3-D-printable materials deform to change surface area, enabling curvature rather than rigid folding

Today's 3-D printers, in which devices rather like inkjet-printer nozzles deposit materials in layers to build up physical objects, are a great tool for designers building prototypes or small companies with limited product ...

Advanced biomaterials with silk fibroin-bioactive glass to engineer patient-specific 3-D bone grafts

The complex architecture of bone is challenging to recreate in the lab. Therefore, advances in bone tissue engineering (BTE) aim to build patient-specific grafts that assist bone repair and trigger specific cell-signaling ...

3-D printers to make human body parts? It's happening

It sounds like something from a science fiction plot: So-called three-dimensional printers are being used to fashion prosthetic arms and hands, jaw bones, spinal-cord implants - and one day perhaps even living human body ...
