3.7 - 3D Printers Flashcards
What is a 3D printer?
A printer that prints in three dimensions, creating objects that you can hold in your hand.
What is the term used for 3D printing?
Additive manufacturing.
How does additive manufacturing work?
It creates layers upon layers to build the final 3D model.
What is the advantage of 3D printing in prototyping?
It allows for rapid creation of prototypes that can be built on screen and then printed to see in real life.
Where are 3D printers used besides Earth?
On the International Space Station to create specialized parts.
What is filament printing also known as?
Fused Deposition Modeling (FDM).
How does filament printing work?
It melts filament and places it in fine layers to create a 3D object.
Why is filament printing popular?
It has a large print bed, easy filament management, low mess, and easy disposal.
What does the filament do in filament printing?
It melts in the print head and creates the 3D object layer by layer.
What is another type of 3D printing besides filament printing?
Stereolithography printing, also known as resin printing or SLA printing.
What is the key difference between filament and resin printing?
Resin printing uses liquid resin and light to harden layers, while filament printing uses melted filament.
How does stereolithography (resin) printing work?
The build platform moves into liquid resin, where UV light or a laser hardens the resin to create each layer.
What is the biggest challenge with resin printing?
Managing the liquid resin safely and disposing of it properly as hazardous material.
What is the print bed in 3D printing?
A large flat surface used to build the 3D object, either adhesive on the bottom for filament or on the top for resin printing.
Why does the print bed need to be completely level and still?
To ensure the object being printed stays in place and doesn’t move during the printing process.
What is the print bed like for filament printing?
It’s a large surface that is sticky to keep the object from moving.
What is the print bed like for resin printing?
A small area at the bottom of the printer where the light hardens the resin.
Why is the print bed smaller in resin-based printers?
Because the print bed is the area where the light hardens the resin.
Why must resin in SLA printing be handled carefully?
It requires protective gear, and leftover resin must be taken to a hazardous materials facility.
What is the function of the print bed in filament and resin printing?
To provide a stable surface for building the 3D object, ensuring it stays in place during printing.
