MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202541032025 A) filed by Manipal Academy Of Higher Education on September 30, 2025, for A System And Method For Depositing A Soft Material On A Printing Surface.
Inventors include Spoorthi Singh; Ramya S Moorthy; and Shreehan B.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A modular pneumatic extrusion 3D printing apparatus (200) deposits a soft material on a printing surface. A cone-shaped extruder (100) comprises an inflatable elastomeric membrane pad (101) applying a uniform radial pressure on a material-filled cone in a cone holder (103), extruding the soft material through a nozzle for clog-free deposition. A piston pump (207), comprising a cylinder (303), piston (305), and motor (309), generates a regulated pneumatic pressure delivered to the inflatable elastomeric membrane pad (101). An X-axis frame (201), a Y-axis frame (203), a Y-axis slider (205), and a Z-axis assembly (209), each driven by a positioning motor, position, and a motor with roll arm (105) and a yaw arm (107) orient, the cone-shaped extruder (100) relative to the printing surface; and a camera module (211) monitors the soft material during deposition.
