3D printing means creating physical-three dimensional objects through additive processes. Also known as additive manufacturing, 3D printing involves adding a material layer one by one to make the object. This process is unique because it makes it possible to solidify materials like powder grains or liquid molecules and create a 3D object – all by using computer software. Unlike traditional manufacturing, 3D printing requires less material to make complex shapes and even allows you to manufacture objects from your own home. The best part is that you can do a lot with a 3D printer, whether creating a toy for your child or a new door handle.
