How spectroplast is leading the charge in silicon 3D printing


Silicone has long been considered a difficult material to integrate into industrial applications due to its complex chemical and physical properties. However, advancements in additive manufacturing (AM) have ushered in a new era, with companies like Spectroplast leading the charge.


The Rise of Spectroplast in Silicone 3D Printing


Founded in 2017 as a spin-out from ETH Zurich, Swiss-based Spectroplast has carved out a niche by focusing on one of the most challenging materials for additive manufacturing: silicone. The company’s patented Silicone Additive Manufacturing Platform is a game-changer, making high-precision silicone 3D printing a viable option for industries ranging from medical technology to consumer electronics.


Recently, Spectroplast announced the completion of its Series A financing round led by HZG Group, with additional support from existing investor AM Ventures. Although the funding amount remains undisclosed, this capital infusion will enable Spectroplast to expand its patented materials into new industries, strengthen customer relationships, and address the growing demand for customized manufacturing solutions.


Silicone: A Material with Untapped Potential


Silicone offers unparalleled benefits for various applications, including its biocompatibility, resistance to temperature fluctuations, and durability. However, its properties have historically made it challenging to process using traditional manufacturing methods.


With Spectroplast’s use of cutting-edge technologies such as Stereolithography (SLA) and Digital Light Processing (DLP), silicone is now more accessible for industrial applications. These technologies enable the production of highly intricate parts with exceptional precision.


Dr. Pablo Hafner, Chair of Spectroplast, highlighted the company’s mission:


> “With Spectroplast, customers can have their first component in just a few days. We plan to significantly expand our product ranges in the future and offer completely new solutions for the most demanding applications. The fresh capital will help us achieve our goal of becoming a global leader in the 3D printable silicone industry.”

Pioneering the Future of Silicone Additive Manufacturing


Spectroplast’s success is part of a larger movement toward integrating silicone into additive manufacturing, akin to the earlier incorporation of metal into AM processes.


Dr. Florian Bechmann, CTO of HZG Group, emphasized silicone’s unique properties:


> “Silicone’s chemical structure makes it particularly suitable for additive manufacturing. Its biocompatibility and resilience against environmental factors position it as a versatile material for diverse applications.”




The company’s earlier seed funding round in 2018 raised approximately €1.38 million (around $1.48 million), laying the groundwork for scaling its production capabilities. Since then, Spectroplast has grown significantly, collaborating with customers to develop tailored solutions and expanding its product offerings.
