2. INTRODUCTION
• 3D printing is a modern technology in which
3 dimensional objects are printed from
digital data
• Three dimensional object is created by
laying down successive layers of material
• It is a additive manufacturing technology
3. HISTORY
1.The technology for printing physical 3D objects from digital data was first
developed by Charles Hull in 1984. He named the technique as Stereo lithography
and obtained a patent for the technique in 1986
2..Fused Deposition Modeling (FDM) and Selective
Laser Sintering (SLS) were introduced.
In 1993
3. In 1996, three major products, "Genisys" from Stratasys, "Actua 2100" from 3D
Systems and "Z402" from Z Corporation, were introduced
4. In 2005, Z Corp. launched a breakthrough product, named Spectrum Z510, which
was the first high definition color 3D Printer in the market.
5.in 2006 with the initiation of an open source project, named Reprap,
which was aimed at developing a selfreplicating 3D printer.
14. Stereolithography
• Stereolithography is an additive manufacturing process by using
liquid UV-curable photopolymer ”resin” and a UV laser to build
parts a layer at a time.
15.
16. Selective laser sintering (SLS)
• Selective laser sintering (SLS) is an additive
manufacturing technique that uses a high
power laser to fuse small particles of plastic,
metal (direct metal laser sintering),ceramic or
glass powders into a mass that has a desired
3-dimensional shape
17.
18. Fused deposition modeling (FDM)
• Commonly used for modeling, prototyping, and
production applications.
• Here a hot thermoplastic is extruded from a
temperature-controlled print head to produce
fairly robust objects to a high degree of accuracy.
19.
20. Laminated object
manufacturing
Laminated object
manufacturing (LOM)
is a rapid prototyping
system developed by
Helisys Inc. In it, layers
of adhesive-coated
paper, plastic or metal
laminates are
successively glued
together and cut to
shape with a knife or
laser cutter.
21. Ink-Jet 3D Printing
It creates the model one layer at a time by
spreading a layer of powder and inkjet printing
binder in the cross-section of the part.
It is the most widely used 3-D Printing technology
these days
23. Powder
The material used for 3D printing is powdered as per
requirement
A good powder should have good depositability
Powders are deposited in both dry & wet condition
Dry deposition(20 microns and above)
Wet deposition(below 5 microns)
Microscopic shape of the powder also having significants
Spherical powder gives good flow rate
Additives can be used along with Powder to enhance
printing
eg:Lecithin,Graphites,Ceramics
Powder is depositing on bed by horizontal vibrating blades
Traversing doctor blade
Rotating sieve drums
24.
25. Binders
Binder is a glue used to bind the
powder together to produce required
shape
Binder is selected with respect to the
chemical and physical properties of
powder
It will strenghthen the structure after
post processing
26. Classification Of Binders
The binders are classifies according to their chemical properties and mode
of action
Organic Binders
They are thermally react with specific gaseous and form binding action
Eg:Butyral resins,Polymeric resins,polyvinyls
In bed adhesives
They bind the powder after interacting with deposited liquids and
dehydrated on heat treatment
Eg:Maltodextrin & Sucrose
Hydration System
Binding action can be activated by adding water,they bind together at wet
condition.
Binding behaviors can be controlled by catalysts
Eg:Plasters,Ciment
27. Acid-base System
This knid of binders binds most of the materials
Binding is generated through Acid-Base chemical reaction
Eg:Electrolyte coating of polyvinyl pyrrolidone
Inorganic Binders
They are mainly silica compounds
When treated with CO2 or acids the powder get binded by colloidel gel of
silica and it also gives strength after post processing.
Eg:Colloidal Silica Solution(PH 9-9.5)
Metal Salts
They are mainly used to bind metal powders
Binding carried our by the recrystallization of metal salts.
Eg: Silver nitrate Salt(reduced to cilver at 4400C )
Copper Sulphate(For steel)
28. Solvents
Solvents dissolves particles or nearly all of the particles if it comes in contact
When the solvents evaporates polymers get precipitated and get binds
Eg:Chloroform used to bind polyesters and plastics
Phase-Changing Materials
This kind of binders melts at high temperature and get solidifies at room
temperature and form bonds between printing powders
Eg: 2-Methyl propane-2-OL
29. Print Head
Industrial inkjet printing essentially means using inkjet
technology as a printing or deposition process in
manufacturing or on production lines
While all inkjet technologies can fundamentally be described
as the digitally controlled ejection of drops of fluid from a print
head onto a substrate, this is accomplished in a variety of
ways.
There are 2-types of print head for the generation of liquid
drops
Drop-On-Demand (DOD)
Continuous-Jet (CJ)
30. DOD Print Head
Drop on demand (DOD) is a broad classification of inkjet printing technology
where drops are ejected from the print head only when required.
The drops are formed by the creation of a pressure pulse within the print head.
