| additive manufacturing | process of making three dimensional solid objects from a digital file |
| CAD (Computer Aided Design) | "slices" the final model into hundreds or thousands of horizontal layers |
| Material Jetting | material is applied in droplets through a small diameter nozzle; applied layer by layer making a 3D object and then hardened by UV light |
| Material Extrusion | a plastic filament is unwound into an extrusion nozzle; nozzle is headed to melt the material; object is produces by extruding melted material to form layers |
| Where is PLA derived from? | renewable resources |
| Rapid Prototyping | nventors are able to create parts of their product; through the process of trial and error they find out what works and what doesn't; they can edit the part design that they have on file and re-print it immediately; |
| extruder | deposits the filament onto the build plate |
| filament | the material used to make a 3D object |
| build plate | the platform used to make a 3D object |
| carriage | holds the extruder |
| 2 common types of filament | PLA ans ABS |
| PLA filament | Easy to print and no heated bed needed. Used on COnsumer products |
| ABS filament | durable, impact resistant. Used for parts. |
