The printer has a 305\u00d7305\u00d7280 mm working volume, CoreXY kinematics, and reinforced belts, allowing for precise printing at up to 600 mm\/s and acceleration of 20,000 mm\/s\u00b2. The bimetal nozzle heats up to 370\u00b0C, while the active 65\u00b0C chamber and heated bed up to 120\u00b0C ensure stability with technical materials such as ABS, ASA, PC, PA, and composites. Automatic Z-axis levelling and calibration guarantee a perfect first layer, and the machine is ready to print in just <strong data-end=\"1113\" data-start=\"1100\">10 minutes<\/strong> after unpacking.<\/p>\n<p data-end=\"1800\" data-start=\"1173\">QIDI Box turns Plus4 into a multicolor platform: the system accepts up to <strong data-end=\"1253\" data-start=\"1242\">4 spools<\/strong>, supports <strong data-end=\"1293\" data-start=\"1274\">up to 16 materials<\/strong> by connecting additional modules, and uses <strong data-end=\"1375\" data-start=\"1343\">hardened double gears<\/strong> for stable feeding even of carbon and glass fiber filaments. The built-in <strong data-end=\"1514\" data-start=\"1489\">65\u202f\u00b0C drying function<\/strong> keeps the filaments dry, while the <strong data-end=\"1558\" data-start=\"1545\">NFC chip<\/strong> recognizes the material and loads the correct profiles. QIDI Box automatically changes the rolls when they run out, monitors tangling and clogging, and thus ensures continuous printing.<\/p>\n<p data-end=\"2502\" data-start=\"1802\">The printer can be controlled via Wi-Fi, Ethernet, or USB and can be operated via a mobile app or computer with local or cloud access options. A <strong data-end=\"2013\" data-start=\"1997\">1080p time-lapse camera<\/strong> provides remote monitoring of the process. QIDI Studio, a new slicing software, is optimized for multicolor systems, and the printer also supports Orca, Cura, and PrusaSlicer. The package includes a <strong data-end=\"2307\" data-start=\"2293\">Cool Plate<\/strong><strong data-end=\"2346\" data-start=\"2309\">, a 0.2 mm tungsten bimetal nozzle<\/strong>, and a <strong data-end=\"2367\" data-start=\"2349\">filament roll<\/strong>, making the kit ready to use and suitable for engineers, designers, and small manufacturers.<\/p>\n<h2>Technology and print quality<\/h2>\n<p><strong>The QIDI Max4 Combo<\/strong> operates on <strong>Fused Deposition Modeling (FDM)<\/strong> technology \u2013 melting and laying down filament layer by layer. The CoreXY architecture with 1.5GT belts and FOC closed-loop stepper motors in the X\/Y axes ensures stable movements, minimal vibrations, and clean contours even at high-speed printing. The Z axis uses two 2 mm lead screws and an anti-backlash nut, which reduces &#8220;roll&#8221; effects and ensures very even layers in tall models.<\/p>\n<p>The print head is equipped with a <strong>bimetallic, hardened 0.4 mm nozzle<\/strong> (options 0.2\/0.6\/0.8 mm) and a ceramic heating module capable of reaching <strong>370\u00b0C<\/strong>. This allows the Max4 to work not only with standard filaments such as PLA and PETG, but also with engineering materials such as <strong>ABS, ASA, PA\/nylon, PC<\/strong>, as well as a variety of carbon and glass composites (PLA-CF, PETG-CF, PA-CF, PA-GF, PPA-CF, PPS-CF, etc.) when using appropriate nozzles and profiles.<\/p>\n<p>The bed consists of an aluminum plate with a silicone heater and a double-sided PEI platform, with an operating temperature of up to <strong>120\u00b0C<\/strong>. This ensures strong adhesion of the first layer and resistance to warping in large ABS\/ASA\/PC parts. With standard settings, the layer thickness for high-quality surfaces is in the range of <strong>0.12\u20130.2 mm<\/strong>, which can be increased for rough prototypes and reduced for finer details (at the expense of printing time).<\/p>\n<p>The camera is actively heated to <strong>65\u00b0C<\/strong> by an independent PTC heater and feedback fan. This environmental control minimizes internal stresses in the material and cracking in tall models, especially with engineering filaments. Together with the semi-enclosed print head and the optional <strong>Polar Cooler<\/strong> module, the system keeps extrusion stable while also allowing PLA to be printed in a heated chamber without softening or clogging.