3D printing is an additive manufacturing process which creates a three-dimensional object from a digital model. At the uOttawa Makerspace, we use FDM (fused deposition modeling) which works by slicing the model into layers and then printing one layer on top of the other. The type of printer, and the options that are fitted to the printer, determine the capabilities in terms of accuracy, speed, and complexity a printer is capable of. The printer extruder and nozzle combination will dictate what materials the printer is capable of using. Multiple extrusion heads enable for different materials to be used during the same print and are common on more commercially-targeted products but can also be fitted to high-end personal-use models. This can enable a printer to use weaker (or even dissolvable) support material for easy removal, or the ability to add colour schemes to a print for aesthetic purposes. Heated build plates are fairly common, and are used to improve the quality of prints by reducing the heat stress placed on a component during printing and cooling. In addition, many printers are open source projects, enabling users to edit the printer’s software, and even use it to build their own printer. The material most commonly used in the Makerspace is a type of plastic known as PLA (Polylactic acid). This plastic is used for 3D printing because of its relatively low melting point and very low shrinkage rate. While the Makerspace owns a variety of FDM printer models, this beginner page will focus on the Ultimaker 2+ which is the main model of printer used. Most of the material in this wiki page is also covered in the CEED's interactive trainings. If you wish to follow the virtual 3D printing training, it is available [https://makerepo.com/jboud030/1220.imprimante-3d-virtuelle-virtual-3d-printing at this link].
