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.
My recommendation would be that you and your friends get printer parts from that somebody and you build your printers together. While giving parts to others is a great thing, building 3D printers together with friends is greater.
