Product development is a broader term and product design is a part of product
development. Product development involves a lot of activities. It starts from market
analysis, Marketing, sales, customer support and finishes at the end of the product life cycle. In this
article, we will discuss the difference between product design and product development.
Product Development includes a complete product development cycle. It starts
from market analysis followed by product specifications, concept/industrial
design, product design, costing, scheduling, testing, manufacturing, logistics,
customer feedback, improvements and all other aspects of getting a product into
The complete product development process involves marketing, design, purchase,
manufacturing, sales, and after-sales support teams.
Product Design process involves mostly technical work. It involves product
concept design, user experience, architecture design, mechanical design,
electrical and electronics design, firmware development, design calculations,
simulation and product testing.
A good product design ensures, product working as per design specifications and
within target cost.
What is Rapid Prototyping?
Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a
physical part or assembly using three-dimensional computer aided design (CAD) data.
Construction of the part or assembly is usually done using 3D printing or "additive layer
manufacturing" technology, where,
Prototype: It is a model fabricated to prove out a concept or an idea.
Solid Modelling: It’s a branch of CAD that produces 2D or 3D objects in an electronic
Definition: Rapid prototyping is basically a additive manufacturing process
used to quickly fabricate a model of a part using 3-D CAM data.
It can also be defined as layer by layer fabrication of 3D physical models directly
What are the different types of rapid prototyping?
There are new additive manufacturing techniques being developed all the time.
Some are best for consumer applications and others for industrial environments, but not
all of them are suited for rapid prototyping. Let’s take a look at the top 7 methods for 3D
prototyping and their strengths and weaknesses so that you can decide what might be
best for your next project.
Stereolithography was the first successful commercial 3D printing method. A bath of photosensitive
liquid is solidified one layer at a time using a UV light controlled by a computer. These layers are
derived from two-dimensional cross sections of the 3D CAD model and controlled with a software
file format called .stl.
