A honeycomb structure that achieves a fine lattice exceeding 10,000 cells/in². It can be transported without deforming the shape of thin materials (such as paper and film)!

Micro-honeycomb is a honeycomb structure that achieves a fine lattice of over 10,000 cells/in². The honeycomb structure is arranged without gaps in a shape resembling hexagonal prisms, and can be likened to mesh, grids, or the eyes of a dragonfly. Because it is hollow inside, it can create lightweight yet strong materials. In addition to being able to form integrated pieces over 200mm, it is also possible to impart functions through materials such as black materials and electrostatic discharge materials. By attaching micro-honeycomb to the suction head, it serves as a filter, allowing for the transportation of delicate parts and thin film materials that are prone to deformation while maintaining their shape. It is also possible to transport cut films measuring 1cm square. [Applications as a suction head] - Transportation of thin film materials that are prone to deformation - Transportation of paper that is prone to wrinkling - Fibers - Transportation of fine precision parts For other applications, please feel free to contact us. *For more details, please refer to the PDF document or feel free to reach out to us.

Metal 3D printers are becoming increasingly diverse, with relatively affordable low-cost machines available for several tens of millions of yen, as well as binder jetting technology that enables mass production of parts. High-speed, large-scale machines for creating large components and products are continuously being introduced to the market. Furthermore, the prototyping of magnesium parts and the manufacturing of copper components, which were difficult to produce with existing technologies, have begun. Metal 3D printers eliminate the need for molds by allowing products to be created directly from 3D data. They enable the creation of complex shapes that were impossible with traditional processing methods, as well as lattice and porous structures, hollow structures, and hybrid structures. This leads to the innovative creation of metal parts and molds that are not available from conventional sources, significant reductions in prototyping and manufacturing time, drastic decreases in the number of parts, lightweight miniaturization, and reductions in manufacturing processes and workforce. Using metal 3D printers, we provide easy 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. 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.

In this seminar, we will briefly explain various molding methods and technologies for plastic molds using metal 3D printers, key points and considerations in manufacturing, and examples of molding. Following this, advanced users utilizing metal 3D printers from EOS, 3D Systems, Sodick, and Matsuura Machinery will discuss cutting-edge mold manufacturing technologies and cases, as well as the factors behind failures and secrets to success. First, we will explain molding cases that have achieved low-cost, high-quality manufacturing techniques and shortened lead times through complex shapes and integrated molding, hybrid molding, and 3D cooling water pipe molding using EOS metal 3D printers at J-3D. Next, we will discuss ODEC's achievements in drastically reducing lead times and costs in mold updates by manufacturing complex molds for resin molding with metal 3D printers, as well as the latest molding cases and simulation technologies for internal structures (3D water pipes), water flow, and temperature. Finally, we will provide specific explanations of Sanko Gosei, the industry leader in plastic mold manufacturing technology using metal 3D printers, including remarkable reductions in mold cooling times through 3D cooling water pipe molding, and how porous molding effectively suppresses and prevents defects and troubles such as short shots and gas burns, along with examples of reduced injection times.

The complex shape modeling, integrated modeling, lattice/honeycomb structure modeling, porous structure modeling, hybrid structure modeling, direct modeling from 3D data, as well as topology optimization and collaboration with generative design, which were difficult with conventional processing methods and technologies, can lead to the creation of innovative aluminum parts that are not available from traditional or other companies. This includes rapid development, prototyping, and modeling of parts, dramatic reductions in the number of parts, ultra-lightweight and compact designs, and significant reductions in costs, manufacturing time, number of processes, and workforce. In this seminar, pioneering users such as J.3D, ODEC, and the pioneers of white copper, who are utilizing metal 3D printers to rapidly develop, prototype, and manufacture complex aluminum parts, will provide specific explanations on key points and precautions for implementation and utilization, various modeling methods and technologies, unique next-generation AM technologies developed in-house, and groundbreaking modeling examples that significantly differentiate from other companies, sharing both success and failure stories. With the remarkable advancements in metal AM technology, the use of metal 3D printers for aluminum part modeling and manufacturing will become commonplace in a few years. The secrets to success will be explained in an easy-to-understand and concrete manner by instructors with numerous research achievements and extensive modeling experience, aimed at those considering implementation, beginners with interest, and those who are new to the field.
