This is the thread for my current project Dewy. He is a tall robot that uses RAD parts and models a omnibot in a way....
step one, make a box or edge barrier for your box. Use something disposable and easy to remove once the silicon sets.
step two, work slowly adding clay around the perimeter pushing it into corners and packing it down.
step three, continue adding bits of clay to make a level bed to work with
gently press in the first part and push the clay up against the edge of the part
press in the second part and add registry marks for perfect alignment between the two halves of the mold.
gently take a sharp tool and go around the parts edge to make a clean edge.
the parts are very thin and bubbles likely cannot rise to the top. I do not have a vacuum chamber on hand so this mold will need a large air vent. In addition I have syringes to gently force the resin down into the mold
I used alumilite silicone rubber that cures in around 12-18 hours fully. This represents a 2 ounce liquid pour. I may make the other half thicker around 3-4 ounces for dimensional stability.
Hello all, I am up later tonight and took some time to cast some BB8 Hero droid antennas.injection molding at home with two part resinoid. Pot life 2 minutes, Demold in 5 -10 minutes
Parts cut out, I will leave these alone until morning, they will still be soft for a while because they do not heat up to full temp when they are so thin. If this was a larger chunk it would be a rock already like the left overs in the bottom of the plastic container
Copies next morning after flashing has been trimmedThe replacements get a bit of black paint
I used to do a lot of casting for modeling work so I really appreciate your efforts. It can be a science and an art. Maybe subliminal but I really want sushi now.
I seen this one time thought maybe some day I'd give it a try. Looks like a cheap way of doing some small molds. Can you say hijacking a thread ... lol.
