Re: How to enable STL file thumbnails in Windows File Explorer

It depends on how the renderer sets the camera position relative to the XYZ coordinates of your model.

I think I'd prefer third-person to a first-person view anyway. Can't really see much if you look at it from the objects point of view. ;-)

Re: Prestige Optima and Boric Acid

Thanks Sochin for the info. I read online about someone who used 1% by investment weight, but they didn't say if they dissolved it in the water or not. I mixed it with the powder and then mixed it with my water. Everything looked fine for the first 5 minutes, then it started getting a little thick a...

Prestige Optima and Boric Acid

On my last cast, I tried to mix 1% by investment weight boric acid into a 38:100 mixture of Prestige Optima. The room temperature was approximate 64°F, so my investment water was at that temperature. When I mixed it, the working time of the investment is usually 8-9 minutes, but it had dropped such ...

Re: Casting and Curing Tips for Easycast HD

Hard to say. In the past, when I saw brown it was due to incomplete combustion of the resin, like a residue, not necessarily ash, but other byproducts like nitrogen dioxide or something. I cast in my studio and I have burnouts do weird things even though I am using the same program on the kiln, the ...

Re: Casting and Curing Tips for Easycast HD

Where was your print located on the main sprue? Is the burnt side on the outside of the flask or more towards the interior?

Re: Light Intensity

You would need the distance from the bulb to the surface, along with the overall area to do a rough estimate of the mW/cm^2. This can give you an idea of how to calculate it. The projector however uses a reflector, so that alters the calculation since it bounces back some of the indirect light back ...

So what is up with SolusWax Pro?

I received an email from Junction 3D talking about the new SolusWax Pro resin as an improvement over the previous SolusWax, but haven't seen anything on this forum talking about it. I am sure we are all 'burnt out' (pun intended) whenever a new castable resin comes along, but does anyone have anythi...

Like that comment on their burnout chart that all programs were verified using phosphate investment. :o

Re: Circle pendant coming out egg shaped

Is the back of the scarf pin hollowed out? Maybe it is shrinkage of the resin due to the geometry?

I wonder if you print it on its back with elevated supports versus at an angle, would it do the same thing?
