3D Printing: An Overview

3D printing, or additive manufacturing, has revolutionized the way we design and produce objects. This technology, which allows for the creation of three-dimensional objects from a digital model, has found applications in numerous sectors, from industrial production to design, from medicine to construction.

The Main Technologies of 3D Printing

  • FDM (Fused Deposition Modeling): One of the most widespread and accessible technologies. It uses a thermoplastic filament that is extruded and deposited layer by layer to form the object. It is ideal for rapid prototyping and small series production.
  • SLS (Selective Laser Sintering): Uses a powder of thermoplastic or metallic material that is sintered layer by layer by a laser. Ideal for producing strong and complex parts, such as mechanical components and prostheses.
  • MJF (Multi Jet Fusion): An innovative 3D printing technology developed by HP. It stands out from other technologies for its unique printing process that offers significant advantages in terms of speed, quality, and versatility.
  • SLA (Stereolithography): Based on the curing of a liquid photopolymer using a UV laser beam. It offers very high resolution and smooth surfaces, making it perfect for producing detailed models and functional prototypes.
  • Binder Jetting: A 3D printing technology that uses a series of resin jets to build an object layer by layer. This process allows for the creation of objects with a wide variety of materials and colors.
  • DLP (Digital Light Processing): Similar to SLA, but uses a UV light source projected onto an entire surface to solidify the resin. It offers a higher printing speed compared to SLA.
  • Carbon Digital Light Synthesis (Carbon DLS): Carbon DLS is an innovative 3D printing technology that uses ultraviolet light to solidify a liquid resin. This process allows for the creation of three-dimensional objects with very high precision and quality.
  • DMLM (Direct Metal Laser Melting): A metallic 3D printing technology that uses an electron beam to melt metal powders. While DMLS only melts the surface of the material, DMLM completely melts the material, creating a dense and uniform metallic solid.
  • SLM (Selective Laser Melting): A metallic 3D printing technology that uses a laser beam to melt and form a metallic material. This process allows for the creation of objects with a wide variety of materials and colors.
  • Large Format FDM: refers to FDM 3D printers designed to produce objects significantly larger than standard FDM printers.
  • MJP (Multi Jet Printing): A 3D printing technology that uses a series of resin jets to build an object layer by layer. This process allows for the creation of objects with a wide variety of materials and colors.
