US 2026/0306236 A1 · METHODS AND SYSTEMS FOR REMOTE DISTANCE PRINTING

Abstract

The present invention introduces a new concept in additive manufacturing (AM) by printing remotely without direct access to printing locations. Common energy sources in AM, heat and light, have small penetration into an optically opaque medium. However, the present invention introduces a deep penetration access to the printing medium using acoustic waves. Acoustic wave patterns create chemically active regions in which the printing material is solidified. The printing material may be a heat curing polymer or polymer composite. This concept introduces a new paradigm in non-invasive/minimally invasive bio-printing inside body, without open surgery, which is proved experimentally in this patent. In addition, a new concept of printing underneath solid and opaque shells with industrial application especially in aerospace is introduced, generated individually with dimensions smaller than those currently achieved;

Claims25

Dependent claims

A method for forming a three dimensional (3D) object comprising:

providing one or more acoustic sources configurable to generate a pressure field comprising at least one of a focused pressure field and an unfocused pressure fields within a print material;
and
moving the pressure field by moving at least one of a subset of the one or more acoustic sources or adjusting phases of the pressure fields generated by the one or more acoustic sources;
wherein
the pressure field generated by the one or more acoustic sources triggers the generation of a highly chemical active region within the printing material thereby solidifying a portion of the printing material such that the moving pressure field forms the 3D object.
