Optimization of Hybrid Ink Formulation and IPL Sintering Process for Ink-Jet 3D Printing

Ink-jet 3D printing technology facilitates the use of various materials of ink on each ink-jet head and simultaneous printing of multiple materials. It is suitable for manufacturing to process a complex multifunctional structure such as sensors and printed circuit boards. In this study, a complex structure of a SiO2 insulation layer and a conductive Cu layer was fabricated with photo-curable nano SiO2 ink and Intense Pulsed Light (IPL)-sinterable Cu nano ink using multi-material ink-jet 3D printing technology. A precise photo-cured SiO2 insulation layer was designed by optimizing the operating conditions and the ink rheological properties, and the resistance of the insulation layer was 2.43 × 1013 Ω·cm. On the photo-cured SiO2 insulation layer, a Cu conductive layer was printed by controlling droplet distance. The sintering of the IPL-sinterable nano Cu ink was performed using an IPL sintering process, and electrical and mechanical properties were confirmed according to the annealing temperature and applied voltage. Then, Cu conductive layer was annealed at 100 °C to remove the solvent, and IPL sintered at 700 V. The Cu conductive layer of the complex structure had an electrical property of 29 µΩ·cm and an adhesive property with SiO2 insulation layer of 5B.

3D Printing Technology

The technology of additive 3D printing is widely used in various branches of science and industry. The purpose of the research presented in the article is to evaluate and study the possibilities of 3D printing technology applied to the manufacture of microwave devices and to compare the characteristics of the devices obtained with the characteristics used in the electrodynamic model. Printing metal parts is an overly expensive process in small-scale production, both in terms of the cost of equipment and in relation to the materials used. In this work, parts for microwave devices were made of plastic with the aim of cheapening. Relatively cheap polymers used in 3D printing are dielectrics. Therefore, to limit the propagation of an electromagnetic wave in all directions it was necessary to create a conductive layer on the surface of printed models. The article: identifies the FFF print parameters that affect to the maximum extent the propagation of an electromagnetic wave; describes the process and problems encountered when printing and galvanizing parts; discusses the steps of modeling devices and measuring their parameters. The characteristics of microwave devices made by 3D printing technology were investigated. An assessment of the possibilities of manufacturing antennas and coaxial-waveguide transitions using this technology was carried out. To implement the conductive layer on the surface of the models, the method of galvanization was used. The adhesion properties of the obtained metallic coatings were investigated. The results of electromagnetic modeling are given. The parameters that affect to the maximum extent the quality of the implemented devices were determined. Laboratory measurements of the characteristics of produced devices were conducted. The simulation results of the examined devices are in good agreement with the experimental characteristics of the made models using 3D printing technology. A complete production cycle of microwave devices was carried out: design, simulation, sample production, and validation of characteristics. Prospects for the further development of the described technology include a variation of the types of plastics used as a substrate, the application of finishing decorative and functional coatings, an improvement in the adhesion properties of the applied copper layer with the substrate.

Aligned topography and biomolecular gradients exist in various native tissues and play pivotal roles in a set of biological processes. Scaffolds that recapitulate the complex structure and microenvironment show great potential in promoting tissue regeneration and repair. We begin with a discussion on the fabrication of aligned scaffolds, followed by how biomolecular gradients can be immobilized on aligned scaffolds. In particular, we emphasize how electrospinning, freeze drying, and 3D printing technology can accomplish aligned topography and biomolecular gradients flexibly and robustly. We then highlight several applications of aligned scaffolds and biomolecular gradients in regenerative medicine including nerve, tendon/ligament, and tendon/ligament-to-bone insertion regeneration. Finally, we finish with conclusions and future perspectives on the use of aligned scaffolds with biomolecular gradients in regenerative medicine.
