The construction and assembly of the Maratus volans head.
Since the 2018 and 2019 skulls are composed from the same 3d model and resultant print, this page uses photos from both builds to show the construction process.
The “low expansion” spray foam I use cures through the evaporation of solvents. The outside of the foam blobs can be quite dry, and yet the insides still be soft and sticky. Give your skull a day or two to cure fully.
I didn’t take any pictures of the excavation, the process where I removed all the superfluous foam from the interior. It’s a messy process that involves a lot of carving with knives, with other knives, with scissors and fingers and pliers. You’ll want a vacuum cleaner handy to prevent crumbs from traveling too far.
After removing the excess foam, the skull was not as rigid as I wanted it to be. I coated the skull in several layers of papier-mâché to give it back that rigidity, and to cover over the masking tape that held the folded paper template together.
Papier-mâché is a process that takes hours over many days, as you wait for water-laden glue to dry out in front of a fan. I added one or two layers a day over the span of a week.
At this point in the process, the skull’s structure is built out. I’ll call this article finished, and direct you back to the index of the Maratus head project, where you’ll find links for how I made the eyes, furred the skull, and constructed the pedipalps.
