Unfortunately 3D printers don't print clear acrylic blue tinted material at the moment. Which is why if you want your 3D printed Blue meth throne to look like "Blue Meth" you need to create a silicone mold and perhaps a hard shell mold.



The reason we are using the hard shell technique in this project is because our Blue Meth Throne is relatively large for us to use a 2 part Silicone mold. Doing such technique would waste too much material and will double or triple the price of the mold. This method is a bit more work but if done right very useful and efficient.











We made a 3 part hard shell mold at the beginning but didn't account for the small indentation in the chair part which made the mold almost impossible to take out. We created another 4 piece hard shell mold to fix this problem which made it much easier to take off.



Anyways



We used smooth-on supplies for our mold because they are the closest to us and seem to work rather well. We used about 3 coats of brushable silicone material and the hard shell also brushable material. We also used an special clay to restrict the flow of the material which doesn't react with the silicone or the hard shell material.



We speed up the process on this one a lot! this whole thing took us a couple of days but cramp it down to 10 minutes.



The Gist of of it is that you want to first adhere your 3D Print to a very smooth surface that will hold your mold but won't stick to your silicone or your hard shell. I used a piece of glass and adhere my 3d mold using some clay.



Once your model is secured you can start brushing on about 3 coats of silicone. Use some kind of tint to differentiate between coats so you make sure you get multiple coats evently. i try to brush on my silicone once the previous coat is almost done drying.. while still a bit sticky but hard enough so it won't come off the mold



Once your outer coat of silicone is done i used clay to separate the area where the 1st hard shell area will be going.. The hard shell material starts a bit watery but as it thickens it's easier to keep on the top areas. You might have to keep pushing it up till it thickens. You also want to create a lip area where the 1st shell will meet the 2nd and 3rd part of the hard shell. As you can see at the bottom i created a barrier to keep the material from falling out of certain area. Doing this minimizes the mess.. i do two coats of hard shell per area i found that one coat is too brittle. Once done with part 1 of the mold remove part of the clay and begin part two and do the same process till you get to part 3.



You could leave your mold the way it is but doing so will require a lot more material.. So i rotated the mold upside down and created a bottom mold are.. Doing So will make somewhat of a hallow mold which will require a lot less material and keep the throne less heavy. My plan is to add some LEDs inside of it in the future so that's why i like this throne somewhat hollow.



The bottom mold has this small clay legs that are later removed and later became air vents to let air and prevent air bubbles. The middle part of the throne where the charger goes will be the primary area where the liquid plastic will be poured.
