This document summarizes research on the mechanical behavior of 3D printed parts. It discusses how factors like layer thickness, build orientation, and temperature can influence properties of printed samples. Tensile strengths of polyether-ether-ketone (PEEK) samples were significantly affected by layer thickness and raster angle. The document also outlines applications of 3D printing like medical implants and prototypes. A variety of materials that can be 3D printed are listed, including metals, polymers, and biopolymers.

• Creates a product
through adding
materials to the
object.
• Adds material layer by
layer until printing is
finished.
• Allows for complex
and intricate designs.

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.

Through additive manufacturing dense
components with near net shape are
possible to produce so good surface
finish quality can be achieved.
