If you enjoy tinkering with machines, you have the option of building a 3D printer from scratch. You’ll still need to do calibrations and troubleshooting on a regular basis. Kits can be significantly less expensive than out-of-the-box printers. You will need to assemble the machine yourself, but all the parts will be in the kit. Look for a 3D printing kit, which has some automatic features. Some 3D printing enthusiasts are also electronics hobbyists – people who like to play with tech devices and don’t mind challenging tasks. The extruder can clog, especially when using a specialty filament, so some knowledge is needed for occasional repair. However, this type of printer requires regular maintenance and frequent cleaning. FDM printers work faster than other 3D printer types and cost less than other types. The filament is melted in an extruder, then deposited onto the print bed, layer by layer. The FDM printer uses a spool of filament, typically plastic, as the print material. FDMįDM, short for Fused Deposition Modeling, is the most common type of desktop 3D printer. Each type has a few pros and cons, as we’ll discuss next. Three major types of 3D printers are available today, though only two of those are typically affordable for home us. But as the price of 3D printing has dropped, and the technology has evolved, manufacturers now sell smaller printers for use at home. Large manufacturing companies have used 3D modeling and printing for a few decades. (There are also plenty of places to simply download 3D models online.) The 3D printer brings the models to life, building an actual object from the computer drawing. This can be done with software or through the use of a 3D scanner. The first step in 3D printing is the creation of a model.

However, other printers can create objects from a wider variety of materials, including metals, wood, concrete, and even chocolate or confectioners sugar.

Most consumer-grade 3D printers produce objects in various forms of plastic. A 3D-printed object is exactly that - a three-dimensional, physical object. 3D printing involves a vastly different process than printing on a piece of paper with an inkjet printer.
