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.
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.
3D printing filament in different colours with models created using the filament. 3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers . There are many types of filament available with different properties.
Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...
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.

On August 31, 2014, Cura was included in a review of 3D slicing software by Think3DPrint3D. [24] In the summer of 2015, Ultimaker released Cura 2.0. [25] [26] [27] On January 1, 2018, All3DP named Cura one of the best 3D slicer software tools. [8] In 2019, Cura was named one of the top free 3D printing tools by the industry blog, G2. [28]
An analysis of 3D printing construction in remote areas [120] as an alternative to conventional construction reveals significant potential. 3D printing in construction offers innovative solutions to the unique challenges of these locations. The ability to use local materials, reduce waste, and adapt to complex and customized designs are just a ...
