I thought some of you might be interested in something I've been tinkering with. I really like the look of objects printed with a very fine layer height, however they take an age to print. I decided it would be great if I could 'Skin' an object by printing the outer layers with a very fine layer height but leave the inner layers with a thicker layer height. I've been working on some simple scripts that take a GCode file and post-process it to create the skin effect. So far the results have been very encouraging. The picture attached shows a 0.25mm sliced cube from Skeinforge (printed in 21m 30s) on the right. On the left is a 0.5mm sliced cube, post processed to skin it at 0.25mm (printed in 16m 0s). For reference the original 0.5mm cube without modification printed in 10m 0s. I've also just finished printing a 0.4mm carved object skinned at 0.2mm. The quality is not quite there, but my script doesn't do much other than scale down the 0.5mm extrusion values at the moment. Now I know that this approach has merit I'll continue to work on refining the scripts with an aim to see if I can turn them into a Skeinforge plug-in to make it part of the toolchain. There are more details on my blog here.
