I'm interested in buying the cheapest possible 3D printer that is user-friendly. That is, I don't want to have to do any assembly or trouble-shooting. If possible I just want to set it up, download the design, and click print, without having to know technical details.
Here are the three cheapest 3D printers I've found:
The da Vinci Nano, which is $230.
The Monoprice Select Mini, which is $199.
Reprap, which is an open-source self-replicating 3D printer, and which is in a variety of models and prices, the cheapest usually being in the $150-$165 range.
Of the three, I think Reprap is probably the least user friendly; it involves a kit that you have to assemble.
Which product is recommended for me? I'm looking for one that is safe, and preferably one that works with an iPhone instead of requiring me to use a computer.
