Due to the layer structure and the production without tools, 3D-printed parts have a higher surface roughness. The higher surface roughness can lead to an initially higher coefficient of friction, as shown below (iglidur I3). After a short period of time, the mating surfaces have “worn out” so that the roughness and coefficient of friction […]
A 3D printer is a machine with which a three-dimensional object can be made, for instance, by melting plastic or metal. No tools are needed. An appropriate design file (3D model or CAD file) is required for the manufacture of an object. The item is manufactured in the 3D printer based on this file. The […]
Basically, a gear is a circular disc with regular notches (serrations) that run the full circumference. It is used to transmit (kinetic) forces to another gear or a chain. Two or more gears combined together form a gearbox. At the same radius, the wheels act on each other with the same force. If the radii […]
Simply explained, a gear is a wheel, along the outer edge of which serrations are attached. Two gears whose teeth are identical in shape and gap, can run against each other and thus transmit power from one to the other gear. The gears with the same toothing can have different sizes. With two interlocking gears, […]
There are innumerable types of 3D printer on the market, with ones for €100 as a construction kit and others costing thousands of euros. This is because the price depends on many factors such as size, quality, industrial or non-industrial use. The question, therefore, cannot be answered without these factors being taken into account. Vote […]
