DOHO Corporation will exhibit at the "New Technology Creation Exchange 2025." We will showcase samples created with ZRapid's metal 3D printers (SUS, Al, maraging steel, Inconel, copper, titanium, and more) and will be available for consultations on the applications and specifications of metal 3D printing services. Please stop by booth A-34. Dates: October 23, 2025 (Thursday) 10:00–17:00 / October 24, 2025 (Friday) 10:00–16:00 Venue: Tokyo Tama Future Messe Official website: https://shingijyutsu-soushutsu.jp/ Pre-registration for visitors: https://shingijyutsu-soushutsu.jp/visitor/

Thank you for your continued support. This is the DOHO Equipment Team. Thank you very much for visiting the booth of our partner company, Sailong AM, at the "Monozukuri World Next Generation 3D Printer Exhibition" held at Makuhari Messe the other day, despite your busy schedule! At our booth, we introduced our 3D modeling services using electron beam technology, primarily focusing on pure copper, as well as a metal powder milling machine using the PREP method. We also displayed samples of pure copper coils, heat exchangers, and titanium and tantalum samples used in medical orthopedic implants! The metal 3D printer that produced the samples on display employs electron beam technology, enabling high-density and high-efficiency layered manufacturing, which provides solutions to various needs such as rapid prototyping, small-lot production, and accommodating special shapes. If you have any requests or questions that we could not address on the day of the event, or if you have any points of interest later on, please feel free to contact us using the link below. https://doho.co.jp/3dprint/contact/

Thank you for your continued support. This is DOHO Corporation. We would like to introduce our 3D modeling service! We have started offering 3D printing of copper and pure copper using the electron beam melting (EBM) method, known for its high melting point materials! Pure copper, which has challenges with reflectivity and thermal conductivity, can now be stably modeled with high density and precision using EBM. We can accommodate designs that were previously difficult, such as heat sinks, electrodes, and coils. This service has been made possible through our partnership with Sailong in China. We have a wealth of experience in mass production of pure copper, manufacturing over 20,000 automotive parts annually, showcasing our unmatched capabilities. 3D modeling of copper and pure copper ~ What is the electron beam method? ~ https://doho.co.jp/3dprint/3d-print-service-doho/basicinfo-10/ We also offer free consultations regarding metal 3D printers and 3D technology at any time. Please feel free to contact us! We will continue to strive to meet your expectations, so we kindly ask for your continued patronage. For inquiries, please visit https://doho.co.jp/3dprint/contact/

Our company DOHO (the domestic general agent for ZRapid) is collaborating with Inoue Boring, a company specializing in internal combustion machining, to manufacture the cylinder of the classic motorcycle "Mach III" using a metal 3D printer, and we are promoting a project aimed at practical application. The cylinder block is produced using ZRapid's SLM method metal 3D printer, with secondary processing and finishing handled by Inoue Boring. A cylinder has been completed that is comparable to genuine parts in both functionality and durability! Additionally, we have completed running tests at the Tsukuba Circuit, demonstrating the potential for practical parts manufacturing using AM technology. This project has been featured in the motorcycle specialty magazine "G Works Bike" as an innovative initiative in the classic car industry! DOHO supports the implementation of AM technology through equipment sales and contract manufacturing. We welcome inquiries at any time, so please feel free to contact us! ■Details and video https://doho.co.jp/3dprint/column/column-08/ ■DOHO Contact https://doho.co.jp/3dprint/contact/

We are pleased to announce that the 3D-printed cylinder from our joint project with Inoue Boring has been featured in a motorcycle specialty magazine. This product will also be showcased at JIMTOF in November 2024, drawing attention as a case study for the application of 3D printing technology to vintage motorcycle parts. The article is titled, "Testing 3D-Printed Cylinders on the Circuit - This Could Be a Revolution for Vintage Motorcycles," and it covers the background of the project, the manufacturing process, and the actual performance tests on the circuit. 3D printing is highly effective for the restoration and repair of vintage motorcycle parts, and we plan to expand its application to various other components in the future. Please feel free to contact us for inquiries regarding the introduction of metal 3D printers or our printing services.

DOHO Corporation offers a "Metal 3D Printing Service" aimed at promoting the use of metal 3D printers. In response to customer feedback, we have decided to expand our offerings. Additional materials available: pure copper, tungsten, titanium alloy 64, etc. *We are also considering further expansion of our service range in the future. Possible production range: approximately 160mm x 160mm x 200mm *We can also consider accommodating sizes outside of the above through separate discussions.

Notice of Participation in the "National Craftsmen's Skills Exhibition" DOHO Corporation will participate in the "National Craftsmen's Skills Exhibition" held on March 7 (Friday) at the Ota City Industrial Plaza PiO, continuing from last year. On that day, we plan to display samples made with a metal 3D printer and intricate puzzles created with an electrical discharge machine. ■ Exhibition Overview Date: March 7, 2025 (Friday) 11:00 AM - 5:00 PM Venue: Ota City Industrial Plaza PiO Booth Number: 48 ■ Exhibition Content Introduction of 3D modeling services Models produced with ZRapid's 3D printer No pre-registration required for visitors!
