The difference between 3D printing and rapid prototyping


First, definitions,

Definition of rapid prototyping:

Rapid Prototyping (RP), born in the late 1980s, is a new technology based on material stacking method, which is considered as a major achievement in the field of manufacturing in the past 20 years.It set of mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, laser, can automatically, and directly, quickly and accurately will prototype design ideas into a certain function or directly make parts, prototyping, a new design idea for parts of calibration etc. Provides a highly efficient low cost means of implementation.

Definition of 3D printing:

3D printing, which emerged in the mid-1990s, is actually the latest rapid prototyping device using technologies such as photo-curing and paper lamination.It works basically the same as ordinary printing. The printer contains liquid or powder and other "printing materials". After connecting with the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a physical object.This is called 3D printing.

At present, the domestic media industry is used to call rapid prototyping technology as "3D printing" or "3D printing", which is quite vivid, but in fact, "3D printing" or "3D printing" is only a branch of rapid prototyping and can only represent part of the rapid prototyping process.


Second, the difference between

A 3D printer is a simple version of a rapid prototyping machine.Less loss, less ability.

Rapid prototyping has been a routine approach in the automotive and aircraft industries for years.

In general, 3D printers are compact and smaller than RP machines.They're perfect for the office.They use less energy and less space.They are designed for low-volume renderings of real objects made of nylon or other plastics.This also means that 3D printers make smaller parts.

The rapid prototyping machine has at least a 10-inch building chamber on one side, and the 3-d printer has less than eight inches on the side.However, 3D printers can perform all the functions of a rapid prototyping machine, such as verifying and validating designs, creating prototypes, and sharing information remotely.


As a result, 3D printers are easy to process and easy to maintain.You can buy these DIY kits on the market and build your own.It's cheaper than a professional rapid prototyping machine, and you can get a 3D printer for under $1,000.Professional rapid prototyping designs cost at least $50,000.

A 3D printer is not as accurate as a rapid prototyping machine.Material selection is also limited by its simplicity.
