no an ultimaker isn't the way to go.
Way over priced

Printing nylon requires an actual heated build volume - not just a heated bed.
It's one of the most difficult materials to use in an fdm printer. So an actively heated - rather than just enclosed - build volume is a very good idea.
It would also be a good idea to have a high temperature hot-end as it prints at a pretty high temperature.
For many purposes pet-g is almost as good and much easier to work with.

Quality wise, there are many printers around that produce as good a quality as the ultimaker, for a fraction the price.

Kit printers are all well and good - but as you generally need to make some of your own parts, I'd pretty much always recommend them as a second printer.

Start with something like the monoprice or qidi: https://www.amazon.de/QIDI-TECHNOLOG...&keywords=qidi

Then once you've got some experience a kit like the he3d k280 or k200 delta is a very good option for a second machine.
Or - my choice for a more expensive kit - a tevo little monster :-)

You could probably print nylon in the qidi - but might need some extra insulation and heating.

I would always recommend people start with a ready built printer. That way all you are dealing with is learning the art of 3d printing. rather than wondering whether the machine works properly.
Even something as cheap as the monoprice maker select - is a good start. https://www.amazon.de/Monoprice-Prin...oprice+drucker
