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.
In 3D printing, the bulk of each printed layer, regardless of complexity, is deposited by the same, rapid spreading process. [9] As with other powder-bed technologies, support structures are generally not required because loose powder supports overhanging features and stacked or suspended objects.
3D printing, and open source 3D printers in particular, are the latest technology making inroads into the classroom. [158] [159] [160] 3D printing allows students to create prototypes of items without the use of expensive tooling required in subtractive methods. Students design and produce actual models they can hold.
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 rising trend of food 3D printing [12] supports the customisation of shape, colour, flavour, texture and nutrition of different meals. Multi-material 3D printing enables using multiple ingredients like peanut butter, jelly or dough in the printing process, which is essential for the creation of most foods.
RepRap (a contraction of replicating rapid prototyper) is a project to develop low-cost 3D printers that can print most of their own components. As open designs , all of the designs produced by the project are released under a free software license , the GNU General Public License .
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Design for additive manufacturing (DfAM or DFAM) is design for manufacturability as applied to additive manufacturing (AM). It is a general type of design methods or tools whereby functional performance and/or other key product life-cycle considerations such as manufacturability, reliability, and cost can be optimized subjected to the capabilities of additive manufacturing technologies.
