What’s a good first 3d printer and where can I find the best filiments online
Depends on your budget, experience, and what you hope to accomplish. In the sub-300 range, there are plenty of i3 clones, maybe look at a Wanhao or Monoprice 3D printer. Around $450, consider a Printrbot. Less than a $1000 I would definitely consider an Original Prusa Mk2 i3. In the $2k range, either a printer from Lulzbot or an Ultimaker 2+.
