For my delta 3D printer I got this power supply [www.soaap.com] , but I'm wondering if a 3D printer can work with just 1 amp.

That would just about power the controller and nothing more. The extruder alone is going to pull about 6amp while it warms up.

You need to power four motors at about 1A each, the controller board- maybe about 1A, the bed heater (?)- about 10-20A depending on the machine, and the hot-end about 3-4A. That all adds up to 18-28A, mostly depending on the bed heater current.

A 1A supply isn't going to do the job.

Actually I'm not using a heated bed (by a miscalculation on how much money I could spend on the 3d printer), but thanks!

Even if you don't have the money now, spending slightly more on a more powerful electronics could save you in the end if/when you do get a heated bed.
