3D Pen- How to Make a Pac-Man Ghost

Here I show how to make a dual sided Pac-Man Ghost with a 3D Pen!

4-5 hour project

You will need:

• 3D Pen
• Red, white and blue filament
• 2 part epoxy
• Some way of heating parts of the model (lighter, cooking torch, etc.)
• Paper and pencil
• Coarse grit sandpaper

Helpful tools:

• Flush cutters
• Tweezers
• Wax paper
• Tape

Please note that I made a time-lapse video of the full process, so you can see all the little details on how to make this in the following video:

Affiliate links to the exact products I used to make this are in the video description.

A high level overview of how to make this is:

• The red and blue halves of the ghost are made separately.
• The eyes and frown are also made separately.
• The red and blue halves are epoxied together.
• The eyes and frown are heated and then applied to the appropriate side.

Printing out the steps below and following along with the video will help a lot.

** Finally take care and the proper precautions when using an dangerous equipment that this Instructable requires. **

Find an image of a Pac-Man Ghost which you like and want to base your model on. The image I used is here:

http://www.abystyle.com/en/mousepads/2164-pac-man-mousepad-ghost.html

Now copy this image into a Word or Powerpoint document. Make sure the image aspect ratio is locked and then adjust the image size to what you want your model to be.

Print this image out.

• Use the printed out image to trace over with a 3D pen, to create the front profile of the Ghost. In the video I found it helpful to trace over wax paper, so the filament did not stick to the paper.

• Then stand up the front profile and sketch half the bottom profile with a pencil. Trace this using the 3D pen.

• “Weld” (attach) the front profile to the bottom profile using the 3D pen, to create a sub-assembly.

• Use the sub-assembly to sketch the front wavy skirt of the Ghost with a pencil.

• Draw the wavy skirt with the pen and then weld it to the sub-assembly. Heating the skirt can help it conform to the round bottom profile.

• Use the sub-assembly to sketch the side rib (thick, structural bar) with a pencil.

• Use the sub-assembly to sketch the 3x front profile ribs with a pencil.

• Draw the ribs with the pen and then weld them to the sub-assembly (see video).

• Now we need to make the outer covering of the ghost:

• Use 3 layers, applied on top of each other- a course, medium, and fine layer. Allow sufficient cooling in between each layer.

• Watching the video here can help you figure out how each of these layers is applied (density needed, technique, etc.).

• Reuse the printed ghost image to draw the red ghost’s eyes and iris with the 3D pen, each with the appropriate color.

• Sketch the front profile of the ghost and then draw in the vulnerable ghost eyes and frown with a pencil. You can use Google Image search for “pac-man vulnerable ghost” to see what it looks like.

• Draw the vulnerable ghost’s eyes and frown with the 3D pen.

• Optional helpful step: use flush cutters to remove any large blobs or protrusions from the back (flat) sides of the ghost halves.

• Use the coarse grit sandpaper to sand down the back of each ghost halve. Do this until you are happy with the way they fit together.

• Apply epoxy or other bonding agent to each halve and then bond them together.

• I use 5 minute setting epoxy so I can slide them around until I am happy with their placement.

• Don’t apply the epoxy right to the edge or it will squirt out the center seam and look undesirable.

• Use heat source to attach red ghost irises to “eyeballs”.

• Use heat to bond eyes to red ghost body.

• Use heat to bond vulnerable ghost eyes and frown to blue ghost body.

Congratulations, you now have a dual sided Pac-Man Ghost, made with a 3D Pen!
