How it works
An engineer wants to know how things work.

Drawing with a 3d pen is not easy, and it will take practice. Whenever you are trying to learn, please be patient with it and with yourselves.
WARNING
Never touch the nozzle or the plastic near the nozzle. It is hot and could hurt you.
This is a Polaroid Play 3d pen.
- Plastic goes in the top and extrudes or comes out of the nozzle when it melts.
- It takes a few seconds to solidify, but then it is strong.
- It is magical engineering!
Some essential techniques:
- Closeness
- Speed
- Anchoring
- Direction/Rotating
The core principle: you’re after big thick blobby lines.
Let’s get started
The gears that push the plastic through the pen use a motor that needs electricity to turn. So, now is the time to plug it in to your computer, via the usb cord. Everybody got theirs plugged in?
You should see a red light, which means it’s heating up.
Make sure you’ve got a sharp end of your filament, make sure it’s not been previously melted. If it has a melted end, get a grown up to cut the end with a pair of scissors.
Once the light turns blue, the pen is hot enough, and we can load in the PLA filament by pressing the extrude button.

Once you’ve had some practice, try doing the first letter of your name, or even your whole name. Tip: do the outline of the letter first, then fill in using “lawnmower lines”.
