Overview

Glassomer is a German precision glass manufacturer based near Freiburg im Breisgau, in the Black Forest region. The company was founded in 2018 in Karlsruhe and later moved to Freiburg im Breisgau, where it established production of 3D printing resins and small-series glass parts. It describes itself as a constantly growing team of scientists, financial and sales experts, production and quality managers working on what it calls the glass technology of the future. Glassomer's core proposition is a proprietary process — the Glassomer Technology — that allows fused silica glass to be shaped at room temperature using standard industrial technologies such as injection molding and 3D printing. According to the company, this opens new design spaces for high-purity fused silica components with previously unseen designs and shapes. The company highlights exceptional material properties paired with high precision, complex shaping options and economical production, and lists durability, high purity, precision, transparency, recyclability and complex shapes as key benefits of its components. Glassomer positions itself as a print and media provider for unique and industrial-scale fused silica components, serving customers around the world. Its stated markets include optics, lab-on-a-chip and microfluidics, solartech and medtech. In optics, it offers special designs as well as micro- and nanostructures intended to increase optical performance and enable novel applications for illumination and imaging, available off-the-shelf and on-demand. In lab-on-a-chip, it provides complex chip designs in high-quality glass for chemical synthesis and high-throughput screening. In solartech, its process enables micro- and nanostructured glass surfaces that can reduce reflection losses in solar cells. In medtech, it emphasizes glass quality and ion leaching properties. The company reports that its technology has received multiple awards and has been reviewed and approved by leading scientific experts, with publications in Nature and Science. It also states that it holds several patents protecting its technology. Glassomer's history page records key milestones: founding in Karlsruhe in 2018, the move to Freiburg im Breisgau in 2018, the invention and patenting of the world's first process for injection molding of transparent glass in 2020, publication of the Glassomer process in Science in 2021, and a move to new production facilities in Freiburg in 2022. Glassomer is a private company. It presents itself in the spirit of the startup movement, emphasizing flexibility, innovation based on science, and precision and craftsmanship. Its mission is framed around building the glass production of the future with unlimited designs of high-quality glasses produced with lower energy consumption, contributing to the sustainability goals of modern production.

History

Glassomer was founded in 2018 in Karlsruhe, Germany, emerging from scientific research. According to the company's own history, its roots are in science, and it describes itself as working on a new tradition in glass making based on scientific breakthrough discoveries. In the same year, 2018, Glassomer moved to Freiburg im Breisgau and began production of 3D printing resins and small-series glass parts. In 2020, the company reports that it invented and patented the worldwide first process for injection molding of transparent glass. This was a significant technical milestone, as conventional glass shaping typically requires high temperatures, whereas Glassomer's process allows shaping at room temperature using standard technologies such as injection molding or 3D printing. In 2021, the Glassomer process was published in Science, one of the world's most prestigious scientific journals. The company states that its technology has also been published in Nature and reviewed and approved by leading scientific experts, and that it holds several patents protecting its technology. In 2022, Glassomer moved to a new production site in Freiburg, expanding its production facilities. The company describes itself as a constantly growing team of scientists, financial and sales experts, production and quality managers. It operates in the heart of the Black Forest and produces, shapes and processes its Glassomer materials according to high production standards. Glassomer's mission is to build the glass production of the future, with unlimited designs of high-quality glasses produced with lower energy consumption. It believes that glass was crucial for the information age, is crucial for industry 4.0, and will be crucial for emerging technologies. The company aims to forward markets such as optics, data technology, medtech and solartech while contributing to the sustainability goals of modern production. It positions itself as a print and media provider for unique and industrial-scale fused silica components, serving customers around the world with high-purity fused silica glass parts of previously unseen designs and shapes.
