Reducing Cost of Walking w ith Fused Deposition Modelling Rendering Point Cloud Data

Abstract

In the present work, FDM technique has been used over the traditional plaster moulding technique. ABS polymer was used in the fabrication of the AFO. The main focus has been done on finding an easy method to fabricate AFO. A healthy subject of 24 years of age was taken and his lower limb was scanned. Custom AFO 's are traditionally manufactured using plaster moulding that requires multiple patient visits and extensive labour and production time. Fused deposition modelling (FDM) technique has been used in the present work to produce the AFO, which helps with custom fitting, reduces costs, has good strength bearing properties and requires fewer patient visits. Analysis of the parameters and their impact on the time and cost of production of AFO was conducted. A layer height of 0.2mm was used with an infill density of 25% and with a speed of 50mm/sec of nozzle was used. The cost of the AFO using ABS came out to be 271.625 Indian rupees which is way less than 600-100 Indian Rupess used in traditional plaster moulding technique.
