| Abstract Scope |
Bulky ceramic components including dendritic networks were fabricated by stereolithographic additive manufacturing. 2D cross sectional patterns were created through photo polymerization by ultra violet laser drawing on a spread resin paste including ceramic nanoparticles, and 3D composite models were sterically printed by layer lamination through chemical bonding. Photo sensitive acrylic resins with hydroxyapatite of 3 μm in particle diameter at 50 vol. % were spread on a glass substrate with 10 μm in layer thickness. An ultraviolet laser beam of 355 nm in wavelength was adjusted from 10 to 100 μm in variable diameter and scanned. Irradiation power was changed automatically from 10 to 200 mW to obtain enough solidification depth for layer by layer joining. Cross sectional patterns were laminated to create solid objects. |
