3D scanning involves analyzing and collecting data about a real object's shape and appearance to build a digital 3D model. It works by using a laser line and camera to capture images of an object's surface from different angles. The images are then combined to form point clouds depicting the object's geometric features. 3D scanning has applications in reverse engineering, entertainment, cultural artifact documentation, and face scanning. 3D printing involves layer-by-layer deposition of material according to a digital 3D model to physically create an object. It has uses in manufacturing, medical procedures, research, product prototyping, construction, and more. The presenter proposes integrating 3D scanning and printing further, such as by adding a touchscreen to

2. 3DSCANNING:-
 3D Scanning is a process of analyzing and collecting
data of real object; its shape and appearance and
builds digital, three dimensional models.

3. HOW DOES IT WORK….
A laser pointer formed into a line and aimed into the
object, this laser line will take the outer shape of the thin
part of object at this moment a camera positioned at a
known angle captures an image of the object.

4. Working…..
 This is the laser based diagram.

5. Pointcloud-
 3D scanners usually creates a point cloud of
geometric samples on the surface of the
subject.These points can then be used to
show the shape of the subject.

6. Applications-
 Used in Reverse Engineering Process.
 Entertainment industry in the production of
movies and video games
 Inspection and documentation of cultural
artifacts.
 Face Scanner:

7. Whatis3DPrinting…?
 3D printing is a form of additive
manufacturing technology where a three
dimensional object is created by laying down
successive layers of material.

8. Digital Fabrication
- it takes a model
└a digital design
└turn into real, physical Object
Whatis3DPrinting…?

9. HistoryOf3dPrinting
 The technology for printing physical objects from digital
data was first developed by Charles Hull in 1984.
 The technique was STL(stereo lithography)
 In 2005,Z Corp,launched a breakthrough product, named
spectrum Z510, which was first high definition color printer
in market.

14. 3DPrintingUses-
• Medical procedures
• Advances in research
• Product prototyping
• Historic Preservation
• Architectural Engineering Construction
• Advanced Manufacturing
• Food Industries
• Automotive
• Accessories

15. MedicalProcedures-
• Custom hearing aids and braces.
• Body parts, including ears, hips and even
organs, in exact proportions to fit the patient.
• In February 2012, surgeons successfully
implanted an entire titanium jaw, made with
3D printing, in an elderly woman.

16. 3dprinting-MakeinINDIA
 Even a house wife/potter/a comman man can start
his own business in India with this technology.
 Replicating ancient and priceless artifacts in
archaeology.
 Reconstructing bones and body parts in india itself
 Making parts on the fly. Applications for space offer
the ability to print broken parts
 Eg- Nasa has made socket of a aircraft using 3d
printer

17. MyPointhowitcanbeevenmorebetter-
 We can put an small flip screen(lcd) with android
device in printing machine and can connect with
the hand scanner via bluetooth & directly scanned
data can be proscessed to the 3d printer
 Advantages- it will reduce the time and will not
need laptop or computer.
 From one country to another;objects can be
printed.
 Disadvantage- it will be costlier,may lose data.
