The many advantages of rapid prototyping have made the services popular and highly sought after. There are manufacturing companies that offer services to meet the specific needs and requirements of the customer. However, rapid prototyping involves a number of different techniques to make the necessary models for customers, and below are some of the most common techniques in the industry today.

SLA stands for stereolithography and is a process that revolves around the selective polymerization of photosensitive resins using ultraviolet light. A laser beam is placed on a resin that is photosensitive and has a tank such that it polymerizes within the limits of the cross-section before the cured polymer layer is lowered to allow a fresh liquid resin to cover it. This technique comes with the advantage of giving high details and a good surface finish, as well as precision for different industries.

SLS - stands for Selective Laser Sintering and is among the most common rapid prototyping services and techniques available today. The technique has a high powered laser beam that melts and fuses dispersed powder materials into one layer. A rotating roller is used on a table to spread the powder in precise and measured amounts before the fusion takes place. Produces porous fabricated prototypes that deteriorate surface finish and strength. It is also a process that can handle a variety of materials and no post cure is required, minimizing construction time.

FDM: This is a fused deposition model, which is based on melting and depositing fine cross-hatched thermoplastic polymer filaments to form partial layers. A wire material is supplied on sealed reels which are then mounted on a machine before threading it through the FDM head. This head is then moved horizontally to produce layers in zigzag movements. The technique does not require any subsequent curing and can work with various materials. It is also inexpensive and offers an easy material changeover that gives the manufacturer easy time to work with different materials depending on the project in question.\

Other techniques used in rapid prototyping are three-dimensional printing and LOM, which stands for fabrication of laminated objects. The project in question determines the technique used by the prototype manufacturer and also the customer's requirements. However, it is very important to remember that although each of the techniques has advantages, each has its own disadvantages. It is important to weigh your options and look carefully at the technique you are choosing to ensure you get the best for your needs.

If you are not very familiar with rapid prototyping, your manufacturing professionals should be able to guide you through the basics to at least help you better understand the processes and help you make a decision about the techniques and materials that are obtained. used for your desired prototypes. The more you know about the processes, the better your position will be to make good decisions.
