Urethane casting is a fast and cost-effective method of producing small series from a silicone mold. A silicone mold is made with the help of a prototype which serves as the basis for the duplication process of the original piece. Thanks to the flexibility of the silicone, complex intermeshing geometries can be achieved without demoulding problems. The base material used for the reproductions is a liquid polyurethane resin which with the use of additives can simulate the properties of a wide variety of plastics. Between 15 and 30 parts can be produced depending on the requirements of the material and surface finish. This method is ideal for the production of small batches and prototypes in which the production of expensive injection molding tools is not feasible.

Stereolithography (SLA or SL; also known as optical fabrication, photo-solidification, solid free-form fabrication and solid imaging) is an additive manufacturing or 3D printing technology used for producing models, prototypes, patterns, and production parts up one layer at a time by curing a photo-reactive resin with a UV laser or another similar power source.

Selective laser sintering(SLS)is an additive manufacturing technique that uses a laser as the power source to sinter powdered materila(typocally metal or polymer), aiming th laser automatically at points in space defined by a 3D mode., binding the material together to create a solid structure. It is similar to direct metal laser sintering(DMLS);SLS (as well as the other mentioned AM techniques) is a relatively new technology that has mainly been used for rapid prototyping and for low-volume production of component parts so far. Production roles are expanding as the commercialization of AM technology improves.

Sheet metal cutting can be done in various ways, from hand tools called tin snips up to very large powered shears. With the development of technology, sheet metal cutting has turned to computers for precise cutting. Many sheet metal cutting operations are based on computer numerically controlled (CNC) laser cutting or multi-tool CNC punch press.
