3D printing or Additive manufacturing (AM) is nothing but creating functional or mechanical physical objects using different materials by laying down thinly sliced successive horizontal layers of material.
3D printing in Construction
A house can be constructed in twenty hours with an FDM 3D printer mounted on a robotic arm that uses concrete to make a 3D model. With this Crafting technology which demonstrated all the qualities needed to use additive manufacturing on construction sites resulted in a reduction in costs and waste, faster construction speed, reduction of accidents and also helped in the construction of complex architectural shapes.
Art and design
Additive manufacturing technologies have given strength to the imagination with their ability to bring forth personalized and creative works. There is widespread usage of 3D printed models, tools, home decor and toys available in the market. Manufacturers also allow customers a personalized plan for any given model to be manufactured. Apart from art, 3D printing is being used to make various essential household things like personalized toothbrush, shoes, furniture or even a Christmas tree with recycled plastic.
3D printing has eased up manufacturing of various essential functional parts for human implants or equipment manufacturing. Along with Hearing aids and a few medical types of equipment, functional human organs are being made. Example Human heart, the heart is one of the easiest to mimic because its primary function is to act as a pump and doesn’t employ any complex biochemical reactions. Customized prosthetic limbs are being made as every disabled person has different requirements.
Metal printing has revolutionized manufacturing industries and supply chain industries. 3D printing has enabled to create personalized functional equipment domestically, without the need to import from a different place or a country. This saves international shipment and tariff charges, and it is also economical, functional, save time and money.
Aerospace and automotive industry
Metal 3D printing is currently used to create tool components and finished parts in the aerospace and automotive sectors. This technology can produce aircraft components and rocket motors, reducing weight and lowering costs. Scientists predict that astronauts may create their equipment in space in case of making a base on the moon.
