The 3DBenchy is a 3D computer model specifically designed for testing the accuracy and capabilities of 3D printers. [1] The 3DBenchy is described by its creator, Creative Tools, as "the jolly 3D printing torture-test " and was released (initially only in STL format ) in April 2015, with a multi-part, multi-colour model released in July 2015.
The bench press or dumbbell bench-press is performed while lying face up on a bench, by pushing a weight away from the chest. This is a compound exercise that also involves the triceps and the front deltoids, also recruits the upper and lower back muscles, and traps.
STL is a file format native to the stereolithography CAD software created by 3D Systems. [ 3 ] [ 4 ] [ 5 ] Chuck Hull , the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography , [ 6 ] although it is also referred to as standard triangle language or standard ...
The main anatomical planes of the human body, including median (red), parasagittal (yellow), frontal or coronal plane (blue) and transverse or axial plane (green).. A fly or flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle.
The latissimus dorsi muscle is best targeted with the elbow close to the torso, bringing it to the hip. It is assisted by the lower trapezius fibers in adducting the scapulae. The latissimus dorsi originate in fascia of the lower back, so the mass is pulled to a place closer to the pelvis. This reduces the amount of work the lower back has to do.
This movement has also been described as negative training. This "negative" movement is necessary to reverse the muscle from its initial trajectory. [1]When the load exceeds the force that can be developed by the muscle at a constant length, as in an eccentric muscle action, the exercise is referred to as involving negative work, because the muscle is absorbing energy.
It was principally designed to store three-dimensional data from 3D scanners. The data storage format supports a relatively simple description of a single object as a list of nominally flat polygons. A variety of properties can be stored, including color and transparency, surface normals, texture coordinates and data confidence values.
