In mechanical engineering, a fillet (pronounced / ˈ f ɪ l ɪ t /, like "fill it") is a rounding of an interior or exterior corner of a part. An interior or exterior corner, with an angle or type of bevel , is called a " chamfer ".
Some important 3D printer metrics include: Print technology: 3D printing processes encompasses a variety of methods which each have their own unique challenges. Length of production run and support: 3D printers often require adjustments and parts replacement. A long production run often means that spare parts are also available.
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
There are several types of 3D printer extruders. A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely used in filament 3D printers is the direct-drive extruder, which sits closer to the extruder hot end.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
A common everyday example of a boss is the housing of the rotation spindle in a washing machine drum, or on a cylinder lawn mower at the end of the cutting blade cylinder which may house a bearing set to allow the cylinder to rotate through one plane, but held firm in another plane. A boss can also be a brass eyelet on a sail.
