Is making LEGO pieces from sand casting possible?

Question

Is there anyone out there who make their own LEGO pieces? If it is possible, how do i make the mold? I was thinking of using candle wax as the mold and use Wood's metal as the LEGO piece. Would it cause some damage to the LEGO piece?

Answer 1

I do not think that you can work precise enough to get working pieces.
If you want to have Lego cheaper than the store prices, buy second hand. (Yard sales, car-boot sales or flee markets are a good hunting ground, as well as the websites that circulate free or cheap secondhand goods.)

If you want your Lego to have special colours, try it, but be willing to risk a few pieces in making molds. First make a few and see if they work before spending a lot on them.

Answer 2

No. Not without being able to control the weather. Like all deserts, the Sahara was formed due to a lack of water from rain. Like all deserts, it could be irrigated to turn it into productive farmland. But turning on the rain is something that we are still a long way from managing. And if we force rain onto two million square miles of desert, we're going to be massively changing the climate somewhere else, hopefully the middle of the Indian or Pacific oceans. Terraforming refers to the changing of an entire planet, not just a small area, to turn it into a new Earth (Terra). Mars may be Terraformable since it is almost warm enough, has lots of water, and enough atmosphere to get the process going. Venus would likely require completely different methods and due to it's closeness to the Sun, might be beyond our capabilities for another 500-1000 years. How long it would take to terraform any planet would depend on a set of factors unique to each planet. The biggest in every case, whether forcing rain onto the Sahara or turning Venus into Las Vegas or Miami, is going to be money, willpower, and environmentalists that want Mars and Venus to stay just as they are, useless.
