Serendix Conducts Projectile Impact Test on 3D Printer Structures

Serendix Co., Ltd. (Headquarters: Nishinomiya City, Hyogo Prefecture, CEO: Hiroyasu Koma, hereinafter "Serendix") has conducted a projectile impact test targeting unique structures printed with its construction 3D printer and materials treated with special processing.

The experiment compared and verified the effects of differences in structural shape and material treatment on impact resistance. This release includes an experimental video capturing the process.

Experiment Overview

In this experiment, multiple structures printed with a construction 3D printer and materials treated with special processing were subjected to high-speed impact from metallic projectiles to compare and verify their impact resistance. As a result of the verification, clear differences in durability were confirmed due to variations in structural shape and processing methods, and useful data was acquired for research and development of structures requiring high protective performance.

Exhibition at "Farnborough International Airshow 2026"

Furthermore, our company will exhibit at "Farnborough International Airshow 2026," one of the world's largest aerospace and defense industry exhibitions, to be held in the UK from July 20th to 24th (within the Japan Ministry of Defense Equipment Booth). This exhibition aims to broadly promote the appeal and high technological capabilities of Japanese defense equipment in collaboration with the Ministry of Defense Equipment and industry-government efforts. From our company, we plan to exhibit a "3D Concrete Printing Blast Shelter" and a "Drone Base" that leverage the results of this experiment.

Comment from Kunida Iida, Co-founder and CTO

3D printer construction is characterized by its ability to freely create curved surfaces and complex wall shapes. Furthermore, by varying the number and configuration of walls according to the structure's intended use, applications are expected not only for housing but also for structures requiring high protective performance, such as disaster prevention and blast protection.

Our company has filed patent applications for manufacturing methods that optimize the number and structure of building walls according to their intended use, utilizing 3D concrete printing technology. Through this, we are advancing the development of structures with enhanced impact resistance and protective performance by combining features such as double and triple-layered walls, multi-layered structures utilizing ribs, and innovative material treatments.

Confirming that clear differences in impact resistance arise due to variations in structural shape and material treatment is a highly significant finding that broadens the possibilities of 3D printer construction beyond housing, including blast shelters, drone bases, public infrastructure, disaster response facilities, and reconstruction housing. We will also advance applications for rapid recovery and reconstruction during disasters or emergencies by leveraging the unique advantages of 3D printer construction, such as data acquisition of damaged areas and remanufacturing of components.

Through our participation in the Ministry of Defense Equipment booth, we will disseminate the potential of 3D concrete printing blast shelters and drone bases, and are proceeding with reconstruction projects in Ukraine in collaboration with local companies. Housing safety is the foundation for protecting people's lives and livelihoods. We will utilize the knowledge gained from this experiment to improve the safety of buildings, including reconstruction housing, and deliver safe and affordable housing to people worldwide.

About Serendix

Our company is Japan's first 3D printer housing manufacturer. Starting with "serendix10," Japan's first 3D printer house in March 2022, we constructed the first unit of "serendix50," a house for two-person households, as a reconstruction housing model in Suzu City, Ishikawa Prefecture, in September 2024. We are currently advancing a reconstruction support project in Ukraine using 3D printer construction, with designs supervised by Masayuki Sone (Clouds AO), an architect involved in NASA's Mars colonization project. In 2025, we will construct station buildings with the JR West Japan Group, with whom we have a capital and business alliance, and provide construction robotics solutions both domestically and internationally, extending beyond housing.
