Wheelchair racing gloves are typically solid 3D structures held in a clenched fist which help to propel the chair by pushing the glove against a rotating rail which is attached to the wheel to drive the wheelchair forward. There has been a recent movement towards developing customisable gloves using 3D scanning technique, however, currently there are no commercial offerings which allow for product customisation without being prohibitively expensive. The aim of this project, therefore, was to develop a scalable method for producing customised wheelchair racing gloves in a cost-effective way. The generated 3D forms were 3D printed in a variety of infill densities and finished with a grip liner. These 3D printed gloves were compared in terms of fit and perception of performance, and for their mass, cost and energy/power cost. The 3D printed gloves provided a substantially reduced mass with only a minimal reduction in overall strength at a comparable cost to the solid equivalent.

Creating 3D models automatically from photographs is a relatively new technology. This sort of 3D scanning is based on the principles of photogrammetry, similar in methodology to panoramic photography; the photos are taken of one object and from different positions of camera in order to replicate the object. Paper approaches different typical anatomic surfaces by photogrammetric scanning and 3D reconstruction. Documented surfaces include anatomic surfaces like foot, upper body, head, and ear. The aim is to give users recommendations, which body part is suited best for this type of scanning, or even if a combination of photogrammetry and another 3D scanning technique is advisable. Comments like possible medical applications, quality of the results, required equipment and occurring problems are to be considered.

The measurement method and analysis experiences of 3D scanning instrument used in manufacturing industry is a novel for recent company before we are going to apply the 4.0 industrial era. The research purpose is to provide a measurement and analysis results of quality control and product improvement stage in the third industrial era. This paper presents an approach for accuracy measurement of complete scanning complex geometric of marine propeller blades. The geometric accuracy of marine propeller models, which has been finished by machining processes are measured using 3D photo-scanning technique. The effects of cutting parameters, that is step-overs and feed-rates, on the geometric accuracy are investigated. Inspection of geometric accuracy is performed by comparing the result of 3D scanning measurement of finished propeller with CAD design data. The results showed that greater step-over value, the deviation value tends to be smaller. Similar to the feed-rates, greater value of the feed-rates, the deviation value tends to be smaller
