What can be physically configured concerning the extruder on a 3D printer?
Different nozzles to be attached, allowing for finer or coarser control, depending on required detail.
What is the benefit to using smaller nozzles on an extruder on a 3D printer?
It is more precise.
What is the caveat to using smaller nozzles on an extruder on a 3D printer?
It is prone to clogging.
What is the benefit to using larger nozzles on an extruder on a 3D printer?
It is less prone to clogging.
What is the caveat to using larger nozzles on an extruder on a 3D printer?
It creates bulkier builds with less detail.
Gears, Motors, and Motion Control System
Control either the movement of the build surface or the extruder itself.
Fans
Help cool the melted filament as it’s extruded to ensure that the object retains its intended shape as the layers are built.
Why is proper cooling important when 3D printing?
It avoids deformities in the final build product.
Filament
The “ink” for a 3D printer that comes on a roll or spool and is fed into the extruder to create the object layer by layer.
What makes some 3D printer filament different from other 3D printer filament?
The diameter of the filament itself, like 1.75mm or 3mm.
What type of material is 3D printer filament usually made up of?
Plastic.
What type of plastic filament do most home and office 3D printers use?
PLA or ABS.
What makes the different filament types different?
Different properties and the requirement for specific settings of the extruder temperature and build plate temperature.
What does proper settings for different filament types ensure?
Proper adhesion and build quality.
Resin
A liquid plastic material in more advanced 3D printers, stored in a reservoir tank.
What is liquid plastic resin also known as?
Photo polymer.
How it the resin in 3D printers cured?
Through the use of ultraviolet lasers.
Where is the utilization of resin in 3D printer seen more often?
In high end printers, not in home or small office environments.
