High Resolution
How it works
Similar to stereolithography, the starting material is a liquid plastic resin. These liquid resins are photoreactive, which means they react with UV rays and harden. In contrast to many other additive manufacturing processes, we do not have a classic layer application in high-resolution printing, as in stereolithography. The basic principle is that the build platform is placed in a tank filled with resin from above. This means that the components are printed upside down. For the first layer, the build platform moves all the way down and then up a layer thickness. The liquid resin is distributed evenly underneath the building platform.
The UV projector now projects the component contours from below through a transparent membrane and cures the first layer. The platform then moves up again and the resin for the next layer can spread. This process is then repeated until all components have been printed. The build platform then moves completely out of the tank. This process also requires support structures to secure the component to the build platform. The finished printed components can now be removed, cleaned and removed from the supports. The process is considered to be one of the fastest in additive manufacturing.
Advantages of high-resolution 3D printing
High resolution printing can produce small components with extremely high-quality surfaces and the finest details. At the same time, the components are not only suitable for prototypes but are also designed for a long service life.
Extremely high resolution:
Thanks to the fine layers (selectable between 10-50 µm) and the high resolution of the 4K projector, breathtaking surfaces and the smallest details are displayed perfectly.
High Speed:
The printer produces components within a very short time. We can therefore offer delivery times of 2-3 days. And an express 24-hour service.
Long-term resistant:
Unlike many other technologies that work in a very similar way, the materials used in HR are particularly durable and resistant. In addition to prototypes, the entire process is designed to produce ready-to-use series parts.
High Resolution: The applications
The fast production of precise components, whether as individual parts or in series, is the field of application. HR printing really comes into its own when it comes to fine details and intricate geometries.
Materials
High Resolution offers a selection of UV and long-term resistant materials.

Postprocessing in HR
Due to the smooth injection-molded surfaces, reworking is usually not necessary, but is still possible.
