Composites, recycled materials, technical textiles 2-4 Mar 2027, Paris Nord Villepinte 45,000 attendees
The global composites industry tradeshow, run by JEC Group, covering the full value chain from raw fibre to finished part across aerospace, automotive, wind and construction. The reference event for the vertical.
Why it is hereThe largest and most established composites-industry gathering anywhere – every serious European materials company exhibits or attends.

AM software, bio-based materials, metal and polymer 3D printing 17-20 Nov 2026, Messe Frankfurt 38,282 attendees
Mesago Messe Frankfurt's additive manufacturing show, the largest dedicated 3D printing event in the world. Shared with the Additive manufacturing vertical, with strong new-materials programming for print feedstocks.
Why it is hereThe materials science that feeds 3D printing – metal powders, polymers, bio-based feedstocks – gets its deepest European showcase here.
3Rank
Composites 4 Mar 2027, Paris Nord Villepinte Attendance not published
A dedicated investor day co-run by JEC Group and Sesamers, held alongside JEC World, connecting composites founders directly with the capital markets attending the main show.
Why it is hereThe one event on this desk built specifically for investor introductions rather than trade exhibition – and it is co-organised by Sesamers itself.
Attendance figures come from each event’s own record and organiser statements. JEC Investor Day runs on the same day as JEC World’s opening, in the same venue – the two are designed to be attended together. Only three events carry this tag; the calendar is thin outside these two anchor shows.
