Rapid prototyping include the methods used to create a new system, object or product model quickly.

It is usually done with  3d images created with CAD software and uses a 3D printer to make the components quickly.


A Rapid Prototyping is a group of techniques used to quickly prepare the scale model of the physical part or assembly using three-dimensional computer-aided design (CAD) data.

Construction of Part or assembly is usually done using 3D printing or “Additive layer manufacturing” technology.

The common form of Rapid Prototyping

forms of rapid Prototyping

There Are 4 main  forms of rapid prototyping technologies for Additive manufacturing process :

1.Fused Deposit Molding (FDM)

Fused Deposit Molding

 FDM is one of the more popular methods of RAPID PROTOTYPING.

This allows you to create many different types of plastic parts.

Polymer printing allows a variety of flexible and rigid materials. This Also known as 3D printing

2.Stereolithography (SLA)

Stereolithography (SLA)

SLA is a UV treatment of resin technique which is more expensive but gives a great finish and can give you a much more transparent part.

SLP uses a more traditional light source.

3.Selective laser sintering (SLS)

Selective laser sintering (SLS)

SLS  is involved with the layer with the heating layer of metal or plastic powder particles.

Good for complex metal parts, but will be roughly finishing and will not be great for small hollow parts.

There are also subtraction procedures like manual hot wire cutting for foam.

CNC machining extends parts from the block of hard material like wood, foam, and plastic.

4.Laminate object manufacturing (LOM)

Laminate object manufacturing (LOM)

which consists of a layer of wood/laminate and the machine cuts a pattern and then bounces glowing next to the top and then bites again.

This repeated over and over again until the object in formed

Hand building with adhesive, cutting wire, saw, precision knife, Dremel drill etc. are also a way of

All 3D printing begins with the filament of various materials to create an object layer by layer, which is drawn in the 3D file.
