SYGLASS – 3D printer for low-temperature glass

Groundbreaking technology for automated production of gradient optical components

SYGLASS are experts in manufacturing gradient optical components using proprietary technology.


We believe SYGLASS is a long-awaited step forward in the creation and development of new technologies that will usher in an industrial revolution in the fiber optics market.


We want SYGLASS to become a manufacturer of highly specialized optical components.


We aim for SYGLASS to become part of a larger company within 10 years, that will be a pioneer in the photonics market.

Major barriers to global photonics development:
  • High cost and long production time of preforms due to manual and multi-step production process
  • High risk of human error
  • Non-scalability of current production methods
  • Low availability and growing demand for nanostructured/special preforms
  • Large surplus of concepts/theoretical work over tested hypotheses
  • Fiber and lens manufacturing methods have reached the limitations of current manufacturing methods in terms of bandwidth and light shaping and transmission range
"Bottleneck" of the development of advanced photonics:


Lack of automation in the production of photonic components

Stagnation in photonics development

Limitations of healthcare development

Limitations of communication systems development

Limitations of cyber security development



Direct Ink Wrinting (DIW) 3D printing technology with a dedicated 3D printer that automates the process of creating preforms by directly extruding molten glass according to a programmed pattern.


  1. Loading the preform pattern and setting parameters
  2. Preparing and warming up the machine
  3. 3D printing of the preform
  4. Cool down
  5. The preform is ready!


The SYGLASS technology is based on groundbreaking research into the structuring properties of glass. Thanks to them, it was possible to create the first affordable technology allowing to automate the process of manufacturing nanostructured preforms using 3D printing from glass.

The developed prototype makes it possible to produce fiber optic preforms according to a preset pattern made of two different types of glass, which opens up possibilities for a wide range of applications previously unattainable.

By automating the process, SYGLASS technology replaces at least 6 industrial machines.

Paweł Wiencław

He joined Sygnis in 2021 as one of the R&D engineers and a few months later became a technology leader at SYGLASS. Since then, he has led SYGLASS to a higher level of maturity – both in the technological and organizational terms. He is also responsible for building relationships with potential customers and partners.
