Additive Manufacturing
This machine builds objects one layer at a time.
What is a 3D printer?
What material is packed around the pattern?
What is sand?
This process removes material to make a part.
What is machining?
Before pouring, metal must be this.
What is melted?
You wear these to protect your eyes.
What are safety glasses?
Name the plastic used in many classroom 3D printers?
What is filament?
Why do we pack the sand tightly?
To keep the mold's shape.
True or False: Machining adds material.
What is False?
What do you pour molten metal into?
What is a mold?
Should you wear sandals in the lab?
What is No?
Does a 3D printer build from the top down or bottom up?
What is bottom up?
Why do we let the metal cool before opening the mold?
So the metal becomes solid and is safe to handle.
Name one thing that can be machined.
Wood, plastic, or metal.
What happens to solid metal after it cools?
It shrinks
Before touching a machine, who should you ask?
The instructor.
What did we build with our 3D printer kits?
What is a dinosaur?
Why do we split the mold into two halves?
So we can remove the pattern.
Name one machine used for machining.
Drill press, lathe, or milling machine
Name one thing that can be made by casting.
Wrench, toy car, bell, engine part, etc.
True or False: Running in the lab is safe.
False
Which process usually creates less waste: machining or 3D printing?
What is 3D printing?
What tool do we cut into the mold so metal can be poured?
What is a sprue?
What material did we machine during camp?
Clay
What are the two ways we shaped metal this week?
What are casting and forging?
Name one piece of PPE besides safety glasses.
Gloves, hearing protection, or closed-toe shoes.
