Reduced Lead Time and Cost While Ensuring High Accuracy and Quality
ExOne® 3D printing technology reproduced damaged impeller with high efficiency.
Due to cracks and corrosion resulting from cavitation, the customer needed to replace a vertical pump impeller. The pump was over twenty years old and no longer in production. Without available spares, the customer urgently needed an identical replacement part while working with a limited budget.
Additive manufacturing using ExOne® binder jetting technology to print a complete sand mold package in less than one week. This precise and efficient process ensured highly accurate blade orientation, minimizing post-casting machining time.
The ExOne Competitive Advantage
Significantly faster production time, reduction in costs and the ability to ensure quality and accuracy when providing castings.
ExOne digital part materialization uses three-dimensional printing to create complex molds and cores directly from 3D CAD data for a variety of industries with accuracies of ± 0.011 in. (± 0.3 mm). The ExOne® process achieves geometric complexity and scale unmatched using conventional casting techniques without the need for a physical pattern. The process produces accurate, uniform cores and molds rapidly, significantly reducing lead times
