Its AI-driven monitoring, ultra-fine 50 µm motion accuracy, and automatic calibration ensure consistent, professional-grade results, making it ideal for industrial prototyping, advanced R&D, and professional manufacturing workflows. Purge Saving Multi-Material Printing Using the H2C, it is possible to print as many as seven distinct materials in one pass without needing to purge any nozzles. Merge various material characteristics into a single continuous form and elevate integrated design to an unprecedented level. Integrated TPU Joints for Multi-Color Parts Print durable TPU ball joints for your robot models flexible long-lasting and built for endless motion. Multi-Material Printing With Minimal Purge Waste In conventional single-nozzle multi-material printing, it is necessary to flush out any remnant material when switching filaments. Vortek revolutionizes this process by utilizing a smart hotend-swapping mechanism that substitutes the complete hotend, resulting in quicker, cleaner prints with reduced waste. Fully Automatic Filament Change and Always Delivering the Most Efficient Conversation The Vortek system integrates flawlessly with our dependable AMS (Automatic Material System), enabling the complete automation of the filament replacement procedure, eliminating the necessity for manual loading of each filament into the toolhead. Small Form Factor, More Filaments As only the hotend is exchanged, the setup can accommodate as many as six hotends which are not changeable without greatly decreasing the build capacity. This allows for an increased variety of materials, colors, and options, all within a single print. 8-Second Induction Heating and Contactless Design for Reliability Our top tier induction heating technology heats the nozzle within 8 seconds, greatly minimizing the preheating duration required for changing materials when compared to conventional techniques. Our strict criteria for dependability prompted us to shift from using metal pins that rely on contact, as they are susceptible to oxidation and inconsistent connections. We created a solution without physical contact that guarantees a consistent, high-frequency link, which is essential for accurate temperature management and synchronized intelligent hotend operation. Enclosed for High Performance Printing and Fully Automatic Nozzle Offset Calibration Featuring a continuous enclosure and a flexible air circulation system, the H2C ensures a consistent environment temperature for top quality materials while also purifying the air to create a tidy and secure workspace. Our calibration process for inductive nozzle offset is entirely automated, requiring no manual intervention, calibration plates, or additional setup. Within a matter of minutes, the H2C accurately adjusts the nozzle offset to a tolerance of 25 microns. Dedicated Hotends for Specific Filaments The Vortek system of the H2C allows you to assign one of its six swappable hotends to particular filaments, significantly transforming the use of important engineering substances. This guarantees enhanced reliability and uniformity in printed results. Additionally, each hotend can automatically remember filament data, allowing for an immediate pairing with the appropriate hotend when that same material is loaded again. Smooth Surface, Sharp Edges The H2C utilizes the servo motor within the extruder along with high-resolution eddy current sensors positioned at the nozzle to detect the dynamics of extrusion. This capability allows for accurate control of the extrusion process and the automatic adjustment of Pressure Advance (PA) settings for every filament, leading to smoother surfaces and more defined, sharper edges. Flexible Network Security & Connectivity The H2C provides easy access to cloud connections for controlling the device remotely from any gadget. For applications that require high security, it also offers comprehensive offline capabilities, guaranteeing total physical separation. Users can manage the printer, transfer files, and perform firmware updates without requiring internet access. For those with advanced skills, Developer Mode allows access to the MQTT port, enabling the integration of external components and software. Features: The H2C supports multi material printing for up to 7 different materials, allowing you to produce complex parts in a single run while completely eliminating the need for nozzle purging or creating material waste.
