Unto This Last is a furniture studio and workshop, based on two sites in London. Its name comes from the title of a book by John Ruskin, published in 1862, in which he advocated a return to localised, craftsman/artisan workshops as an antidote to the conditions which industrialisation had imposed on much of Britain’s working class. As a fore-runner of William Morris and the Arts and Crafts Movement, Ruskin’s thoughts were influential, but the rising standard of living which mass manufacturing brought to the West meant that his pleas were ultimately seen as anachronistic. But according to Olivier Geoffrey, founder of Unto This Last, CNC machining and on-demand manufacturing open up possibilities for the craftsman in the community which may yet see Ruskin’s vision realised.

For the last month or so I have been teaching on the MA Industrial Design course at Central St Martins in London, on a project titled “manufacturing and consumption futures”. The project  is intended to encourage students to research the opportunities which new production methods allow for more personalised products, to propose and refine a system of their own, and ultimately to prototype the system itself. I hope to show some of the outcomes in a later post, but as part of the research for the project students were invited to Unto This Last’s Brick Lane workshop, to look around and to quiz Olivier about his philosophy.

Olivier began by explaining how, if you’re engaged in design, you’re inevitably bound up in the distribution systems of the products you’re designing. A designer working at Ikea, for example, doesn’t design flat pack furniture just for the sake of it, or even because it’s part of the Ikea brand experience. Flat pack systems allow customers to transport their purchases home from the store and then assemble the furniture themselves, which is crucial for keeping costs down. Whereas a designer working for Cassina knows that the assembly and transportation costs will be tied up in the price the furniture, and can therefore rely on skilled craftsmen using specialised tools to build a piece of furniture, rather than an untrained consumer with an allen key.

Unto This Last’s designs are similarly a reflection and a result of distribution systems and logistics. A customer who visits the store can see some examples of the products on sale, but with the exception of a few small gift items, no products are held in stock, instead they are manufactured to order. This reduces the costs of storage and inventory, whilst also allowing the company to carry more than 2000 items its catalogue. Orders are made in-store and delivered pre-assembled, and because the furniture is shipped direct from the store it means packaging is also greatly reduced. In this way, by using digital manufacturing processes and some of the techniques recognisable from other mass customisation initiatives, Unto This Last can offer custom-made furniture at close to mass-production prices.

Unto This Last uses laminated birch ply for all its products. Clearly the material has properties, both visual and functional, which many designers in the past have found interesting, and it would probably be naive to suggest that the only reason for using the material is its fit within Unto This Last’s distribution chain. Nonetheless, it is remarkably suitable for helping Olivier realise his vision. To begin with plywood is very dimensionally stable, and has uniform properties in all directions (unlike natural timbers, where grain and knots affect the strength and shape of the material). It also doesn’t shrink. This means that parts can be machined on a CNC router with a high degree of accuracy (typically Unto This Last manufacture to tolerances of 0.1mm); such precision also simplifies the process of assembling the finished furniture piece – less finishing is required, and glue dries under the natural pressure of the fit, without the need for clamping. Using laminates also allows Unto This Last to effectively design its own materials – both workshops (in Brick Lane and Battersea) have presses for applying ’standard’ veneers of oak, walnut, maple and a melamine coated surface, as well as allowing experimentation with bespoke surfaces such as fabric, leather and paper.

The use of birch ply laminates undoubtedly plays a part in the consumer acceptance of this way of working – because the material is relatively uniform it means a customer can be confident that the piece of furniture delivered to them will be virtually identical to the one they saw on display. But the material also has a significant impact on the both the designs of Unto This Last’s furniture, and the process of design which leads to them. Parts are designed which anticipate the requirements of production, they incorporate tapers, chamfers, clearances etc which can be machined rather than relying on a furniture maker to create joints and fixtures by hand. Design elements which are proven to work on one product are reused in new products, and so a vocabulary, both technical and aesthetic, has built up. All of Unto This Last’s products are built in Solidworks, and by using equation driven parameters a design can easily be modified such that changing one dimension will cause all other critical dimensions to update. The company has also put a significant amount of effort into developing custom API’s to calculate the most efficient way of laying out parts before they are machined.

How the constituent parts of a fully assembled piece of furniture are machined turns out to be a significant issue for Unto This Last. Not only does it make sense to save costs by wasting as little of a laminated sheet as possible, businesses in London have to pay per kg of waste, which provides another incentive to make efficient use of each sheet. Typically the workshop will take two weeks worth of orders, computer software then creates a ‘cutting map’ for each sheet of laminate required. Where it’s not possible to use an area of the sheet for furniture that has been ordered, smaller gift items are incorporated into the cutting map to fill up the empty space. Again this demonstrates how Unto This Last are almost obsessive in the use of digital technologies to refine the manufacturing process; this is the key difference, Olivier explained, to more expensive furniture makers where a significant amount of cost is tied up in waste and poorly optimized logistics.

