important, technologies for inspection and material restoration are especially important for products for which material deterioration significantly affects the product
performance and reliabilities. Such products include those in aerospace, HDOR,
machinery, and automobile parts sectors.
Hence, this study investigated material restoration processes in remanufacturing,
focusing on the conduct of a survey of AM techniques in these processes. Surveys in
the industry were mainly targeted at the sectors of aerospace, HDOR, and automobile
parts.
36.3 Conventional Additive Manufacturing Techniques
Used in Remanufacturing
36.3.1 Survey Method
To investigate the material restoration processes in present remanufacturing, an
author visited and interviewed nine firms to survey the process. Most of the firms
were Japan-based companies. The product areas included: automobile parts, HDOR,
aerospace, machinery, and power-generating facilities.
36.3.2 Application Cases
Oftentimes after usage of a product, the components incur surface damages. In some
cases, the damages can be restored by scraping off the damaged part, a method categorized under subtractive manufacturing. Nonetheless, the technique is applicable
