Creates a product by removing sections from a block of material.
Generates waste through the excess material that is removed.
Limited design capabilities.

8. 3D Printing
A method of Additive Manufacturing that adds material to an
object layer by layer to create the final product.

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

(SLS) is an additive
that uses a high power laser
(for example, a carbon
dioxide laser) to fuse small
particles of plastic, metal

21. The PRINTING CYCLEa)
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).
22. The PRINTING CYCLEb) 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.
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
The process repeats until the model is complete
24. The PRINTING CYCLEc) Depowdering/Recycling :
When finished the model, it is suspended in the powder to
At the end of curing time , the machine then automatically
removes most of the powder around the model by vaccum
The loose powder is pneumatically conveyed through the
system for reuse.
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
Once a pass is finished, the platform lowers slightly into the vat,
allowing more uncured polymers to cover the object.
