What is the main process involved in 3D printing with a typical filament printer?
Heating metal sheets to form layers
Pouring liquid resin into a mold
Extruding melted plastic layer by layer
Carving the object from a solid block
Which statement best describes the difference between 3D printing and injection molding?
3D printing involves pouring molten material into a mold, while injection molding builds objects layer by layer.
Injection molding is used for customization, while 3D printing is for mass production.
3D printing builds objects layer by layer from a digital design, while injection molding injects molten material into a mold cavity.
Injection molding is faster than 3D printing due to its digital nature.
Why are heated beds (or build plates) used in filament 3D printers?
To cool down the printed object
To prevent warping and improve adhesion
To increase the speed of printing
To decrease the cost of materials
Which of the following is NOT a common material for 3D printing?
PLA (Polylactic Acid) – [Prototyping, Educational Models, Decorative Items, Food Packaging Prototypes]
ABS (Acrylonitrile Butadiene Styrene) – [Functional Prototypes, Automotive Components, Household Appliances, LEGO Bricks]
PVC (Polyvinyl Chloride) – [Pipe Fittings, Signage, Prototyping Electrical Enclosures, Fashion Accessories]
PETG (Polyethylene Terephthalate Glycol) – [Mechanical Parts, Medical Models, Food Containers, Display Cases]
What does the abbreviation "SLA" stand for in 3D printing?
Solid Layering Apparatus
Selective Laser Apparatus
Stereolithography
Solid Laser Assembly
How are files created to instruct a 3D printer?
Using 2D drawing software
By directly programming the printer
Using 3D modeling software
By manually inputting commands into the printer
What is the function of a slicer in 3D printing?
To cut the object after printing
To convert a 3D model into printable instructions
To adjust the temperature of the printer
To add support structures to the object
Which projects are better suited for resin printers compared to FDM printers?
Large-scale sculptures
Functional prototypes
Miniatures and jewelry
Architectural models
What does the term "Infill" refer to in 3D printing?
The outer surface of a printed object
The thickness of each printed layer
The internal structure of a printed object
The base layer of a printed object
Is PLA filament considered a sustainable material?
No, it is derived from non-renewable resources
Yes, it is biodegradable and made from renewable resources
No, it is toxic and harmful to the environment
Yes, it is made from recycled plastic bottles
What is the purpose of a "raft" in 3D printing?
To provide stability for overhangs during printing
To form the outer surface of the printed object
To adjust the thickness of each printed layer
To provide a stable foundation for printing
What does the term "shell" refer to in 3D printing?
The internal structure of the printed object
The outer surface of the printed object
The base layer printed underneath the object
The supports printed alongside the main object
What is the purpose of a "brim" in 3D printing?
To provide stability for overhangs during printing
To form the outer surface of the printed object
To adjust the thickness of each printed layer
To improve adhesion to the build plate and prevent warping
What does "Layer Height" refer to in 3D printing?
The internal structure of the printed object
The outer surface of the printed object
The thickness of each individual layer of material deposited during printing
The supports printed alongside the main object
When are supports used in 3D printing?
To increase printing speed
To improve surface finish
To prevent overhangs from collapsing
To reduce material usage
What does the abbreviation "DLP" stand for in 3D printing?
Digital Layer Processing
Direct Laser Printing
Digital Light Processing
Direct Layer Projection
How does FDM 3D printing technology work?
By curing liquid resin with UV light
By selectively sintering powdered material with a laser
By extruding thermoplastic filament through a heated nozzle
By projecting layers of liquid resin with a digital light projector
What does "SLS" stand for in 3D printing?
Selective Layer Sintering
