A production line for making tangible products by layerwise manufacturing. The production line comprises: (i) a first and a second building platform for carrying a tangible product; (ii) a deposition head for providing a layer of construction material onto the building platforms; (iii) a conveyor for conveying the building platforms in a conveying plane towards and away from the deposition head repeatedly; and (iv) height adjustment means to adjust the distance between the deposition head and the building platforms by displacing the building platforms relative to the conveyor in a direction perpendicular to the conveying plane. The production line may further comprise a picking unit for picking a product from the building platforms.

Production line for making tangible products by layerwise manufacturing

A production line for making tangible products by layerwise manufacturing. The production line includes: first and second movable carriers, each carrier comprising a transporter for transporting the carrier, and a building platform for supporting a tangible product, one or more deposition heads for depositing construction material in a deposition direction onto the building platforms, and a conveyor for conveying the first and second building platform towards the deposition head and away from the deposition head repeatedly. The first and the second transporter are movable at variable speeds relative to each other along a trajectory of the conveyor. Optionally, the height of the building platforms can be adjusted.

The invention relates to a production line and a method for making tangible products by layerwise manufacturing. The production line comprises a deposition head for depositing construction material layerwise on a building platform. The building platforms can move with a different speed along a conveyor. Optionally, the height of the building platforms can be adjusted. The method is characterized in that at least two building platforms are moving with different speed.

Apparatus and method for making tangible products by layerwise manufacturing

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 () for carrying a tangible product, (ii) a deposition head () for providing a layer of construction material onto the building platforms, (iii) a conveyor () for conveying the building platforms in a conveying plane towards and away from the deposition head repeatedly, (iv) height adjustment means () to adjust the distance between the deposition head and the building platforms by displacing the building platforms relative to the conveyor in a direction () perpendicular to the conveying plane. The production line may further comprise a picking unit () 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.
