IMO there are two things to consider. First: do you want FDM or SLA. You’re trading resolution for build volume. If you’re going to be making a lot of smaller things, SLA printers can offer more output since they print the same speed no matter how much of the build plate is occupied. Also consider the size of the things you’ll print. In other words, how much build volume should you be looking for.
Second: are you seeking to tinker with the printer as a point of interest/engagement or are you simply looking for the printer to be a tool?
Off-the cuff list:
- enders are cheap, but will likely result in you wanting to fiddle with the printer
- Sovol are a bit more expensive, but should require less fiddling
- Prusas have the reputation for set it up and forget it workhorses and are priced accordingly
- Voron printers are 100% open source and there is no “official” storefront or kit. Plenty of companies offer a “BOM in a box” option. You’ll build a printer from parts and it’s a very solid base to just print with or to fiddle with. If you dig through my post history you’ll see quite a few posts and comments about mine. Sourcing a Voron can be pricey though
… There are tons of other options too
On the envelope side: printing is more forgiving of having too small an envelope than machining. Since printing is all about adding material you can usually split the thing you want to print into pieces. I still think it’s worth considering it the usual 200mm^3 will be enough since splitting parts can be annoying.
Harbor freight is a good comparison to an ender. They’re fit for purpose, have some cheap parts, and are a decent platform to modify from. They will work out of the box most of the time, but you’ll find yourself wanting to improve them.
Printer bones are very replaceable, especially if you have a functioning printer. I printed my Voron parts on my old i3 clone. I’ve now used my Voron to print future parts for itself before tearing some of it down and modifying things. People do the same with enders. There’s even an Ender variant that rebuilds the Ender with a lot of Voron design ideas.
The only thing to be aware of is ultimate cost. Yes, you can turn the ender into most anything over time. It could wind up costing more money and time doing this though. Ultimately, the decision on how far to take the modifications will be yours and you can choose whether or not you want to have a frankenprinter. You’ll also learn a lot along the way going this route, which takes me back to my original question: what are your goals for this project?
