3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
The vision is to 3D print powdered food layers that have a shelf life of 30 years instead of using traditional freeze dried food that have a shelf life of 5 years. [36] In addition to dietary requirements, 3D printing food in space could provide a morale boost, as the astronauts would be able to design custom meals that are aesthetically pleasing.
Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
The term "Three-Dimensional Printing" was trademarked by the research group at MIT, along with the abbreviation 3DP. [5] [6] As a result, the term "3D printing" originally referred uniquely to the binder jet printing process prior to gaining wider acceptance as a term referring to all additive manufacturing processes.
3D printing is used to manufacture moulds for making jewelry, and even the jewelry itself. [102] 3D printing is becoming popular in the customisable gifts industry, with products such as personalized models of art and dolls, [103] in many shapes: in metal or plastic, or as consumable art, such as 3D printed chocolate.

Party guests playing a game of Mafia. Party games are games that are played at social gatherings to facilitate interaction and provide entertainment and recreation. Categories include (explicit) icebreaker, parlour (indoor), picnic (outdoor), and large group games. [1] [2] Other types include pairing off (partnered) games, and parlour races. [2]
3D printing marketplaces are a combination of file sharing websites, with or without a built in e-commerce capability. Designers upload suitable files for 3D printing whilst other users buy or freely download the uploaded files for printing.
A slicer is a toolpath generation software used in 3D printing. It facilitates the conversion of a 3D object model to specific instructions for the printer. The slicer converts a model in STL (stereolithography) format into printer commands in G-code format. This is particularly usable in fused filament fabrication and other related 3D printing ...
