Can I buy a 3d printer for my house and if so how much?

@Eric_Moy Raises an excellent point. A larger build volume might be attractive because of the possibility of printing multiple smaller parts simultaneously, but the odds of failure make that a risky proposition. Let’s say you’ve got your printer dialled in sufficiently well that you only get a catastrophic flaw 5% of the time. Also let’s say you want to print a tray of 10 parts. Your odds of getting all 10 to print flawlessly are 0.95^10=59.9% (assuming a catastrophic failure of one will ruin them all - which it usually will). Even if your individual odds of success are 99%, the cumulative odds for 10 parts would mean your odds of success are only 90.4%.

Bottom line - be careful what you wish for.

@Patrick_Ryan If you have a print head with a small-ish footprint, you can print many parts one-at-a-time. I do this often with my Ultimaker.

@Shachar_Weis Sure - but even then, there’s a chance that a failure of one part can cause failures of others.

Yes, now the math gets a bit more tricky. I would calculate the new odds for your 10 part scenario but I wont due to the fact of me being really lazy.

@Shachar_Weis I agree on both counts so we’ll just leave it at that. :slight_smile:
