A 3D printing apparatus comprises a housing 202, a movable seal 204 – or piston - partitions the housing into first 206A and second 206B fluidically isolated chambers, and a nozzle 208 in fluid connection with the second chamber. The first chamber comprises a gas having a pressure P1 and the second chamber comprises a printing material 210 (eg. a liquid photopolymer). When the 3D printing apparatus is exposed to an external environment having a pressure P2 less than the pressure P1, the pressure difference exerts a force on the seal thereby extruding the printing material through the nozzle. The nozzle preferably comprises a temperature control module 218 and a curing device such as an ultra-violet light source 220; the pressure P1 may be less than 1atm such that the apparatus may operate at pressures lower than atmospheric pressure, such as in outer space. A system for positioning a satellite component – such as a folded solar panel, or a stowed antenna - comprising the 3d printing apparatus arranged to print an elongate structure to move a printing platform 212 away from an attachment point on the apparatus to deploy the satellite component such as by unfolding or unrolling of the component. A method of operating the apparatus is further provided.
