This month has been about design and printing rather than twiddling with Huxley#710. I also ran a rapid prototyping course for my colleagues so they could appreciate some of the benefits and limitations of 3D printing technologies.
You can see the printed test object in PLA Faberdashery Village Green. I chose this colour for a number of reasons. The main being I had sufficient for the print, I also like the colour. But the second reason is our eyes are most sensitive to green / yellow additionally my camera seems to represent the colour well. Finally, it was in the printer as we also use it for printing Minecraft creepers, which the boys have been selling at school. The youngest forgot to negotiate with the manufacturer and was surprised the manufacturer had to make a profit too! More than one dimension to using a 3D printer, practical lessons in business, scheduling, bills of material, quality, design for manufacture, costing and so on!

We can't for example understand what influence the specifying geometry has interacting with the STL generation. Although not the principle purpose of the test, it would non the less be very useful. For example my CAD program has limited (crippled) STL output resolution for curves. You can see this sometimes where peoples STL curved features have steps in them. As the STL is after all generally triangular facets, the output filter will also usually set an angular resolution. As an STL object though, it has features which clearly 'stress' a slicing engine.
For the test object the following tools and settings were used for printing:
