Abstract: A heating and cooking apparatus inside the cooking chamber of a 3D food printer includes a laser cooking apparatus controlled by a processor implementing particular computer program instructions specific to the operation of the heating and cooking apparatus. The laser cooking apparatus includes at least one laser system with at least one laser beam able to heat the food product to its cooking temperature. Each laser system provides two or more laser beams, each of which can be deflected and focused into the food product with a beam spot of adjustable diameter. The heating and cooking apparatus also can include an electromagnetic radiation heating apparatus that is controlled by the processor and emits electromagnetic radiation to warm the food product inside the cooking chamber to a temperature below its cooking temperature.

Abstract: A 3D printer system that uses the AM method to print a product using a plurality of materials, each of which is contained in a respective capsule. The capsules are removably inserted into respective capsule holders, each of which includes a heating device for adjusting the temperature of the material, and is releasably held in one of a plurality of stations. A tool fetches individual capsules from and deposits them to their stations, and holds individual capsules for printing the product using a telescopic extrusion apparatus. A memory stores capsule-identifying data, a processor provides position coordinates for positioning of the tool, and a controller moves the tool to the position coordinates. The capsule holders include heating systems for controlling the rheological behavior of the materials based on algorithms executed by the processor.
