Additive manufacturing (AM) technology has been researched and developed for more than
20 years. Rather than removing materials, AM processes make three-dimensional parts …

Advanced methods for manufacturing high quality parts should be used to ensure the
production of competitive products for the world market. Investment casting (IC) is a process …

Dimensional accuracy and geometric characteristics of the manufactured parts bear
significant importance in product assembly. In Rapid Investment Casting, these …

A ceramic core of network-structured ZrSiO 4 surrounding large particles of fused quartz was
designed. Experimental results show that the ceramic core prepared by digital light …

In view of their development at present, the advanced manufacturing processes of hollow
turbine blades are reviewed thoroughly. There are several kinds of manufacturing …

Stereolithography apparatus (SLA) is one of the most famous and versatile additive
manufacturing techniques and has been widely used in many industrial fields. However, the …

Rapid casting (RC) of freeform-surface parts can be realized via replacing wax patterns by
stereolithography (SL) patterns to overcome the disadvantage of time-and-cost consuming …

The stray grain defect is often found at the platform in the process of directional solidification
of single crystal blades because local undercooling easily occurs in this area. A variable …

Due to variable cross-sections and a thin-walled structure, gas turbine blades have stringent
dimensional, and geometrical tolerance requirements. Single-crystal hollow blades are …

The near‐net shaping of gelcast ceramic parts can be achieved using freeze‐drying
technology. It was discovered that the cracks probably occurred inside the part during freeze …
