Iron Man MK-42 helmet - 1/2 scale

Postby watsonstudios » Sun Mar 02, 2014 1:09 pm

Here is something I printed last night. Took about 5 hours to print. Using a new formulation from MakerJuice. It had some strange holes develop on one side, not sure why they didn't appear on the other side or anywhere else because the walls are the same thickness throughout. The walls are very thin, probably too thin for this scale but turned out pretty well.

I did over sample the slices about 3.5x then scaled back down in Photoshop. There were 1389 slices total. Each layer exposed for 9.5 seconds - total layer time 13.5 seconds.

Good side!

The rings are nice & smooth. Without over sampling, these rings would be jagged or "stepped."

It actually looks way better than I thought it did. The side that turned out is pretty nice, forgot to ask what resolution (Z) did you print at?

Well unfortunately it's not my model to share so I can't at this time. The actual build size was 138 x 93 x 141mm.

Hi Watsonstudios,

That is a beautiful print! I'm very interested to test using over-sampled images. What process are you using?

Thanks,

Craig

Thanks! Are you sitting down? Haha.
1. I have my model.
2. Bring into B9 Creator software to add supports (will be switching to CW soon)
3. Bring model into Viscam RP to cleanup & slice. This step also merges all the supports and part into one mesh.
4. Save the slices at 600dpi BMP files (my native dpi for my prints are 170dpi)
5. Batch process in Photoshop to resize all the slices back down to 170 dpi or 1024x768
6. Open MS PowerPoint. Create a photo album with all the slices. Save as .pps file
7. Run a custom macro in Mach3 which runs the slideshow from PowerPoint and controls the printer.
8. Hit go! :)

That's about how I do it.

Is this a new revision of Sub G+? How is it different?

I guess it's a thicker, less shrinking formulation. It may be his new SubFlex formula which is still in beta. It is a softer, more flexible resin, even at full cure. Josh just sent me some to try out. I had expressed my concerns about the shrinkage of SubG+ so he was going to try out some new ingredients for a more stable resin.
