Laser cutting and 3D printing

Laser cutting

A can use a to cut or engrave complex shapes out of card, wood, foam, plastic or circuit board.

3D printing

is an additive process that follows CAD designs to place layers on top of each other repeatedly and create a 3D object. A of plastic (Acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), Nylon) is fed into the machine and heated so that it is softened and sticks to the previous layer. It has been utilised in many industries, including in the production of prosthetics, but can be utilised in electronics also.

No moulds or formers are neededEquipment is expensive, as is maintenance
Alterations can be made to the design digitally before wasting materialsTraining is needed
It uses hardwearing, durable, waterproof and lightweight plasticsCan only use plastics
Can create complex shapesThe layering process is slow
