| Abstract Scope |
Selective laser sintering (SLS), along with related processes like high speed sintering, are widely adopted additive manufacturing technologies in service bureaus and small-to-medium production lines, facilitating product development and fabrication of injection molded part proxies. Recent market trends show increased demand for lower-cost SLS printers, and OEMs are simultaneously focused on increasing production rates and material libraries. Radio Frequency Additive Manufacturing (RFAM) intends to address cost, speed, and materials compatibility, demonstrating the potential for volumetric fabrication of thermoplastic parts by selectively doping a powder bed with an RF absorptive material and subjecting the entire volume to RF radiation for simultaneous melting and densification. However, achieving user-ready parts with precise definition, accuracy, and repeatability requires further exploration. Key objectives include understanding and improving geometric performance, mechanical properties, recyclability, energy consumption, and cost-effectiveness. Our work concentrates on advancing RFAM through an open-system design, aiming for faster and more economical production. |
