List five ways that 3D printing could be useful in your everyday life.

2

List five safety rules for 3D printing.

3

Name three types of 3D printers and what they may be best suited for.

4

On a typical extruder type 3D printer, find and explain what function each of the following parts has:

4a

Filament

4b

Filament guide

4c

Filament stand

4d

Extruder “hot end”

4e

Base plate “print bed”

4f

Step motors

4g

Frame

4h

Control module

4i

Idler gear

4j

Hobbes gear

4k

Heat sinks

4l

Cooling fans

4m

Threaded rod “lead screws”

4n

Power supply

5

Name 10 types of filaments or infused filaments on the market today and what they might best be used for.

6

Name and try out three or more free 3D design programs and list your pros and cons for each.

7

Use a slicer program such as Cura to convert a design into layers for printing.

7a

Note the print time, before and after, as you adjust the following parameters. What effect does it have?

• Model size
• Layer thickness “quality”
• Infill density
• Wall thickness

7b

Explore other variables and settings.

8

What happens if you overheat your filaments while printing?

9

What happens if you under heat your filaments while printing?

10

Why would you or would you not want to use a heated bed when printing?

11

List five reasons you may not want to use a 3D printer to create items.

12

Read Genesis 1 and 2. In a group, discuss some of the issues God may have considered while planning and creating our earth. Think about the incredible amount of planning it takes for us to print plastic parts and how much more effort our loving Father must have put into designing us.

13

Print the following two projects using a 3D printer, one of which must be of your own design:

13a

Any design of your choice.

13b

Any item or set of items from the Bible that has a special connection to you.

14

Print, don’t buy, the 3D Printing Honor from the approved STL file, downloadable at:

3D Printing File

Use both red filament for the backing and white (glow in the dark white if you can get it) for the foreground. Note: A single extruder printer can be set to pause at any level to allow a filament swap.
