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.
