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.

I recently got back from a trip to New York, having been there during ICFF and all the design week activities surrounding it. I was somewhat surprised at how little rapid manufactured furniture there was within the main show (unless you count laser cutting, which was impossible to avoid and demonstrated little that wasn’t being done five years ago), but outside .MGX was again showing it’s new collection at Moss, this year entitled E-volution. I should say straight off that the curation of this exhibition isn’t particularly clear: some of the pieces on display are from previous collections, and not everything in the new collection is on show. Nonetheless, it occurred to me whilst walking round that the designers and pieces involved fall into three distinct categories of the exploration of design for rapid manufacture.

Following on from Shapeways, which was spun out of a Philips research project, another Eindhoven-based company offering consumers the opportunity to design and manufacture their own products is studio:ludens. Started by Wouter Walmink and Alexander Rulkens, studio:ludens’ aim is to give people “the tools to create by using our skills as designers and our knowledge about the production process.” Like Shapeways, and ZapFab and FluidForms before them, studio:ludens have developed a set of interface tools which guide consumers through the creation of a product. Where studio:ludens shines though is in the quality of those tools, which without doubt are the most elegant and polished of all those I’ve seen so far.

Currently two design tools are available, the first, epa:kato, creates individualised drinks coasters, whereas lux:creator (still currently in development) allows consumers to design their own lamps. Both tools are Flash based which means clicking the browser’s back button will take you out of the tool, losing any designs that haven’t been saved. Causing the tool to automatically open in a new window would be an easy way to solve this.
