Rapid prototyping – is the creation of physical parts or models by layer by layer cultivation without instrumental production.

The advantages of rapid prototyping:

Production of models of any complexity with high accuracy;
Requires no tooling;
Significantly reduces the time from design to production;
Prototype let evaluate the appearance of the details;
Check the reliability of design, make the assembly;
Test the unit or part;
Reduce the costs of design and production preparation.

The main difference between this technology and traditional methods of production models is that the model has not been created by department the material from the work piece, as by-layer build-up of the material component of the model, including its constituent inner and even moving parts.

The building process is largely automated and can obtain high quality and relatively inexpensive model, spending on their production hours, not days and weeks, as when using traditional methods.

The models made by RP can be made of various materials (depending on the technology used in the equipment): a special powder, liquid resins, wax, plastics, and various sheet materials.

Materials.

Processes that use powdered materials carry out the bond particles by sintering by electron beam, laser beam or the selective application of binders.

The processes that use liquid consumables are divided into the processes of curing photopolymer by scanning laser beam (spot), using the mask (layer-by-layer), hybrid (inkjet print plus UV curing).

The processes that use solid sheet materials with thermal layer differ in the way of their cutting – laser or a cutter.

The processes that use the molten solid materials differ by the way of coating the material on the model: droplets of ink jet heads (wax), or cutting of plated head (ABS plastic, polycarbonate).

The scope of using Rapid Prototyping.

It allows you to obtain quickly (within a few hours) without a mold a physical prototype of plastic part that corresponds exactly to three-dimensional CAD-model.

Prototypes are used for: evaluation of ergonomics and appearance; evaluation of functionality as the master model.

The device operates at the office, does not require special laboratory.

The process is completely harmless to the environment and the operator.

After the modeling process the product can be used almost immediately, because it does not require long-term follow-up completion.

The scheme of work of technology FDM.

The principle of creating the models of prototype technology FDM (Fused Deposition Modeling) is fused to the layer-stacking semi liquid state of the polymer threads in accordance with the geometry of the details of the mathematical model developed in the CAD.

A mathematical model is transferred to the STL format in special software or Catalyst Insight, which will allow the operator to orient optimally it in the work zone of setup and automatically splits into horizontal layers.

Then it is determined automatically the need for supporting elements for the overhanging parts of the model.

The generated data is transferred to the installation and starts the process of creating the model layer by layer.

Have you ever faced the problem when you need to show your product but there is no model? Then definitely you require rapid prototyping. Moreover this technology can be very useful for marketing while the goods has not been produced yet. Fascinating? Go to this cheap rapid prototyping site.

This rapid prototyping methodology is a powerful instrument today. Take advantage of it to examine products, their weak and strong points. Also keep in mind that modern online technologies give you a unique opportunity to try and to find anything you might require. Should you want to keep abreast of new publications on the topic.
