[What is a 3D Printer?]
A 3D printer is an innovative manufacturing technology that creates three-dimensional objects based on digital data using various forming methods such as layering, photopolymerization, and powder sintering. Without the need for traditional processes such as cutting or mold fabrication, it can reproduce complex shapes in a short time, making it widely used in manufacturing, medical fields, robotics, and research and development.
In recent years, advances in material technology and printing accuracy have greatly expanded the range of available materials-now including not only resins but also metals, ceramics, and rubber‑like materials. Beyond accelerating prototyping, 3D printers enable cost reduction in development, creation of personalized products, experimentation with new mechanisms, and small‑lot/high‑mix production, offering value previously difficult to achieve with traditional manufacturing.
[What is Silicom — A New Technology for 3D Printing Real Silicone]
Hotty Polymer’s “Silicom” is a uniquely developed, Japan‑made 3D printer capable of forming objects using real silicone materials that feature high flexibility and heat resistance.
The biggest advantage is the ability to reproduce silicone’s inherent material properties softness, rebound characteristics, heat resistance, and weather resistance which cannot be achieved with general rubber‑like resins.

[Why Silicom is Chosen]
- High flexibility and heat resistance: delivers the performance required in medical and robotics fields
- Real silicone forming: provides functionality that rubber‑like resins cannot replace
- In‑house development, made in Japan: hardware and software fully developed by Hotty Polymer
- Reliable technical support: comprehensive support covering materials, forming, and application technologies
[Applications]
- Researchers requiring flexible models in medical and biological fields
- Engineers prototyping functional components such as robot hands and grippers
- Development teams needing small‑lot prototyping or evaluation of flexible materials
- Universities and research institutes conducting verification of new materials and mechanisms
[Examples of Printed Parts]
- Medical models (organ models, models for procedural training)
- Robot hand and flexible gripper components
- Functional prototype parts for advanced research (e.g., technology enabling detection of robot hand motion or missed gripping using flexible sensors that measure voltage change, contributing to automated packing of delicate foods)
- Small‑lot production parts requiring heat and weather resistance (e.g., heat‑resistant seals for heating devices, heat‑resistant buffer blocks for productionlines)

[About Hotty Polymer]
Hotty Polymer Co., Ltd. is a Japanese specialist manufacturer providing material development, product design, and processing technologies to a wide range of industries, based on its resin and rubber extrusion technologies. With many years of expertise in material compounding and precision forming, Hotty Polymer supplies high‑quality products that meet the demanding requirements of the medical, automotive, consumer electronics, and industrial equipment sectors.
Furthermore, Hotty Polymer is highly regarded in Japan as one of the few 3D printer manufacturers specializing in flexible materials and elastomers.
Even in Japan, practical examples of 3D printing with real silicone are rare, and nearly no companies develop domestically produced 3D printers capable of stably forming real silicone. This uniqueness has made Hotty Polymer a trusted partner, receiving continuous requests from:
- Major manufacturers’ prototyping divisions
- Medical research institutions
- Robotics companies
- National universities and engineering research institutes
With strong technological capabilities in the field of flexible materials, Hotty Polymer is recognized as one of Japan’s leading companies. The company actively pursues the development of unique technologies such as Silicom and fulfills its role as a “technical partner” that supports customers’ problem‑solving and value creation.
As professionals in silicone materials and forming technologies, Hotty Polymer strongly supports customers' development activities.
