In Star Trek a replicator is a machine capable of creating (and recycling) objects. Replicators were originally seen used to synthesize meals on demand, but in later series they took on many other uses.

Origins and limitations

The term "replicator" originated on Star Trek: The Next Generation, portrayed as a 24th century advancement from the 23rd century "food synthesizer" seen in Star Trek: The Original Series. The mechanics of these devices were never clearly explained on that show, but the subsequent prequel series, Star Trek: Enterprise, featured a 22nd century version referred to as a "protein resequencer." Additionally, that ship had a "bio-matter resequencer" which was used to recycle waste product into usable material.[1]

A replicator can create any inanimate matter, as long as the desired molecular structure is on file, but it cannot create antimatter, dilithium, latinum, or a living organism of any kind; in the case of living organisms, non-canon works such as the Star Trek: the Next Generation Technical Manual state that, though the replicators use a form of transporter technology, it's at such a low resolution that creating living tissue is a physical impossibility.

In its theory it seems to work similarly to a universal assembler.

Theory

A replicator works by rearranging subatomic particles, which are abundant everywhere in the universe, to form molecules and arrange those molecules to form the object. For example, to create a pork chop, the replicator would first form atoms of carbon, hydrogen, nitrogen, etc., then arrange them into amino acids, proteins, and cells, and assemble the particles into the form of a pork chop.

This process requires the destructive conversion of bulk matter into energy and its subsequent reformation into a pre-scanned matter pattern. In principle, this is similar to the transporter, but on a smaller scale. However, unlike transporters, which duplicate matter at the quantum level, replicators must be capable of a large number of different materials on demand. If patterns were to be stored at the quantum level, an impossible amount of data storage (or a set of original copies of the materials) would be required. To resolve this, patterns are stored in memory at the molecular level.

The drawback of doing so is that it is impossible to replicate objects with complicated quantum structures, such as living beings, dilithium, gold, or latinum. (However, in the TNG episode "Allegiance", aliens used their version of replicators to create a Picard impostor.) Additionally, read/write errors cause a number of single-bit errors to occur in replicated materials. Though usually undetectable to human senses, computer scanning can be used to reveal these discrepancies, and they may explain the frequent complaint (by some gourmets and connoisseurs) that replicated food and beverages suffer from substandard taste. These errors also may cause a nontoxic material to become toxic when replicated, or create strains of deadly viruses and bacteria from previously harmless ones.

Uses

One of the most important pieces of technology in the Star Trek universe, the replicator is used primarily to provide food and water onboard starships, thus eliminating the need to stock most provisions. (Starships, starbases, and other installations stock some provisions for emergency use, in case of replicator failure or an energy crisis.) On Star Trek: Deep Space Nine, it was established that replication is also used to provide breathable air on ships and starbases (and to disassemble the carbon dioxide exhaled by the crew), thus providing an endless supply of oxygen and eliminating the need to carry air tanks.

The technology is also used for producing spare parts, which makes it possible to repair most ship damage without having to return to a starbase. Other applications include replication of Starfleet uniforms, as well as everyday objects such as toys and souvenirs. Replication is also used by the Holodeck program to allow food, clothes and other objects belonging within a simulation to be used or consumed by the participants.

Starfleet's safety protocols prevent unauthorized replication of dangerous objects, such as weapons and poisonous substances. Replication of any medicine is restricted to medical personnel bearing a valid identification code.[2]

Replicators can also convert matter into energy. Following that principle, the device can dismantle any object into subatomic particles. The ensuing energy can then be stored for future use or immediately applied in a subsequent replication. This process is referred to as "recycling", and is applied to everything from dirty dishes to outgrown children's clothes.

Replicator technology, even if produced on a larger scale, cannot be used to create complex objects such as shuttlecraft or starships (production staff felt that being able to replicate entire starships "at the push of a button" would severely impact dramatic potential). However, in Star Trek: Deep Space Nine, industrial replicators are used to replicate large components of ships, shuttlecraft, and other pieces of this sort, which are later used in shipyards to construct such vessels. In this manner, as few as 15 industrial replicators are enough to replicate the components needed to build a fleet of starships or to help a civilization recover from a planet-wide natural disaster.

By virtually eliminating material scarcity, replicator technology plays an important role in the moneyless human economy within the Star Trek universe.

Voyager

When the USS Voyager was pulled to the Delta Quadrant, it became clear that replicator technology was unknown to the indigenous peoples of that region. Throughout the first seasons, the Kazon and other races tried repeatedly to obtain the technology. Captain Janeway feared that if this technology were acquired by a civilization before they were ready, disastrous consequences could ensue (on one occasion a Kazon ship was severely damaged when its crew tried to construct a replicator; instead the deck was flooded with nucleon radiation and extremely high levels of Neosorin particles). For this reason, and because of the Prime Directive, Janeway refused to give away the technology at any price.

Also on Voyager, the ship's energy constraints on the journey back to the Alpha Quadrant meant that replicator supplies had to be strictly controlled, leading to "replicator rations" becoming an unofficial ship currency. This is also the reason Neelix (aside from providing the crew with a morale boost through the preparation of fresh food) became employed as the ship's chef. Some ingredients came from the ship's hydroponics laboratory.
