Product description: 3D printer - QIDI Max4 Combo
The QIDI Max4 Combo is a large-format, enclosed CoreXY 3D printer bundled with the QIDI Box system for automated multi-color and multi-material printing . Its 390 x 390 x 340 mm build volume allows for large models, while a hotend reaching 370°C , a heated bed up to 120°C , and an actively heated chamber up to 65°C enable working with a wide range of filaments , including technical and composite materials. Maximum head speed is 800 mm/s , acceleration up to 30,000 mm/s², and maximum hotend flow of 40 mm³/s. The design utilizes closed-loop FOC motors, an X-axis linear guide, 1.5GT belts, and a precise Z-axis system with 2 mm pitch screws. The equipment also includes automatic Load Cell leveling, AI camera, 3-in-1 filtration, Input Shaping , and communication via WiFi, Ethernet and USB , while the QIDI Box expands printing capabilities with automatic multi-filament support.
3D Printer - QIDI Max4 Combo.
The 390 x 390 x 340 mm working area allows you to produce large models and many smaller parts in one cycle.
Large-format 3D printing with the fast CoreXY system
The 390 x 390 x 340 mm build volume allows for the production of large parts without having to divide the project into multiple smaller parts. This spacious area can also be used to accommodate multiple models and produce short runs in a single job. The CoreXY mechanism features a metal structure, an X-axis linear guide, steel Y-axis shafts, and 1.5GT 10 mm wide belts for stable head guidance. Closed-loop FOC motors enable movement speeds of up to 800 mm/s and accelerations of up to 30,000 mm/s² , making the Max4 Combo suitable for both rapid prototyping and the production of complex functional parts.
Stable Z-axis and automatic first layer calibration
The build platform is guided by two independent Z-axis drives with 2mm pitch screws and four 12mm diameter steel linear shafts. Backlash limiting nuts support precise platform positioning and layer-by-layer repeatability when printing tall models. Automatic leveling utilizes a Load Cell sensor integrated into the hotend , allowing the nozzle to directly measure the bed surface. This solution eliminates the offset typical of a separate probe , and the Input Shaping function additionally helps compensate for mechanical vibrations that occur during rapid changes in direction.
Two independent drives, 2mm pitch screws and backlash limiting nuts support accurate platform positioning.
370°C hotend and actively heated chamber for technical materials
The QIDI Max4 Combo allows you to work with a wide range of materials thanks to a hotend that reaches temperatures up to 370°C, a heating bed up to 120°C , and a chamber that can be actively heated up to 65°C . The direct extruder utilizes dual hardened steel gears and works with a wear-resistant bimetallic nozzle, which is especially important when working with filaments containing fiber additives. The hotend's maximum flow rate of 40 mm³/s supports efficient material feeding during high-speed printing. The manufacturer anticipates using PLA , PETG , ABS , ASA , TPU , PA, PC, PPS-CF, PPA-CF, PA6-CF, PA6-GF , and other technical and composite filaments.
Uniform table heating and active cooling control
The 390 x 390 mm heating bed utilizes a full-surface silicone layer with densely spaced heating wires and thermal insulation . This design promotes even heat distribution, stabilizes surface temperature, and improves first-layer adhesion, which is particularly important when creating large models. The Max4 also utilizes an active cooling control system that works in conjunction with the chamber heating , allowing for better adjustment of thermal conditions to the material being used. The optional Polar Cooler directs cool air directly towards the extruder , reducing excessive filament heating and the risk of filament blockage when operating at elevated chamber temperatures.
A full-surface silicone layer with densely spaced heating wires supports even heat distribution.
Automatic spool switching in the QIDI Box allows the system to continue feeding material from the next spool after the current one has run out.
QIDI Box - multi-color and multi-material printing in Max4 Combo
The most important enhancement to the QIDI Max4 Combo version is the included QIDI Box system, which automates filament feeding and switching during printing. It allows for the creation of multi-color and multi-material models, as well as the use of different model and support materials in a single project. The QIDI Box offers filament drying at up to 65°C during printing and an automatic spool switching function, allowing you to continue printing from the next spool after the material runs out. The system can be expanded by connecting up to four QIDI Box modules, allowing you to work with up to 16 materials , significantly increasing the possibilities of creating complex models.
AI Camera, 3-in-1 Filtration and Print Process Control
The built-in camera with a resolution of up to 1080p allows you to observe the progress of the job and create Timelapse recordings, and AI functions help detect selected printing problems , including the formation of the so-called The printer features a filament end sensor , while the compatible QIDI Box expands material control with features such as filament tangling detection. The 3-in-1 filtration system utilizes a G3 pre-filter, HEPA H12, and coconut shell activated carbon , and according to the manufacturer, captures 99.5% of dust and particles. Operation is facilitated by a 5-inch 800 x 480 px touchscreen , 32 GB eMMC memory, and Wi-Fi, Ethernet, and USB connectivity.
AI camera up to 1080p: allows you to observe the print, create a Timelapse and detect selected irregularities.
The QIDI Box included in the kit expands the printer's capabilities with automatic support for multiple filaments and multi-color and multi-material printing.
QIDI Max4 or Max4 Combo - differences between variants
Both variants utilize the same QIDI Max4 platform, offering a build volume of 390 x 390 x 340 mm, a hotend up to 370°C, a bed up to 120°C, a heated chamber up to 65°C , and the same CoreXY design. The standard Max4 is compatible with the QIDI Box, but the module is not included in the standard equipment of this variant and can be purchased as an upgrade. The Max4 Combo is factory-installed with the QIDI Box , providing automatic multi-filament handling, multi-color and multi-material printing, and in-module material drying. The Combo variant is therefore primarily intended for projects that require the functionality of a multi-material system without the need for subsequent upgrades.
