Lesson 5: Additive vs Subtractive Sculpting

Sculpting can be approached in two main ways: additive and subtractive. Understanding both will help you choose the right technique for your medium and style.

Additive Sculpting

• Build form by adding material gradually
• Layer clay to achieve volume and detail
• Ideal for clay, wax, and soft materials
• Allows flexibility to adjust shapes as you go

Subtractive Sculpting

• Remove material to reveal the form
• Common in stone, wood, and foam
• Requires precision and careful planning
• Great for defining sharp lines and contours

Choosing a Method

Match your technique to the material and desired outcome. Many professional sculptures combine both additive and subtractive methods — start additive to build volume, then refine subtractively.
