English Abstract

The aim of the research is to use the technology of three-dimensional printing in the manufacture of a orthotic to treat bone fractures from lightweight thermoplastics instead of using the traditional methods that are made of gypsum material, the practical aspect included taking the measurements of the donor's hand and design of the three-dimensional orthotic- socket in the software (solid work2019), and after that the file was converted to a format (stl) and The g-code file was inserted into the printer software for dividing the 3-D design into slices, and the file into the printer was inserted via (SD card) or via linking the printer with the computer straightforward, The printer was run, and the file to be printed was selected from the screen set on the printer.

The heating process of the nozzle and the bed starts and relies upon the kind of material to be printed, for instant in a material (PLA); the extruder temperature is (210°C), and the platform temperature is (70°C).

, an (f-socket) test was performed on it, and the stresses incurred by the predicate were obtained, and the results were acceptable according to standard and laboratory values(110, 150, 210, 140) KPA, we notice the difference between the value of the yielding stress and the ultimate stress of the PLA material ( 41, 34.4) MPA, and this indicates that the PLA is from the ductile materials and is not considered a brittle material.
