3D printing is an additive manufacturing process that creates physical objects from digital designs by adding material layer by layer. There are several methods for 3D scanning objects to create digital models, including photogrammetry which uses photographs from different angles to stitch together a 3D image, and laser scanning which measures the angle of reflected lasers to determine object coordinates and create a 3D mesh. 3D printing began development in the 1980s and has since progressed to enable applications like medical implants, prosthetics, and even 3D printed cars.

manufacturing process that creates
a physical object from a digital
design. A digital model is turned
into a solid three- dimensional
physical object by adding material
layer by layer.

SCANNING

7. TYPES NO.1
The method is based on taking 2D pictures around an object,
from different angles, and stitching
them together into a single 3-Dimensional image. The last part
being handled by software.
123D Catch, Dimensional, or Trio are all great apps for this. The
software will match all overlapping points of the images and
create a 3D model.
PHOTOGRAMMETRY

8. TYPES NO.2
send patterns of light onto
the object to capture. Based
on the deformations of the
pattern it determines the
model form and creates a
3D mesh, or digital replica
LIGHT SCANNING
STRUCTURE SCANNING LASER SCANNING
measures the angle of the
reflected lasers which it can
translate into coordinates of
an object and therefore into
a 3D mesh.

9. 1. Quickly capture all of the physical
measurements of any physical object.
Save time in design work.
2. Ensure parts will fit together on the first try.
Capture engineering optimizations inherent
in manufactured parts.
3. Utilize modern manufacturing on parts that
were originally manufactured before CAD.
4. Compare “as-designed” model to “as-built”
condition of manufactured parts.

11. Journey of 3D
Printing Technique
 3D Printing seems to be a new technology, but in actual started arising from 1980. This took a long way to develop and come
in to the form of today.
 Here is the recap of revolution in 3D technique and it’s uses:-
 1980: first patent by Japanese Dr Kodama Rapid prototyping
 1984: Stereolithography by French then abandoned
 1986: Stereolithography taken up by Charles Hull 1987: First SLA-1 machine
 1988: First SLS machine by DTM Inc. then buy by 3D system 1990: First EOS Stereos system
 1992: FDM patent to Stratasys 1993: Solidscape was founded
 1995: Z Corporation obtained an exclusive license from the MIT 1999: Engineered organs bring new
advances to medicine 2000: a 3D printed working kidney is created
 2000: MCP Technologies (an established vacuum casting OEM) introduced the SLM technology 2005: Z Corp. launched Spectrum Z510.
It was the first high-definition color 3D Printer
 2006: An open source project is initiated (Reprap)
 2008: The first 3D printed prosthetic leg 2009: FDM patents in the public domain
2009: Sculpteo is created
 2010: Urbee is the first 3D printed prototype car presented 2011: Cornell University began to build 3D
food printer.
 2012: The first prosthetic jaw is printed and implanted
 2013: “3D printing” in Obama’s State of the Union speech
 2015: Carbon 3D issues their revolutionary ultra-fast CLIP 3D printing machine 2016: Daniel Kelly’s lab announces
being able to 3D print bone
