An undercut is a recessed or overhanging area of a form where material is removed beneath a projecting surface, so part of the design tucks under another and cannot be seen from directly in front. In trophy and award design, undercuts create genuine three dimensional depth, dramatic shadow, and the illusion of forms that float or detach, giving sculpted awards a richness that flat carving cannot reach.
The undercut is where relief begins to behave like full sculpture. It is the technique that makes a carved figure look like it could step off its background, or a sculpted ribbon look like it truly wraps around a form. At Fabit, undercuts are an advanced tool we use to give the most ambitious awards their sense of living, three dimensional depth, and this entry explains what they are and why they demand expertise.
What an undercut is
An undercut occurs when material is cut away underneath a raised or projecting element, creating an overhang. Imagine a sculpted arm that lifts away from a body, with real space visible beneath it, or the underside of a curled leaf that you can see into. Those spaces beneath the projecting form are undercuts. They are the opposite of a simple raised bump, because they involve the removal of material from below, not just building up from above.
Undercuts are what give sculpture its convincing depth. Without them, even a deeply raised relief can look like a mound rather than a form with a genuine underside. With them, the eye reads true volume and the piece comes alive.
Why undercuts matter for awards
For a premium award meant to be admired closely, undercuts deliver a level of realism and drama that flat sculpting cannot. The deep shadows cast by an overhang create strong contrast, so the piece has visual punch even from a distance. The hidden spaces reward close inspection, so the recipient discovers new detail when they pick it up. And the sense of forms detaching from their background makes the award feel like a genuine sculpture rather than a stamped emblem.
We use undercuts selectively for signature pieces within our custom trophy service, where the added depth justifies the added design and production complexity.
The technical challenge of undercuts
Undercuts are demanding to produce, and this is where technique and technology matter enormously. Traditional casting struggles with undercuts because a rigid mould cannot release a form that hooks underneath itself without complex multi part moulds or flexible tooling. Machining struggles too, because a cutting tool cannot easily reach beneath an overhang. This is precisely why undercuts historically signalled master craftsmanship.
Modern 3D printing changes the equation dramatically. Additive manufacturing builds a form layer by layer, so it can create overhangs and hidden spaces that would be impossible to cast or machine in one piece. This is one of the reasons our 3D printed trophy approach unlocks designs that older methods could not achieve.
Undercuts and 3D printing freedom
Because we sculpt digitally and produce with modern additive methods, undercuts are part of our creative palette rather than a barrier. We can design a form that genuinely wraps, curls, and overhangs, preview it from every angle in software, and produce it faithfully. This design freedom is a core advantage of working with an in-house 3D studio, and it lets us say yes to concepts that a traditional trophy supplier would decline.
Design considerations for undercuts
- How deep an undercut can go while keeping the piece structurally sound
- Where overhangs will cast the most effective dramatic shadow
- How the hidden spaces reward close viewing and handling
- Whether the material and production method can realise the undercut cleanly
- How to protect delicate overhangs during worldwide shipping
- How undercuts combine with high relief for maximum sculptural depth
Undercuts and material selection
Not every material supports deep undercuts equally. Printed polymers and resins handle intricate overhangs beautifully. Metals achieved through certain processes can too, though the method matters. Fragile materials require thicker, more conservative undercuts to survive handling. Our materials guide helps match the ambition of the undercut to a substrate that can carry it safely.
Protecting undercuts in transit
An overhanging form is inherently more exposed than a solid one, and because Fabit ships worldwide, we design undercuts with the journey in mind. That can mean keeping the most delicate overhangs slightly more robust, orienting the piece thoughtfully in its packaging, or reinforcing the base where an undercut element attaches. The drama survives because it was engineered to.
When undercuts are worth it
Undercuts add cost and complexity, so they are not right for every award. For volume programmes with simpler emblems, they may be unnecessary. For a flagship sculpture, a lifetime achievement, or an artistically ambitious commission, they can be the defining feature. Our advisory role is helping clients judge when the sculptural payoff justifies the investment.
Frequently asked questions
Why are undercuts considered advanced?
Because they require removing material beneath a projecting form, which traditional casting and machining struggle to do. 3D printing makes them far more achievable.
Will an undercut make my award fragile?
Not if designed properly. We engineer overhangs for strength and protect them for worldwide shipping.
Can undercuts be produced in an edition?
Yes. Because they live in the digital model and are 3D printed, we reproduce undercuts consistently across a series.
How do I explore undercut designs?
Share your concept and our Antwerp studio responds within 24 hours to assess and develop it.
