ORIGAMI / INDUSTRIAL ORIGAMI
Industrial origami, explained.
Industrial origami applies the logic of paper folding to sheet metal: one flat sheet, a deliberate pattern of creases and curves, and a finished load-bearing structure — no stamping dies, no welded assemblies.
STILFOLD is the Swedish company behind the method. It built the software and folding hardware to turn origami principles into a manufacturing technology, and proved it by folding the chassis of the STILRIDE 1 electric motorcycle from a single sheet of stainless steel.
01 / THE CRAFT
Strength from geometry, not mass.
Most of a product's environmental impact is locked in at the design stage. Folding attacks it at the source: less material, fewer parts, less process energy — the three levers that dominate a product's footprint.
Fold, don't fabricate
A crease turns a flat sheet into a three-dimensional structure. The geometry itself does the work that extra brackets, gussets and welds normally do.Stiffness from the curve
A folded or curved panel is dramatically stiffer than a flat one of the same weight. Strength comes from shape, not added material.One material
A mono-material structure needs no dissimilar-metal joints, so it is simpler to separate and recycle — and it behaves predictably in a crash.Software-led folding
STILFOLD's proprietary tools unfold a product back to a single flat sheet, then compute the creases and curves that rebuild it in metal.
02 / THE MAKER
STILFOLD, the studio that folds steel.
STILFOLD is a Stockholm-based design and technology company. Its proprietary software takes a designed part, unfolds it back to a flat sheet, and computes the folding sequence that rebuilds it — while its folding hardware executes the creases in stainless steel.
The method was developed and proven on STILRIDE 1, the electric motorcycle this site documents. What began as a way to build one machine cleanly has become a manufacturing approach for anything made from sheet metal: lighter parts, simpler tooling, and production that can move closer to where products are sold.
03 / IN PRACTICE
One sheet. A few dozen parts. A fraction of the footprint.
A conventional motorcycle chassis is built from roughly 150 stamped and welded parts weighing about 45 kg. The STILRIDE 1 chassis is folded from stainless steel into a structure of around 20 parts at 15 kg — a third of the mass, with no welds in the primary structure.
Because the chassis is one material, it is also simpler to recycle, and its folded geometry delivers stiffness without extra reinforcement.
04 / MEASURED, NOT CLAIMED
What a life-cycle assessment shows.
An independent screening LCA by IVL Swedish Environmental Research Institute (November 2021) compared the STILRIDE 1 with a reference scooter over 58,000 km and ten years of use.
Total climate impact came to 885 kg CO₂-eq for the STILRIDE 1 against 1,030 kg for the reference. On a clean electricity grid the gap widens sharply: the reference scooter carries up to 80% more CO₂ in total, because production-phase savings matter more when charging is clean.
+80%
more CO₂ for a conventionally built reference scooter on a clean grid — the strongest evidence that how you manufacture matters as much as what you ride.
