I could be completely off base with all of this, but some of your statements are concerning. From your question: 

> from previous experience I know that their quality of work is much
> lower than mine, I decided to do it myself

And one of your comments:

> In order for my group members to produce the same quality I expect
> from me I would have to spend hours teaching them and also would need
> to motivate them immensely to keep working.

Have you considered that maybe you're the problem? It's a self-fulfilling prophecy. You believe your teammates to be incompetent, therefore they are. It's not easy, but you _have_ to learn to trust people to do their work.

Back to the first quote: "_I decided to do it myself._"

It sounds like you took it upon yourself to start the work and do it all, and now you're upset that they didn't contribute. That's not fair. You never even gave them the chance.

So should you tell your lecturer all this? From this point of view, no. Your team didn't pull their weight, but it sounds like you didn't give them the chance. You have no right to be upset about it.

Take this one on the chin, and for the next project schedule a mandatory team meeting. In that meeting, figure out the project requirements, break them down into pieces each team member can do, then assign everyone work _with a deadline before the project due date._ If they don't pull their weight here, then you'll have a legitimate complaint.
