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, 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.
3D printers use a variety of methods and technology to assemble physical versions of digital objects. Typically desktop 3D printers can make small plastic 3D objects. They use a roll of thin plastic filament, melting the plastic and then depositing it precisely to cool and harden.
The conventional construction method had higher impacts when compared to the 3D printing method with global warming potential of 1154.20 and 608.55 kg CO2 eq, non-carcinogenic toxicity 675.10 and 11.9 kg 1,4-DCB, and water consumption 233.35 and 183.95 m3, respectively.
[1] [2] Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology. [3] The first methods for rapid prototyping became available in mid 1987 and were used to produce models and prototype parts.
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.
