A first printer is easier to choose when you answer a few questions before looking at models: what is the largest object you want to print, where will the printer sit, will anyone be bothered by noise, and do you actually need more than one colour in a single print.
Read the five-question first-printer checklist first, then the build volume guide to confirm what must fit on the plate and on the desk. If you share a room with the printer, read the noise guide next. Leave the multicolour decision until last, because it adds cost and space that only pays off if you will print in several colours regularly.
Once you have narrowed the field, the brand-specific beginner guide and the comparison pages help you choose between the remaining models.
