"Castomize is developing a new generation of orthopedic casts in Singapore, using '4D-printing' to make limb immobilization lighter, cleaner, and easier to adjust. The company's cast system moves away from the dense, wrapped structure of fiberglass, and toward a pre-made mesh shell that softens with heat, molds directly to the patient's limb, and hardens again as it cools."
"Castomize's main product is a re-moldable orthopedic cast made from smart thermoplastic materials and a moisture-resistant inner layer. Each piece is produced in advance, then activated through heat at the clinic. Once warmed, the fibers become flexible enough for a healthcare professional to shape the cast around the patient's wrist, forearm, elbow, or ankle, depending on the model."
"This approach gives the product its '4D-printed' label. The fourth dimension is time: the printed object changes state when exposed to heat, allowing a standardized part to become customized during application. The cast is heated, placed around the limb, clipped into position, and allowed to cool into a firm support structure."
"The team describes the process as faster and cleaner than conventional casting, with no 3D scan required and no cast saw needed for removal. The most visible difference is the open lattice structure. Instead of covering the limb in continuous layers, the Castomize cast uses a perforated shell that al"
Castomize is developing orthopedic casts in Singapore using 4D-printing to make immobilization lighter, cleaner, and easier to adjust. The system replaces dense fiberglass wrapping with a pre-made mesh shell made from smart thermoplastic materials and a moisture-resistant inner layer. Cast pieces are produced in advance, then activated with heat at the clinic. After warming, the material becomes flexible so clinicians can shape it around the patient’s wrist, forearm, elbow, or ankle, then clip it into position and let it cool to harden. The open lattice design supports skin breathing and water passage, and the process aims to be faster and cleaner than conventional casting, without 3D scanning or cast saw removal.
