In-Vision introduces HELIOS, the most powerful DLP light engine for additive manufacturing

HELIOS Light Engine brings DLP-based 3D printing to the next level

(Vienna/Boston) In September 2020 the Austrian technology provider for 3D printing systems, In-Vision, will present the result of two years of research and development work. “The HELIOS light engine is a UV light projector for additive manufacturing that was specifically developed to achieve the highest illumination intensity to allow for faster prints and the use of highly reactive photopolymers”, says Christof Hieger, CTO of In-Vision.


In-Vision’s customers include many of the world’s leading manufacturers of 3D printers. “There has always been a high demand for more light intensity among our customers. However, we could not find an off-the shelf light source that could fulfil this need”, explains Hieger. “We knew we had a team who was able to come up with a great product, so we started our own development.”


HELIOS is based on In-Vision’s new proprietary light source and achieves 60W of illumination intensity, which is twice as much as what most light engines on the market can achieve. This results in more than 12W on the image plane according to the company. In addition, “all optical elements and their coatings have been optimized to offer higher uniformity and contrast ratios than any other system we benchmarked”, adds Gerold Aschinger, head of HELIOS development team.

In addition to the optical performance of Helios, In-Vision wanted to incorporate as many improvements for the customer as possible. “It has never been easier to operate and maintain a DLP light engine”, continues Aschinger. “The entire projector follows a modular design: it is fully built in sub-assemblies for highest accessibility and the LED module can be easily exchanged by the customer.” Furthermore, HELIOS will be available in customized pixel solutions and wavelengths. The current version is based on 385nm.


“With this product we want to contribute to even more cost-effective prints, allow for new materials and qualify additive manufacturing further for serial production applications”, says Hieger. The first customers in the United States and Asia have already begun with qualification tests. The product will be available in December for the public audience.
