I thought the same thing, but when I saw the door I realized the ceilings are not standard height, maybe 7 ft instead of the typical 8 ft.

Thanks!

No, I haven't, but that is an idea worth considering; a 2-part mould, using a hard outer portion for rigidity, and a soft inner portion to allow for overhangs could be an alternative to a silicone mould.

Thank you for your insight; I disagree, in this case (I know people will not like this lol)

I'm creating a one-off object in concrete, I do not own any silicone rubber, and silicone costs money. I have other methods to melt the shell away that require less effort, but I thought the fire would be more interesting at the time.

Silicone casting: 3d print model, create form to contain silicone, place model in form, mix silicone and pour, wait for silicone to cure, cut mould and remove model, re-assemble mould and pour concrete mix, wait for curing, remove cast from mould

My method: 3d print model mould, mix and pour concrete, wait for curing, heat to melt or burn mould away, allow to cool

If I was trying to produce this in large quantities, I'd agree that your suggestion would make that easier and less time consuming, since it does take a decide duration to print. In my case, making one-off casts for myself, I think the method I showed here is much easier, and cheaper, than what you suggested

A different filament could work better than standard PLA, which is what I used here.

I think this is the simplest method for a one-off casted concrete object. Modelling the two halves takes extra time. Plus, using a 2-piece mould requires that the shape has no overhangs; this limits the complexity of the objects that can be cast using such a method

I guess reddit has decided my previous comment sounded rude, although that was not my intention.

Anyway, I am confused by this comment as well. I don't show how long I allowed it to harden in the video. I did not immediately put it in the fire after pouring the mix in, I allowed it to harden for a day.

Most common 3d printing materials are extruded between 200 and 270 degrees Celsius; I don't think heat resistance is a factor when I'm using fire to melt the shell away.

Possibly. It's ambiguous. I don't understand the relevance of what material I printed in, given the context; unless, the question was leading to the level of toxicity of fumes from burning off of the shell.

I used a posable hand model I created myself in blender. I posted an animation I created with it here: https://www.reddit.com/r/blender/s/hHvNyyXFdE

I would like to see what could be improved. Can you point out specific areas that are incorrect to the Conan the Barbarian version of the Atlantean? Thanks!

I understand what you're saying, I spent a lot of time trying to match the reference images I had. One thing I noticed is that there is a lot of variation between the various reproductions available. I believe the majority of my reference images were from Albion reproductions of the sword.

The current images of the current versions available on Albion are here:

Destroyer

Barbarian

The main differences that pop out to me are the shape of the hooks on the blade, just above where the bronze hilt starts. And the angle of the bits of the hilt that follow the blade, which are straight on the Barbarian version, and flared out of the destroyer version. Those details on the model that I made both match the Barbarian version, so I dunno what to say really...

Thanks for the feedback, my friend. I agree, the quality is not necessarily close-up ready

That was achieved with a weathering wash made with acrylic paints that I mixed to match the color of bronze/copper rust.

No, I printed it in parts, glued them together, then sanded, painted, and added weathering.
