Additive Manufacturing (3D Printing)

Detailed overview of innovation with sample startups and prominent university research


What it is

Additive manufacturing, commonly known as 3D printing, is a process of creating three-dimensional objects from a digital model by depositing material layer by layer. This technology offers significant advantages over traditional subtractive manufacturing methods, such as reduced material waste, greater design flexibility, and the ability to create complex geometries.

Impact on climate action

Additive Manufacturing (3D Printing) under Industrial Resource Efficiency drives climate action by minimizing material waste, energy consumption, and transportation emissions. By enabling on-demand production and lightweight designs, this innovation optimizes resource use, reduces carbon footprint, and fosters sustainable manufacturing practices, contributing to a more environmentally friendly industry.

Underlying
Technology

  • Fused Deposition Modeling (FDM): This technology uses a heated nozzle to extrude thermoplastic materials, layer by layer, to build an object.
  • Selective Laser Sintering (SLS): This technology uses a laser to selectively sinter powdered materials, layer by layer, to create an object.
  • Stereolithography (SLA): This technology uses a laser to selectively cure a liquid photopolymer resin, layer by layer, to build an object.
  • Selective Laser Melting (SLM): This technology uses a laser to melt and fuse metal powder, layer by layer, to create an object.
