3D printing i.e. additive manufacturing involves a layer by layer process to create physical objects out of digital 3D blueprints. It was mainly used for rapid prototyping in the late 1980’s. However, it has now become a next-generation technology which can produce localised, on-demand final products or even spare parts. 3D printing is possible with a range of thermoplastics, metal alloys, ceramics & various foodstuffs. It has seen an application in diverse areas like aerospace, retail, supply chain optimisation, & the medical industry. The 3D printed Hip & Knee Implants Market could dramatically improve both the effectiveness of surgery along with reducing the time taken to recover. It was pioneered by Dr Susannah Clarke and has already been used in hundreds of hip & knee surgeries across the world. It uses CAT scans to create a 3D blueprint of the damaged hip or knee joint to be replaced. Surgeons can then use this to practice the operation on a computer, deciding beforehand where to make incisions or how to realign the bone. The 3D printed hip & knee implant market will help to make replacement surgery much safer & quicker in the long run.
