QIDI Technology has been committed to the development of high-quality, high-performance 3D printers. As a consumer-level mid-to-high-end leader, the company launches 3-4 types of new model 3D printers every year. The Qidi new i-series will be officially released in 2021, representing more advanced technology and pursuing the ultimate user experience.

The Qidi i-fast 3D printer is equipped with a heated chamber that can be heated up to 60°C, enabling the printing of stronger manufacturing-grade parts and industrial fixtures. It features an automatic dual extruder that can adjust the left and right extruder up and down according to the software, allowing for precision printing with PVA water-soluble support.

The i-fast 3D printer is capable of printing with metal filaments, such as BASF 316 stainless steel filaments, which requires sintering treatment in the post-processing stage. Its dual Z-axis structure, using QIDI's second-generation design with all linear industrial guide rails, doubles the printing speed compared to DIY structure 3D printers on Amazon. The printing speed is increased by 20%, and the fastest printing rate is 100cc/h, with a 20% improvement in printing precision compared to the frame structure.

The latest version of Qidi Tech's slicing software, 6.4.1, features a redesigned UI interface that is more convenient to operate. The software's slicing algorithm has been improved, resulting in a 30% increase in print quality and a 20% increase in speed. The Qidi Print software is compatible with all types of Qidi Tech 3D printers and is available for free, serving as an alternative to paid software.

The Qidi i-fast 3D printer's normal extruder can print a wide range of filaments, including PLA, ABS, TPU, PETG, and PVA, while the high-temperature extruder can handle materials like Nylon, Carbon fiber, and PC. With a large printing size of 330mm x 250mm x 320mm, the i-fast can accommodate the printing of larger models in a single session.

The i-fast 3D printer also features a filament run-out sensor and a camera, providing enhanced monitoring and control capabilities. Additionally, it offers a 2-year warranty, including an extra year beyond the standard 1-year coverage.

Overall, the Qidi i-fast 3D printer delivers a seamless user experience, with its advanced features, such as the heated chamber, automatic dual extruder, and compatibility with a wide range of filaments, making it a compelling option for both novice and experienced 3D printing enthusiasts.
