SHAREPAIR

How do we stimulate people to repair their devices, instead of throwing them away? How can we make repair easier and more attractive? In the European Interreg project SHAREPAIR, design researchers from TU Delft work together with neighborhood repair cafés to find answers to these questions, especially investigating how 3D printing can facilitate repair.

Societal challenge: Sustainability Main disciplinary perspective: Technology

This project aims to decrease waste from consumer products by scaling up citizen repair initiatives through the use of digital tools. These tools collect repair solutions and make them easily accessible to everyday people. They will target both ordinary people at home and skilled repairers in repair cafés. 

The role of TU Delft’s Sustainable Design Engineering team is primarily to enable 3D printing for repair.  First, we identify current opportunities and obstacles, then we develop digital tools and training to assist ordinary people in using 3D printing to repair their broken household products. This will include an open-source database of 3D part designs for printing replacement parts, as well as tutorials for people to learn the skills needed. It will include how to 3D model replacement parts, print them, determine quality, and perhaps redesign replacement parts to upgrade their products or compensate for the lower mechanical performance of 3D printing materials compared to the product’s original materials. 

The objective is to decrease Waste Electronical and Electronic Equipment (WEEE) by 10% in pilot repair cafés, for a total of 15 tonnes of waste avoided per year. Additionally, SHAREPAIR aims to avoid 0.5 tonnes of WEEE per 1,000 inhabitants in the pilot cities. Ultimately, this would result in a total of 100 tonnes of waste avoided per year.

Jeremy Faludi is an expert on 3D printing for sustainability and Bas Flipsen loves to fix stuff.

The broken switch from a kettle was replaced with a 3D printed PLA bioplastic version. Because of the different materials and manufacturing, the switch had to be reverse-engineered with a slightly different shape.  That required testing and design iterations.

3D printing for repair can not only make products as good as new, but better than new, by adding personalization or new functionality.

The 3D Printing For Repair Guide

A tutorial providing a thorough step-by-step framework for do-it-yourselfers or businesses to repair ordinary household products with spare parts that you design and 3D print yourself.

The 3D Printing for Repair workbook

a companion to the tutorial that helps you go through the steps in the framework, with spaces to write or draw the information or designs you need at every step of the way.

Several Instructables on details of 3DP4R, including handling snap fits, simplifying part geometry, partial repair with controlled destruction, parametric adapters, and universal parts.  Also, two Instructables on the overall 3DP4R process that’re precursors to the guide above.

The holistic textile design research of Holly McQuillan

As a fashion and textile design engineer, IDE researcher Holly McQuillan wants to change the fashion industry by introducing it to the woven textile-form technique, a kind of 3D weaving which involves creating three-dimensional form by using the weaving process. Through this she wants to make the industry more sustainable by providing realistic tools. “Automated 3D weaving increases control and flexibility, and may make production more cost efficient.”

Disassembly: Essential to repair

Legislation can stimulate repair. But screws hidden so deeply in a product that they are nearly inaccessible are a repair nightmare. Bas Flipsen encourages circular product design by developing tools for designers and engineers.

Dashboard sparks the growth of urban greenery

Greenery makes cities more liveable. But how do you ensure urban greenery flourishes? Sanne Keizer devoted her graduation project to unearthing this answer, and in doing so designed a dashboard that monitors and predicts the evolution of urban greenery. "Urban greening needs more than a four-year policy period to be flourish," she says. Sanne’s project received a perfect score.
