A manufacturing process that builds objects layer by layer by adding material, as opposed to traditional methods that remove material.

AM offers numerous advantages, including reduced material waste, increased design freedom, faster prototyping, and on-demand production.

A 3D equivalent of a pixel, representing a single point of material in a 3D model.

A process of quickly creating physical prototypes using AM technology for testing and evaluation.

A virtual representation of a physical object, used for design, analysis, and simulation.

A legal document protecting an invention for a certain time period, giving the inventor exclusive rights to use, sell, and make it.

A manufacturing method that allows the creation of complex shapes without the need for molds.

3D Printing refers to a specific technology, while AM encompasses a broader range of technologies that involve adding material layer by layer.

A standard file format for 3D models used in AM machines.

Computer-Aided Design software that enables engineers and designers to create virtual 3D models.

An AM process that uses a heat source to fuse powder particles together, layer by layer.

A PBF process that uses a laser to selectively melt and fuse powder particles, forming a solid layer.

A PBF process that uses a laser to completely melt powder particles, creating a dense and solid layer.

A PBF process that uses an electron beam to melt and fuse powder particles, creating a solid layer.

An AM process that uses a liquid photopolymer resin that solidifies when exposed to light.

An AM process that uses a laser to selectively solidify liquid photopolymer resin, layer by layer.

An AM process that uses a projector to project light patterns onto liquid photopolymer resin, solidifying layers simultaneously.

An AM process that uses oxygen and light to continuously solidify photopolymer resin, creating parts faster.

A material that changes its properties, usually hardening, when exposed to light.

A chemical in photopolymer resins that initiates the polymerization process when exposed to light.

Temporary structures created during AM to support overhangs and complex shapes.

Operations performed after AM to clean, finish, or improve the properties of the printed part.

The molten area of powder particles created by a laser or electron beam during PBF processes.

A phenomenon where molten material in a melt pool shrinks and forms spheres instead of a continuous track, leading to defects in the final part.

An effect caused by overheating in the melt pool, leading to expulsion of liquid droplets and unmelted particles.

A material that has a gradual change in properties from one side to the other, enhancing its performance.

A visual technique for brainstorming and organizing ideas by connecting related concepts.

Life Cycle Assessment, which analyzes the environmental impact of a product throughout its entire lifecycle.

A technology that disrupts existing markets and industries, creating new opportunities and challenges.

A device that emits a high-intensity beam of concentrated light.

A device that controls the direction of a laser beam by deflecting it using mirrors.

Computer Numerical Control machine that uses computer programs to control the movement of cutting tools for manufacturing.

A device that converts electrical or hydraulic signals into mechanical motion.

A device that detects and measures physical quantities, such as temperature, pressure, or light.

The choice of material is crucial for AM, as different materials have unique properties that affect the final part's performance.

Ceramics are used in AM because of their unique properties, such as high heat resistance, durability, and wear resistance.

Sintering involves partially melting powder particles to bind them together, while full melting completely melts the powder for a solid part.

Patents protect inventions, allowing inventors to control the use of their technology, driving innovation and protecting intellectual property.
