Infill is the internal structure printed inside the walls of a 3D printed object, a repeating pattern of material and empty space that determines how heavy, how strong and how economical a part will be without needing to make it completely solid. It is one of the most powerful levers we control during production, because it lets us tune the physical character of a trophy from the inside out, invisibly, long before anyone sees the finished surface.
What infill is and why it exists
If every printed object were completely solid, it would consume enormous amounts of material, take far longer to print and often weigh more than is desirable. Infill solves this by filling the interior with a lattice rather than a solid mass. The outer walls define the shape and surface, while the infill inside provides internal support and strength. By adjusting the pattern and density of that lattice, we can dial a part anywhere from nearly hollow and feather light to almost solid and substantial.
This interior is entirely hidden in the finished piece, yet it governs how the object feels in the hand and how it behaves under stress. Infill is a quiet, structural decision that never shows itself directly but is felt in every moment the trophy is handled.
How infill shapes a trophy
The perceived quality of an award owes a great deal to its weight and solidity. A piece that feels too light can read as insubstantial, while excessive weight can make a large trophy unwieldy and costly to ship. Infill is how we strike the right balance. For a large sculptural form we might use a lower infill to keep it light enough to handle and post worldwide, then rely on strong walls for rigidity. For a smaller piece meant to feel dense and premium, we might raise the infill considerably.
Strength is the other half of the equation. Infill carries loads through the interior of a part, resisting bending and impact. Where a design has a slender neck or a projecting feature, thoughtful infill in that region adds resilience precisely where it is needed. This is engineering in service of emotion, ensuring the piece survives handling, display and travel while feeling exactly as it should.
Common infill patterns
The geometry of the internal lattice affects both strength and print efficiency.
- Grid: a simple, reliable crosshatch suitable for many general pieces.
- Gyroid: a flowing three dimensional pattern offering even strength in all directions.
- Honeycomb: a strong, efficient structure inspired by nature.
- Triangular: excellent rigidity for parts that resist bending forces.
- Concentric: follows the part outline, useful for flexible or specialised needs.
Infill density and the trade offs
Density is expressed as the proportion of the interior that is filled. Low density prints faster, weighs less and uses little material, but offers less strength. High density is stronger and heavier but slower and more material intensive. There is no single correct value; the right density depends entirely on the size, purpose and desired feel of the piece. Part of our advisory role is to select this deliberately for each project rather than defaulting to a generic setting. How infill interacts with the chosen substrate is explored further on our materials overview.
Infill and other processes
Infill is primarily an FDM concept, since FDM builds up material along paths that can leave planned internal voids. Resin processes such as DLP behave differently and are often designed hollow with drainage in mind rather than using a lattice. When a piece is destined for casting, the printed pattern feeds a mould and the final solidity comes from the cast material instead. Knowing which strength strategy each process calls for is central to how we plan a build, as reflected across our custom trophies service.
What this means for your award
You will never see the infill of your trophy, but you will feel its influence every time you lift the piece. Our team engineers this hidden interior so that the finished object feels substantial, survives its journey and honours the achievement it represents. Share your concept through our design studio and we will advise on the internal strategy alongside the visible design.
Infill, weight and worldwide delivery
Infill takes on particular importance because so many of our awards travel. A piece may be presented in Antwerp one week and posted to a recipient on another continent the next. A trophy that is needlessly solid is heavier and more expensive to ship, and its very weight can raise the risk of damage in transit if the internal structure is not distributing stress well. By tuning infill thoughtfully, we make pieces that feel gratifyingly substantial in the hand yet remain practical to package and post safely around the world.
Because this engineering is done in house, we can weigh these trade offs against the specific journey a piece will take. We know how our own materials behave, how our finishing adds or subtracts weight, and how a given form should be filled to survive handling and travel. That end to end control, from the internal lattice to the shipping carton, is part of why clients trust us with awards destined for ceremonies far beyond Belgium, and why we can commit to a 24 hour response on every enquiry that begins that journey.
Frequently asked questions
Does higher infill always mean a better trophy? No. The right infill depends on size, purpose and desired weight. More is not automatically better; appropriate is better.
Will infill affect the weight of my award? Yes, significantly. Infill is our primary tool for tuning weight, which we balance against strength and shipping practicality.
Can I feel the infill from outside? No. Infill is fully enclosed by the outer walls, so it is invisible and untouchable, felt only through the overall weight and solidity.
Does infill matter for shipping worldwide? Very much. Sensible infill keeps large pieces light enough to ship efficiently while remaining strong enough to arrive perfectly, which is why we engineer it deliberately for every award before it leaves our workshop in Antwerp.
