3D Printed Fixture Boosts Automotive Line Efficiency 65%

Background

An EV manufacturer needed frequent fixture changes for mixed-model assembly lines. Traditional CNC fixtures had long lead times and high costs.

Solution

• Carbon fiber reinforced PA12 (SLS) 3D printed fixtures
• Topology optimization for 45% weight reduction
• Integrated design, fewer assembly parts
• On-demand printing, no inventory needed

Results

• Lead time: 14 days → 2 days
• Unit cost: ¥5000 → ¥800 (84% reduction)
• Weight reduction: 45%
• Line changeover time: reduced 65%
