Dan Fritsche of <a href="https://www.instagram.com/3d_coasters/" class="on">3D_coasters</a> spent over 6 months to design, 3D print, and assemble the world's first functional 3D printed roller coaster. The 1:35 scale model is controlled via an Arduino with 5 micro servo motors and 1 DC motor.#RollerCoaster #3DPrinting #DanFritsche #ScaleModelView the full YouTube video clip:

Fritsche explained in the video clip that the roller coaster model was made with 2,983 individual parts (the train alone was 410 individual parts), and it took over 800 hours to 3D print and 7 rolls of filament. The model weighed 30 lbs (13 kg).
