Learn about many types of rapid prototyping

Rapid prototypes are basically manufactured in two different types, namely additive and subtractive. Like 3D printing, the addition process is a new form of prototype and function, which is achieved by creating layers layer by layer until the parts are completed. On the other hand, the subtraction process involves the use of primitive technologies such as milling. Both types of manufacturing technology can take hours and days to complete. However, each of these processes has many advantages.

3D printing
This is one of the processes of rapid growth and is popular mainly because of its affordable price. You can use 3D printing services at a fairly affordable price without spending a lot of time. 3D printing uses different techniques to create models. These systems are designed to provide maximum utility and effective results.

Stereolithography (SLA)
This is also one of the most traditional but most popular rapid prototyping services. It is mainly known for its strength, surface refinement and most importantly its cost. Stereolithography uses ultraviolet light to cure the liquid acrylic polymer layer by layer on a moving platform, and then undergoes multilayer curing to form the prototype of the preferred form. This process is carried out in VAT, a device filled with light-cured liquid acrylate polymer. Stereolithography is one of the most commonly used forms in rapid prototyping because it has precision (tolerance = 0.0125mm), takes less time (depending on the size and complexity of the part), the details of the part are fine and its geometry The shape is difficult to machine.

Selective laser sintering (SLS)
Selective laser sintering, or popular mainly under the name of SLS, is another popular form of rapid prototyping service. Compared with SLA, it is more expensive and the surface finish of the finished parts is high. Metals, ceramics, glass, plastics and many other materials are the main materials available.

Polyurethane casting
When multiple prototypes are required, the use of urethane castings is considered an economical method. The normal number is between ten and one hundred. These materials are available in a variety of materials and colors, thereby increasing customer revenue.

Therefore, these are some of the major rapid prototyping services. You can find many companies that provide such services there. You just need to make an informed choice and take full advantage of this modern technology.
