MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617063782 A) filed by D Systems, Inc. on May 20, 2026, for Phase Change Ink Printing System Utilizing A Composite Waveform.
Inventor includes Korol, Steven Van Cleve.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A 3D printing system (2) includes a build plate (6) supporting a 3D article (4), a drop on demand piezo (DODP) printhead (10), a horizontal movement mechanism (14), a supply (12) of phase change ink, and a controller. The controller (20) is configured to: operate the supply (12) and the DODP printhead (10) to maintain a liquid state of the phase change ink, position an upper surface of the 3D article at a build plane, scan the printhead over the upper surface, and operate the DODP printhead to deliver ink drops (55, 57) to pixel locations upon the upper surface. The operation of the DODP printhead includes, for individual ones of the ink drops: apply a secondary waveform (54) to a piezo actuator followed by a primary waveform (56) to the piezo actuator to generate two drops (55, 57) of liquified phase change ink that merge in flight before reaching and solidifying on the upper surface.
