Purpose This paper aims to develop 3D-printed customized padding to increase pressure at the zero pressure region. This padding is specifically intended for facial areas with complex contours in pressure therapy treatment of hypertrophic scars. Design/methodology/approach To carry out this study, a full-face head garment was fabricated by a local occupational therapist, and pressure measurements were conducted to establish the pressure exerted by this head garment and to determine the zero pressure region. Furthermore, an additional manufacturing method was used to construct customized padding, and pressure measurements were performed to measure the pressure exerted after application of this customized padding. Findings The results reveal that 3D-printed customized padding can increase pressure at the zero pressure region, which occurs on complex contour surfaces with a spatial gap because of non-contact of the head garment and facial surfaces. Practical implications This paper suggests that an additive manufacturing method using 3D printing is capable of producing accurate, functional and low-cost medical parts for rehabilitation. Moreover, the 3D-printed padding fabricated by additive manufacturing assists in generating optimal pressure, which is necessary for effective pressure therapy. Originality/value Digital design using 3D scanning, computer-aided design and 3D printing is capable of designing and producing properly fitting, customized padding that functions to increase pressure from zero to an acceptable pressure range required for pressure therapy.
