The printer is an Ender 3 Pro. https://www.amazon.com/gp/product/B07K3SZBHJ/

This is a budget printer that takes a bit of tweaking to get really good performance out of, but it's definitely doable (and relatively easy). There are a few pieces that need replaced out of the box:

The extruder with it should be replaced with a metal one: https://www.amazon.com/gp/product/B07B96QMN2/

The springs that level the bed need to be upgraded: https://www.amazon.com/gp/product/B07FY47BX7/

The printer comes with a bed that has a removable magnetic cover. They're quite nice to use, but suffer if you abuse them (stretching in parts, or tearing). I suggest not using it, and just going with the tempered glass. Lots of people use the magnetic bed with no trouble at all, though, and mine lasted several months before I replaced it. It's a preference thing. But if you want the glass bed, here's the link: https://www.amazon.com/gp/product/B07FSM8DK9/

Some parts are consumable. You're going to want to have extra nozzles, bowden tube, and bowden tube fittings on hand.

Now your software is free. 3d printing works by taking a model (an STL file) and slicing it to generate gcode which is the instructions you run on the printer. To do this, you need a slicer. The one most people use is called Cura, it's free and downloadable here: https://ultimaker.com/en/products/ultimaker-cura-software

All in, the printer and all the suggested upgrades should be right around $300.
