xolography [ksəˈlɒɡɹəfi], noun

Meaning: Volumetric 3D materializing technology based on dual color photoinitiators

 Follow the Light

  • Tap for details


A video of slice images obtained from the 3D model to be created is displayed and focused into the lightsheet. The projector emits visible light and maintains the focus while the container moves away from the projector.

The resolution in x and y direction is determined by the projector resolution and desired object size.


A 405nm diode laser is transformed to a laser line and collimated through lenses to generate a thin homogeneous lightsheet.

The thickness of the lightsheet determines the z-resolution.


Crossing light beams (x) generate entire objects (holos). We call that xolography.

A light sheet of a specific wavelength activates a thin layer of photoinitiator. An orthogonally arranged projector beams sectional images of a 3D model into the light sheet. Only the initiator molecules absorb the light and start to polymerize.

The projection is synchronized with the moving resin volume and xoom: the desired object materializes.

Perfection down to the last Detail.

Objects printed with xolography feature smooth surfaces.
No staircases. No layering.

Xoooooom! It‘s there.
