DOHO List of Products and Services

We would like to introduce the manufacturing process and test results of the classic car cylinder project jointly developed by Inoue Boring and our company, DOHO. Using a printer from ZRapid, we created a high-precision product through secondary processing and sleeve insertion. It garnered attention at JIMTOF2024, where it was displayed alongside Mach III. The running tests at Tsukuba Circuit also received high praise. This initiative offers a new option for the revival of discontinued car parts through metal 3D printing, which can accommodate single pieces without the need for molds. We have achieved both the reproduction of complex shapes and durability, and we will continue to expand into a wider variety of parts in the future. ▼For more details https://doho.co.jp/3dprint/ https://youtu.be/dGFH9bdqUJM?si=Nwg5DTTM4jBKRv66

We spoke with the person in charge who was involved in the introduction of the large metal 3D printer "iSLM420DN" and a series of accompanying equipment. It was felt that future growth would be difficult to anticipate with existing methods such as processing and assembly, and there was a fundamental desire to aim for "strong" manufacturing while exploring future possibilities. The focus turned to a new processing method called additive manufacturing technology. Initially, there was no knowledge or know-how regarding 3D printers, so we began by researching 3D printer manufacturers, user companies, and universities that study 3D modeling technology. *Details of the interview can be viewed through the related link.

In dialysis treatment, the pain caused by puncturing with a needle as thick as a ballpoint pen is considered a major issue, and efforts have been made for some time to achieve "painless punctures" through ongoing research. Although technology has advanced, there is still room to reduce pain, focusing on the shape of the injection needle. For several years, we have been exploring manufacturing methods to realize an unprecedented special shape for the injection needle. The conventional manufacturing methods did not yield the ideal shape, leading us to consider production using a 3D printer, and we were contacted by your company. We spoke with the person in charge to understand the background of this initiative and how our company responded. *For detailed content of the interview, please refer to the related link.

Introducing SLM, which uses a laser as the heat source in the powder bed method, a mainstream technology in metal 3D printing. The powder bed fusion (PBF) method involves irradiating a layer of metal powder with a beam of light, causing it to sinter through the heat generated. By repeatedly melting and solidifying layer by layer, it creates a three-dimensional structure. While there are various fabrication methods, this one has a long history and is widely used. The powder bed method is divided into "Selective Laser Melting (SLM)" and "Electron Beam Melting (EBM)" based on the type of heat source used. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

• 3D Printer

This time, we will introduce the "design" process within the flow of 3D modeling. To create a model with a 3D printer, 3D data is necessary. In general modeling services, it is assumed that the client provides the 3D data. However, even if you do not have 3D data, we can create data from 2D drawings and also generate data through 3D scanning. After creating the 3D data, we will examine the modeling posture and make dimensional adjustments according to secondary processing using 3D CAD software, and design the support. After that, we will create the slicing data using slicing software. *You can view the detailed content of the column through the related links. For more information, please feel free to contact us.

• 3D Printer

This time, we will introduce the "preparation" process in the flow of 3D modeling. In the SLM method, where a laser is irradiated on a layer of metal powder, repeating melting and solidifying to build up layers, it is important to use high-quality metal powder. We offer five types of metal powders in our modeling services. We are also expanding our lineup through our network with ZRapid and partner companies, including materials not handled by 3D Factory. *For more details on the column, you can view it through the related links. Please feel free to contact us for more information.

• 3D Printer

This time, we will introduce the "modeling" process within the flow of 3D printing. Once the 3D data design and the preparation of materials and equipment are complete, the modeling can finally begin. We will also introduce the final confirmation work before operation. We check the sliced data read by the 3D printer and determine the layout of the products to be modeled on the substrate. By arranging them efficiently, many products can be modeled at once. Once this task is completed, the final modeling time will be confirmed. *For more details on the column, please refer to the related links. If you have any questions, feel free to contact us.

• 3D Printer

Metal powders have different characteristics depending on the manufacturing method. The properties of metal powders suitable for 3D printers are as follows: ■ High fluidity ■ High sphericity ■ Low oxygen content ■ No variation in particle size ■ Minimal presence of attachments known as satellites In the typical powder bed method of metal 3D printers, it is necessary to evenly spread the powder on the substrate, making high fluidity important. Additionally, it is crucial to minimize gas entrapment (including oxygen) as it can affect the finish, such as creating cavities inside the printed object. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.*

• 3D Printer

This time, we will introduce the "post-processing" step in the flow of 3D modeling. After the modeling is complete, excess metal powder is removed, and the model is separated from the substrate. As a finishing touch, a blast treatment is applied. (For some models, heat treatment is performed before separating from the substrate.) Excess metal powder on the substrate is collected using the attached suction nozzle. The collected metal powder is sent to the powder module for reuse. *For more details on the column, please refer to the related links. If you have any questions, feel free to contact us.

Our 3D business factory is equipped with metal 3D printers and associated equipment from ZRapid Corporation. We will introduce the discharge cutting machine and other equipment used to separate the printed objects from the substrate. Electrical discharge machining involves creating sparks by discharging between the workpiece and the electrode (machining tool), repeatedly melting, cooling, and dispersing the metal surface to process the metal. The discharge phenomenon occurs by applying voltage to the electrode, breaking the insulation in the gap between the two. As long as the material conducts electricity, it can be processed regardless of hardness, and since there is no physical contact between the workpiece and the machining tool, it places less strain on the materials, making it less likely to produce burrs on the cutting surface. Complex shapes that cannot be achieved through cutting can be processed with high precision. *For more detailed information, please refer to the related links. For further inquiries, please feel free to contact us.

I visited the new office (showroom and development base) of ZRapid, which opened in December 2022. At the entrance of the showroom, there is a management philosophy quoted from Laozi's "Tao Te Ching," stating: "Even a high platform of nine layers starts with piling up small earth, and a journey of a thousand miles begins with a single step." This conveys the meaning that "for any major undertaking, it is essential to steadily make efforts starting from what can be done now."
