Printing process Printing is a process for reproducing text and images, typically with ink on paper using a print press.
Слайд 2Printing process
Printing is a process for reproducing text and images, typically
with ink on paper using a print press.
Слайд 4Invention 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THIS SUPERSEDED THE COST AND SLOW PRODUCTION.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 6Computerized 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 7Additive 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 10Different methods
Selective laser sintering (SLS)
Stereolithography
Fused deposition modeling (FDM)
Laminated object manufacturing
Слайд 11SLS 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 12STEREOLITHOGRAPHY
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 13STEREOLITHOGRAPHY
(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 14FDM
Fused deposition modeling (FDM) is an additive manufacturing technology commonly used
for modeling, prototyping, and production applications
Слайд 15Laminated 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 18What is ABSplus?
ABSplus is a production-grade thermoplastic that gives models the
ability to perform just like production parts in real-world functional testing.
Слайд 21The 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 22The 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.

The ‘Print Carriage’ then moves across this layer depositing the binder.
Слайд 23The 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 24The 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 253D 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.

Слайд 273D 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.
3D Printing can be used to create replacement parts.
Слайд 29Challenges 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 30In 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.
