Matured nanotech particles controlled by the Central Beiton Server. They were programmed to form almost any real-world objects at the owner's command.
People who paid for the company's subscription plan would own a limited amount of Beitons for their personal use. The levels of subscription dictated the amount of Beiton particles and the complexity of the object they can form. To get a rough idea, middle class citizens usually could afford a Level 1 subscription plan and were able to form any object in the volume of 25,000 cubic centimeter and density of 1,000kg/m^3, or equivalent to a small dog. The complexity of the rendered objects were also limited to a few numbers of materials. Wealthy class citizens would have Level 9-10 subscription plans to form complex objects with exotic materials and have enough Beiton particles to form private jets, luxury cars or yachts.
A new profession emerged from this technology. Any good citizen over the age of 16 could obtain a license from the Server and use a Beiton Design Board to design new objects for the database. Each new design was automatically patterned in the server only the original designer could render. There had been many self-made Beiton Engineers who made a lot of money from selling their novel Beiton products.
True Artificial Intelligence and Machine Self-Awareness
One limitation of the Central Beiton Server was to produce organic objects with true self-aware artificial intelligence. Beiton particles can form life-like objects with a computer mind. They can follow commands easily but have limited independent thinking skills. Many scientists were still developing the first true A.I.
