2. 3D Printing 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.

8. Fused deposition modeling (FDM)
Fused deposition
modeling (FDM) is
an additive
manufacturing
technology
commonly used for
modeling,
prototyping, and
production
applications
10. Mechanical properties of 3D-printed samples
can be influenced by many factors
such as:
-Layer thickness
-raster angle
-build orientations
-air gap and model build temperature
11. As indicated in Table1, the tensile strengths of the polyether-ether-
ketone (PEEK) samples were significantly affected by the layer
thickness and raster angle.
