Printing process
Printing is a process for reproducing text and images, typically

with ink on paper using a print press.

Слайд 3

GUTTENBERG’S PRINTING PRESS.
INVENTED IN 15TH CENTURY
USED MOULDS MADE OF BRASS

Слайд 4

Invention of first printing machine
FIRST PRINTING MACHINE WAS INVENTED BY JOHANNES

GENSFLEISH IN 1803.
THIS SUPERSEDED THE COST AND SLOW PRODUCTION.

Слайд 5

Subtractive Manufacturing
Creates a product by removing sections from a

block of material.
Generates waste through the excess material that is removed.
Limited design capabilities.

Слайд 6

Computerized Numerical Control (CNC) Machining
A method of Subtractive Manufacturing that removes

sections from a block of material by cutting or drilling the excess material away.

Слайд 7

Additive Manufacturing
Creates a product through adding materials to the object.
Adds material

layer by layer until printing is finished.
Allows for complex and intricate designs.

Слайд 8

3D Printing
A method of Additive Manufacturing that adds material

to an object layer by layer to create the final product.

Слайд 9

3D printing
Imagine a near future in which a device connected

to your desktop prints a SOLID OBJECT!!!!!!
We can have tangible goods and intangible services delivered over the INTERNET.

Слайд 10

Different methods
Selective laser sintering (SLS)
Stereolithography
Fused deposition modeling (FDM)
Laminated object manufacturing

Слайд 11

SLS method
Selective laser sintering (SLS) is an additive manufacturing technique that

uses a high power laser (for example, a carbon dioxide 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

Слайд 12

STEREOLITHOGRAPHY
Stereolithography is an additive manufacturing process using a vat of liquid

UV-curable photopolymer ”resin” and a UV laser to build parts a layer at a time.

Слайд 13

STEREOLITHOGRAPHY (contd).
CAD (Computer Assisted Design) Programs help users create STL Files

for the 3D Printers to read.
STL (STereoLithography) file format – a file format which uses many little triangles to make a 3 dimensional plot of the objects intended surface.

Слайд 14

FDM
Fused deposition modeling (FDM) is an additive manufacturing technology commonly used

for modeling, prototyping, and production applications

Слайд 15

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.

Слайд 18

What is ABSplus?
ABSplus is a production-grade thermoplastic that gives models the

ability to perform just like production parts in real-world functional testing.

Technique

Слайд 20

Слайд 21

The PRINTING CYCLE
Preparation :
Once you click “3D print “ from

Z-print , the printer initiates the pre build routine.
First it warms the air inside the printer and creates optimum operating environment.
At the same time , it fills the ‘Build Chamber’ with 1/8th inch layer powder ( so that finished parts rest on it).

Слайд 22

The PRINTING CYCLE
b) Printing :
Once the pre-build is complete ,

the printer begins printing the layers created in the Z-print software.
The machine deposits 0.1mm thick layer of powder from the ‘Hopper”.
The ‘Print Carriage’ then moves across this layer depositing the binder.

Слайд 23

The PRINTING CYCLE
The binder solidifies the powder in that cross section

of the model.
The piston below the ’Build Carriage ’ lowers the powdered bed by 0.1mm , preparing the next layer.
The process repeats until the model is complete

Слайд 24

The PRINTING CYCLE
c) Depowdering/Recycling :
When finished the model, it is

suspended in the powder to cure.
At the end of curing time , the machine then automatically removes most of the powder around the model by vaccum pressure.
The loose powder is pneumatically conveyed through the system for reuse.

Слайд 25

3D Printing : The Chemical Process
A platform which serves as the

base of the object is submerged into a vat of polymers.
UV light cures and hardens these polymers with each pass over the object.
Once a pass is finished, the platform lowers slightly into the vat, allowing more uncured polymers to cover the object.

Applications of 3D Printing

Research

Слайд 27

3D Printing and Sustainability
3D printing with non harmful chemicals.
3D printing generates

almost no waste during manufacturing, and does not require lubricants.
3D Printing can be used to create replacement parts.

Слайд 28

SUCCESS stories
3D printed Jaw

Слайд 29

Challenges Facing 3D Printing
Intellectual property rights of the 3D Printer users.
Nearly

anything can be printed by 3D Printers and this is a troubling prospect if criminals use 3D Printers to create illegal products.

Слайд 30

In Conclusion
3D printing is an expanding technology which may soon start

an industry in which everyone has the possibility of being a manufacturer.
3D printing has a lot of possible benefits to society, although the products created must be regulated.
