Tech Lab

The Tech Lab is the Building which is unlocked once you have defeated the Uranium Elder and moved onto floor 96 is used to beam down liquid nitrogen to freeze the blocks below, the blocks on this floor are extremely hot and nearly liquid they are so odd that you cannot fire any laser without miracle gas which also does not do much damage. The Tech Lab is therefore used to advance yourself to the obsidian elder and used to defeat him, you position the tech lab a floor above where you are firing and use it to make it possible to destroy the lava-like blocks below.

It also allows you to use dry ice (a crafting recipe) to force rainfall to begin, but the ruinous cost of dry ice means that you will never, ever want to do this.

Finally, it allows you to spend honor badges from guild events to boost smelting, crafting, chemistry, or mining. Each boost doubles your speed (cuts time taken to do things in half) for a period of time, which is 6 hours for the first three, and 3 hours for mining.
