What are 3D Prototyping Techniques?
3D prototyping techniques are a group of procedures that can quickly produce a tangible model of a product by using 3D CAD software. Another name for 3D prototyping is rapid prototyping. This process will create a solid physical structure of the product instead of a 2D layout. The prototypes can be used in different ways. For example, a visible image of the product can be use for communication and marketing purposes. As well as, a visual representation of the product can be used for testing and diagnostic purposes, tooling and rapid manufacturing. Rapid prototyping is made up of a few b[link widoczny dla zalogowanych] steps. The first step is creating a design model of the product by using computer aided design data. The next step involves converting the computer aided model design into a stereolithography form. The stereolithography form is chopped to develop a cross sectional model. This will create a constructed band and the band will be placed topmost of another band. The final step is a clean and finished model. Rapid prototyping has six 3D prototyping techniques" that involve a variety prototyping apparatuses. In addition, the prototype apparatuses are stereolithography, selective laser techniques, laminated object manufacturing, fused deposition models,[link widoczny dla zalogowanych], three dinensional inkjet printing and solid ground curing. Stereolithography is one of the first prototyping techniques. This technique uses liquid polymer which is photosensitive and solidifies with the use of an ultraviolet light. On the other hand,[link widoczny dla zalogowanych], stereolithography is considered to be the standard of rapid prototyping techniques. In 1988,[link widoczny dla zalogowanych], the stereolithography machine was built by 3D systems. One of the disadvantages of early stereolithography was that the model created from this method would produce a deformed and brittle model. The laminated object manufacturing technique was created with the Helisys machine. The process involves taking adhesive sheets and layering the sheets to create a prototype. In addition, the laminated paper is put together with a sticky substance and put on a spool. Laminated paper was one of the first substances used with this technique. Selective laser techniques are a method that was developed by Carl Deckard. Deckard created the method as a thesis project to complete his Master? s Degree. This method uses powdered metal, nylon and elastomer to make a solid object. Fused modeling is a technique that makes use of ejected thermoplastic filaments. The thermoplastic filaments are heated from the end. The tip moves on an x and y field range. The ground curing technique was developed by Cubital. Ground curing is similar to the stereolithography method. The technique involves using ultraviolets light that heats and harden the polymer. Solid ground curing and stereolithography is different because of the way the material hardens. The ground curing technique makes a complete layer of the product at a time. The techniques make it possible to create a quick prototype to meet important deadlines. Furthermore,[link widoczny dla zalogowanych], 3D prototyping techniques" are a fast way for businesses to create models to promote their brand.Topics related articles：
