CoreLight3D®

• Lightness: for the same volume, far less material and far less weight than the solid polymers used by other large-format printing systems
• Stiffness where it matters: the fully customisable corrugated internal structure gives the part its stiffness; the external lamination does the rest
• Workability: it can be cut, sanded, filled and painted with the tools and products of an ordinary shipyard, like wood
• Bonding: optimised to bond with resins and composite laminates
• Toughness: damage-tolerant core that withstands repeated impacts and is easy to repair
• Recycled: up to 70% recycled content, near-zero printing waste

• Structural seat for a 43-foot catamaran: 37 kg, 42 print hours, presented at JEC 2026
• Living module for a Piaggio Ape: about 70 kg against roughly 200 kg for the fibreglass equivalent, over 4,500 km to Nordkapp through rain, 90 km/h gusts and temperatures from 30 °C down to 2 °C
• Press test: a printed sandwich panel takes 2 tonnes and springs back, where a solid wood beam snaps at 1.5. Watch the Breaking Rules video ›

These photos come from a partner shipyard specialising in catamarans, which laminated a CoreLight3D® printed element in fibreglass. The part was cut open to look inside, and the cross-section says it all: the printed core with its corrugated cells, the two fibreglass skins bonded above and below, a complete sandwich.

Anyone who works with composites sees the difference at once. The core is not a flat panel to be fitted into a mould: it is printed directly in the shape of the part, with the cells oriented where they are needed, and the skins bond to its surface without a gram of extra core. The result is a light, stiff and repeatable structure, obtained with no plug and no mould.
