A method and a device for the production of an optical element (100) from a curable material by using an additive manufacturing technology. This method comprises a multiplicity of curing steps for curing said curable material inside outlines (C1) whose geometry are determined according to the geometry of said optical element, by applying a curing surface energy onto the curable material that is higher in a first area (A1) that extends sensibly along said sliced outline than in a second area (A2) situated within the first area, the curing surface energy applied to the second area being strictly lower than a first predetermined energy threshold.

The invention provides a solid-dosage-form printing apparatus comprising: i) a 3D printer suitable for printing solid-dosage-forms, said 3D printer comprising an interchangeable print head selected from the group consisting of: a fused deposition modelling print head, a semi-solid extrusion print head and a direct powder extrusion print head; ii) a build platform; iii) a balance for measuring the mass of the printed solid-dosage-forms, said balance being integrated into said build platform; and optionally iv) means for performing in-line near-infra-red and/or raman spectroscopy on the solid-dosage-form product; wherein said solid-dosage-form comprises at least one active-ingredient and at least one excipient. Further provided are methods of producing solid-dosage-forms using the apparatus, including computer-implemented methods.

The devices and systems described herein generally relate to magnetic field chambers and reversibly hardenable ferrofluids. The reversibly hardenable ferrofluid can include a magnetically responsive fluid and a reversible hardening agent. The reversibly hardenable ferrofluid can achieve a first shape using one or more magnetic fields, such as delivered from a magnetic field chamber. Once the first shape is achieved, the reversibly hardenable ferrofluid can be cured or otherwise hardened. The hardened reversibly hardenable ferrofluid can be used for the intended purpose and then returned to a liquid state once the task is completed, allowing for reuse. The steps of hardening and liquifying can be mediated by the magnetic field chamber, as described in embodiments herein.

A vehicle comprises a chassis, wheels rotationally mounted to the chassis, each wheel being disposed within a respective wheel well, and a tire mounted to each wheel. A tire sensor disposed within the wheel well senses a tire condition and generates and outputs a tire condition signal indicative of the tire condition. A repair controller receives the tire condition signal from the tire sensor and processes the tire condition signal to determine whether to repair the tire. The repair controller is configured to generate and output a tire repair signal. A 3D printing device disposed in the wheel well and communicatively connected to the repair controller receives the tire repair signal and 3D prints an additive reparation to the tire by drawing a tire repair compound from a supply container within the vehicle and by depositing the tire repair compound on the tire to repair the tire.
