Prototype development with 3D printing
Maxime Lallemand , Syncros components engineer at Scott , one of the major brand manufacturers in the bicycle industry , outlined : “ We have been working with Dangerholm for many years . This time , he wanted to produce a prototype of his idea of the bike of the future with us for Eurobike 2024 - not a design study , but a fully operational mountain bike . The new handlebar concept was also a particular challenge for us .”
The clock started ticking : there were five months until Eurobike in Frankfurt , Germany , for development , production on the TruPrint 3000 and ISO certification of the handlebars . So Scott developer , Maxime Lallemand , and Quentin Beauregard , MTB lead designer at Scott , used their contacts at TRUMPF to move the project forward .
“ For prototype development , aluminium 3D printing is unbeatable in terms of cost and speed compared to classic carbon / mould construction . Technically speaking , 3D printing pushes the boundaries in terms of form and function . This enables us to build a technically perfect handlebar for Gustav that eliminates all visual distractions ,” they said .
Maxime Lallemand and Quentin Beauregard had met application developers Chris Lengwenat and his colleague , Nicolas Haydt ( technology specialists in additive

manufacturing at TRUMPF ), at Eurobike in 2022 . In their luggage , Chris and Nicolas had a brake lever , a brake caliper and a pedal developed by them both and printed on a TruPrint 3D printer with aluminium and titanium .
“ We went from stand to stand with our small suitcase ,” recalled Lengwenat . Haydt added : “ By the end of the day , we had many new contacts in the development departments of a lot of major manufacturers , including Maxime Lallemand . He also introduced us to bike tuner , Dangerholm .”

In the run-up to Eurobike 2024 , the threads between TRUMPF , Scott and Dangerholm came together again .