<\/p>\n<h2>Productivity and workflow<\/h2>\n<p>The QIDI Max4 Combo is designed for high productivity. The maximum head movement speed is 800 mm\/s, and the officially stated maximum kinematic performance of the hotend is 40 mm\u00b3\/s. Thanks to the Klipper firmware, input shaping, and intelligent acceleration control, significantly higher speeds than classic FDM machines can be used without a drastic loss of quality. With typical settings for high-speed PLA\/ABS, the machine operates at around 20\u201330 mm\u00b3\/s, which is sufficient for rapid prototyping and small series production.<\/p>\n<p>The work process is automated as much as possible:<\/p>\n<ul>\n<li><strong>Automatic leveling<\/strong> \u2013 the nozzle acts as a sensor (load cell sensor), which eliminates offset errors between the sensor and the nozzle and ensures a precise first layer without manual adjustments.<\/li>\n<li><strong>AI camera<\/strong> \u2013 a built-in camera with up to 1080p resolution monitors the print and can detect spaghetti and other anomalies, as well as record time-lapse videos to document the process.<\/li>\n<li><strong>Power failure protection<\/strong> \u2013 function for restoring the seal after a power failure.<\/li>\n<li><strong>End-of-thread and tangling sensor<\/strong> \u2013 warns when the filament is running out; when working with QIDI Box, tangling detection is also activated and automatically switches to another spool.<\/li>\n<li><strong>3-in-1 filter<\/strong> \u2013 a combination of G3 pre-filter, HEPA H12, and activated carbon to capture dust particles and volatile organic compounds in the closed chamber.<\/li>\n<\/ul>\n<p>Control is via a <strong>5-inch 800\u00d7480 touchscreen<\/strong>, mobile app, desktop software, and\/or browser. The built-in 32 GB eMMC memory and USB 2.0 port allow printing from local files, while <strong>2.4\/5 GHz Wi-Fi<\/strong> and <strong>Ethernet<\/strong> enable printer management via the QIDI cloud platform.<\/p>\n<h2>Compatibility and ecosystem<\/h2>\n<p>The official slicer is <strong>QIDI Studio<\/strong> \u2013 professional software with ready-made profiles for the printer and the full range of QIDI filaments, including engineering composites. Thanks to the <strong>Klipper<\/strong> firmware, Max4 is also compatible with popular third-party slicers such as <strong>OrcaSlicer<\/strong> and <strong>PrusaSlicer<\/strong>, which facilitates integration into existing workflows.<\/p>\n<p>Supported cutting formats include <strong>STL, OBJ, 3MF, STEP\/STP<\/strong>, and the software is available for <strong>Windows, macOS, and Linux<\/strong>. This makes the printer convenient for mixed teams and educational organizations.<\/p>\n<p>The heart of the Combo kit is the <strong>QIDI Box<\/strong> \u2013 a multi-material system that can feed up to 4 filaments from a single box and &#8220;chain&#8221; up to 4 pieces, for a total of up to 16 different materials\/colors. The QIDI Box has its own heated chamber up to 65\u00b0C for active filament drying, automatic spool switching, and options for printing with soluble support materials. This makes the Max4 Combo fully ready for multi-color, multi-material, and even technically complex printing (e.g., solid detail + soluble supports).<\/p>\n<h2>Design, ergonomics, and safety<\/h2>\n<p>The body of the QIDI Max4 is constructed from a steel chassis with plastic and glass panels. The printer measures 558\u00d7578\u00d7612 mm, and the net weight of the Max4 Combo is approximately 46.5 kg, indicating a robust construction and good vibration stability. The glass front window provides good visual access to the camera, while the built-in lighting and RGB status indicator make it easy to monitor the process.<\/p>\n<p>Practical details such as <strong>smooth surfaces<\/strong> on the base for easy cleaning, <strong>handles on the bottom<\/strong> for moving, and well-organized cable management make the machine more convenient for everyday use in an office, laboratory, or workshop. The chamber uses multiple sensors and closed-loop temperature control, and fire-resistant materials in the chamber construction add an extra layer of passive protection.