Terminology
When printing, a 3D printer uses this as material for the print
Filament
CAD stands for this
Computer Aided Design
this is the most common filament
PLA
what is the internal density of a part called
infill
A 3D printer will use this to deposit the print material onto the print bed
Nozzle/Extruder
When a print fails and produces stringy strands, this is called this
Spaghetti failure
This material is one of the most resistant to heat
ABS
what does increasing the infill density do
increases both strength and print time
This is the most common 3d printing technology
FDM Printing
In 1966, CAD was invented by these people
The french
this material has the strongest tensile strength of the major three
PLA
thickening the layer height can decrease the print time at what compromise?
quality, detail
This dictates how much of the inside of the print will be filled in
Infill
The difference between a GCODE file and an STL file is this
An STL file is a 3d model which cant be read by a 3D printer, and a GCODE file is a file that contains instructions for the 3D printer
This material has the highest print temperature of the three
PETG
what step of the process do you edit print settings
in the slicer / slicing software
Slicing software converts your 3d model into this file
SLS printers use this method to create prints
Laser melting powdered material
This material can be quite tricky to print with and an enclosed printer is strongly recommended
ABS
what is the disadvantage of speeding up prints
increased chance of errors, failure, or loss of detail