32. Thermal DOD
drops are formed by rapidly heating a resistive element in a small chamber
containing the ink.
33. Piezoelectric DOD
a piezoelectric crystal (usually lead zirconium titanate) undergoes distortion when
an electric field is applied. This distortion is used to create a pressure pulse in the
ink chamber, which causes a drop to be ejected from the nozzle.
34. Continuous-Jet (CJ)
a pump directs fluid from a reservoir to one or more small nozzles, which eject a
continuous stream of drops at high frequency (in the range of roughly 50 kHz to
175 kHz) using a vibrating piezoelectric crystal.
35. Post Process These are some treatments on 3D Printed objects after completing printing
process
It will bring strength,surface finishing,density to printed objects
1
• Depowdering
• Cleaning
2
• Coating
3
• Sintering
• Infiltration
36. Depowdering & Cleaning
Remove loose powder prom the printed part
This can be performed manually by brushing or by air blowing
Chemical treatment may carried out for the removal of exes binding liquids
37. Coating
Improve the surface finish of the part by coating the part with layer of finer
particles
The coating having the range of 0.1-1 microns
Coating may or may not be with same material
38. Sintering & Infiltration
This steps increase the strength of the printed object considerably
Sintering is carries out step by step and it leads to the shrinkage of part about
1.5%-2%
Thermal treatment will reduce the amount of air and water in printed object and
hence increase strength
Infiltration increase the density of object and make it equally distributed
42. The most successful companies have adopted 3D
printing as a critical part of the iterative design
process to:
• Increase Innovation
Print prototypes in hours, obtain feedback, refine
designs and repeat the cycle until designs are
perfect.
• Improve Communication
Hold a full color, realistic 3D model in your hands to
impart infinitely more information than a computer
image.
• Create physical 3D models quickly, easily and
affordably for a wide variety of applications.
43. • Speed marketing
Compress design cycles by 3D printing multiple
prototypes on demand, right in your office.
• Reduce Development Costs
Cut traditional prototyping and tooling costs.
Identify design errors earlier.
Reduce travel to production facilities.
• Win Business
Bring realistic 3D models to prospective accounts,
sponsors and focus groups
44. • Reduce part complexity:
An immediately apparent benefit is the ability to
create complex shapes that cannot be produced by
any other means.
• Digital design and manufacturing:
All AM processes create physical parts directly from
a standardized digital file (.STL),
which is a representation of a three-dimensional
solid model.These computer-controlled processes
require a low level of operator expertise and reduce
the amount of human interaction needed to create
an object
45. • High Speed Production:
In metal casting and injection molding, a new
product requires a new mold in which to cast the
part. In machining, several tool changes are
needed to create the finished product.
However,
3D printing is a “single tool” process no matter
the desired geometry, there is no need to change
even tools.
46. Could 3D Printing Change the World?
• Adding rather than subtracting—means
everything.
• Assembly lines and supply chains can be reduced
or eliminated for many products. The final product
or large pieces of a final product like a car can be
produced by AM in one process
• Reduce environmental pollution
• It can also be considered as a kind of teleporting
49. Dummy of a Nokia mobile phone for further study
and demonstration:
• Size: 3.5 x 2 x 0.7 inches
• Printing Time: 0.5 hours
50. Education:
Helping students by bringing digital concepts into the real
world, turning their ideas into real-life 3D color models that
they can actually hold in their hands.
Printing Time: 3 hours
51. Healthcare:
• Rapidly produce 3D models to reduce operating time, enhance patient and
physician communications, and improve patient outcomes.
A 3-D Prototype of the horizontal
crossection of a human skull has been
prepared to allow its better study:
Size: 9.8 x 7.9 x 3.9 inches
(25 x 20 x 10 cm)
Printing Time: 5.5 hours
52. SUCCESSstories
Auto parts: for example, parts of "Formula 1" car engines, are
made by direct laser sintering of metal;
Aircraft parts: F-18 (fight aircraft) tube for the control
system environment;
Individual orthodontics: the company Align Technology uses
the 3D Printing to generate accurate individual dental braces for
hundreds of thousands of patients
worldwide by stereolithography from 3D-scans of the
mouth; polymer is used as a material for the production
of staples;
Individual hearing devices: manufactured by
companies Siemens and Phonak, based on 3D-scan of the ear
canal, so that the device is ideally suited to the user;
53. Conclusion
• Nothing communicates ideas faster than a three-
dimensional part or model. With a 3D printer you can bring
CAD files and design ideas to life right from your desktop
• Test form, fit and function and as many design variations as
we like with functional parts printed by 3D printer
• 3D printing has a bright future, not least in rapid
prototyping,where its impact is already highly significant
• As devices that will provide a solid bridge between
cyberspace and the physical world, and as an important
manifestation of the Second Digital Revolution
