With a sample of organic Protyon Units it is even possible to clone a whole new TARDIS using a fist sized piece of a pre-existing female Capsule. Indeed, even if a TARDIS suffers enough damage to reduce it to a 1 inch cube the molecular stabilizers will still be able to re-grow the capsule.
In either case, the regeneration occurs in much the same way that the capsule originally grew in its Dimensionally Transcendental Cradle. The capsule's Protyon Units will use warp matrix engineering to reform in endo and exo shells following the specifications set down in its Grey- Prints. This process will start with the Cloister Room and expand from there to reform the rest of the Time Sceptre.
With a Dimensionally Transcendental Cradle to feed it this re-growth will only take a decade. Without it, the new TARDIS have to rely on some other source of artron energy, such as that generated by being close to a Time Lord. When limited in this way the TARDIS will take thousands of years grow up. The growth of the exo-shell will be limited to about 4 cubic inches per year. Once the capsule's exo-shell has reached a size of about 2 cubic metres it will take about 90 years for its shell for its materialization beacon and to become active. The surface of the shell will also hum when touched by a Time Lord. Approximately 20 years after that point the regeneration mode will be completed and the TARDIS will allow the Time Lord entry.
At the end of this time the TARDIS will still need to have several pieces of exitonic circuitry implanted in it. These systems include the chameleon circuit, the gender circuits, and, most importantly, the temporal drive. Given the about of time the cloning process will take, an experienced Time Lord with the proper plans, will have plenty of time to build the necessary systems; even if they are limited to primitive Level 5 technology (such as that found on Earth in the late 20th century). In the case of re-growing a catastrophically damaged TARDIS it is possible that some or all of these components might have survived and the TARDIS will be fully functional.
One way to accelerate this growth would be to find a source of energized morphologically unstable organic material. Depending on the power levels, this could reduce the grow time to around a century. Similar results can be obtained by shatterfying the plasmic shell and modifying the dimensional stabilizers to a fold back harmonic of 36.3. This will accelerate its growth by a factor of 59. Continual exposure to Rift Energy can also help reduce the growth time to about 50 years.
It is not unknown for time aware species to attempt to illegally clone a TARDIS using this process. A fully cloned TARDIS (legal or otherwise) is usually designated with a Model number based on the Type of the capsule that provided the cutting. Hence the clone of a Type 60 would be know as a Model 60. It should be noted that an illegally cloned TARDIS would have the same Imprimature Signature as original donor TARDIS. Which means that the official owner of the parent TARDIS can be easily found by cross-referencing the TARDIS's Imprimature Signature against records on Gallifrey.
While some humans have been able to acquire Model 70 clones from Nekkistani on the world of Gryben, the most notorious examples of TARDIS duplication was Magnus the War Chief's construction of several TT Capsules for the War Lords. Though the Capsules were probably cloned from the War Chief's Type 42 (or 43) Capsule, his ally the Master failed to provide Magnus with all of the pieces of exitonic circuitry that would be necessary to create full operational Model 42 TARDIS clones. Most notably the timeships lacked the green crystal dynamorphic projectors. Since the crystals are only found on Gallifrey, other, less sophisticated materials had to be used, resulting in a capsule that was much more prone to breakdown. There were also no Chameleon Circuits installed on the ships.
These simplified TT Capsules were known as Space and Inter-Time Dimensional Robot All-purpose Transports, or SIDRATs. While capable of travelling over half a million years their range was more limited than the standard TARDIS. Their simplified design did give them a great deal of dimensional flexibility, allowing their internal architecture to be easily reshaped and they could hold thousands of passengers. As their name implies, these 'robotic' transports were designed to be remotely controlled. However, as with most forms of remote control, this drastically shortened the life of the time control units which are part of the dynomorphic projectors. Under continual use they rarely lasted more then a few weeks.
