Alignment of the prosthesis with the stump is performed through the socket. Good socket stump fit provides near-normal posture and weight-transfer pattern. It also ensures that the walk is painless and low-energy. Recently, studies have been carried out to use 3D printers in socket production. 3D method is accepted as an effective and reliable method in prosthetic socket production. The purpose of this study is to compare the pressures distrubution in the sockets produced by conventional and 3D scanners and printers in the transtibial amputee.

Inclusion Criteria:

Exclusion Criteria:

• To have orthopedic, neurological, etc. disorder other than amputation that will affect posture or gait
• The presence of pain that will affect the posture or walking pattern
• Wound / tenderness on the stump
• Visual impairment that will affect the posture or gait pattern
• Use of any assistive device (walking stick, canary, etc.) during walking
