3d Printing Flashcards
What is 3D printing?
3D printing is a manufacturing process that creates three-dimensional objects layer by layer from a digital file.
True or False: 3D printing is also known as additive manufacturing.
True
Fill in the blank: The process of creating a 3D printed object begins with a __________.
digital model
What file format is commonly used for 3D printing?
STL (Stereolithography)
Which of the following is a common material used in 3D printing: a) Wood b) Plastic c) Metal?
b) Plastic
What is the role of a slicer in 3D printing?
A slicer converts a 3D model into instructions (G-code) that a 3D printer can understand.
True or False: 3D printing can only be done with thermoplastics.
False
What does FDM stand for in 3D printing technology?
Fused Deposition Modeling
What is one advantage of 3D printing over traditional manufacturing?
It allows for complex geometries and customization without the need for expensive molds.
Fill in the blank: __________ is a technique that uses lasers to fuse powdered materials in 3D printing.
Selective Laser Sintering (SLS)
What is the purpose of support structures in 3D printing?
Support structures help stabilize overhangs and complex designs during the printing process.
Which 3D printing technology is known for its speed and is often used for rapid prototyping?
SLA (Stereolithography Apparatus)
True or False: 3D printing can only be used for prototyping and not for final products.
False
What is a common post-processing technique for 3D printed parts?
Sanding or smoothing
Fill in the blank: In 3D printing, the term __________ refers to the thickness of each layer deposited.
layer height
What does the term ‘infill’ refer to in 3D printing?
Infill refers to the internal structure of a 3D printed object that provides strength and support.
Which of the following is NOT a type of 3D printing technology: a) FDM b) SLS c) CMC?
c) CMC
What is the main purpose of a 3D printer’s extruder?
The extruder melts and deposits the printing material layer by layer.
True or False: 3D printing can be used to create food items.
True
What is the significance of ‘print speed’ in 3D printing?
Print speed affects the time it takes to complete a print and can influence the quality of the final product.
Fill in the blank: __________ is a 3D printing method that uses a binder to hold together layers of powder.
Binder Jetting
What is a common application of 3D printing in the medical field?
Creating custom prosthetics and implants.
Which type of 3D printing is best suited for producing detailed and high-resolution models?
SLA (Stereolithography Apparatus)
What is the primary benefit of using biodegradable materials in 3D printing?
They are environmentally friendly and can reduce waste.
