Question 1

What are the 3D Printers mechanical components

Answer 1

Print Bed - heated or non heated
Bed Leveling 
Filaments
Plastic Extruder / Nozzle 
Thermal Sensors
Laser Curing
Cooling Fan
Motion control motors

Question 2

What are the 3D Printers Electronic components

Answer 2

Power Supply
Controller board
stepper drivers
user interface
sd card slot

Question 3

list components of a laser printer

Answer 3

imaging drum, primary charge wire (corona wire)
these are involved with putting the image to paper
wire applies a charge to the drum and the laser exposes it to light and it removes the charge which creates the image on the paper.

, fuser assembly - fuses the toner onto the paper

, transfer belt - used on a colour printer
, transfer roller - black and white printer

pickup rollers - feed the paper,
separate pads- only 1 sheet of paper is put through the printer at one time
duplexing assembly-allows multipage printing
