OLT Footcare has introduced a 3D foot scanner + 3D printer package for manufacturing custom foot orthotics by 3D printing. With a OLT system, a medical practitioner can scan a patient’s feet, fill out a prescription form on a computer screen, verify digital orthotic models with the foot data on a computer, and 3D print the custom foot orthotics. 3D printing can be done in his/her clinic or a central 3D printing lab. The orthotics shell length/width, arch shape, shell rigidity, heel cup depth and rear foot posting options are available on the prescription form. This entirely new process of prescribing/manufacturing of custom foot orthotics has transformed the 50+ years conventional manufacturing process into a digital one. Now, a medical practitioner is in fully control of the entire process of creating 3D printed custom foot orthotics. In addition, every manufacturing step is digitally controlled. It will be much easy to accurately make multiple pairs of custom foot orthotics with different prescription for incremental adjustment of a patient's condition.
