Abstract: A scalable and rechargeable system is disclosed that recycles and repurposes a very wide range of meltable waste and/or other meltable materials, and can re-use the recycled meltable material within the system for an additive process and/or subtractive process to make 3D objects. The recycled material may be ground into homogenous and/or heterogenous grains, filaments, powders, and/or shards, which can be stored or used as feed for 3D printing, CNC machining, and/or injection molding. An embedded interface, software, and/or file management system, coupled with Wi-Fi, USB, and/or Bluetooth technologies, control the motorized machine, its machine head system, and/or reversible and lockable building deck, with storable, adjustable, embedded, and/or locking clamps, which may be configured for 3D printing, injection molding, and/or CNC machining within the same system, powered by renewable and/or non-renewable energy sources.
