The invention relates to a method and a production line for making tangible products by layerwise manufacturing. The production line comprises (i) a first and a second building platform (102, 12) for carrying a tangible product, (ii) a deposition head (101) for providing a layer of construction material onto the building platforms, (iii) a conveyor (103) for conveying the building platforms in a conveying plane towards and away from the deposition head repeatedly, (iv) height adjustment means (107) to adjust the distance between the deposition head and the building platforms by displacing the building platforms relative to the conveyor in a direction (104) perpendicular to the conveying plane. The production line may further comprise a picking unit (106) for picking a product from the building platforms. The method allows making different tangible products in a continuous process by layerwise manufacturing. The method comprises a step of moving the platforms on which a product is made repeatedly past a material providing device for depositing subsequent layers and a step of adjusting the distance between such device and the building platforms by moving the platforms in a vertical direction.
