Selle Italia SLR 3D: the Iconic saddle reinvented with 3D printing technology
New SLR 3D: when an Icon evolves.
During the Maratona dles Dolomites 2025, one of Europe’s most celebrated cycling events, Selle Italia unveiled a revolutionary evolution of its most iconic model — the SLR saddle. With the launch of three new versions, two of which feature cutting-edge 3D-printed padding, Selle Italia once again confirms its leadership in the field of cycling innovation.
Developed in collaboration with Prototek, a leading provider of high-performance 3D printing technologies, the SLR 3D series showcases the power of additive manufacturing applied to sports engineering. Prototek’s expertise in Carbon DLS™ technology and advanced technopolymer materials made it possible to create an entirely new generation of saddles that combine comfort, precision, and durability like never before.
Reinventing the SLR: new models for a new era
The two flagship models leading this transformation are:
Both share the legendary ergonomic design and structural engineering typical of Selle Italia’s premium range but differ in weight, frame composition, and performance focus.
The SLR 3D Carbon is designed for those seeking maximum performance with minimal weight. Built with full carbon rails, it is currently the lightest 3D-printed saddle on the market. Its combination of Carbon DLS™ technology and Prototek’s advanced 3D printing process results in an ultralight structure that offers high stiffness without sacrificing comfort, perfect for riders chasing extreme performance.
Meanwhile, the SLR 3D Elite offers a balanced blend of comfort and strength, thanks to its lightweight tubular steel frame. It’s the ideal choice for cyclists who prioritize comfort and reliability over long distances while still benefiting from Selle Italia’s advanced 3D technology.
3D-printed innovation: the core of the SLR 3D
At the heart of the SLR 3D saddle lies its groundbreaking 3D-printed padding, created using Carbon DLS™ (Digital Light Synthesis) , one of the most advanced technologies in additive manufacturing.
This innovative process allows Prototek to print complex lattice structures with variable density, ensuring targeted cushioning that adapts to every rider’s anatomy and pedaling style.
What makes this material truly exceptional is the use of EPU 46, an advanced elastomeric polymer designed to provide:
Variable-density comfort, adapting perfectly to different pressure zones.
High energy return, reducing muscle fatigue during long rides.
Exceptional lightness, without compromising shock absorption.
Long-lasting durability, even under intensive or prolonged use.
This technology doesn’t just improve comfort, it transforms the riding experience. The lattice structure allows for optimized vibration damping, enhanced flexibility, and superior breathability, keeping the saddle cool and comfortable even during endurance rides.
Design meets performance
Beyond its technical innovation, the SLR 3D impresses with its aesthetic design: minimalist, sleek, and unmistakably Selle Italia.
The visible 3D lattice pattern gives it a modern, high-tech appearance, while every detail is engineered for maximum functionality.
The superflow central cut-out drastically reduces perineal pressure, enhancing comfort and blood flow. Combined with the ergonomic shell and adaptive 3D cushioning, it ensures perfect weight distribution and efficient power transfer with every pedal stroke.
Whether you choose the Carbon or Elite version, both deliver an unmatched balance of lightness, flexibility, and control, setting a new standard for performance cycling saddles.
Prototek: technology Partner for sports development
Being chosen by Selle Italia, a brand that has represented excellence in global cycling for over 120 years, is a source of great pride for Prototek.
This collaboration brings together two companies united by the same values: a commitment to continuous research, quality manufacturing, and technology serving athletic performance.
Prototek contributed its deep know-how in industrial 3D printing, advanced materials, and scalable precision manufacturing, enabling Selle Italia to develop a product that’s both innovative and performance-driven.
The partnership demonstrates how digital manufacturing can empower traditional craftsmanship, opening new possibilities for product customization and efficiency in the cycling industry.
Beyond technology: passion in motion
The new SLR 3D Carbon and SLR 3D Elite represent much more than a technical upgrade. They are a symbol of how innovation and tradition can coexist, enhancing the rider’s experience through continuous evolution.
Selle Italia’s approach reflects a deep understanding of cycling’s emotional and physical demands. Every detail, from the saddle’s geometry to its lattice pattern, is the result of meticulous testing and an unwavering passion for excellence.
With this new line, Selle Italia once again proves its ability to evolve while preserving its heritage, and Prototek is proud to have played a key role in bringing this technological breakthrough to life.
A new generation of cycling comfort
The SLR 3D saddle stands as a testament to the future of cycling — where comfort, technology, and performance merge seamlessly. Its 3D-printed Carbon DLS™ padding, EPU 46 elastomer, and precision-engineered design make it one of the most advanced saddles ever produced.
Whether you are a professional athlete, an amateur cyclist, or simply passionate about innovation, the Selle Italia SLR 3D offers a tangible advantage in every ride.
By merging Italian design heritage with cutting-edge 3D printing, Selle Italia reaffirms its position at the forefront of cycling innovation, proving that the future of performance and comfort is already here, and it’s printed in 3D.
