Metal 3D printing technology is playing an increasingly important role in automotive and component manufacturing. It enables automotive companies to accelerate research and prototyping and aims to achieve high-quality series production in a timely manner. BLT uses its expertise in technological research and development to provide the automotive industry with high-quality 3D printed products and services, particularly in the areas of pre-research, production support and innovative design.
BLT has produced key components for the Tongji Electric Car Team’s DRe23 formula race car, including pillars, rocker arms, flange ear pieces and water-cooled motor housings. Using a generative design approach and AI tools, these components are optimized from a high-strength aluminum alloy and mass-produced on the BLT-S400 printing machine. The final parts meet strict mechanical requirements and achieve maximum lightweight construction.
For a Jeep model, BLT quickly validates the assembly and aesthetic effects. The model includes more than ten components with an average body thickness of 2mm. The roof and interior seats use a lightweight lattice structure, while elements such as wheels and doors integrate parametric textures for the production of complex configurations.
The BLT-A400 printing machine, equipped with five lasers, produces a complete substrate of 1004 car tire steel plates in just 52.2 hours, enabling an annual output of over 110,000 units. The finished steel plates have a precise size accuracy of ±0.05 mm, with a surface roughness of Ra3.2 to 6.3.
