3D Basics
What Is 3D Printing?
3D printers are machines that meltdown different materials and reshapes them into new objects
What is the internal structure of a print called?
infill
What is fillament?
material printers used
How do you get a model from your computer into the slicer?
Drag and drop from the file explorer on computer
What is the file type for 3D models?
.stl
How Does a 3D Printer Work?
Plastic material called filament gets melted down and pushed out of a nozzle. The machine Traces 2D faces of the 3D model
Why do we need support?
Overhangs
What is the hot end?
Part that heats up with nozzle where filament comes out
WHat happens if the slicer is not configured for the correct model of printer?
The print will not work
What are some 3D modeling softwares we have used in class?
TinkerCAD, Onshape
What Is a “Dimension”?
In this context “dimension” refers to number of directions of movement
How do 3D printers create 3D shapes?
printing 2D faces layer by layer
What is the build plate?
Flat plate that first layer of print adheres to
How can we make a print stronger in the slicer?
increase infill
What is one TinkerCAD Modeling Technique you remember?
(many answers)
How do you go from 2D to 3D?
Add a direction of movement
How do layer lines effect the structure of a print?
Prints are weaker in the direction of layer lines
What are the 3 axis’s on a printer?
X, Y, Z
What does the slicer show you in the preview page?
total print layer by layer including brim and support
What is the difference between modeling software and slicing software?
Modeling software is used to make 3D models, slicing software is used to prep the model to print
What is the face shape of the following 3D objects?Cube, Cylinder, Shpere
square, circle, circle
Show the direction of movement for the three axis’s on the 3D printer
(demonstrate on physical printer)
What type of file does the slicer genrate?
gcode. code that the printer can read
What is a sketch?
2D trace of a face shape used to create a 3D shape
