Essential tools for sculpting in HDU

Watch this video of the process of sculpting a figure out of HDU foam and the variety of tools used to make it.

First we took this indian figure and used Photoshop to create this black silhouette.

Then we took the silhouette into the CNC software and layed it out to cut out multiple profiles out of 2″ thick, 15lb. HDU foam. HDU can be purchased from local sign suppliers.  SignFoam 4 and Precision Board are the most popular brands.

Next, we used expanding polyurethane Gorilla Glue to laminate together the profiles to create figure blocks suitable for carving. The urethane glue bonds well with the urethane foam.

Next, a battery powered chainsaw is used to round out the form getting rid of the blockiness.

Stihl makes a great battery saw I highly recommend. The MSA 200 C.

Next, the dremels were used with 4 special bits – 3 burrs and 1 sander.

After using the Dremel bits to detail the HDU, two sanders were used to smooth it out.  A flap wheel that goes on the dremel as well as this foam hand sander with replaceable 80 grit velcro strips.

When using HDU, because it is a synthetic foam, you do not want to breath this in. I highly recommend the use of goggles and a mask. The dust can be gritty and if in the eyes, it is not comfortable and could scratch your eye.
