3D printing – the technology of the future that is already here

What about 3D printing?

How does 3D printing work?

  • Creating a 3D model – The digital plan is created in CAD software or by 3D scanning.
  • Slicing – The design is divided into layers by special software so that the printer knows exactly where and in what order to build the object.
  • Printing – The printer dispenses material (e.g. plastic, metal, resin) from a nozzle, building up the final object layer by layer.
  • Post-processing – In some cases, sanding, painting or heat treatment is necessary for the perfect final result.

What technologies exist?

There are several types of 3D printing, the most popular of which are:

  • FDM (Fused Deposition Modeling): A cheap, accessible technology that uses plastic filament. It is the most common in home printers.
  • SLA (Stereolithography): Uses a photosensitive resin that is hardened by laser or UV light. Very precise, but more expensive.
  • SLS (Selective Laser Sintering): Powder-based printing where the material is fused together with a laser. Professional industrial solution.
  • Metal printing (DMLS, EBM): Metal powder is fused together with a laser or electron beam, so even aircraft parts can be made.

Where is 3D printing used?

  • Industry and prototyping
  • Medicine
  • Architecture and design
  • Education and hobby
  • Food industry
