3D Printing or 3-Dimensional Printing is a process of making a physical object from a digital
three-dimensional model. The object can be made using a few printing materials, including plastics,
powders, filaments, paper or even human tissue.
3D Printed Objects
Look at some 3D printed objects around the world.

BLOCKCHAIN
Blockchain is a decentralised system of recording information that makes it nearly impossible to alter,
hack, or cheat the system. Blockchain can be used in businesses where data integrity, transparency,
and traceability are essential. It is a shared ledger that records transactions and tracks assets (tangible
or intangible) within a business network. Tangible assets include houses, cars, cash, land, etc., and
intangible assets involve intellectual property, patents, copyrights, branding, etc.
The blockchain duplicates and distributes a digital ledger of transactions across the entire network of
computers. Each block within a chain stores a cryptographic hash of the previous block, timestamp,
and transaction data, ensuring immutability. This record of every transaction is updated and added
to the participant’s ledger after consensus is reached. A blockchain network can record, track, and
trade anything that carries value.
