Reflections

Here is the first of three new prints I have been working on recently.

'Reflections' came to my attention when Bruno Birkhofer posted a different picture on Google+ last week. All his pictures are beautiful but, once again, it was one of his black and white portraits that inspired me to try another sculpture.

Modelling the pose in my favourite character modelling program was fun, as usual, but it proved particularly tricky to place the hands in exactly the right position. Several of the joint movement ranges have to have their range limitations turned off just to get close. 

In a moment of over-zealous optimism I decided to replicate the model's facial expression and kept the eyes closed but the mouth open. This involved a significant amount of cleaning up in Blender for a detail that ultimately proved too small to show in the final print. 

Not to worry - one day I may be able to sell these models and perhaps I'll even be able to afford a nice high-resolution DLP printer like the Kudo3D and then they will look even better.

I'm now getting the hang of using Simplify3D to slice my models so that the support material is placed where it's needed. The only thing I got wrong this time was placing insufficient support underneath the ponytail. The tip broke free during printing but fortunately the print managed to correct itself leaving enough to look reasonably OK.

Here's a couple of photos of the final print using translucent coffee-coloured PLA from 3D Filaprint, at 0.1 mm layer resolution with support enabled.

Body Language

I have just completed one of my best projects so far. It was inspired by another great Bruno Birkhofer photo called Body Language.

I took special care with the pose modelling to capture the lines as faithfully as possible, carefully placing the limbs as close as possible to each other without overlapping. I reused a short hair style of my own creation.

Here is a screenshot of my version in Blender.

The next important step was deciding how to print it and what kind of support to generate. I used Kisslicer to generate the printer files again, because although a new version of Slic3r has just come out with supposedly much improved support generation, I haven't had time to test it yet.

I decided to to make one change from the settings I used for the previous Birkhofer print and that was so go up from Medium to Dense for the support layer, just to see what would happen.

The other genius idea I had was to turn the print vertically for printing, which changed the position and amount of support material required. If I had printed the model exactly as it appears in the picture above, all of the chest and head would have need support underneath it. By rotating it to a much more vertical angle almost none was needed in these areas.

I was so impressed by the new settings that decided to make another video of the support removal process. You can see how my preferred tool is a flat bladed screwdriver which breaks the weak bonds between model and support with less risk of damage to the delicate areas. The support was certainly more dense than before and, in my  view, held the model better whilst still coming away cleanly.

Bruno Birkhofer

Last year, Thingiverse member, richgain, demonstrated the use of a camera and a 3D printer to make copies of the works of great artists like Auguste Rodin when he published his version of Crouching Woman. The resolution is not great and his method of using point cloud renderings from multiple photos loses a lot of the fine details but the essence of the piece is still there in the lines that the body describes. 

This, to me, is the point of sculpture as art.

One of the artists I have recently discovered during my research is fashion photographer, Bruno Birkhofer. I share his passion for the artistic shapes and lines that can be described by the body held in a beautiful or unusual pose. He captures his models photographically and freezes the pose in time but also selects just one angle from which the model will be viewed. My attempts to convert these great photos into 3D models aim to allow these forms to be appreciated from any direction and angle.

Looking back over the work I have done so far allowed me to reflect that one of the pieces I most enjoyed creating was Metamorphosis. I still think it's a strikingly dramatic pose. So, when I saw this Bruno Birkhofer picture I immediately recognised an opportunity for a new sculpture.

I have started work on the pose and, although it still needs some refinement, I'm pleased with the way it's progressing. The next stage is to begin cleaning up the mesh to make it printable and finish working on the hair.

I decided to print the model at a higher resolution than I used for Recline and opted for a 0.15 mm layer height. The print came out very well with only the underside of the horizontal surfaces looking rather ragged. This should improve with the final smoothing in acetone vapour.
