Extruder (3D Printing)
A 3D printer extruder is a 3D printing filament, filament feeding mechanism used in many fused filament fabrication (FFF) 3D printers. There are several types of 3D printer extruders. A Bowden cable, Bowden extruder is a type of extruder that pushes filament through a long and flexible Polytetrafluoroethylene, PTFE (Teflon) tube to the hot end. An alternative type of extruder which is also widely used in filament 3D printers is the Direct-drive mechanism, direct-drive extruder, which sits closer to the extruder hot end. Bowden extruder Bowden type extruders are easier to swap since they are outside the print head. They also have less chance of tangling the filament while it unwinds from the spool. Additionally, they reduce the mass of the extrusion carriage because it doesn't have to hold a stepper motor. This allows for faster changes in print head movement direction, increased print speed, increased accuracy, and decreased instances of artifacting or ghosting along the x and ...

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] |
Do It Yourself
"Do it yourself" ("DIY") is the method of building, wikt:modification, modifying, or repairing things by oneself without the direct aid of professionals or certified experts. Academic research has described DIY as behaviors where "individuals use Raw material, raw and semi-raw materials and parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g., landscaping)". DIY behavior can be triggered by various motivations previously categorized as market economy, marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity (social science), identity enhancement (Workmanship, craftsmanship, empowerment, community seeking, uniqueness). The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyman Filament Extruder
300px, right The Lyman filament extruder is a device for making 3D printing filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition. The goal in the competition was to build an open source filament extruder for less than $250 in components that can take ABS or PLA resin pellets, mix them with colorant A colourant/colour additive (British spelling) or colorant/color additive (American spelling) is a substance that is added or applied in order to change the colour of a material or surface. Colourants can be used for many purposes including printin ..., and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool.

Extruder Lemio-en
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process. Drawing is a similar process, using the tensile strength of the material to pull it through the die. It limits the amount of change that can be performed in one step, so it is limited to simpler shapes, and multiple stages are usually needed. Drawing is the main way to produce wire. Metal bars and tubes are also often drawn. Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). It can be done with hot or cold material. Commonly extruded mate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backlash (engineering)
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a Engineering tolerance, clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."p. 1-8 An example, in the context of gears and gear trains, is the amount of clearance between mated gear teeth. It can be seen when the direction of movement is reversed and the slack or lost motion is taken up before the reversal of motion is complete. It can be heard from the railway couplings when a train reverses direction. Another example is in a valve train with mechanical tappets, where a certain range of lash is necessary for the valves to work properly. Depending on the application, backlash may or may not be desirable. Some amount of backlash is unavoidable in nearly all reversing me ...

Stepper Motor
A stepper motor, also known as step motor or stepping motor,Clarence W. de Silva. Mechatronics: An Integrated Approach (2005). CRC Press. p. 675. "The terms ''stepper motor'', ''stepping motor'', and ''step motor'' are synonymous and are often used interchangeably." is a brushless DC electric motor that rotates in a series of small and discrete angular steps. Stepper motors can be set to any given step position without needing a Rotary encoder, position sensor for feedback. The step position can be rapidly increased or decreased to create continuous rotation, or the motor can be ordered to actively hold its position at one given step. Motors vary in size, speed, step resolution, and torque. Switched reluctance motors are very large stepping motors with a reduced pole count. They generally employ closed-loop commutator (electric), commutators. Mechanism Brushed DC motors rotate continuously when DC voltage is applied to their terminals. The stepper motor is known for its proper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct-drive Mechanism
A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle) without involving any intermediate couplings such as a gear train or a belt.Asada, H., & Kanade, T. (1983) Design of direct-drive mechanical arms' in ''Journal of Vibration, Acoustics, Stress, and Reliability in Design'', Volume 105, Issue 3, pp.312-316 History In the late 19th century and early 20th century, some of the earliest locomotives and cars used direct drive transmissions at higher speeds. Direct-drive mechanisms for industrial arms began to be possible in the 1980s, with the use of rare-earth magnetic materials. The first direct-drive arm was built in 1981 at Carnegie Mellon University. Today the most commonly used magnets are neodymium magnets. Design Direct-drive systems are characterized by smooth torque transmission, and nearly-zero backlash.Bruno Siciliano, Oussama Khatib (Eds., 20 ...

Hot End
A hotend is a component used in fused filament deposition 3D printers. Its purpose is to heat up and melt filament material for depositing into the intended shape. The hotend is usually made of a bulk heat-conductive material with an internal resistive heater, coupled with a thermistor or thermocouple for precise temperature control. In common desktop 3D printer designs, the heater is located near the nozzle, and a heatsink is attached upstream (on the colder side). A heatbreak component made of dissimilar metals ( bimetal) can be used to limit heat transfer to the cold filament above, increasing the controllability of the melted filament. Nozzle The nozzle is an interchangeable tip attached to the hotend with a small diameter hole through which the melted filament is extruded. In desktop fused filament deposition printers, different sized nozzle holes can be used to balance between printing speed and precision. Common large sized ones (1.0mm) extrude more material per trav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
