This is a simple dice with a skull-shaped void inside it. In order to see the skull you need to use a transparent print process. Theoretically SLA should work (but lacking an SLA printer I haven't tried). For FFF printing, Colorfabb HT will work if you can print it hot enough and have an enclosure and can turn off the fan and turn your settings down to print fairly slow. See the video for ideal print settings.

This must be printed without supports or it will ruin the void.

There's still some question about orientation. The skull can't print facing up, the eye holes need support, so should I print it on the bottom or the side? The bottom tends to be very clear, but if you haven't had a perfect purge that's a no-go. But on the side any bubbles in the print become very visible. There's no clear answer to this one, pun intended, but I think if you printed these I'd say skull down, and that's how I uploaded it.

I can't seem to get this right, is it at all possible with PrimaSelect PLA Natural filament?
Four tries so far with different settings and I just can't get it to be translucent.

I don't know if PLA can do it. My guess is you'd have to turn off the fan, but I don't know if it's even capable of the capillary action to get down into the holes of the previous layer. You'd have to keep it liquid so the bubbles could get out, and I'm not sure that's a good idea with PLA the way it crystallizes different than other polymers.

Let me know what you've tried.

I've been fumbling around with different values for temperatures, Thickness & shell count, solid infill layers, fill density, different speeds etc.
I have some neat results but either the die is too brittle or the shell is obfuscating the inside too much.

I might just go down the path of designing my own die with a unique design on one of the sides instead. It was fun tinkering for a while, I've just gotten into 3d-printing and my flashforge inventor II is running smoothly for now :)

103% exrtusion better?

I did manage to print this using a Form2; @20mm it's about 8.56ml of resin just under 2hours. I had some remaining in the bottom tray before swapping to a different cartridge so I did a test... unfortunately some clear resin still remains on the inside of the hollow after the print which is to be expected as the Form2 "drips" the resin off as the model/build platform is submerged into the resin chamber layer by layer. Essentially the model looks like there's water trapped in the middle of an ice cube - skull is still visible but obscured by the trapped resin.

I did modify the model to include a small hole that connected to the interior skull from the outside that could allow for the liquid resin to drain or to clear/rinse it with some isopropyl alcohol so we'll see how that works out - it will take a while, even with agitation, since the hole is .25mm. The hole is hardly noticeable as it exits through one of the pips from the other side. It may need two different airholes to allow forced air/liquid to clean out the hollow part... maybe it could accept some die or ink injected via a syringe - may be too much trouble in the end (LOL). It was a fun exercise that might have some interesting applications down the road depending on the model/prototype...

Can you post the updated model please?

posted a remix; good luck!

Thanks! Im going to try it on the Form 2. Let you know how it works!

Thank you so much for trying this. It was the one test I wanted to know how it would work but couldn't do.

Seems to me a better idea might be to make the hole a little bigger, but be clever about it. If I ever get an SLA printer I'll give it a shot.

yeah; currently the hole comes out of the top of the skull; if you swapped the pips for 3 and 5 putting them across from each other and rotate the skull you could put two drain holes coming out the top/bottom or left/right (ears) of the skull allowing it to drain from one center pip of one side through the other... wouldn't go too much bigger since you might be able to see the drain holes (although coming through the chin through the top of the head might be interesting looking), you could make the skull a little larger on the interior and then the drain holes might not be as noticeable... I think some resin will always get trapped since the viscosity isn't as fluid/liquid. I may play around with it this weekend. This 'ice cube' effect might be interesting in models like jemstones/marbles that have shapes/bubbles trapped inside with liquid resin floating around...

Ok thanks, 100% filling

100% filling or ...........?

what infill do we need in order to print this?

100... are you taking the mickey?

How much for infill? 100%?

I kid, I kid. XD

really cool nice job!
