Quoted from Shredso:SO basically, you guys are saying this is going to get expensive? Ha! Maybe I should reword the question. If I buy the Ender 3 along with a reel or 2 of PLA will I be able to make some simple stuff and learn the machine? I may buy the glass table, that seems like a standard upgrade. I've seen some of the other mods as well but I'm not quite ready to dive head first $500 on something I might not use that much.
Look up Maker's Muse on YouTube, he talks about the machine some. As I recall, it comes with a buildtak style surface on the bed, you might see how well that works for you before installing a glass bed on it.
A couple of reels of PLA should do you to get started with simple stuff and learning the machine. I'd recommend Hatchbox and 3D Solutech filaments. Be careful of the Inland filaments, the quality for me has been a bit uneven; between six spools, one is pretty translucent (yellow) and has a bit of an orange tint, another (green) is bluish and dark and requires a higher temperature and just feels much rougher on the spool for me.
