Rapid prototyping: a very promising method
Rapid prototyping is a method which makes it possible to produce a threedimensional model based on two-dimensional imaging. Various rapid prototyping methods are available for modelling, such as stereolithography, selective laser sintering, direct laser metal sintering, two-photon polymerization, laminated object manufacturing, three-dimensional printing, threedimensional plotting, polyjet inkjet technology, fused deposition modelling, vacuum casting and milling. The various methods currently being used in the biomedical sector differ in production, materials and properties of the three-dimensional model which is produced. Rapid prototyping is mainly used for preoperative planning, simulation, education, and research into and development of bioengineering possibilities.
