Training Models

Yasojima can create realistic, accurate, and versatile models with multi-material 3D printing technology. Using real patient data, DICOM (Digital Imaging and Communications in Medicine) data, 3D printed medical models can effectively simulate everything from soft tissue and muscles to cartilage and bone, including subtle visual and tactile details, in a single print job. Realistic anatomical models can be extensively customized to prepare physicians and surgeons for almost any clinical scenario.

Endoscopy Training Model

Yasojima Proceed can produce synthetic endoscopy training models for both upper and lower gastrointestinal tracts (ERCP, EST, EUS, FNA, etc.). Our realistic designs help develop and enhance the skills necessary to perform certain medical procedures.

We can define what mechanical and physical properties are key and propose the most suitable machining and 3D printing materials to meet your requirements, such as electric graduated incision, slipperiness, and ultrasonic transmission to help build the confidence needed to perform successful endoscopic procedures.

Silicon/urethane molded.  Electric scalpel training can be performed on PVA molded parts utilizing our exclusive in-house developed material which closely resembles living tissue.

Procedural Training Board

Compact and portable Laparoscopic Virtual Endo Trainer Kit.

The 3D printing process allowed us to reduce the number of individual parts used as it is able to produce smaller parts and components with complex and intricate designs. It is also ideal for low production end-use parts and applications. In terms of functionality, this compact and portable trainer kit allows for numerous choices in port setting and comes with a slim and robust attachment.

Bone Model (Japan Custom Bone)

Yasojima can produce bone models of all sizes including synthetic cortical and cancellous bones. Customized models are also available for medical professionals who require realistic and reliable 3D printed anatomical models for use in surgical training and simulation.

Echo-guided Puncture Simulator (Echo Shot)

Echo Shot, exclusive to Yasojima, can replicate the feel and characteristics of needle punctures and insertions to blood vessels and subcutaneous tissue. Results can be inspected as the material is transparent. The simulator is compact and easy to handle, it remains stable over time, and is non-hardening.

Microneedle Port Puncture Training Model

Used in training for needle puncture and surgical insertion of Totally Implantable Central Venous Ports (TICVP) through infraclavicular subclavian and internal jugular venous access.

Axillary Level 1 3D Model

A three-dimensional axillary surgical simulator designed and introduced in “Axillary dissection visual text that can be easily understood with a 3D model,” a textbook by Dr. Kyoko Mantani. Ready-to-train model for axillary lymph node dissection.

Plastic Materials for Surgical Training Models

Various materials can be selected according to the application and purpose.

3D modeling can be performed using DICOM data. The data is used to create mold masters and model bodies making it possible to create realistic and original models.


Yasojima has a wealth of experiences producing blood flow simulation models.

Hardness: Shore A 0°~95° that range in hardness from very soft and flexible to imitate human skin, somewhat flexible, to hard.

Color: Highly transparent and can be colored to match a color sample.

Suture practice model

PVA (Polyvinyl alcohol)

PVA is a water-soluble and biocompatible material that can be used in applications that require a material which shares the characteristics of human skin and tissue. It is suitable for incision training using a high-frequency electric scalpel. The hardness of PVA can be customized and multi-layered structural sheets are also available.

Standard size sheets (100 x 100 x 2-10mm) are also available.

Application: Large intestine model

Skin model

Nylon 12/Ultem 1010 (3D printing)

Hard plastic materials such as Nylon 12 and Ultem are compatible with autoclave sterilization and have biocompatibility ISO10993/USP Class VI. They can be used for making parts such as bone models and attachments for training units.

Femur model


Materials with high elongation rates. Mass production of parts with this material is also possible using injection molds.

Stomach model

Others (Film, sponge, etc.)

Yasojima can use a variety of other special grade materials to produce models of blood vessels and other membranes.
