The D400 HS features a next-gen smart auto-raising dual-extruder kit, capable of reaching hotend temperatures up to 420 °C. The hotend can be quickly swapped for different nozzle sizes.

Enhanced with the upgraded Dual Nozzle Shutter technology, it delivers flawless printing with different support materials. Combined with a topologically optimized lightweight design, the printhead enables even higher printing speeds and greater motion agility.

Automatic Dual Nozzle Shutter

This innovative system features a precision mechanical shutter that automatically closes over the nozzle of the idle extruder the moment it lifts away. By creating a physical seal, it effectively prevents oozing and cross-contamination between materials, ensuring flawless multi-material and multi-color prints. It's the key to achieving pristine quality and reliability in every layer.

Scale Without Limits for High-Strength Prototypes

The CreatBot D400 HS was created to make industrial 3D printing of large-scale objects and prototypes as easy as possible. It is embedded with many advanced technologies for ultra-large, impressive prints. It will undoubtedly be your best choice if you are looking for an industrial large-scale 3D printer for prototyping with engineering-grade materials.

If you are tired of the fragility of PLA and the warping of ABS, try our revolutionary material, UltraPA-CF. By printing your large models with a large-diameter nozzle, you will get an oversized model with a high strength of 80MPa and heat resistance up to 150°C within days. It is the best choice for your prototype verification.

Active Heated Chamber | 70℃

The design employs a double-layer insulation cotton layer, allowing the cavity temperature to be raised to 70°C. This is crucial for preventing the shrinkage and deformation of large engineering materials.

• Reduces Thermal Stress & Warping

When printing large or high-strength engineering materials (e.g., ABS), uneven cooling causes internal thermal stress, leading to warping, delamination, or cracking.

• Improves Interlayer Bonding

In low-temperature environments, excessive temperature differences between molten and solidified layers weaken adhesion. A controlled heated chamber maintains optimal layer temperature, enhancing molecular diffusion for stronger interlayer bonding.

• Minimizes Moisture Impact

The heated chamber minimizes the impact of ambient humidity on hygroscopic filaments (e.g., Nylon), preventing bubbles or strength loss caused by moisture absorption during printing

• Ensures Process Consistency

For industrial production, chamber temperature stability is critical for part-to-part uniformity. Active temperature control eliminates environmental variability, guaranteeing reliable repeatability.

Did You Know a Heated Chamber Can Warp Your Printer?

In large-format FFF 3D printing, when chamber temperature rises, the printer frame and structural components also undergo thermal deformation—metal expansion, axis misalignment, and mechanical part displacement. These micro-distortions accumulate layer by layer, ultimately leading to:

• Layer Misalignment and Surface Roughness
• Loss of Dimensional Accuracy
• Structural Defects in Large Parts

This is why treating chamber temperature as an optional add-on, or claiming it can be retrofitted later, proves these manufacturers just don't get it. They have no compensation for machine deformation—some aren't even aware of the issue. They simply add it as a feature to drive sales, with total disregard for actual print quality.

With 8+ Years of R&D on the Chamber Temperature of FFF Industrial Printers

Our Solution: Intelligent Chamber Heating Algorithm

The intelligent chamber heating algorithm predicts and counteracts irregular deformations caused by chamber temperature variations.

The final result? Even if the machine has already deformed slightly, it can still print perfect parts!

The robust structure of the 3D printer (weight matters) significantly reduces deformation—the heavier the machine, the less distortion!

Outage Restore & Filament Detection & Backup Mode

The printer automatically memorizes the current position and saves print data when power is interrupted. Upon restart, it resumes printing from the exact point of interruption, eliminating the need to restart entire prints and saving valuable time and material costs.

The printer also prevents failed prints by pausing and alerting you when the filament runs out, allowing you to replace the spool and continue printing without losing progress.

Backup Mode: If the filament in the main nozzle (No. 1) is exhausted, the printer automatically switches to the secondary nozzle (No. 2) to continue printing, ensuring uninterrupted production even during filament changes.

Magnetic Suction Platform

Proprietary magnetic platform, large, easily removable, and heat-resistant over 100°C, and won't demagnetize over time.

For oversized models, it is easy to detach them quickly and the bottom of the model is flat. Convenient to all operators.

True External Air Cooling

• Medical-Grade Cooling Pump

Ultra-Quiet & Reliable: Equipped with a medical-grade pump, it delivers powerful, constant air pressure with minimal noise. Engineered for 24/7 operation, it ensures a quiet and stable workflow for professional environments.

• Printer Head Heat Protection

Reliable thermal defense for the print head against high chamber temperature during operation. Targeted cooling avoids heat-related failures for consistent precision and long service life.

• True Air Model Cooling

Flawless High-Speed Printing: Directs fresh external air to solidify material instantly. This 'cross-flow' cooling prevents sagging and stringing in heated chambers, delivering perfect overhangs and superior surface finish.

Ultra Air Filter System / 99.995% Adsorption

Our advanced air purification system employs a dual-filter design: an initial HEPA filter captures fine particles, while an activated carbon filter absorbs volatile organic compounds (VOCs) and odors. This ensures a clean and safe printing environment, protecting both the operator and the printed parts from harmful emissions.

WIFI, LAN, Internet, APP Control

In addition to cloud connectivity, CreatBot also supports local area network mode and physical connection operation. You can control the printer, send sliced files, and update firmware without an internet connection.

• Completely Offline
• Printer Control
• File Sending
• Firmware Update

Camera Control Technology

Camera control technology allows customers to control the printing process on speed, pause, temp., etc., with an APP remotely, achieving the best printing quality in the shortest time without failure. A very useful feature for large models and long-time printing.
