Abstract
High speed sintering (HSS) has emerged in recent years as a new powder-based additive manufacturing process similar to selective laser sintering (SLS). Instead of using a high-power laser to selectively sinter desired cross-sections, HSS uses carbon black ink to selectively absorb infrared radiation energy from a low-cost infrared source. To study the HSS process, a prototype system was built using low-cost, open source designs. A combination of manual and automated control was implemented for this prototype system. The primary goal of this research is to study HSS parameters for the prototype system and their effects on printed PA2200 nylon specimens. The volume of ink deposited on a powder surface area is investigated using a high-speed imaging system. By measuring the ink drop volume and drop ejection rate, the ink volume is calculated. The surface roughness of sintered PA2200 specimens is investigated using optical microscopy. Finally, the HSS prototype system is evaluated and used as a guiding influence for future system design recommendations.
