What Is 3D Printing?
3D printing is a way of printing a product out from a three-dimensional digital model. It’s done by placing layers of material on top of each other thus making a 3D printed product. That way your printer is able to 3D printing any model created in 3D, and it’ll be printed exactly as it’s made in CAD.
History And Development Of 3D Printing
The earliest records came from Japan during 1981 where Japanese inventor Hideo Kodama created a product by using ultraviolet lights to harden polymers and make them into solid objects, and that was the start of stereolithography (SLA). Later during the 1980s, Charles Hull invented stereolithography which was the process similar to 3D printing today and uses the technology to create objects of smaller proportions. Creating a smaller version of an object was necessary so they could be tested before creating real-sized ones. That way they were able to save both time and money. Creation of the object was done by simply placing a layer over another layer and rinsing them with solvents. After it’s done, the object was hardened with ultraviolet light. The entire process is done with the help from AutoCAD programme (Auto Computer-Aided Design) to create 3D models. The more advanced form of 3D printing Dubai is Selective Laser Sintering (SLS) that uses additive manufacturing with powder polymer (nylon) to create objects. SLS uses a laser to fuse powder molecules together creating more precise and complex shapes than SLA could ever do. Another form of 3D printing that came out later was Fused Deposition Modeling (FDM) invented by Scott Crump, and it’s the most common form of 3D printing today. Also known as the “3D desktop printers,” since it’s the most used form of technology. The process of creating an objects starts with the heating the cable of thermoplastic into a liquid state, and further layering the liquid into creating a 3D shape.
