Signs】https://yamaichi-hagane.jp/wp/?p=5242 An era in which
three-dimensional objects must combine design and safety In the sign and display industry, design and safety are now more important than ever. This is because disasters such as earthquakes have raised awareness of the importance of safety measures to prevent falling and tipping accidents, as well as designs that ensure visibility during power outages and other disruptions. However, conventional materials had their limitations. Acrylic, which has been widely used for signs, has issues such as being heavy, easily breakable, and dangerous when damaged. Wooden and metal objects also pose concerns about
installation and safety due to their weight. Signs and objects are often installed overhead or near pedestrian traffic, making it essential to balance lightweight design with safety. In light of this, Yamaichi Special Steel offers a new, groundbreaking option by combining a resin 3D printer with painting and laser processing. Innovation brought about by 3D resin signs and objects ●Improved safety through reduced weight For signs and objects where weight was an issue, using a resin 3D printer can reduce the weight to less than half that of acrylic resin, achieving significant weight reductions compared to wooden and metal objects. This ensures safety while also contributing to the efficiency of installation and construction. ●Enhanced design through freedom of design Soft curves and
three-dimensional expressions that previously could only be reproduced by hand by artisans can now be reproduced with high precision and stability by using 3D printers, painting, and laser technology. We can freely create complex shapes, metallic finishes, and large objects, providing a wide range of designs with consistent quality, from guide signs in commercial facilities to three-dimensional objects at event venues. ●Reproducibility and technology transfer through
digitalization For many years, the production of three-dimensional objects has relied on the experience and intuition of skilled craftsmen, but by introducing a data-based design and modeling process, we have moved away from reliance on individuals. This enables a mass production system with reduced quality variation, while at the same time preventing technological discontinuity through digitization, enabling the succession of knowledge to the next generation and realizing sustainable manufacturing. Yamaichi Special Steel’s technology evolves three-dimensional design 【1】From 3D Scanning to Freeform Modeling By accurately digitizing complex shapes with a 3D scanner and then printing them to any size with a 3D printer, it is now possible to digitally reproduce expressions that previously relied on artisanal skill. Even delicate shapes like a wooden carved bear can be reproduced with consistent quality, making this technology useful in a wide range of fields, from restoring cultural assets to display decorations.

Furthermore, by combining painting and laser processing, a variety of textures, including metallic, woodgrain, and marble finishes, can be faithfully reproduced, greatly expanding the freedom of design.

Ideal for signs and objects in public and commercial facilities, it helps reduce maintenance costs. In addition, by combining relief printing, the texture expression is enhanced in three dimensions, allowing you to reproduce your ideal design in high resolution.

(It measures 40cm in diameter and 5cm in height, weighing approximately 1.1kg, making it extremely lightweight compared to the real thing.) 【4】The Fusion of Design and Functionality Yoshida Advertising Co., Ltd. planned and designed original functional signs, which were then manufactured using Yamaichi Special Steel’s molding technology. This collaborative product, which combines smooth curves with ease of installation, will be presented to visitors as a new example of how design and practicality can be combined.
