1 Introduction. The idea of ​​a DIY maker is really coming to the forefront thanks to the “3D printer”. This is one of the most exciting innovations in emerging technology in recent times. 3D printing technology has made its way to the technological world, this technology may be closer than you think. 3D printing makes it easier and faster to produce complex objects with multiple moving parts and a complex design. It has expanded the realistic possibility that anyone, anywhere in the world, can produce any object they need on demand.1.1 What is 3D printing? 3D printing is a form of additive manufacturing technology in which a three-dimensional object is created by depositing successive layers of materials. material. It is also known as rapid prototyping. It is a prototyping process by which a real object is created from a 3D design. Designers create models using computer-aided design (CAD) software, then machines follow that software model to determine how to build the object. The 3D digital model is saved in STL format and then sent to a 3D printer, then it prints the design layer by layer and forms a real object. 3D printer is also known as desktop manufacturing. Now a complete model can be created in a single process using 3D printing.1.2 Origin of 3D printing. In 1986, 3D printing technology made its way into the technological world, but did not gain prominence until 1990. The 3D printer was not very popular in some fields like engineering, architecture and manufacturing. Chuck Hull is the co-founder and inventor of the 3D system for printing 3D physical objects from digital data in 1984. In 1986, he named the technique stereolithography and obtained the patent. Stereolithography (3D printing), the first commercial medium of paper......does not bind the layer below. The deck is lowered 1/6th of an inch after a layer is completed, to free up space for the new layer of plastic. The time required for printing actually depends on the actual size of the item being created. Usually, small and tiny objects, like a few cubic inches or a tall, thin substance, are printed quickly, while increasingly larger and more complex objects take longer to print. FDM is a slow process when compared to stereolithography or selective laser sintering. Support elements and materials are removed after creating an object by soaking it in water and detergent solution or in the case of thermoplastic supports and tearing off the support materials by hand. Newly created objects can also be plated, sanded, milled or painted to improve their function and appearance..