<\/p>\n<p>The 3-in-1 filter module is highly recommended when working with ABS, ASA, PC, and composites, as it helps reduce particle and odor concentration in the room. Together with proper room ventilation and following the instructions in the official manuals, this provides a safe basis for continuous printing.<\/p>\n<h2>Professional usage scenarios<\/h2>\n<ul>\n<li><strong>Engineering prototypes and functional parts<\/strong> \u2013 the large 390\u00d7390\u00d7340 mm build volume allows for printing machine housings, industrial covers, assembly jigs, and fixtures from materials such as PA-CF, PA-GF, PC, and PPS-CF. The active chamber and high nozzle temperature help achieve strong, heat-resistant parts suitable for test assembly and real-world operation (within the polymer&#8217;s specifications).<\/li>\n<li><strong>Cosplay, props, and decor<\/strong> \u2013 Max4 can print <strong>full-size helmets, armor, and large props in one piece without cutting multiple segments<\/strong>. PLA and ABS details benefit from the evenly heated bed and chamber, which reduces warping and the need for complex post-processing.<\/li>\n<li><strong>Small batches and customized production<\/strong> \u2013 with QIDI Box, you can produce small batches of parts with different color schemes, marking options, or six-digit traceability codes without manually changing spools. Automatic filament refilling allows for long prints in 24\/7 mode.<\/li>\n<li><strong>Molds and fixtures for composite materials<\/strong> \u2013 the large chamber is particularly suitable for printing molds for vacuum forming, carbon, and fiberglass. The uniform temperature and stable geometry facilitate subsequent sanding and release agent application.<\/li>\n<li><strong>Education and R&amp;D<\/strong> \u2013 In university and corporate laboratories, Max4 serves as a bridge between desktop and industrial 3D printing. The ability to work with different materials and the open profiles in Klipper make it suitable for experimenting with process parameters and new filaments.<\/li>\n<\/ul>\n<h2>Restrictions and best practices<\/h2>\n<p>Despite its high capabilities, the QIDI Max4 Combo has some practical limitations and configuration requirements:<\/p>\n<ul>\n<li><strong>Warpage and cracking in very large ABS\/PC parts<\/strong> \u2013 a 65\u00b0C chamber significantly reduces this risk, but for extremely large or thick parts, it is recommended to use brim\/raft, special adhesives for PEI, and avoid sudden temperature changes during cooling.<\/li>\n<li><strong>PLA in a heated chamber<\/strong> \u2013 at high temperatures, PLA can soften in the area of the feed gears. Polar Cooler and active extruder cooling minimize this problem, but it is good practice to limit the temperature in the chamber for PLA and use QIDI profiles for this material.<\/li>\n<li><strong>Very soft TPUs (below 85A)<\/strong> \u2013 officially, a hardness of around 95A is recommended; for softer TPUs, you need to reduce the speed and retractions, and sometimes compromise on quality. It is advisable to follow specialized TPU guides and test gradually.<\/li>\n<li><strong>Filament moisture<\/strong> \u2013 nylon, PC, and composites are highly hygroscopic. Use the QIDI Box for drying during printing and store spools in dry boxes to avoid cracking, bubbling, and poor adhesion between layers.<\/li>\n<li><strong>Maintenance<\/strong> \u2013 periodically clean the PEI plate with isopropyl alcohol, check the condition of the belts and linear guides, and monitor the filter. Firmware and software updates from QIDI improve stability and add features, so it is good practice to apply them regularly.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<div class=\"t4s-liquid_custom_liquid_8AENwA t4s-pr__custom-liquid t4s-rte--list\">\n<div class=\"custom-short-description\">The QIDI Max4 Combo is a closed CoreXY 3D printer with a huge build volume of 390\u00d7390\u00d7340 mm, an active 65\u00b0C chamber, and a 370\u00b0C bimetal nozzle for engineering materials.
