Selective laser melting (SLM) is a technique that also uses 3D CAD data as a source and forms 3D object by means of a high-power laser beam that fuses and melts metallic powders together. In many sources SLM is considered to be a subcategory of selective laser sintering (SLS). But this...
This type of arc welding process can have a high metal deposition rate of up to 20 kg/hour. It also has a capacity for welding metals with thicknesses up to 100mm. This type of welding is often used in heavy fabrication industries. The aviation industry, shipbuilding, railroads, and bridg...
Guided tissue regeneration is a technique that may be used along with bone grafting, where a tiny piece of mesh-like material is inserted between bone and gum tissue. This helps to segregate the gum tissue from the bone, allowing each to re-grow in its own place. Gingivectomy In some ca...
The directed energy deposition technique is widely employed in the high-tech metal industry and rapid manufacturing. This process involves a printing apparatus equipped with a nozzle attached to a multi-axis robotic arm. The nozzle deposits metal powder onto the build platform, which is then melted...
Acoustic rhinometry, a technique used widely in Europe, evaluates nasal obstruction by analyzing reflected sound waves introduced through the nares.It is generally easy to perform, is noninvasive, and does not require patient cooperation like many of the other evaluation procedures. It produces an ...
Fused deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used form of 3D printing at the consumer level, fueled by the emergence of hobbyist 3D printers. This technique is well-suited for basic proof-of-concept models, as well as quick and low...
Another technique frequently employed is the use of patterned film electrodes. By partitioning an electrode into a number of interconnected segments, the interconnects can be made to act as fuses that limit the amount of current available to a fault site during a self-healing event, allowing the...
Fused Deposition Modeling (FDM) Fused deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used type of 3D printing at the consumer level. FDM 3D printers work by extruding thermoplastic filaments, such as ABS (Acrylonitrile Butadiene Styrene), PLA (Poly...
The spray drying technique consists in a unit operation through which a liquid product, atomized with a hot air stream, is converted into a powder product through the evaporation of water present in the initial sample (Gharsallaoui et al., 2007). This technique is commonly used to produce da...
it forms the 3D object. This technology usually uses metals and alloys. It can even add material to existing parts, a capability not shared by most other 3D technologies. However, directed energy deposition can struggle to achieve as high a resolution as other methods. These 3D printers are ...
