3D Printing for Repair

An Approach for Enhancing Repair

Journal article (2023) - A.A. van Oudheusden, J. Bolanos Arriola, Jeremy Faludi, Bas Flipsen, R. Balkenende

The availability and storage of spare parts are the main barriers to product repair. One possibility would be to 3D print spare parts, which would also enable the repair of products not intended to be repaired. Besides manufacturers, 3D printing spare parts is an interesting o ...

Opportunities For 3D-printable Spare Parts

Estimations From Historical Data

Conference paper (2022) - K.T. Samenjo, A.A. van Oudheusden, J. Bolanos Arriola, Bas Flipsen, Jeremy Faludi

The Sharepair project aims to decrease the waste of electronic and electric consumer products and increase their useful life, by supporting repair communities and scaling up citizen repairs through digital tools. One of the focus areas of this project is to support the discovery or manufacturing of spare parts. With a 3D CAD model of a part and a 3D printer, repair communities could manufacture spare parts. This paper discusses the possibilities of identifying repairs, within repair communities, that can be met through 3D printed spare parts. To understand and identify these possibilities, the repair entries expressed in the Open Repair Database (ORD) from the Open Repair Alliance were examined. The analysis aimed to identify documented examples of repairs that have broken or missing parts, and estimate how many may be suitable for replacement by 3D printed versions. The ORD includes 41,874 repair data entries from 229 repair communities (Repair Café, Restart Project, Fixit Clinic, and Anstiftung) in eighteen countries. Repair entries include information such as product category, brand, model, repair status and notes regarding the repair process and result, all in different languages. The analysis identified a list of the most commonly repaired product categories, brands, and models, as well as an estimate that between 7.5% and 29% of products in repair cafes that are not repaired today could be repaired with 3D printed spare parts. The analysis also showed that the data and information about the repairs is inconsistent, open to interpretation and often too limited to precisely pinpoint opportunities for 3D printed spare parts. Specifying the product parts that need repair or replacement and their functional requirements would be key to a successful identification. Thus, the study proposes recommendations to improve the process of capturing repair information that specifies the repair needs that can be met by the use of 3D printing.@en

3D Printing for Repair Guide

Book (2022) - J. Bolanos Arriola, A.A. van Oudheusden, Bas Flipsen, Jeremy Faludi

This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is a ...

Further development of the Disassembly Map, a method to guide product design for disassembly

Conference paper (2020) - F. De Fazio, J. Bolanos Arriola, S. Dangal, Bas Flipsen, R. Balkenende

The Disassembly Map is a modelling method which allows to visually represent the architecture of a product, describing disassembly precedence and dependencies of components and operations necessary for their complete non-destructive removal. It introduced new standard visual elem ...

Quantifying the total cost of ownership by modelling product lifetime

Master thesis (2022) - R. Manivannan, Jeremy Faludi, J. Bolanos Arriola

Consumer products produced in contemporary times face the issue of deteriorating durability, repairability and service life compared to products of yesterday. This deterioration is part of a bigger issue called planned obsolescence. Due to a ‘need’ to buy new products regularly, there is rampant consumerism which has created a decrease in raw-materials and an increase in the products and materials entering the waste streams. Therefore, it is imperative that this “cradle-to-grave” model is stopped. The EU and various governments in the EU have proposed legislation to transition from today’s linear economy to a circular economy. As part of that, there is greater emphasis placed on a product’s repairability, durability and product lifespan.
Repair scorecards are used to evaluate products on those parameters. However, the current scorecards have abstract scores that are difficult to interpret. Therefore, this thesis proposes a quantitative tool that calculates the total cost of ownership (TCOO) and service life of a product by modelling product lifetimes using failure modes.
This thesis begins with performing a literature study of linear economy and planned obsolescence, current scorecards, and their limitations. Questionnaires and interviews were conducted to understand what consumers wanted from a repair scorecard. The results from these were used to design the label and website of the TCOO tool. A system was created to facilitate the TCOO Excel tool, label, and website.
The mathematical model to calculate the TCOO was built-in to an Excel tool, and sample data was used to iterate upon them. Sensitivity analysis was also conducted to test the Excel tool. User tests were conducted to test if the Excel tool was intuitive to use and the flow of the tool iterated upon. User tests were conducted to refine the design of the label and the website.
The main contribution of this thesis lies in presenting the factors of repairability, durability and product lifespan in terms of cost, modelling product lifetimes, and moving from a priority component-based calculation system to a failure mode-based system. Using this tool, consumers can make informed purchase decisions, and manufacturers get data regarding failure, and legislators get data to introduce new laws and mandates.
