Because of all the detail, a T-800 head would be a cool way to test and see how much detail you can capture with this method. Plus if it works out that would be super badass having a metal terminator head.

Do you think it would be possible to cast a replica of your own skull (from like a medical scanner or something, plus some minor modifications to make it printable)? I think it would be both awesome and a little macabre to hold a replica of your own cranium.

[@yuki_foxsoul8425]

A few years ago it was trendy in Japan to have a 3D model of your unborn child. It was even available as a keychain. Your skull should then also be possible.

[@samarchist74]

That is such a cool idea?!!!

[@cletusburgerboy9143]

It is entirely possible, just be ready to pay a price to have your skull scanned entirely and then rendered.

[@rrrajlive]

Ans is Yes and No. Yes you can print it. No it won't be perfect at all. You need all the sutures and grooves of skull and joining which you can't get from a print.l or casting. Unless you're a medical student and very good at sculpting too.

In my projects Im gonna try next a castable 3d printing resin - Bluecast X5. Couple of coats and we will see how it will turn out

[@DizzyPanda]

there is an even better way, you can apply UV resin (3D printing resin) with a simple brush and let it cure in the sun, all surfaces will be smooth and it is way easier to apply than wax.

Hi. I have an idea. In order to prevent cracks while concrete cures, we can add glass fiber. Maybe you can do the same. Have 2 buckets, one with regular slurry and second with slurry mixed with glass fiber. Make every other coat with glass fiber. I thinks it should prevent cracks.

[@conecte-seainternet2831]

Have you tried using water soluble filament? Or would the slurry dissolve it?

[@alden1132]

I had a really cool idea for the skull! Drill small holes in the back of the eye sockets, to accommodate wiring for some red LEDs. Paint the inside of the eye sockets with an ultra-bkack paint (like BLK3.0 or Musou black). Then, instead of having the LEDS shining out uncovered, mount a concave disc/umbrella shaped shroud is ultra-black on the side facing out and silvered/reflective coat on the inside/LED side. That way, the disc/umbrella shroud looks like a super black pupil/iris, which is surrounded by a red glow. I think it would look incredible! Awesome video, keep up the good work!

[@sharkamov]

I've got a project like the one you're referring to, and let me tell you, LED's of that sort are really hard to come by, but I absolutely agree with your proposition, as it would ''enliven'' this magnificent sculpture in a _very_ special way! . . . 👌

[@MutohMech]

How did you restore the sutures in the back of the skull which the sprue was glued upon?

[@checkedoutchris]

Others may have already mentioned this, but I've had success "bubbling" compressed air into the base of the sand buckets to encourage liquefaction of the material. For me, it makes it MUCH easier both to add the silica sand during the first dipping steps (and help ensure even coating of the silica sand on the SuspendaSlurry) as well as preparing the support structure you mentioned being difficult when getting ready to pour into your pre-heated mold. GREAT work though! Love it! Please keep it up! :)

Even if you could make something in the exact right way authentic to whatever period you want to try to fool an archaeologist abbout, you still can't get it into the soil matrix without disturbing the context (and yes even baby archaeologists can tell when soil has been disturbed), making it essentially valueless from an archaeological standpoint.

Very nice to see that you tried my method of firstly melting out the excess of pla at 260*C and after that vitrifying and burning out pla leftovers and 900*C. And a little LoL - did you print it on heatbed itself without the buildplate ? When there is stricly said Do not print on this surface? 😂

[@walterbunn280]

I liked this. I've been thinking of making some aluminium bronze stuff for a while, and, even though this is a traditional tin bronze, there's probably many parallels. For the record, and somewhat tangentally, simply rubbing PLA with Scuply Clay (a type of PVC polymer clay) works very well at smoothing prints and still retains paint if you feel like painting it after the fact. It wouldn't work perfectly for lost PLA casting, but it works pretty decently for plastic figurines.

I have yet to make my foundry (will be looking to find a keg to convert like yours)... I was wondering what your thoughts are on the ability to use Lost PLA casting to create a 1:1 R2D2 dome? I'm assuming it would have to be cast in a few pieces then welded together (my plan is to use aluminium, which I'm aware is trickier to weld... but easier to source material for at little to no cost). Any suggestions/advice?

If you're feeling REALLY Ambitious, see if you can get your hands on a plastic Anatomically Correct Full Human Skeleton Medical model and use that to cast ALL the other bones in Bronze and then use the metal bones to recreate the plastic model... Other than it's weight, it would make a GREAT Halloween Decoration for your front window... Especially if you drill a hole in the back of each eye socket and add spooky red LED's...

Why not use an Investment plaster mold? It has very good detail retention, no leakage, and best of all, is water soluble (instant clean-up after 5-10 minutes of cooling). The only downside is the requirement to put in a vacuum bell to remove any air bubbles from the slurry.

[@josedacunhafilho]

Here is a concept idea for a series of products, since you have all the necessary tools, and the knowhow. People do a CAT scan of their own skulls, and send you the 3D file in whatever format you require. Then you can cast in whatever material each person chooses, and they can have their very own skull sitting on their desk. How creepy is that? I'd like mine in photo luminescent plastic, so it looks 'natural' during the day, and 'scary' at night. You can hire a couple of assistants just for that branch of production, and make some good money.
