2. MEANING
• 3D printing, also known as additive
manufacturing (AM), refers to processes
used to synthesize a three-
dimensional object in which successive layers
of material are formed under computer
control to create an object. Objects can be of
almost any shape or geometry and are
produced using digital model data from a 3D
model or another electronic data source such as
an Additive Manufacturing File (AMF) file

3. METHODS
1) Stereo lithography (SLA)
–Resin based additive manufacturing.
2) Selective laser sintering (SLS)
– Powder based additive manufacturing.
3) Fused deposition modeling (FDM)
–Fusion based additive manufacturing.

4. PROCESS FLOW
• Creating models using software.
• Slicing the model using slicing
software.
• Importing it to the 3D printer
for the printed output.

5. CREATING MODELS
• This can be done by 3 methods
namely:
–3D software modeling.
–Scanning.
–Downloading from the website.

6. MATERIALS
• PLA (Polylactic acid)
• ABS ( Acryolonitrile Butadiene
Styrene)
• Nylon.
• Metal powders.
• Polypropylene resins

7. ADVANTAGES

8. Disadvantages
• Slow build rates.
• High production costs.
• Skill for designing complex shapes.
• Lower surface finish.
• Limited component size.
• Requirement of post processing.
