efficiency insulation cotton layer beneath the mattress additional stabilizes temperature throughout the floor. Collectively, these components are meant to enhance first-layer adhesion and preserve large-format prints secure, with decreased danger of warping throughout the construct plate.
Excessive-flow extrusion and managed printing surroundings
On the extrusion facet, QIDI equips the Max4 with a brand new high-flow hot-end rated at 40 mm³/s. That is designed to allow considerably sooner print speeds, notably helpful when filling a big construct quantity, and to assist cut back general manufacturing cycles for sizable elements.
The nozzle is comprised of hardened metal, which broadens materials compatibility past fundamental filaments. QIDI lists assist for traditional PLA and ABS, alongside some industrial supplies akin to abrasive carbon fiber–bolstered nylon. This mix of upper circulate and wear-resistant {hardware} is geared toward customers who want throughput and composite functionality on one machine.
Thermal management extends past the mattress and hot-end. The Max4 debuts QIDI’s self-developed Energetic Toolhead Cooling System, known as the “Polar Cooler.” This technique directs cooled air instantly onto the extruder and filament path to enhance warmth dissipation and assist forestall clogs throughout demanding jobs.
In parallel, the printer makes use of a second-generation Energetic Chamber Heating system that may keep an inside temperature of as much as 65°C with optimized air circulation. QIDI positions this as a key enabler for high-temperature supplies, naming ABS, ABS-CF and PC as examples that profit from a heated surroundings and secure airflow.
Movement system upgrades for stability and precision
To enhance print stability and half high quality at pace, the QIDI Max4 introduces a brand new closed-loop motor system on the XY axes. As a substitute of working open-loop, the motors work with a closed-loop encoder that displays errors and compensates for deviations on the fly.
QIDI outlines three most important advantages of this method. First, higher stability: the system goals to forestall step loss and cut back layer misalignment over lengthy or advanced jobs. Second, improved accuracy: decreased torque ripple is meant to decrease floor artifacts akin to seen rippling or cogging. Third, enhanced effectivity: the closed-loop motors are designed to run cooler and quieter at excessive speeds, which may reduce thermal impression on inside elements and contribute to an extended operational lifespan.
Z-axis efficiency receives related consideration. The Max4 makes use of 2 mm lead screws mixed with an anti-backlash nut to take away vertical play and keep constant positioning. This configuration is geared toward smoother Z movement and better Z-axis accuracy, with the aim of minimizing layer strains and enhancing floor element, particularly on tall elements that occupy a lot of the printer’s construct peak.
Past the core movement elements, QIDI provides a number of supporting options: a brand new auto-leveling sensor, industrial-grade linear rails and customized 1.5GT belts. Collectively, these components are meant to ship smoother, extra exact movement management whereas enhancing the machine’s sturdiness below frequent use.
AI monitoring, interface updates and QIDI BOX integration
On the usability and automation facet, the QIDI Max4 introduces an AI recognition system constructed round a high-performance processor. Utilizing a high-definition digital camera, the printer repeatedly displays the print in actual time and analyzes picture information alongside print instructions. When it detects points akin to “spaghetti” failures or issues in assist constructions, the system can routinely pause the print and ship an alert. That is designed to chop down on wasted materials and cut back the necessity for fixed guide supervision on longer jobs.
The consumer interface has been up to date as effectively. A brand new massive display and redesigned UI purpose to supply smoother fingertip management and a extra trendy interactive expertise, from setup to monitoring.
For multi-color and multi-material workflows, the Max4 could be paired with the QIDI BOX. This accent extends the printer’s capabilities by supporting as much as 16 colours concurrently and offering filament drying at temperatures as much as 65℃. Together with the printer’s high-temperature chamber and hardened nozzle, this setup is positioned to be used instances starting from multi-color inventive fashions to engineering-grade composite elements and complicated, multi-material objects.
Market positioning, availability and gross sales plans
With its bigger construct quantity, bolstered movement system, high-flow hotend, chamber heating and AI-driven monitoring, the QIDI Max4 is offered as the brand new flagship in QIDI’s lineup. The corporate frames the system as a aggressive entry within the large-format enclosed desktop section, focusing on skilled customers who need greater effectivity, secure efficiency and an more and more automated consumer expertise in a single machine.
QIDI states that the Max4 is now out there for world pre-order by means of its official channels.
Based on the Qidi official web site, BFCM gross sales will launch immediately on November 18th, and clients can look ahead to upcoming promotions there.
By combining high-temperature functionality, precision-focused movement management and expanded multi-material choices by way of the QIDI BOX, the Max4 positions itself as a large-format platform for each useful and inventive work. Its launch at Formnext 2025 underlines QIDI’s intention to develop its position within the skilled 3D printing house and to compete extra instantly within the large-format class.
