A milestone in 3D printing

Here comes the copyright infringement question concerning 3D printed objects. As 3D printers are getting much less expensive, one can expect a soon to be time when a certain number of objects will be home made. Of course, objects can be designed with a 3D software, but a shortcut would be to scan the original piece and simply copy it.

But we can expect finding online specialised sites which will offer, free of charge or for a small amount, ready to print 3D files. This new market will probably bring up the same problems we are witnessing with music and video downloading:
As soon as some smart ass will create an equivalent to DivX/ MP3 compression standard, 3D files will be easy to get and millions of artefacts, originally designed and produced by industries, are going to be scanned, available and shared online.

While the already obsolete war on piracy is on, it seems that no one has yet anticipated the forecoming problem, as well as the complete market revolution that will occur. Cheers!

A very interesting illustration: The Penrose triangle

The Penrose triangle, also known as the Penrose tribar, is an impossible object. It was first created by the Swedish artist Oscar Reutersvärd in 1934. The mathematician Roger Penrose independently devised and popularised it in the 1950s, describing it as "impossibility in its purest form". It is featured prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.

The tribar appears to be a solid object, made of three straight beams of square cross-section which meet pairwise at right angles at the vertices of the triangle they form.

How to draw the impossible triangle

Made from three 8-inch boards of wood.

It was done in AutoCAD R14

Using Solidworks

In SketchUp
