We demonstrate and characterize a source of Li atoms made from direct metal laser sintered titanium. The source’s outgassing rate is measured to be 5(2) × 10−7 Pa L s−1 at a temperature T = 330 °C, which optimizes the number of atoms loaded into a magneto-optical trap. The source loads ≈107 7Li atoms in the trap in ≈1 s. The loaded source weighs 700 mg and is suitable for a number of deployable sensors based on cold atoms.
