3D Sierra Leone, a dutch nonprofit group, is offering personalized 3D printed prostheses to sufferers within the West African nation, with the help of SHINING 3D, a Hangzhou-headquartered 3D scanner and printer producer.
3D Sierra Leone is devoted to enhancing the lives of individuals in Sierra Leone that bear amputations however are with out entry to related medical care. According to its purpose, the NPO is utilizing 3D printing to create various kinds of prostheses for sufferers within the nation. As a way to scan the affected person’s stump and produce an correct, personalised gadget, 3D Sierra Leone is leveraging the EinScan Professional 2X Plus handheld 3D scanner from SHINING 3D, earlier than 3D printing the related prostheses.

Offering prostheses with 3D printing
In Sierra Leone, a lot of amputations are carried out attributable to complicated wounds attributable to site visitors accidents, severe infections and the delayed affected person presentation to the hospital. Moreover, many amputees additionally misplaced their limbs in the course of the Sierra Leone Civil Struggle (1991-2002).
A majority of amputees within the nation are with out entry to prostheses attributable to a lack of awareness, availability of supplies, skilled workers and excessive prices, which might actual a bodily and psychological toll on the person. 3D Sierra Leone explains that, with a prosthesis, many amputees can really feel extra at dwelling within the society that they reside in, overcoming problems with jealousy, insecurity, and despair.
In response, 3D Sierra Leone recognized 3D printing as a helpful and important software for manufacturing regionally related medical aids for folks within the nation, akin to braces, splints and prostheses, at an affordable value. The group is due to this fact collaborating with the Technical Drugs course on the College of Twente, and underneath the steering of the 3D lab on the Radboud College Medical Centre, to arrange a 3D lab within the Masanga Hospital in Sierra Leone.
The 3D Lab is operated by Technical Drugs college students from Dutch Universities TU Delft and College of Twente, who collaborate with native physiotherapists and prosthetic specialists. The lab is run with a deal with collaboration and information trade between the native inhabitants and Dutch researchers. 3D Sierra Leone additionally has plans to incorporate Sierra Leonean college students within the mission as a way to create a coaching place for the native inhabitants.

A sustainable course of to help the native inhabitants
3D Sierra Leone’s course of for designing and manufacturing personalized prostheses is concentrated on sustainability, as a way to make sure the gadgets are inexpensive for the native inhabitants and the mission could be carried out by the native inhabitants itself. As such, prostheses manufacturing has been made as standardized and easy as potential, and may thus be accomplished in a brief period of time.
Initially, the affected person’s stump is scanned utilizing the EinScan Professional 2X Plus, which takes round 20 minutes to incorporate preparation of the scanner and scientific inspection of the stump. A design of the prosthesis is then produced in round 30 minutes utilizing Meshmixer software program, earlier than 3D printing of the gadget takes place. Extra prosthesis components, like toes, are made out of regionally sourced wooden. After quite a lot of physiotherapy classes, an aesthetic cowl is made, in order that the prosthesis seems to be like an actual leg.
4 case examples within the 3D Sierra Leone mission have been shared utilizing the strategy above, with the approval and authorization of the events and their households, within the American Journal of Tropical Drugs and Hygiene (Vol. 102, No. four, pages 905-909). The primary two case research are examples of arm prostheses which have been utilized by the sufferers’ for each aesthetic and sensible functions. One of many case research particulars an arm splint 3D printed to help the therapeutic of burned contractures across the joint of a kid. The splint was essential to make sure the burns may heal with out contracting, which might restrict the joint’s means to maneuver. Lastly, the fourth case research pertains to an orthotic brace for a kid with a situation referred to as kyphoscoliosis, an irregular lateral curvature of the backbone.

3D printing has proved a great tool for offering needed medical gadgets and provides in areas with restricted entry to them, significantly with reference to prostheses, which could be tough to supply. For instance, in 2017, the Allow Group Basis (ECF) used 3D printing to create prostheses for folks in Haiti as a way to deal with the massive variety of upper-limb (UL) amputees within the nation.
In Syria, 3D printing can be getting used to present prostheses as historically manufactured gadgets are laborious to supply and ship to the nation amid the continuing Civil Struggle. Syria Aid, a UK-based charity working in Syria, has pleaded with the UK’s Division for Worldwide Growth (DFID) to supply funding for 3D prosthetics for kids within the nation.
