Selle Italia Introduces Custom Pressure-Mapped 3D Printed Saddles

Selle Italia has announced the launch of Unica, a new line of 3D-printed bicycle saddles that utilize individual pressure-mapping data rather than standard, fixed cushioning zones. Built around existing shapes such as the SLR 3D and the Novus Boost Evo 3D, the manufacturing approach tailors the internal lattice network directly to an individual cyclist’s measured weight distribution.

Tailoring Internal Lattice Geometries

Traditional mass-produced 3D-printed bicycle components often feature uniform or zoned lattice configurations designed for broad groups of users. The Unica production pipeline shifts away from this template-based strategy by incorporating data collected through the idmatch pressure mapping system. This diagnostic tool records specific contact points and pressure concentrations while a cyclist rides.

According to the manufacturer, this information dictates the internal density and layout of the printed lattice structure. While the external physical housing of the saddle remains identical to the chosen base model, the internal architecture varies to target precise anatomical support needs. The company states that this design aims to enhance rider stability and alleviate concentrated pressure points over extended durations.

Position Adjustments and Maintenance

The company notes that minor shifts in bicycle geometry or riding posture do not necessarily render a custom saddle obsolete. Professional bike fitters can typically adjust the position of the Unica saddle on the current seatpost to accommodate minor setup changes. A new diagnostic mapping session is recommended only when adjustments significantly alter the rider’s overall weight distribution on the bicycle.

What This Means for South African Makers

Customised functional parts driven by personal biometric data highlight how additive manufacturing moves beyond simple hobbyist prototyping into targeted end-use products. For local designers and advanced makers exploring functional elastomers and flexible filaments, this application demonstrates the value of variable infill densities and custom geometries. While specialised medical and athletic customisation tools often rely on proprietary ecosystems, the underlying concept of tailoring internal lattice structures to solve ergonomic challenges is directly applicable to custom grips, insoles, and protective gear designed on desktop systems.

DC3D’s Take

The shift from static multi-zone cushioning to data-driven internal lattice customisation represents a logical progression for additive manufacturing in sports equipment. By keeping the outer shell standard while varying the internal print parameters, manufacturers can maintain consistent external compatibility with standard seatposts and hardware while tailoring the mechanical compliance of the part. It remains to be seen how accessible these advanced diagnostic workflows will become for everyday makers, but the technique underscores the unique design freedom that lattice-based 3D printing offers over traditional foam moulding.
