To construction and civil engineering companies looking for the "next" step in digitalization. This seminar will explain the currently trending topic of "AI utilization" in 45 minutes. We will clearly introduce the latest trends, specific case studies, and steps for implementation to address questions such as "What can AI do?" and "How can it be applied to our business?" Whether your company is already advancing in DX or is just starting to consider AI, you will find hints for improving operational efficiency. 【Schedule】 1: Company introduction and instructor introduction 2: Case studies of AI utilization in the construction and civil engineering industry 3: Convincing examples! Patterns of AI utilization in construction operations 4: Three steps to avoid failure in AI implementation 5: Q&A and closing remarks

We will address the issue of young employees who, despite joining the company, leave due to reasons such as "there's no time to be taught," "I don't understand when I'm told to learn by watching," and "what is written and said varies depending on the project or person in charge." We propose a system that accumulates the know-how of veterans in AI and systems, allowing young employees to search for and solve problems on their own. 【Schedule】 1: Company introduction and instructor introduction 2: Reasons why technical inheritance is not progressing (lack of time, difficulty in verbalizing) 3: "Next-generation manual and know-how sharing methods" utilizing video and AI search 4: Examples of system construction to institutionalize technical inheritance 5: Q&A and closing remarks

Metal 3D printers are becoming increasingly diverse, and recently, relatively affordable low-cost machines costing several million yen, binder jetting methods that enable mass production of parts, and high-speed, large machines for creating large components and products have been continuously introduced to the market. Furthermore, the prototyping of magnesium parts and the manufacturing of copper parts, which were difficult to create with existing machines, have begun. Metal 3D printers eliminate the need for molds by directly producing products from 3D data, and they can create complex shapes that were impossible with traditional processing methods, as well as lattice and porous structures, hollow structures, and hybrid structures. This enables the innovative creation of metal parts and molds that are not available from conventional or other companies, significantly reduces prototyping and manufacturing time, drastically decreases the number of parts, allows for lightweight and compact designs, and reduces manufacturing processes and workforce requirements. Using metal 3D printers, we provide easy-to-understand explanations for those considering the development of attractive new products, the creation of new businesses, differentiation from existing products, significant reductions in prototyping and manufacturing time, dramatic decreases in the number of parts, and cost-effective lightweight complex-shaped components, as well as for beginners who are interested in these topics. The world is energetically investing in metal parts and mold manufacturing as the leading candidate for the next generation, and mass production of parts has also begun in earnest. Manufacturing parts with metal 3D printers will become commonplace in a few years.
