Rolling Nanoimprint Lithography (RNIL): how it works
Stensborg supplies R2R and R2P nanoimprint lithography systems for industrial-scale production. The systems are designed with a modular and scalable architecture, allowing widths to be tailored to most project requirements.
Both our Roll-to-Roll (R2R) and Roll-to-Plate (R2P) processes rely on contacting a UV-curable resin with a patterned tool and curing it with light. The difference lies in the substrate type and production scale:
Stensborg’s Optical Engine, originating from our patented Holoprint℗ process, has been developed over more than 20 years of experience in making Holographic Optical Elements (HOEs) and nano feature replication.
Embedded in every system, our rolling imprinting technology delivers precise control over UV intensity, imprinting pressure, and rolling speed, guaranteeing feature replication down to 20 nm at high speeds for a wide variety of feature topologies, including life science nanostructures, micro-engravings, diffractive gratings, 4-level beam splitters, and functional surfaces.
Why Optical Engineering design is critical for nanoimprinting
In high-speed, roller-based nanoimprinting, throughput and reproducible nano-pattern fidelity depend on how accurately the resin is cured and pressed against the template. The nip design in Stensborg systems concentrates pressure along a narrow line rather than a broad surface, enabling consistent feature replication across large areas, reduced material stress, and lower energy consumption.
By optimising UV exposure time (Δt) and intensity (I), our Optical Engine ensures each resin layer is cured precisely during imprinting:
E=I×Δt
Where E is the energy delivered to the resin. This ensures high throughput without compromising accuracy, a critical factor for both industrial manufacturers and research laboratories.
Stensborg’s Optical Engine uses high-intensity, long-life UV LEDs, optimised at 395 nm, delivering exceptional resin compatibility and a lifespan of 10,000 hours, resulting in a maintenance-free operation.
Enhanced material compatibility ensures seamless processing across a wide range of substrates, including PVC, PET, PC, and flexible electronics materials, while minimising shrinkage, defects, and production downtime.
These technological advancements enable 10 to 100 times faster production than traditional plate-to-plate nanoimprint lithography, injection moulding, or batch processes. With stamp lifetimes reaching up to 70,000 impressions, Stensborg systems outpace competitors and set a new standard for nanoimprint lithography equipment for high-volume manufacturing.
Key advantages for researchers and manufacturers
High throughput & faster ROI
Continuous RNIL processes produce large-area nanopatterns quickly. With a 2–6× lower CAPEX than industry alternatives, Stensborg’s industrial-scale systems deliver ROI in months, thanks to cycle times up to 25× faster.
Cost and workflow efficiency
Stamp lifetimes of 10,000–70,000 cycles and reduced resin waste contribute to a more efficient production flow, achieving up to 80% cost reduction.
Large-volume scalability & manufacturing
Single-line scalability allows seamless progression from lab-scale prototyping and process validation to custom-built manufacturing equipment with imprint widths up to 500 millimetres. Time to market is reduced by integrating a start-to-finish development ecosystem, encompassing resin compatibility, in-house template manufacturing, custom design and assembly, delivery, and online training.
These advantages have made Stensborg a preferred nanoimprint lithography supplier for clients in key global markets, including the United States, Canada, France, Germany, and the Netherlands.
