Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed.

This form of technology, known as “cold spray,” results in mechanically robust, porous structures that are 40% stronger than similar materials made with conventional manufacturing processes. The structures’ small size and porosity make them particularly well-suited for building biomedical components, like replacement joints.

Selective laser sintering is one of the most widely used processes in additive manufacturing, but it is limited to printing with a single material at a time. Robotics engineers have now developed a new approach to overcome this limitation: By inverting the laser so that it points upwards, they’ve invented a way to enable SLS to use – at the same time – multiple materials.

Additive manufacturing – or 3D printing – uses digital manufacturing processes to fabricate components that are light, strong, and require no special tooling to produce...

Tissue implants customized to a patient could soon be printed using a new type of 3D-printer under development by Nanyang Technological University, Singapore (NTU Singapore) and a Singapore-based 3D printing start-up focused on healthcare. This new printer can print the supporting structure layer by layer and insert living cells to form a live tissue that could aid in regeneration of particular tissues or organs. The industry research tie-up is one of the many partnerships made possible by the National Additive Manufacturing Innovation Cluster, also known as NAMIC.

Since the formation of NAMIC by the National Research Foundation (NRF) Singapore and SPRING Singap...
