Additive manufacturing technology is an advanced manufacturing technique that integrates mechanics, computing, CNC, and materials. It enables the rapid production of intricate components. Originating in the 1980s, its fundamental principle simplifies three-dimensional processing into two-dimensional layers, accumulating point by point or layer by layer to ultimately obtain solid components or prototypes. Compared to traditional manufacturing methods, additive manufacturing technology offers advantages such as high design flexibility, short product development cycles, and low manufacturing costs.
Additive manufacturing techniques for ceramic components can be classified into four categories based on the form of raw materials: powder-based, filament-based, sheet-based, and liquid-based. Each technology has its characteristics and applications. For instance, Three-Dimensional Printing (3DP) employs binder jetting to solidify powder, suitable for manufacturing porous ceramic components, primarily applied in the field of biomedical tissue engineering. Laser Selective Sintering (SLS) utilizes laser scanning on powder without the need for support structures, ideal for producing intricately shaped components, albeit with higher costs.Is there anything else you would like me to translate or improve for you?
Other techniques such as laser selective melting, fused deposition modeling, layered solid manufacturing, and photo-curing molding are also introduced, with each technology having its principles, characteristics, and application scope. Among them, photo-curing molding technology includes SLA and DLP, offering high manufacturing precision and surface quality. However, it also faces challenges such as high material costs, environmental pollution, and equipment expenses.
In general, additive manufacturing technology holds vast prospects in the manufacturing of ceramic components, meeting the demands for the production of intricate structural parts.Is there anything else you would like me to translate or improve for you?
