Hopper for Powder Bed Fusion Additive Manufacturing
Principal Investigator : MAE, Prof Chua Chee Kai
Key Features and Innovation
- Multi-material hopper enables powder bed fusion technology to fabricate multi materials in 2 axes.
- It is able to combine materials with different materials which are conventionally difficult to be welded together, e.g. copper and stainless steel.
Potential Application
- Applicable to industries that require multi-material components e.g. heat transfer components, corrosion prevention parts, implants, electricity, gas and air-conditioning supply and transportation and storage sectors

Method of Forming Titanium-tantalum Alloys
Principal Investigator : MAE, Asst Prof Yeong Wai Yee
Key Features and Innovation
- Homogeneous titanium-tantalum alloy is obtained using selective laser melting (SLM) for the first time.
- The resulting titanium-tantalum alloy has comparable mechanical strength to Ti6Al4V, and is more suitable for biomedical applications due to its lower Young’s modulus.
- In vitro testing has also confirmed titanium-tantalum’s biocompatibility to be comparable to Ti6Al4V and pure titanium.
- Functional parts, with complex geometries, can be produced using the alloys in a single step, simultaneously with the alloying process.
