Abstract Scope |
Multi-material and hybrid methods have been proposed to improve the functional complexity of components fabricated using additive manufacturing. Hybrid ceramic AM integrates multiple processes such as paste extrusion, inter-layer drying and green machining into a single system, allowing for production of functional ceramics. Integration of these processes onto a print head reduces the build volume per axis stroke length, and working coordinate systems are used to avoid work piece collision. A tool changer mechanism has been developed that uses an electro-permanent magnet to collect and deposit the working tool. This is beneficial because the use of magnetism removes any moving parts that would be worn by ceramic particles. The electromagnet is ‘energise to release’, securing tools to the print head even in case of power failure. Incorporation of this device into AM processes creates new opportunities for multi-material and hybrid ceramic fabrication, such as LTCC embedded electronics for harsh environments. |