Certainly the concept of a craft workshop in the centre of a city, enabled by digital technologies, where customers can see and hear and smell custom furniture being made, seems to have struck a chord: 40% of customers come from the recommendations of past clients, and a further 40% are people who just happen to see the store and are interested enough to look in. But Unto This Last goes against the flow of most mass customisation enterprises, which tend to be impersonal and usually offer no contact with the designer, and where cost reductions are achieved by off-shoring to faceless factories rather than opening an atelier in the middle of London. Just how successful Unto This Last is at realising Ruskin’s vision remains to be seen, but we’d have more interesting cities, and more interested customers, if it showed the way for others to follow.

Thanks to Olivier and Pierre for their time, and Ben Hughes for arranging the visit.

I recently received a mail from Alex Mamalyha, web community manager for i.materialise, announcing the launch of a new service from Materialise NV. i.materialise is a rapid manufacturing service aimed at designers, and the beta site gives a good idea of the way the service will work. Obviously there are many web-based rapid manufacturing services these days, and the announcement of a new one is a fairly regular occurrence which I usually just ignore. But given the extent to which Materialise have supported and encouraged designers’ use of RM technologies through their .MGX initiative, I thought this was one service that deserved further investigation.

The ‘manifesto’ of i.materialise claims the service makes “3D printing as easy as printing on paper”. Obviously such claims owe more to hyperbole than fact, but the i.materialise interface is presented in a relatively simple and obvious way. A workspace in the centre of the screen visualises the model once it is uploaded, and a number of drop-down menus to the right give the choice of materials, surface finishes etc.

To test the service, I used a model I made previously for Nina Pirhonen, a Finnish designer and creator of the PomPom character and series of books. The model was originally created in Solidworks, but in order to upload it to the i.materialise site it first needed to be converted to .stl format.

This post deals with the results and conclusion of the user trial discussed earlier. The findings of the study can be divided into two main areas: the results of the drawing exercise and the success of developing the drawings into a 3D CAD model, and the results of the two CAD modelling exercises. It’s important to stress that in both cases the objective was not to judge or analyse the quality of the design, but rather to gain subjective feedback from participants about which activities they enjoyed or disliked, and which approach resulted in the product they were most happy with.

From Configuration to Design: Capturing the Intent of User Designers is the title of a paper I recently presented at MCPC 2009 in Helsinki. It details a user trial conducted as part of my PhD research, which sought to understand the extent to which non-professional user-designers are able to engage in design exploration and to communicate design intent. The paper itself, together with the presentation given at the conference, can be downloaded from the Papers and Presentations page of this site. Much of the background argumentation to the study has been made in previous posts, therefore what follows is an edited version of the paper, focusing on the design, conduct and conclusions of the user trial. This first post deals with the design and conduct of the study, a follow-up post will concentrate on the results and conclusions.

Design of the Study

The focus of the trial was the design of a USB memory stick. This was chosen as a relatively simple product whose functionality was easily recognised by those who took part in the study. The trial was intended to investigate two main research questions:
What is the best method for consumers to conduct design exploration?
How well are consumers able to communicate design intent?

It built on the observations of a number of researchers with regard to the way designers and architects use drawing as a way to generate and evaluate design solutions, but sought to place such observations more specifically within a mass customisation scenario. It also sought to understand the practical difficulties of expecting non-designers to use drawing in the same way that trained designers do. The intended outcome was to better understand what future tools will best enable consumer-design, which will form a major part of my future PhD research.

Day two of the conference started with a keynote by David Gross and Jeff Beaver of Zazzle, together with James Johnson of Avery Dennison. Zazzle and Avery have recently launched a collaborative effort, the first example of which allows consumers to customise and order ring binders in a minimum quantity of one. In this instance Zazzle is acting as a ‘gateway’ to Avery’s manufacturing capabilities, with Avery producing the custom binders at their own facilities. James Johnson described clearly some of the challenges involved in setting up a mass customisation enterprise inside a business which has always excelled at mass production – Avery had already tried it’s own MC initiative before collaborating with Zazzle, but three days after the partnership launched there were 60 times the number of user-created designs than Avery had attracted in a year.

Looking back at my report on 2007’s MCP conference, I can see that I was somewhat disparaging of Zazzle, who I compared unfavourably to Ponoko and Threadless. Following this presentation I was much more impressed by what Zazzle has achieved and how fast they are advancing the benchmark of what consumers expect when customising products. For example, Zazzle has invested in body mapping capabilities more commonly used for special effects in the film industry, this allows custom clothing to be presented in a much more realistic way, with designs mapped onto folds in the fabric. And within the Zazzle system, users can open their own stores, setting their own prices for products and (in some cases) running a full time business by customising, and allowing others to customise, their designs.
