When I saw Mattia Mercante’s War Machine Print, I had to give it a try myself, and after a lot of trials and tribulations I finally coming to a point where I can show off the results.
When I downloaded Joes’s models (I had to have them converted to OBJ by a friend, since I don’t have ZBrush), I realized that I was in for a lot of work.
The model is beautifully made, with a tremendous amount of detail, but it’s not really printable in that original state. There are tenths of thousands of individual parts in it that intersect each other, and there are parts that while they appear connected, they in fact not attached to each other at all. There are little bitty pieces that are so small they wouldn’t print at all, and other that would print, yet would be so thin, they would simply warp and break off.
With that in mind I loaded the model into MeshMixer and tried to thicken, merge, and otherwise connect that parts into a printable mesh. The model was so huge, that I couldn’t do anything with it without crashing, so I decimated it by 1/2, just so I can be able to load it and work with it. Even then, I had to up the RAM in my computer to 24GB.
Anyway, one of the tings I wanted to do, is retain a lot of the small detail the model has especially in the areas where the outer skin had been torn and you can see the wiring and mechanical parts. I separated the model into lots of small parts, but then recombined some for printing. For the final prints I had the torso, arms, head, mini-gun, ammo belt, pelvis& thighs, and legs. In all 9 separate parts. The parts were printed at 1.4 times the size of the original model.
There’s an iPhone 4 in the first image on the left, to give an idea of the scale. From the tip of his right foot to the tip of the minigun, it’s 11" long.
After the model cured I gave it a coat of flat black paint, which really made the details stand out
The next thing I need to print is the rock it stands on, but when I check it out in Preform, it would have used more than 1/2 a liter of resin, so I’m not quite ready to concede that for a rock, so for that I will use my Soldoodle FDM printer.
