Possibly from the Calima culture (100–500 AD) Golden mask of Tutankhamun 's mummy. Repoussé (French: [ʁəpuse] ⓘ) or repoussage ([ʁəpusaʒ] ⓘ) is a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing (French: ciselure) or embossing is a similar ...
model/x.stl-binary. Developed by. 3D Systems. Initial release. 1987. Type of format. Stereolithography. STL is a file format native to the stereolithography CAD software created by 3D Systems. [3][4][5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography.
If using a 3D Printed pattern proceed directly to step 5. Create a mould: A mould, known as the master die, is made to fit the master pattern. If the master pattern was made from steel, the master die can be cast directly from the pattern using metal with a lower melting point. Rubber moulds can also be cast directly from the master pattern ...
Metal casting. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue.
A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries. A periodic tiling has a repeating pattern. Some special kinds include regular tilings with regular ...
Selective laser melting (SLM) is one of many proprietary names [1] for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF). PBF is a rapid prototyping, 3D printing, or additive ...
Bending (metalworking) Bending. A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
Shell molding was developed as a manufacturing process during the mid-20th century in Germany. It was invented by German engineer Johannes Croning. [3][4] Shell mold casting is a metal casting process similar to sand casting, in that molten metal is poured into an expendable mold. However, in shell mold casting, the mold is a thin-walled shell ...
