Core XY
CoreXY is a technique used to move the printhead of a 3D printer or the toolhead in CNC machines in the horizontal plane. The advantage of this technique is that the two motors used to perform the movement in the horizontal plane are stationary and do not have to move themselves, which can result in less moving mass. Instead, drive belts are used which are connected in an intricate way to provide movement in a Cartesian coordinate system. Compared to conventional Cartesian 3D printers for fused filament, it can provide increased printing speed due to less moving mass. Movement For movement along the ''x''-axis, both motors must rotate in the same direction. For movement along the ''y''-axis, the motors must rotate in opposite directions. If only one motor rotates, the movement will be diagonal. The movement can be mathematically described as follows. If ''A'' is the movement of the first motor and ''B'' the movement of the second motor, the movement in the ''x'' and ''y'' dire ...

3D Printer
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology; in this context, the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise infeasibl ...

Mass
Mass is an Intrinsic and extrinsic properties, intrinsic property of a physical body, body. It was traditionally believed to be related to the physical quantity, quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particle, elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple Mass in special relativity, definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure (mathematics), measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the Force, strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is Mass versus weight, not the same as weight, even though mass is often determined by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belt (mechanical)
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text of the ''Dictionary of Local Expressions'' by the Han ...

Cartesian Coordinate System
In geometry, a Cartesian coordinate system (, ) in a plane (geometry), plane is a coordinate system that specifies each point (geometry), point uniquely by a pair of real numbers called ''coordinates'', which are the positive and negative numbers, signed distances to the point from two fixed perpendicular oriented lines, called ''coordinate lines'', ''coordinate axes'' or just ''axes'' (plural of ''axis'') of the system. The point where the axes meet is called the ''Origin (mathematics), origin'' and has as coordinates. The axes direction (geometry), directions represent an orthogonal basis. The combination of origin and basis forms a coordinate frame called the Cartesian frame. Similarly, the position of any point in three-dimensional space can be specified by three ''Cartesian coordinates'', which are the signed distances from the point to three mutually perpendicular planes. More generally, Cartesian coordinates specify the point in an -dimensional Euclidean space for any di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fused Filament Fabrication
Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or ''filament freeform fabrication'', is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer. The speed of the extruder head may also be controlled to stop and start deposition and form an interrupted plane without stringing or dribbling between sections. "Fused filament fabrication" was coined by the members of the RepRap project to give an acronym (FFF) that would be legally unconstrained in use. Fused filament printing has in the 2010s-2020s been the most popular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Printing Speed
In 3D printing, the printing speed is a measure for how much material is printed per unit of time (\text / \text). It's an important parameter for the time it takes to print, and can affect the quality of the print. Units used varies depends on the type of additive manufacturing technique. The unit of manufactured material is typically measured in units of either mass (Kilogram, kg), length (Millimeter, mm) or volume (Cubic centimetre, cm3), and the unit of time is usually measured in seconds (or sometimes hours). For example, fused filament fabrication typically uses mm/s or mm3/s, while stereolithography typically uses mm/h or layers per hour. Examples The following table compares typical speeds of some commercially relevant 3D printing technologies (updated 2020): Importance of speed for time usage 3D printing speed refers to only the build stage, a subcomponent of the entire 3D printing process. However, the entire process spans from pre-processing to post-processing sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prusa I3
The Prusa i3 is a family of fused filament fabrication 3D printers, manufactured by Czech company Prusa Research under the trademarked name Original Prusa i3. Part of the RepRap project, Prusa i3 printers were called the most used 3D printer in the world in 2016. The first Prusa i3 was designed by Josef Průša in 2012, and was released as a commercial kit product in 2015. The latest model (Prusa MK4S on sale as of August 2024) is available in both kit and factory assembled versions. The Prusa i3's comparable low cost and ease of construction and modification made it popular in education and with hobbyists and professionals, with the Prusa i3 model MK2 printer receiving Prusa i3#Recognition, several awards in 2016. The i3 series is released under an Open-source hardware, open source license, which has led to many other companies and individuals producing Prusa i3#Variants, variants and clones of the design. The i3 moniker refers to the printer being the third iteration of the des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta Robot
A delta robot is a type of parallel robot that consists of three arms connected to universal joints at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector. In contrast, a Stewart platform can change the orientation of its end effector.Bonev, I. The True Origins of Parallel Robots. Online article available at http://www.parallemic.org/Reviews/Review007.html Delta robots have popular usage in picking and packaging in factories because they can be quite fast, some executing up to 300 picks per minute. History The delta robot (a parallel arm robot) was invented in the early 1980s by a research team led by professor Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland). After a visit to a chocolate maker, a team member wanted to develop a robot to place pralines in their packages. The purpose of this new type of robot was to manipulate light and small objects at a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCARA
The SCARA is a type of industrial robot. The acronym stands for selective compliance assembly robot arm or selective compliance articulated robot arm. By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the Z direction, hence the term ''selective compliance''. This is advantageous for many types of assembly operations, for example, inserting a round pin in a round hole without binding. The second attribute of the SCARA is the jointed two-link arm layout similar to human arms, hence the often-used term, ''articulated''. This feature allows the arm to extend into confined areas and then retract or "fold up" out of the way. This is advantageous for transferring parts from one cell to another or for loading or unloading process stations that are enclosed. SCARAs are generally faster than comparable Cartesian robot systems. Their single pedestal mount requires a small footprint and provides an easy, unhindered for ...
