The 3D Printer visibly cycles through different weapons when idling, and upon purchase, a random weapon will then be displayed. Despite popular beliefs, the player cannot time the printer to get a weapon that is displayed while the Printer cycles through them.
The 3D Printer, if used enough times, will eventually malfunction, and another 3D Printer in another location will be activated, similarly to the Teddy Bear effect for the Mystery Box. It costs 1,000 points to be used, as opposed to the Mystery Boxes 950 points. During a Power Surge, all 3D Printers will be made active and they will all only cost 10 points, similarly to the Fire Sale.
If the player upgrades a weapon, replaces it by purchasing a different weapon, and then receives the weapon (that was replaced) again from the 3D Printer, it will retain its upgrades. This can be useful in the later rounds, as some weapons will run out of ammo easily, and getting it from the 3D Printer, although risky, will give the weapon back with all ammunition.
