I don't see how your final paragraph relates to the passing on of skill. You could equally say, build a printer, build a better one, and pass on the first for someone else to learn with.

@Sean Houlihane that's covered in the paragraph about passing on of skill. If you build the printer with somebody else, you gain the skill together, which is something you cannot necessarily pass on as easily as the hardware itself.

This answer does not actually address what was in the question, where the Nth printer prints the N+1st printer rather than the first printer printing them all. Unless you engineer it out, there **is** generational degredation from any inaccuracies of the previous generation getting reflected in the parts of the next generation in ways that affect its accuracy.

Is there any particular reason why you've hyphenated "itself"? i.e. a stylistic reason, a technical reason, to highlight the reflexive printing aspect,  or to make a grammatical point?

# How many times printed printer can print it-self?

(Asked by: username_0 on 2016-01-12)

There is a 3D desktop printer [RepRap](https://en.wikipedia.org/wiki/RepRap_project) which can print most of its own components.

Assuming each printed printer will print the next one and so on. Are there any limitation how many times this can be achieved?

For example somebody printed for me printer and I do the same for my friends and they do the same for theirs. Can this go forever (since 3D model stays the same), or there are any serious side-effects/disadvantages of doing that continuously?

The files used to print these objects are digital, and do not degrade in any way after each printing. There are no side effects or degradation that occurs over time due simply to printing them multiple times.

This is the RepRap philosophy, and the machines are actually designed with enough tolerance for printing and building mistakes that even if the print isn't perfect, it will not only work fine, but it can print a printer better than it was printed, with some care and attention to calibration.

The process still takes a lot of human intervention, in the way of building the new printer and properly calibrating it.

The reprap printers have often been compared to plants, providing fruits to you and the possibility to reproduce themselves.

This analogy holds in both good and bad ways. Any life form can reproduce itself only so often without artefacts (mutations) being introduced.

It takes a bit of **skill to build, configure and run a reprap printer**. While the parts can be passed on, that doesn't necessarily hold for gained experience.
Chances are that the parts your printer produces are not as good as those that you have received to build the printer. At least not until you caught up on the learning curve.

A reprap has a lot **other parts that are not printed and can vary in quality independently from the printed parts**. It makes a difference what steel rods are used, what driver circuit for the motors, etc. If you give printed parts away that are as good as those that you received yourself, the added parts are not necessarily as good as your.

As long as you maintain each printer and keep a proper calibration, go for it, this is what they were designed to do, I've even made replacement parts for myself.

Unfortunately the [RepRap project just shut down on January 15th 2016](https://en.wikipedia.org/wiki/RepRap_project#History) due to their lack of sales.

I have a reprap that came from a reprap, and has made another reprap.

Just make sure that when printing out the pieces for the next you are properly calibrated, otherwise the next machine might be built crooked;

Your only limitations will be the electronics pieces and the small amount of hardware that you will need to buy.
