Method of rapid prototyping (rapid prototying) is based on the principle of building material layers corresponding to 3D models using 3D printers. This process should be done with the design data, that has been completed and transferred to the STL format (Stereolithography) and enter the 3D printer, which will be automatically processed and distributed models are created in layers to form.

Rapid Prototyping Technology

Many prototyping technology includes SLS (Selective Laser Sintering), SLM (Selective Laser Melting), FDM (Fused Deposition Modeling). Each technology has advantages and disadvantages.

  • SLS – Selective Laser Sintering: is an additive manufacturing  technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. (Wikipedia)
  • SLM – Selective Laser Melting: is an additive manufacturing process that uses 3D CAD data as a digital information source and energy in the form of a high-power laser beam, to create three-dimensional metal parts by fusing fine metal powders together. Manufacturing applications in aerospace or medical orthopedics are being pioneered. (Wikipedia)
  • FDM – Fused Deposition Modeling: spray method using molten material was to make detailed models for demanding not too elaborate. This is the economical solution for small-scale plants and the method is widely used and most popular today. Most of the 3D printers in the market are using this method of prototyping.

3D design softwares

3D printing technology offers great promise for anyone who wishes to create products that allows printing of models, toys, daily use products, or other body parts or even entire a house . 3D printers can create anything; however, for those who are beginners and they need to get used to the 3D design software called CAD (Computer Aided Design) or other design software, such as on a sketches before print prototype. One thing to note, that when importing 3D design file to the printer and should be the default in .STL format for 3D printers can read understands your drawings.

3D printing material loaded into the machine

After you have completed the 3D design, it’s time you started to print them out finished products. 3D printing process is not too complex as we often think. The current 3D printers use ABS or PLA are mainly two types of materials, in addition to others such as metal or glass. With the use of 3D printers, users will mount plastic plastic cord to the print head, it is shaped a square box with a nozzle. Actuators in the nozzle will automatically put plastic down the nozzle. Simultaneously with the heat pipe section and liquefied before extrusion plastic fiber out of the printhead. Plastic passing the print head is about the size of super-piece just 0.1mm and dry fast, be adhesive together in layers.

3D printer-The principle of operation

3D printers operates on the principle in accordance with the coordination layer of surface printed (in bed) and the nozzle to perform spatial modeling 3D. Thanks to a system of vertical sliders and horizontally, the nozzle can move according translational and combined with suspension, fully nozzle can move up and down in 3-dimensional space.

Most 3D printers now have one nozzle, which can only create a color for the final product. If you want more color objects, they must adjust and change other color plastic fibers during the printing process. 3D printing technology is still in the process of development and improvement, promises to bring to market the machines capable of blended yarn for printing plastic objects diverse in color.

3D printing process can take place in minutes, hours or even days depending on the size and quantity of product archives.

Maximize performance implementation of ideas

Rapid prototyping with 3D printers is how to turn ideas become the most intuitive process to optimize communication between the designer and producer. Models were produced in a short time to help design teams can evaluate designs, thereby adjusting the potential errors easily than observed on the 3D model.

Clear visibility of the product model is convincing for customers while presenting design, help increase customer confidence in the selection process and product pricing. Also, the method of rapid prototyping 3D printer also saves the cost and shorten the time to introduce new products to the market.
