“3D printing” or “Additive Manufacturing” takes digital input in the form of Computer Aided Design (CAD) model and creates solid, three dimensional parts through an additive process. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object

1984 - 86Charles Hull invents 3D printing and coins
the term “Stereo Lithography”
1992First 3D printer built by 3D Systems
1999First application of 3D printing in the
medical field - creating the human bladder
History
2000Miniature human kidney created through
3D printing
2006The Selective Laser Sintering machine –
printing multiple materials & fields
2009First usable prosthetic leg – this opens the
door for customized products using 3D printing
20113D printers start offering 14k gold as
printable material
A person creates a 3D image of an item using a computer-aided design
(CAD) software program.
The CAD information is sent to the printer.
The printer forms the item by depositing the material
in layers—starting from the bottom layer—onto a platform. In some cases
light or lasers are used to harden the material.

DESIGN
Printing System
Aerial Platform
The design was divide into the printing module and the mobility platform. The printing module delivers the material in a highly viscous form and deposits the material at the position of the printing nozzle. Using the quadcopter platform the robot can move to the required location and follow the path required to form the intended geometry by depositing material along its way

The two chemicals are stored in two separate containers. The containers used are two 5mL syringes which can also be used to pump the liquid out using the plunger. Manufacturing modifications have to be made to the syringes used in the system in order to reduce weight.
PRINTING SYSTEM LAYOUT01. Delivery
02. Mixing ComponentsThe two chemicals are mixed by joining the
flows with a custom design Y-splitter and pumping them through a disposable mixing nozzle
03. Reaction Chamber In order to provide more time for the two chemicals to react, the mixture is held in a reaction chamber until the mixture starts taking the required form
04. Nozzle Valve
Single valve acts as a printing head

INTEGRATION
Mounting
Dynamic Coupling of the Combined System
In order to mount the printing module on to the quadcopter.a rig was designed . The rig has two main functions, firstly itacts to attach the printing module to the base of the robot.The rig is designed such that there is a clearance betweenthe quadcopter’s legs and the base of the module. This isintended to prevent any damage to the module duringlanding or in the event of unexpected failure during flight.Secondly the rig also allows for the rotation of the printing
