Continuous High-Speed 3D Printing

Our technology is based on continuous photopolymerization, an advanced evolution of traditional DLP printing. By utilizing a crytal clear, specialized porus window as the bottom layer of the resin tank, both light and oxygen can pass through simultaneously.The controlled oxygen flow creates a microscale liquid interface that prevents the cured resin from sticking to the tank bottom. This enables smooth, uninterrupted growth of the printed part, eliminating the slow peel-off step of conventional DLP. The result is a printing speed even faster than first-generation continuous 3D printing systems, along with guaranteed precision.

Unlike conventional release films made from FEP or PFA, our proprietary amorphous fluoropolymer films offer superior permeability, mechanical robustness, optical clarity, and thermal stability. This breakthrough allows for industrial-grade high-speed printing with outstanding reliability.

Custom sizes and thicknesses Standard: A4 (300 × 210 mm) and A5 (210 × 150 mm) at 100 µm; scalable to 700 × 350 mm.
First in China – We are the first company in China to achieve industrial-scale mass production of continuous 3D printing windows, backed by independent IP.
Superior performance – Optical transmittance equivalent to imported high-end films, with higher oxygen permeability and thermal resistance.
Cost-effective – Thanks to our outstanding supply chain management and cutting-edge material technologies, our films deliver better performance at significantly lower cost, with stable large-scale supply.

1. Advanced 3D Printing

Pyflon™ films offer exceptional UV transparency, chemical inertness, and non-stick surface energy, making them the ideal interface film for high-resolution photopolymerization and resin-based 3D printing systems. Their high purity and dimensional stability ensure defect-free curing and long-term durability even under repeated thermal and optical cycling.

2. Degassing and Vapor Management

With precisely tunable gas permeability and selectivity, Pyflon™ enables controlled venting of dissolved gases and organic vapors in critical systems. These films can act as degassing membranes in photoresist processing, semiconductor coating lines, and microfluidic systems, maintaining vacuum integrity while preventing moisture or oxygen intrusion.

3. Optical and Sensor Windows

The material’s broadband optical transmission (UV–IR) and chemical resistance make Pyflon™ suitable for spectroscopic sensors, gas analyzers, and vacuum viewports. Its amorphous structure ensures consistent refractive index and low birefringence, essential for precision optical measurements and laser systems.

4. Environmental and Energy Systems

Pyflon™ films exhibit stable performance in corrosive gas environments, fuel cells, and membrane reactors, providing both barrier and transport functionalities. Their intrinsic PFAS-free composition and non-leaching chemistry support sustainable development in green hydrogen, carbon capture, and advanced battery systems.
