NIU Electric Scooter Large-Format Engineering-Grade Integrated Lightweight Cockpit
Integrated PET-CF Lightweight Cockpit Rapid Prototype Validation and Industrial Application Case
Abstract
In the field of electric mobility innovation, speed is key to success. This case study demonstrates how the CreatBot D1000 HS industrial 3D printer collaborated with NIU electric scooters to breakthrough traditional manufacturing bottlenecks: just 65 hours a **750mm long integrated PET-CF carbon fiber cockpit shell, was printed in one piece inweighing only 2.4k. This successfully achieved mold-free, high-strength, rapid iteration prototype validation, setting a new benchmark of "combining speed and performance" for the R&D of large functional components.
Industry Background and Challenges
In the electric vehicle innovation sector, product iteration speed and customization capability have become key metrics for measuring a company's core competitiveness. NIU electric scooters, as an industry technology leader, needed to create 1:1 functional prototypes for real vehicle testing and user research to validate the structural integrity, ergonomic adaptability, and aerodynamic performance of a new generation intelligent cockpit system. However, they faced the following common industry challenges:
• R&D Cycle Pressure: Traditional mold manufacturing cycles take months, unable to meet the market demand for rapid iteration
• Customization Needs: Personalized demands for model configurations are increasing across
global markets
• Cost Control: Mold opening costs are high, posing significant risks, especially during the
prototype validation phase
• Global Collaboration: Required synchronized development and data sharing across
transcontinental R&D centers
