Rat Rig
Rat Rig is a Portuguese manufacturer of modular 3D printers and CNC machines based on T-slot structural framing, structural aluminum profiles. They are known for their V-Core series of 3D printers, which are CoreXY printers with open source and open hardware. Along with Voron Design, Voron and VzBot, Rat Rig has been one of the pioneers in the commercialization of 3D printers with CoreXY kinematics, a printer type that has since been adopted by major commercial players such as Prusa Research, Prusa, Creality, Bambu Lab, and others. Rat Rig has distinguished itself in that their printers can be constructed relatively large, with build volumes of up to 500×500×500 mm, compared to, for example, 250×210×210 mm for the reference printer Prusa i3 or 350×350×350 mm for the (also relatively large) Voron 2.4. They have stated that they are committed to open design principles, using mainly Standardization, standard or Modularity, modular components that give users the fr ...

3D Printing
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 infeasi ...

Hotend
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 trave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Maker Movement
The maker culture is a contemporary subculture representing a technology-based extension of DIY culture that intersects with hardware-oriented parts of hacker culture and revels in the creation of new devices as well as tinkering with existing ones. The maker culture in general supports open-source hardware. Typical interests enjoyed by the maker culture include engineering-oriented pursuits such as electronics, robotics, 3-D printing, and the use of computer numeric control tools, as well as more traditional activities such as metalworking, woodworking, and, mainly, its predecessor, traditional arts and crafts. The subculture stresses a cut-and-paste approach to standardized hobbyist technologies, and encourages cookbook re-use of designs published on websites and maker-oriented publications. There is a strong focus on using and learning practical skills and applying them to reference designs. There is also growing work on equity and the maker culture. Philosophical emphasis ...

Acrylonitrile Butadiene Styrene
Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)''x''·(C4H6)''y''·(C3H3N)''z'' ) is a common thermoplastic polymer. Its glass transition temperature is approximately . ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene crisscrossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The polybutad ...

Small And Medium Enterprises
Small and medium-sized enterprises (SMEs) or small and medium-sized businesses (SMBs) are businesses whose personnel and revenue numbers fall below certain limits. The abbreviation "SME" is used by many national agencies and international organizations such as the World Bank, the OECD, European Union, the United Nations, and the World Trade Organization (WTO). In any given national economy, SMEs outnumber large companies by a wide margin and also employ many more people. On a global scale, SMEs make up 90% of all companies and more than 50% of all employment. For example, in the EU, 99% of all businesses are SMEs. Australian SMEs makeup 98% of all Australian businesses, produce one-third of the total GDP (gross domestic product) and employ 4.7 million people. In Chile, in the commercial year 2014, 98.5% of the firms were classified as SMEs. In Tunisia, the self-employed workers alone account for about 28% of the total non-farm employment, and firms with fewer than 100 employees acco ...

Bill Of Materials
A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an Product (business), end product. A BOM may be used for communication between manufacturing partners or confined to a single manufacturing plant. A bill of materials is often tied to a production order whose issuance may generate reservations for components in the bill of materials that are in stock and requisitions for components that are not in stock. The first Hierarchical database model, hierarchical databases were developed for automating bills of materials for manufacturing organizations in the early 1960s. At present, this BOM is used as a database to identify the many parts and their codes in automobile manufacturing companies. A BOM can also be visually represented by a Product structure modeling, product structure tree, although they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical Drawing
Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128. The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanings are multiply determined. Technical drawings are understood to have one intended meaning. A draftsman is ...
