This invention discloses a 3D printing method and apparatus for the integrated molding of heterogeneous multi-component components, specifically relating to the fields of advanced manufacturing and intelligent microsystems technology. This invention overcomes the limitations of traditional multi-material 3D printing, which can only integrate electronic components and cannot embed drivers. It employs a dual-mode embedding method combining vacuum adsorption and pneumatic gripping, achieving integrated manufacturing of micro-drivers, electronic components, high-precision conductive lines, and structural substrates. By preparing wires through mask scraping, it solves the problems of low precision and difficulty in adapting to micro-circuits in direct writing, improving interconnect reliability and miniaturization level. The direct embedding of mature drivers avoids the polarization process and performance degradation issues required for direct printing of piezoelectric materials, ensuring stable and reliable driving performance. Through in-situ wire fabrication and a closed-loop printing process, it eliminates the risk of post-assembly errors and interconnect failures.

This invention discloses a direct printing method for flexible circuits based on a solid-liquid two-phase binary metal system. The method first selects two metals according to a binary metal phase diagram and prepares a binary metal alloy that exhibits a solid-liquid coexistence at the operating temperature. Then, it is physically dispersed with a polymer matrix, a conductivity promoter, and additives to form a composite conductive paste with shear-thinning properties. Finally, the paste is directly deposited onto a flexible substrate via screen printing, direct writing, or inkjet printing, and cured at low temperature or dried at room temperature to obtain a flexible circuit. This invention utilizes the rheological tunability and self-healing properties of solid-liquid two-phase metals, combined with the flexibility and adhesion of the polymer matrix, to solve the problems of easy leakage and patterning difficulties in traditional liquid metals, as well as the high interfacial resistance and poor flexibility of solid metal fillers. It achieves low-temperature, efficient, and low-cost printing fabrication of flexible circuits, with broad application prospects in wearable devices, flexible sensing, smart wearables, and smart packaging.

The present invention relates to a multifunctional printer system designed for printing electronic circuits directly onto fabrics, ideal for creating wearable electronics. This system integrates a laser burner, a dual-tube Hydrogen Evolution Assisted (HEA) electroplating nozzle, and a passivation nozzle into a single printer head. The laser burner creates conductive templates on the fabric by burning specific patterns, which are then metalized using the HEA electroplating nozzle to apply copper. This process is enhanced by hydrogen evolution, which improves the quality of copper deposition. Following metalization, an insulating material is applied over the copper patterns using the passivation nozzle to protect and insulate the electronic circuits. The system includes a control unit equipped with a digital microscope and image processing capabilities, enabling real-time monitoring and dynamic adjustment of printing parameters. This approach allows for efficient, precise, and scalable production of integrated electronic textiles.
