Purchasing a first 3D printer
This is going to depend on your particular wants and needs.
Initial buy price is a big factor, obviously, but there are some other things to bear in mind:
What are you going to use it for?
If you're going to use it for printing, say, RPG miniatures, you might want to focus on SLA/DLP (resin) printer because they can produce very good detail at small sizes. But entry level SLA/DLP printers tend to have very small print areas.
FDM (filament) printers tend to have larger print areas but they don't tend to be quite as accurate when it comes to reproducing small detail. They have more material choices available to them, though: PLA, ABS, and PETG are sort of the basic three materials that an entry level printer can probably handle.
How much of a &quot;tinkerer&quot; are you?
Some printers are &quot;open source&quot; which means you are able to modify their firmware and/or hardware. For example, you might be able to upgrade the firmware and hot end of an FDM printer to allow you to print more exotic materials like nylon and PEEK.
That ability to tinker and modify your printer is great if that's the kind of thing you value. But it also means you might have to rely less on the manufacturer and more on the community if something goes wrong or you're unsure how to go about doing something with the printer.
How much are you going to use it? / How much room do you have?
The cheapest printer in the world is still too expensive if you never use it. Plus, it takes up space. This is something you really have to keep in mind: printers need space. Even if the printer itself is small, you might need to buy an enclosure for it.
You probably need a workspace nearby to finish your printed parts. I think resin printers need a space to setup a UV curing lamp to fully cure the resin of the printed parts, for example. If you print more than one type of material with an FDM printer, you need a place to store those extra spools of material.
