Rapid prototyping takes a virtual 3D CAD model and builds a physical model layer by layer using materials like liquid, powder, or sheets. It can create almost any shape and is used for prototypes, models, production parts, and art. The process involves transforming the virtual design into cross sections, then creating each cross section physically with an additive fabrication machine by laying down successive layers that fuse together. While construction times can vary widely, additive systems can typically produce models in a few hours.
3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object ,with material being added together (such as liquid molecules or powder grains being fused together), typically layer by layer. In the 1990s, 3D printing techniques were considered suitable only for the production of functional or aesthetical prototypes and a more appropriate term was rapid prototyping
Three-dimensional (3D) printing is an additive manufacturing process that creates a physical object from a digital design. The process works by laying down thin layers of material in the form of liquid or powdered plastic, metal or cement, and then fusing the layers together.

Additive manufacturing, commonly referred to as 3d printing, is a manufacturing
technique that rises in the 1980’s mainly focused on engineering prototyping. Current
advances in the precision and cost of the techniques, as well as the widespread use of 3d
designing have increased 3d printing’s scope of use from high-end engineering prototypes
to a large variety of uses in manufacturing. 3d printing improve the processing time,
decrease waste, and increase the level of customization of certain products by eliminating
the need for the specialty tooling and dies that are traditionally used in manufacturing. In
addition, the ability to physically print difficult shapes based on a computer model has
given rise to new products that would otherwise be simply impossible to create. The
various fields have taken advantage of this technology by printing 3d objects.
Industrial adoption of 3D Printing has been increasing gradually from prototyping to manufacturing of low volume customized parts. The need for customized implants like tooth crowns, hearing aids, and orthopedic-replacement parts has made the life sciences industry an early adopter of 3D Printing. Demand for low volume spare parts of vintage cars and older models makes 3D printing very useful in the automotive industry. It is possible to 3D print in a wide range of materials that include thermoplastics, thermoplastic composites, pure metals, metal alloys and ceramics. Right now, 3D printing as an end-use manufacturing technology is still in its infancy. But in the coming decades, and in combination with synthetic biology and nanotechnology, it has the potential to radically transform many design, production and logistics processes.

Rapid Prototyping
Also known as solid freeform fabrication, rapid prototyping is a technology that takes a virtual
design (3D CAD models) and transforms the object into cross sections (layers). The RP software
then creates each cross section laying down successive layers of liquid or other type of powdered
material that will fuse together and solidify to create the final shape which represents an almost
identical model.
2. Rapid prototyping is the automatic construction of physical objects using solid freeform
fabrication. The first techniques for rapid prototyping became available in the late 1980s and
were used to produce models and prototype parts. Today, they are used for a much wider range
of applications and are even used to manufacture production quality parts in relatively small
numbers. Some sculptors use the technology to produce complex shapes for fine arts exhibitions.
Rapid prototyping takes virtual designs from computer aided design (CAD) or animation
modeling software, transforms them into thin horizontal cross sections, still virtual, and then
creates each cross section in physical space, one after the next until the model is finished. It is a
WYSIWYG process where the virtual model and the physical model correspond almost
identically.
With additive fabrication, the machine reads in data from a CAD drawing and lays down
successive layers of liquid, powder, or sheet material, and in this way builds up the model from a
series of cross sections. These layers, which correspond to the virtual cross section from the
CAD model, are joined together or fused automatically to create the final shape. The primary
advantage to additive fabrication is its ability to create almost any shape or geometric feature.
The standard data interface between CAD software and the machines is the STL file format. An
STL file approximates the shape of a part or assembly using triangular facets. Tiny facets
produce a higher quality surface.
The word "rapid" is relative: construction of a model with contemporary methods can take from
several hours to several days, depending on the method used and the size and complexity of the
model. Additive systems for rapid prototyping can typically produce models in a few hours,
although it can vary widely depending on the type of machine being used and the size and
number of models being produced simultaneously.
Some solid freeform fabrication techniques use two materials in the course of constructing parts.
The first material is the part material and the second is the support material (to support
overhanging features during construction). The support material is later removed by heat or
dissolved away with a solvent or water.
Traditional injection molding can be less expensive for manufacturing plastic products in high
quantities, but additive fabrication can be faster and less expensive when producing relatively
small quantities of parts.
A large number of competing technologies are available in the marketplace. As all are additive
technologies, their main differences are found in the way layers are built to create parts. Some
are melting or softening material to produce the layers (SLS, FDM) where others are laying
liquid materials thermosets that are cured with different technologies (SLA, MJM, PolyJet). In
the case of lamination systems, thin layers are cut to shape and joined together.
