Samsung Applies for U.S. Patent for Holographic 3D Printer
Samsung has filed for a patent with the U.S. Patent Office for a holographic 3D printer.
Samsung has yet to enter the 3D-printer market, but earlier this year in February, the company indicated it was interested in 3D printing and also submitted a patent to the U.S. Patent Office for a 3D printer that use multi-color inks (see story here).
The Samsung holographic 3D printer includes a light source, a beam splitting and expanding unit, an illumination unit, a spatial light modulator (SLM), an objective lens unit, and a reference beam forming unit.
The patent states: “A laser beam is emitted from the light source, and the emitted beam is split into a reference beam and a signal beam via the beam splitting and expanding unit, expanding the signal beam via the beam splitting and expanding unit, extracting the expanded signal beam via the illumination unit, collimating the extracted signal beam via the illumination unit, modulating the collimated signal beam via the SLM, emitting the modulated signal beam from the objective lens unit to a holographic recording medium, and emitting the reference beam from the reference beam forming unit to the holographic recording medium.”
