What is the fused deposition modeling ™?

Flused Deposition Modeling ™ (FDM®) is a computer production process for making three -dimensional parts. The device is created in detail by repeatedly by layering melting thermoplastic formation of the desired shape. Modeling deposition can create plastic parts for testing without the production of medium parts made of clay or resins. This process is also useful for creating specialized or low -volume parts without having to create tools or forms, saving time and costs. This file is entered in the FLUSED DEPOSITION MODELING ™, which uses the software to control the nozzle head. The mellable plastic is continuously fed into a nozzle that warms the plastic only to its melting point. The softened plastic is placed on the tray inside the modeling device as a number of very small dots that harden quickly.

The nozzle responds to the Moving computer program in two dimensions called the X- and Y axis. Plastic continuously fed is placed according to software on points that correspond to the product of the product withophtware. Once the slice is completed, the nozzle moves vertically by a very small amount and another cut is stored. This process continues until the part is fully invented.

different processes can create parts using techniques of modeling deposition. Stereolithography uses laser and resin sensitive to light to form parts. Parts of the resin may not have the same structural power as parts made of fused deposition ™ modeling, but are useful as prototypes. Metal parts can be made using direct metal laser salivation, which melts a fine metal powder in high -performance layers.

For modeling of fused deposition ™ is available a number of thermoplastic resins. Butadien Styren acrylonitril is commonly used due to its thermal properties, low costs and strength of finished parts. Other thermoplastics that can be used in FDM® include polycarbonates, polycapRolledons and polyphenylsulphones. The choice of plastic depends on whether strength, high temperature or combination of both are required for the finished part.

Deposition Modeling and other deposition processes are sometimes referred to as immediate parts. In fact, this is not the case, because the materials must be stored in very fine layers to build part. Creating a part or shape can take hours or even days depending on the complexity of the design. The advantage of using FDM® technology is that one piece can be made directly from a computer drawing. Changes in design can be easily made and another piece can be made immediately from the drawing.
