What You Should Know About Casting Patterns

Casting is nothing but a manufacturing process where a liquid material is normally poured into a mold, which contains a hollow cavity of the desired shape, and is then allowed to solidify. The solidified SLA prototype parts are also known as casting, which is expelled or broken from the mold to complete the process. Casting patterns come in different types of materials which may include metal, plastics, wood, metal, and wax. This process includes SLA casting patterns and other techniques such as SLS casting patterns. Also, a pattern is nothing but a solid replica of the product that to be cast, but it is not always so. Utilizing the additive manufacturing methods for investment on SLS 3d printing service and casting patterns allows for more designs to be cast without the initial expense and time required to fabricate any tooling for patterns.

Stereo lithography - Casting Patterns

Stereolithography (SLA) is an additive process that uses a vat of liquid UV-curable photopolymer resin, and a computer controlled UV laser to build parts one thin layer at a time. The UV laser cures, or, solidifies the part layer and adheres it to each additional layer. When each layer is healed, the casting patterns of SLA machine lowers the platform with a single layer thickness, typically ranging from 0.002 "to 0.006". The casting patterns in SLA can also help in reducing costly errors by detecting design defects before the manufacturing process. The SLA prototype can be a cost-effective option for those who are looking for low volume production and also provide fast lead times. The benefit of SLA is that a functional part can be constructed in a relatively short period.

Selective Laser Sintering (SLS) - Casting Patterns

SLS technology is an advanced laser technology process that hardens and bonds small pieces of metal, plastic, ceramic, glass, and other materials. These materials are formed into layers in a 3D dimensional structure, and then SLS 3D casting patterns of each cross section of the 3D design is traced with the help of laser using the bed of powder on it. When the first layer is built, the lower and other layers are built on the existing layers. The major benefits of 3d SLS printing service are that it does not require the support of any structures like other AM technologies uses to prevent the design from collapsing at the time of production. As SLS parts are so robust, they equal those parts that have been produced by traditional manufacturing methods.

3D Polyjet Models - Casting Patterns

Polyjet parts are an excellent choice for applications that require a smooth and detailed master pattern to use when creating a repeatable mold for direct casting. Polyjet is a powerful 3D printing technology that produces smooth, precise parts, prototypes, and tools. With microscopic layer resolution and accuracy up to 0.1 mm, it can produce thin walls and complex geometries using the widest range of materials available with any technology. With this unique ability, you can print 3D Polyjet parts and assemblies made from materials of various models, with different mechanical or physical properties, all in one single construction. So you can order pieces of unmatched complexity, made of various materials and colors, and with the finish of a high-quality final product.

Well, Casting Patterns can provide quick and economical access to molds that are capable of low volume production which are normally built through the SLA, SLS, or Polyjet processes.
