WPP: "Sam, can you design and print a 3D model of Sir Martin Sorrell?"
Sam: "When do you need it by?"
WPP: "5 days from now."
Sam: "No way! Forget it."
WPP: "…It's going to be sent into space."
Sam: "Consider it done!"
 
Sir Martin Sorrell. This version isn't 3D printed.

How to Rapidly Model and Print a 3D Head for Launch into Space

Step 1: 3D model the head using photos for reference:

I use patch grids - it's old-school, but it's fast and accurate and gets the job done.

Step 2: Add glasses, subtracting a notch from the head for them to fit as a separate part.

Step 3: Print the glasses on an FDM printer in black filament:

This provides a high level of wire detail and control over placement. Still need to 'puff them up' a bit to be printable. Thanks VisMed3D!

STEP 4: HOLLOW-OUT 3D THE MODEL.

It has to be less than 100g for this spaceflight!

Be careful! Too much hollowing makes it brittle:

Step 5: Print! The head is printed on a Zcorp ProJet Color composite printer.

Primary print done via Sculpteo in Belgium.

Contingency plan in case of a customs delay: a backup is printed on the only Zcorp Color Sandstone Printer in Athens.

mmmm....Chocolate.
mmmm....Chocolate.

Step 6: Cast a silicon mold from the 3D print - and fill it with melted chocolate.

It'll harden in 15 minutes in the freezer.

Not necessary for spaceflight, but certainly takes the edge off if the launch fails and the payload is destroyed.

Step 7: Launch!

Amazing work by James, Adam and company!

Make sure you choose the right glue. In these extreme conditions, most terrestrial adhesives will fail, sending a pair of 3D printed glasses plummeting toward earth.
