Abstract Scope |
Current engineering technologies demand the ability of obtaining 3D structures in a green and a cost-effective way. In this work, we developed original inks and implemented printing technique to print 3D metallic structures at room temperature using various metallic powders (including magnetic and magnetocaloric powders), and cellulose as matrix with water as dissolvent. The ink containing more than 85 wt.% of powder was elaborated by achieving an optimal viscosity whereby high maximum number of layers (250 layers reached) with highest printing resolution (0.5mm wall thickness) was obtained. The elaborated technological route of the treatment of printed structures included: (i) special heat treatments to dry printed structures so the polymer was removed by calcination followed by a sintering to get entirely metallic structure, and (ii) electrodeposition of nickel to protect printed structure from any corrosion. We also demonstrated that any incorrectly printed workpiece can be recycled re-dissolving it in the water so material loss is reduced significantly making the printing more cost-efficient and environmentally friendly. |
