Architecture and Structural Engineering, textile roofs: "Generation of Cutting Patterns"
Generation of cutting patterns is the process conceptually analogous to the problem of creating maps of the surface of the earth meaning the creation of planar cloth geometries from doubly-curved form-found surfaces. Obviously, whatever technique is used, introducing distortions is an obligatory step in achieving desired results. However, it is common for more distortion than necessary to be applied, and for the distortion to be badly localized. Preferences should be given to the strategies which, as well as providing the highest quality patterns, enable sophisticated monitoring of the distortions due to the enormous variety of patterning situations.

08Apr08 by Matt Sinclair"
So far I have looked at ways in which rapid manufacturing technologies might become available to consumers, and the reasons why product design for rapid manufacturing is easier than for mass manufacturing. In the final part of this extended post I want to address the only other remaining hurdle to consumers designing and manufacturing their own products: the tools they will use to design with.
Consumer co-design, sometimes called co-creation, is a topic that’s been written about at length by design researchers. At it’s purest it involves the end user, or typical representatives of end users, entering the design process and creating products or services as part of a design team. In practice though, co-design is often little more than an enhanced customer research exercise. End users might be asked about their needs and desires, encouraged to offer suggestions, and even invited to critique proposed solutions. But there is no doubt it is the designers who are expert, and who make the final decision.
As a designer myself, I confess I find it difficult to break free of this mindset – surely my training and experience mean I am able to understand what a market of consumers will want better than an individual consumer themself might? But the point is, what I think will end up being irrelevant if consumers are able to design their own products. Why should a consumer care that I think their product is crass or crude, if it’s exactly what they want, and they’ve made it? At the moment though, I have one trick up my sleeve – I can use CAD, to design a product and to communicate that design to the means of production, in a way that no non-designer can. All the time designers and design engineers can monopolise the expertise needed to create CAD data, consumer created products will not happen

Gauss Map and Curvature - Wolfram Demonstrations Project
The Gauss map maps the unit normal of a surface (on the right) to the unit sphere (on the left). The area surrounding the point on the surface is thus mapped to an area on the unit sphere. As the radius of the loop approaches zero, the ratio of these areas approaches the Gaussian curvature of the surface at the point, which is also equal to the product of the principal curvatures (the maximum and minimum curvatures of the normal sections through the points).
Select a surface from the top pull-down menu (a description is given in the menu, but the function is displayed on the button). A point may be selected by moving the 2D slider. The Gauss map maps a loop around the point onto a loop on the unit sphere. Move the "normal" slider to observe the following: Looking down the normal vector, if the surface has positive Gaussian curvature at the point, the loop on the unit sphere is traversed counterclockwise (positive direction); if it has negative curvature, the loop is traversed clockwise (negative direction). About a degenerate saddle point, the loop may wind more than once on the Gauss sphere for each time around the point on the surface. Move the "radius" slider to observe the following: The loops will change size. As the radius of the loop approaches zero, the ratio of the surface areas contained by (1) the loop on the sphere (counting orientation and multiplicity of the loop) and (2) the loop on the surface approaches the Gaussian curvature of the surface at the point.
Below the graphics is some curvature data. The surface areas contained by the loops, their quotient, and the Gaussian curvature are given. Further, the Gaussian curvature is equal to the product of the principal curvatures, which are defined to be the maximum and minimum curvatures of the normal sections through the point. The normal sections corresponding to the principal curvatures are shown in the surface graphic.

Stand Up Architecture: Freeform surfaces from single curved panels
Since I found out last week that the proposed system only can be used to make single curved surfaces I started searching for methods (for example a Rhino Plugin) to convert a freeform surface into single curved (developable) panels.
I found out that Rhino has a method for lofting developable surfaces on basis of polygons, curves or Bsplines. I tried this method to loft some Bsplines into developable surfaces, but I experienced some problems, especially with lofting complex shapes. In these cases, the method doesn’t produce very fluent shapes, in comparison to double curved lofting methods.
On the internet I found a very interesting paper called 'Freeform surfaces from single curved panels'. The paper describes a method to approximate double curved surfaces by single curved D-strips (click here to read this paper). The method was developed by H. Pottmann. Besides the geometrical explanation of the method, the papers also shows some very convincing examples of freeform shapes which are constructed out of developable (single curved) D-strips............"
Lamina Design
Lamina 1.0 makes it easy to fabricate large scale free-form structures from planar (sheet) materials like plastic, metal, or plywood. This fabrication technology can be applied to interior design, building architecture, lighting, signage, clothing, and sculpture.
Lamina 1.0 uses computer methods to build precise physical structures in the real world. Your 3D model is approximated by a number of 2D parts that are numerically cut and attached to fabricate the final structure. Laser cutting, abrasive waterjet cutting and plasma cutting services are widely available and make creating parts inexpensive and fast."

Rambølls nyindkøbte 3D-printer fremstiller gipsmodeller med udgangspunkt i 3D-modeller udarbejdet i et CAD-system. Den håndterer både farver og materialer, som følger med modellen.
Materialet er gips, som bliver limet sammen med farvet lim, og det er hemmeligheden bagved de billige priser. Printeren læser CAD-modellen lag for lag og giver mulighed for at fremstille de mest komplicerede dobbeltkrumme flader, uden problemer.
Har du modeller, som du gerne vil have printet, kan du sende dem til vurdering og få oplyst pris og leveringstid. Vejledende priser finder du her på siden. Du kan sende din model til Thomas Lundsgaard.
