Silicone 3D printing has long faced challenges in achieving high precision due to its unique material properties. However, the patent application "Ultra-low interfacial tension support medium for high precision silicone 3D printing" (US20230119492A1) introduces a novel solution to these problems. In this blog post, we will delve into a few technical aspects of this work and explore its implications for the future of silicone 3D printing.

Overview of the Patent Application:

The patent application US20230119492A1 presents a novel support medium for silicone 3D printing, characterized by ultra-low interfacial tension. This innovative support medium enhances the precision and quality of printed silicone parts, overcoming the limitations of conventional methods in achieving intricate geometries and complex designs.

The Science Behind Ultra-Low Interfacial Tension:

Interfacial tension refers to the force that exists at the boundary between two immiscible liquids, such as silicone and its support medium. By reducing interfacial tension, the support medium in the patent allows for smoother transitions between layers and minimizes defects in the printed silicone parts. This results in higher precision and improved surface quality in the final product.

Key Components of the Invention:

The support medium described in the patent is composed of a liquid mixture containing a surfactant and an organic solvent. The surfactant, which is a surface-active agent, is responsible for reducing the interfacial tension between the support medium and the silicone material. The organic solvent, on the other hand, ensures that the support medium remains in a liquid state during the printing process, enabling easy removal after the part is completed.

Advantages and Applications of High Precision Silicone 3D Printing:

The ultra-low interfacial tension support medium introduced in the patent application offers several benefits for silicone 3D printing. For instance, the improved precision and surface quality enables the creation of complex parts with intricate geometries, which were previously challenging to produce using traditional methods. This breakthrough technology opens up new possibilities in various industries, including medical devices, automotive components, and consumer products.


The patent application US20230119492A1 provides an advancement in the field of silicone 3D printing, if viable, offering a novel solution to the longstanding challenges of achieving high precision and intricate designs. With the introduction of the ultra-low interfacial tension support medium, the future of silicone 3D printing holds immense potential for various industries and applications. Keep an eye on this space for further developments and innovations in the world of additive manufacturing.
