Photo finish

Here are some photos of the prints from 'Casual undress' and 'Crouch' after finishing with the acetone vapour smoothing process.

Casual undress

Right, I think it's time for an Entiresia original.

I have a pose in mind and I'm going to have a go at creating it from scratch. I want the woman to be relaxing casually on her side, head propped up on one arm with the other hand reaching forwards and resting on the floor. I also want the knees tucked up a bit and both feet resting on the floor.

I started by positioning the right arm and then the head and neck. Next, I added a bit of forward bend, lateral flexion and slight rotation of the spine, to make the right hand side form a straight line, as if lying on the floor. The model was then rotated almost 90 degrees to the right, into the reclining position. The breasts were repositioned slightly to show the effect of gravity pulling from the right side and then the legs and the left arm were placed in contact with the floor.



This pose was also designed with 3D printability in mind, so should require a minimum amount of support.

I did the slicing in Cura with my usual setting of 0.15 mm layer height and 25 mm/s print speed, although I think I could have gone a bit faster. The steep angle on the left forearm caused a bit of curling of the leading edge so I had to use a small amount of cooling fan (sometimes it helps, even with ABS) to prevent the nozzle from crashing into it. I took the temperature up to 240C this time and was very pleased to discover that this print has absolutely no sign of splitting anywhere.

After a bit of sanding to clean up the support marks I took this series of photos, making the most of the low morning sun - vapour smoothing to follow soon, I hope.












Crouch

I have a good friend who we visited recently, who has many fine pictures and sculptures in her house, many of them art nudes. One small sculpture on her mantelpiece caught my eye as it looked both original and printable.






Here is the STL file, processed in the usual way, ready for printing.




I used Cura for the slicing, both for its support and ability to fix overlapping meshes (Project Miller has now ceased to function!)
I decided to print in black ABS and use vapour smoothing on the finished print. This version was printed inside the heated chamber at a slow 25 mm/s and 235C. 
There is one small split across the back which I hope will improve with acetone treatment.

I have another project in the pipeline (well, in the printer actually), so I'll wait until that's finished and then start a smoothing session on both of them.
