3D printers use additive manufacturing to build solid objects layer by layer using materials like powdered resin, metal, or paper. CAD software is used to design objects which are then printed by 3D printers. There are different types of 3D printing technologies like direct 3D printing which uses inkjet printing techniques and binder 3D printing which binds powdered materials. 3D printing enables the creation of complex geometries and is used across industries like aerospace, automotive, robotics, and education.

3D printing is a process of making a three -dimensional solid objects from a digital file using additive manufacturing techniques. In this process layers of material are successively deposited one above the other to create an object. Each layer can be visualized like thinly sliced section of the object. The key to this 3D printer is the thermoplastic extruder which is coupled with a Cartesian XYZ platform. 3D printing by using PLA filament electronics are based around the popular Arduino development platform,utilizing a custom made board for interfacing with the Arduino development Board and allowing stepper motor and extrusion temperature monitoring and control. In very simple terms,3D Printer (not to be confused with printers we see in everyday life) is electromechanical device that builds physical object with very high precision(100 micron or .1mm) at a very low cost.
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

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

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
1. 3D Printers
3D PRINTERS are primarily used in COMPUTER-
AIDED DESIGN (CAD) applications.
• They can produce solid objects which actually
work.
• The solid object is built up layer by layer
• using materials such as powdered resin,
powdered metal, paper or ceramic powder.
2. COMPUTER-AIDED
DESIGN
• Computer-aided design is the use of
computers to aid in the creation, modification,
analysis, or optimization of a design.
• CAD software is used to increase the
productivity of the designer, improve the
quality of design, improve communications
through documentation, and to create a
database for manufacturing.
3. Examples of CAD software
• AutoCAD, 3ds Max, and Maya —
commercial CAD software titles published by
Autodesk.
• Blender — an open-source CAD, animation,
and image processing application with an
active community of users.
• Sketch Up — a proprietary CAD application
that runs in a web browser, formerly
developed by Google.
4. CAD( COMPUTER-AIDED DESIGN)
• CAD, or computer-aided design, is a form
of computer technology that assists in the
drawing and technical drafting of products
and even buildings. ... In order to generate the
actual model, CAM works alongside CAD—
using CAD designs, CAM uses numerical
coding to run the machine that creates the
product.
5. Why is CAD better than drawing by
hand?
These tools also help in producing designs with
high accuracy like in Shop Drawings and the
scope for errors is much lower when compared
to hand drawing.
Modifying the CAD geometry is easy with all the
tools available. Correcting any errors is much
quicker when compared to using a pencil and
paper.

7. FEATURES OF 3D PRINTING:
3D printers use
• ADDITIVE manufacturing
• SUBTRACTIVE manufacturing
• CNC machining
• Direct 3D printing uses inkjet technology;
• Binder 3D printing is similar to direct 3d
printing
8. 3D printers use ADDITIVE
manufacturing
• Additive manufacturing, also known as 3D
printing, is a transformative approach to
industrial production that enables the
creation of lighter, stronger parts and systems.
It is yet another technological advancement
made possible by the transition from analog
to digital processes
9. What materials can be used in
additive manufacturing?
• Three types of materials can be used in
additive manufacturing: polymers, ceramics
and metals. All seven individual AM processes,
cover the use of these materials, although
polymers are most commonly used and
some additive techniques lend themselves
towards the use of certain materials over
others.
10. What is an example of additive
manufacturing?
• 3D printing is one form of AM. ...
Additive manufacturing uses data computer-aided-
design (CAD) software or 3D object scanners to
direct hardware to deposit material, layer upon
layer, in precise geometric shapes.”
• “As its name implies, additive
manufacturing adds material to create an object.
12. SUBTRACTIVE manufacturing
• What is subtractive manufacturing? Definition and
examples
• Subtractive manufacturing or subtractive fabrication
involves cutting away from a solid block of material. It
could be a block of, for example, metal, plastic, or
wood. A milling machine cutting/hollowing out a piece
of metal or plastic is an example of subtractive
manufacturing.
• Subtractive manufacturing by manually cutting the
material is also possible. In fact, before the industrial
revolution, that was how most of it was done.
15. CNC MACHINING
The term CNC stands for
computer numerical
control and the CNC
machining definition is
that it is a subtractive
manufacturing process wh
ich typically employs
computerized controls
and machine tools to
remove layers of material
from a stock piece—
known as the blank or
workpiece—and produces
a custom-designed part.
16. Direct 3D printing
https://www.youtube.com/watch?v=dGajFRaS834
• Direct 3D printing uses inkjet technology.
• Direct 3D printing employs jet techniques,
which is used in 2D printing since the 1960s.
Just as in a 2D printer, nozzles of a 3D
printer move to and from to distribute the
liquid. However 3D printer nozzles or
the printing side go up- and downward, so lots
of layers over the same surface appear.
17. Applications of Direct 3D Printing
• Five Industries Utilizing 3D Printing
• Aerospace. The aerospace industry has some of
the highest standards in part performance. ...
• Automotive. The automotive industry has been
charging ahead with additive manufacturing, with
high-profile companies such as Audi using 3D
printers. ...
• Manufacturing. ...
• Robotics. ...
• Education.
