  • 3D printing is the process of making a three-dimensional solid object from a digital model.

  • 3D printing, or additive manufacture, is where layer

  • upon layer of material is built up to make an object.

  • The beauty of this technique is that almost any

  • shape can be created in this way.

  • So, how do you actually print something in 3D?

  • There’s a few stages that a project will need to go through.

  • First, a design for the object needs to be completed.

  • This computer generated model is sliced into cross-sections for the printer to use as a

  • guideline.

  • The next step is printing the object.

  • The 3D printer reads the blueprint and lays down

  • successive layers of material to build the model.

  • A diverse range of materials can be used such as

  • plastics, metal, paper and ceramic.

  • As each layer is printed, it sticks to the previous

  • one to create a cohesive final shape.

  • 3D printers are capable of printing complex layers that can

  • form moving parts, like hinges and wheels, as part of the same object.

  • You could build a bicycle - with handlebars, frame,

  • wheels - readily assembled, without the need for any tools.

  • You just have to leave gaps in the right spots.

  • 3D printing is used across a variety of industries such as

  • high-end manufacture, where it’s used for rapid prototyping and research.

  • This allows designers and concept developers the flexibility

  • to produce parts and models on demand.

  • They are then able to modify these as required.

  • And finally, 3D printing is pushing healthcare into new areas.

  • It’s being used to make medical parts such as custom hearing

  • aids and braces and even to reproduce body parts like customised

  • hip implants or prosthetic hands in exact proportions to fit the patient.
