A 3D Printer is a square or rectangular machine which is able to create 3D objects out a variety of materials. An object is first modeled in a 3D program, and then sent to the 3D printer. The printer then splices the 3D object into layers, and is able to print from the bottom of the base to the top of the object over many hours. Depending on the machine, 3D printers typically utilize ABS, PLA, or PVA Filaments to print objects with. 3D Printers can often be found in design offices, schools, and even for the hobbyist in the occasional creative household.
Currently, there are 9 basic types of 3D printers available. The different types of 3D printers include Fused Deposit Modeling (FDM), Stereolithography (SLA), Digital Light Processing (DLP), and Selective Laser Sintering (SLS). The other types of 3D printers are Selective Laser Melting (SLM), Electron Beam Melting (EMB), Laminated Object Manufacturing (LOM), Binder Jetting (BJ), and Material Jetting/Wax Casting.
The 3D printer was invented by Charles Hull in the mid-1980s. Charles Hull, later went on to fund the company 3D Systems, a company that sells 3D printers with a variety of technologies. These 3D printing technologies range from entry-level kits to advanced commercial 3D printing systems.
You can make money with a 3D printer by making pre-made 3D prints, offering specialized training on 3D printing, starting a 3D printing business, or even selling an online 3D printing course. You could also start a YouTube channel and create content on 3D printing or offer 3D scanning services.
