True
False
What type of filament do the 3D printers in STEM Lab use?
ABS (petroleum-based)

TinkerCAD
PLA (plant-based)
What is a best benefit for using PLA over ABS?
It comes in different colors.
It saves you $2 per spool.
It uses renewable resources.
Which part of the printer allows the filament to exit (leave) the machine?

feet
inches
millimeters
How many millimeters are in 30 centimeters?
_____mm = 30 cm
3 mm
300 mm
30 mm
3,000 mm
Describe the changes in the state of matter from the:
filament --> extruder --> 3D printed object
solid --> gas --> solid
liquid --> solid --> liquid
solid --> liquid --> solid
All of these are reasons 3D printers weren't being used a lot before 2000, except:
3D printers were too big.
3D printers were too expensive.
3D printers weren't invented yet.
What is a 3D printer best used for?
Printing unique, specific and custom projects.
Printing mass production, common objects.
