Manufacturing process and system for manufacturing a 3d printed drug delivery product

A device for manufacturing a pharmaceutical product, produced by a mixture of an excipient and an active pharmaceutical ingredient (API), the device comprising:

• an extruder device suited to receive a mixture of powder or pellet material in a predefined ratio of the excipient and the API for extruding as an extruded product in a constant output flow;
• a print head comprising one or more nozzles suited for three-dimensional (3D) printing of the pharmaceutical product in a metered fashion from the flow received by a metering pump wherein the metering pump is provided between an outlet of the extruder device and an inlet of the print head, and wherein the metering pump is suited for regulated provision of the extruded product to the print head;
• and
• a distributing member provided between the extruder device and the metering pump, the distributing member comprising:
• an inlet connected to the outlet of the extruder device;
• an outlet directed towards an overflow outlet;
• and
• and an outlet directed towards an input of the metering pump,
• wherein the distributing member is suited for distributing a part of the constant output flow, from the extruder, that is not provided to the print head to a remainder flow directed towards the overflow outlet;
• and for distributing the constant output flow of the extruded product from the extruder to the input of the metering pump.
