Additive manufacturing advances customisation and design flexibility. Increasingly, Rapid Prototyping technology is being used within footwear fabrication applications. This project develops competencies across our university and provides designers and podiatrists with an understanding how 3D printing and app design can modernise existing practice and create a novel solution to more effective and repeatable insole/orthotic therapy and wellbeing of our feet. In a two part assignment product design students have been tasked to design 3D printed custom insoles for footwear that can be fitted with force sensors. Digital personalisation in the form of an app allows users to measure their feet via 3D scanning, or monitor posture, pronation, gait and pressure points. User interface (UI) and user experience (UX) will be investigated to develop a crucial awareness and understanding of the relationship between the human factors, wellbeing and good design. This presentation maps the initial findings of an undergraduate Design Project so to build up interdisciplinary research capacity around health-related customisation, working with colleagues in Health Professions/Podiatry and potentially benefitting our Physical Activity &amp; Life Sciences Research

User-Centred Design Innovation - Developing Smart Insole Solutions through 3D Printing and App PrototypingBy Friedemann Schaber, Michael Wright and Connor Ratclie     https://mypad.northampton.ac.uk/researchconference23Academic Poster           University of Northampton 2023 Research Conference  27-28 June 2023IntroductionAdditive manufacturing advances customisation and design exi-bility. Increasingly, Rapid Prototyping technology is being used within footwear fabrication applications. This project develops competencies across our university and provides designers and podiatrists with an understanding how 3D printing and app design can modernise existing practice and create a novel solution to more eective and repeatable insole/orthotic therapy and wellbe-ing of our feet. In a two-part assignment product design students have been tasked to design 3D printed custom insoles for footwear that can be tted with force sensors.

It also takes a snapshot of a dynamic structure that needs to change position and shape throughout gait (there is no agreed upon casting technique or position)3D printing would provide a solution to modernise our existing practice, and create a novel solution to  more eective and repeat-able insole/orthotic therapy FindingsThe project synthesis develops user centred prototyping practices at this university, by demonstrating an iterative model using a visual road map of user centred learning journey. Building upon two frameworks of innovation processes - i.e. the startup navigator of St Gallen University (Grichnik & Hess, 2020) and the UK Design Council’s Double Diamond Design Process (Ball, 2019), the project team developed a visual way to show the diering aspects of the project, in the form of an infographic, featuring steps taken during the collaborative innovation project and the feedback loops.What next? Create sample pads to be scanned and digitised into STL les that can be loaded and scaled to dierent sizesUtilising Product design existing work – commence printing of pads to match existing material densities and thicknessesOutcomes form project:Conrm printing parameters and lament type (ideally less lament types needed by modifying print parameters to change density)Conrm cost and proof of concept to digitise and accurately repro-duce on dierent scales/sizesConrm ability to make minor modications (grind/cut) and glue to each other and baseCreate a “blank” base (1 x at, 1 x with heel cup) to add pads to as needed (to allow for a closer feeling/functioning device to a fully printed version – once pt happy with temp)Conrm ability to scan and digitise temp for storage and subse-quent accurate repat printingConclusionCapacity building and changing practice at this university, by demonstrating a model using a visual road map of collaborative innovation and of user centred prototyping.Design and modelling of a 3D printed insole and screen-printed sensors. Exploring and evaluating additive manufacturing and insole customisation through a co-design approach with Podia-trists and Technician Demonstrators. The research demonstrates the rst version of a roadmap of user centred project innovation and collaboration at UON. The poster alludes to a potential supporting a future innovation pipeline and will be developed and honed to support cross collaborations. It will provide possible guidelines to support future cross-faculty collaborations and support students to develop disciplinary skills and digital proto-typing in Health Professions/Podiatry and potentially  Physical Activity & Life Sciences Research.MethodThen project provides the student with an understanding of anthropometric research and its use in ergonomic design together with the application of colour. User interface (UI) and user experi-ence (UX) will be investigated to develop a crucial awareness and understanding of the relationship between the human factors, colour and good design. The project is an introduction to prototyp-ing of screen-based applications using ‘wireframes’ and user experi-ence design tools for mobile apps. The user centered learning for students was over one semester based on the new product devel-opment (NPD) methodology, students’ networking with podiatry sta and applying their soft skills in a new context.    The project team included BA Product design students, three academics and three tchnicians involved in the workshop facilitation.Podiatry Clinic Visit App PrototypesStudent app and insole prototypes by Ella Sharwood, Tom Cottrell, Ben Hepworth, Joshua Chandler Technician Demonstrations by Jason Duggan (App and Video), Paul Tallon (3D-scanning & Meshmixer), Jayne Coreld (Screenprinting) 3d print settings.Filament addigy 2045 TPC lament 2.85mm diameter.temperature 240build plate  temp 65
