I successfully took a 3d printed dice and cast it into brass using the lost wax process, very cool and limitless…

How about a how too and step by step

I received the dice from drafting/architecture teacher who has the 2 year old makerbot in his room. I’m not sure what you mean when you use the term “PLA”. I did invest and burn out the plastic. I took the temp up around 1700°.

I only have a small electric burn out kiln and a ventilation system in my kiln room. I was surprised that I did not smell any of the plastic burn nor did I see any smoke. I get more smell from burning out the wax molds.

I can find out on Monday and let you know. I do know the plastic was red.

With only doing one cast so far, I believe it was great. I will be doing more very soon. I am sanding another dice printed from a better plastic.

Picture, picture, picture. Or a thousand words, your choice.

I will put the pictures and words on Monday when I get back to school. :,)

@High_School_Art_Teac Looking forward to seeing them.

If it didn’t smell when burnt I’m almost sure it was PLA. ABS generates very toxic fumes and a strong and nasty smell. PLA is perfect for casting. I’ve seen it before, but the process shown was quite time consuming. It was done with aluminium and a home made propane (I think) burner and oven.
How is it a burn out kiln?
Looking forward more info! It’s great!

I have a student that will be casting 2 “portal companion cubes” on Thursday in brass from the 3D print.
I had him spru on 4 corners. It is probably an overkill, but better safe than sorry. One of the originals was hollow, so he tried filling it in with melted wax. We will see how it goes. I feel that the plastic printables can be added to with wax to enhance or make things better.
I have been using the water displacement method to find volume.
