3D Printers

''This article is a stub. You can help by expanding it.''

The 3-D Printer is a new mechanic in Risk of Rain that allows players to have a little more control over what build they want and what items they desire, but not to the extent of the "Command" artifact. The 3-D printer will appear as a large blue box with one half open and an item sitting on the other side as a display of what item you will receive when interacting with it. It should be noted that money is not used to 3-D print. Whatever item is being displayed, a random item of similar rarity will be taken out in trade for the new item instead.

For example, if a Soldier's Syringe is on display, a random item of White Rarity will be removed from your inventory and will be replaced with a Soldier's Syringe drop. The 3-D printer can be interacted with for as many items of the rarity as you have. So, in the previous example, if you have seven items of White Rarity, not including the item on display, you can use the 3-D printer seven times for seven syringes.

Using the 3-D printer seven times will grant the "...maybe one more" achievement and will unlock the "Fireworks" item. However, while it is possible to use the 3-D printer with the same item over and over, such as turning syringes into syringes, it will NOT count for the seven duplication needed.

3-D printers will often have common items on display. However, you can find 3-D printers for uncommon, and even legendary items. It is generally thought that this occurs in much later rounds of a game.
