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.

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

Improves Interlayer Bonding

Minimizes Moisture Impact

Ensures Process Consistency

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

Did You Know a Heated Chamber Can Warp Your Printer?

Ln 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

Printer Head Heat Protection

True Air Model Cooling

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.

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.

Frequently Asked Questions

What is the D400 HS best used for?

The D400 HS is built for professional, large-format prototyping and production. It excels at functional prototypes, tooling, jigs & fixtures, molds, and end-use parts across automotive, aerospace, consumer goods, and general manufacturing—especially when engineering-grade materials are required.

How much time can 600 mm/s high-speed printing actually save?

With a stable 600 mm/s print speed and a 90 mm³/s peak flow rate, the D400 HS can deliver up to 5× faster output compared with conventional machines. That means large prototypes and production parts can move from days to hours, dramatically accelerating design validation and throughput.

Can it print engineering materials like nylon and carbon fiber?

Yes. The 420 °C high-temp hotend, heated build plate, and actively heated chamber enable reliable printing of PA-CF, PA-GF, nylon, PC, ABS, ASA, PET-CF, and other engineering filaments. The integrated filament dry room also keeps hygroscopic materials ready to print.

Is it easy to operate for a typical engineer?

Absolutely. The 7-inch touchscreen, Klipper-based firmware, automatic mesh bed leveling, full-auto dual-nozzle calibration, and intuitive slicer workflow mean a standard engineer can be up and running quickly with minimal training.

Can high-speed printing still maintain high precision?

Yes. Deeply optimized Klipper motion control, a topologically optimized lightweight printhead, four independent Z-axis motors with real-time anti-tilt correction, and 0.001 mm eddy-current bed leveling work together to keep dimensional accuracy and surface finish excellent even at 600 mm/s.

What practical benefits does the dual-extruder system offer?

The dual-extruder setup supports multi-material and multi-color prints, lets you print complex geometries with soluble or breakaway supports, and provides a backup mode that can switch to the second nozzle if the first runs out of filament. The automatic nozzle shutter prevents oozing and cross-contamination.

What does the active 70 °C heated chamber do for engineering materials?

The active heated chamber maintains up to 70 °C, minimizing internal thermal stress, warping, and layer delamination when printing ABS, ASA, PA-CF, nylon, PC, and other engineering materials. It also reduces moisture effects on hygroscopic filaments, improving part strength and repeatability.
