SLS, the sintering technology used by Shapeways for their strong and flexible and detail plastics, requires huge machines and wastes a hugton of material if the print space isn't full of models. So it only works financially for them because they can print your model along with a hundred other models from other people in a go. Resin / SLA and FDM printers generally print one model at a time and don't have an economy-of-scale effect in the same way. But resin / SLA requires toxic chemicals that go bad over time and have to be handled carefully. It really just leaves FDM.
FDM can be done with PLA or ABS, but ABS smells godawful during the printing process, so it's really only practical to have PLA as an option in a public MakerSpace.
