1 Introduction. The idea of ​​a DIY maker is really coming into the limelight thanks to the "3D printer". It is one of the most exciting innovations in emerging technology in recent times. 3D printing technology has made its way into the technological world, this technology may be closer than you think. 3D printing is making it easier and faster to produce complex objects with multiple moving parts and complex designs. It extended the realistic possibility that anyone, anywhere in the world, could produce any item they needed 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 rolling out successive layers of material. Also known as rapid prototyping, it is a prototyping process in which a real object is created from a 3D drawing. Designers create models using computer-aided design (CAD) software, then machines follow that software model to determine how to build the object. The digital 3D model is saved in STL format and then sent to the 3D printer, then it prints the design layer by layer and forms a real object. 3D printing is also known as desktop manufacturing. Now, you can create a complete model in a single process using 3D printing.1.2 Source of 3D printing. In the year 1986, 3D printing technology made its way into the technological world, but it did not gain prominence until 1990. The 3D printer was not very popular in some industries such as engineering, architecture, and manufacturing. Chuck Hull is the co-founder and inventor of the 3-D system for printing 3D physical objects from digital data in 1984. In 1986 he called the technique stereolithography and obtained the patent. Stereo lithography (3D printing), the first trade......half of the paper......t binds the underlying layer. The platform lowers 1/6 inch after a layer is completed, to actually make room for the new layer of plastic. The time it takes to print really depends on the actual size of the object you are creating. Usually objects as small and tiny as 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 compared to stereolithography or selective laser sintering. The supporting elements and materials are removed after an object comes to life by immersing it in a solution of water and detergent or in the case of thermoplastic supports and tearing away the supporting materials part by hand. Newly created objects can also be plated, sanded, milled or painted to improve their function and appearance.
