The first thing that comes to my mind when I hear about 3D printing are very plastic-looking items—often in weird colors—where you can see every “step” from the printer.
That’s what you get with low-resolution filament printers. And before you light-up the comments, I know that you can get better results with better extruders and the “just-right” print settings.
You can also get better results by switching from a filament printer to a resin printer. Instead of working bottom-up by applying layer upon layer of hot plastic, resin printers work top-down by repeatedly dipping into a vat of resin, which bonds to the previous layer wherever it is hit by UV light. That light can be provided by a laser (SLA printers) or a high-resolution LCD screen (DLP printers). Regardless, the result is a significantly higher resolution of model appropriate for jewelry or tabletop gaming miniatures.
Even just a few years ago, resin printers were super expensive. But their cost has come down significantly. I was just a few moments from buying the https://amzn.to/2QhXwfS, which is a (relatively, among 3D printers) affordable $500. Filament printers are infamous for complicated print settings to avoid failed prints and while there’s still some software work with resin printers, the fiddling seems to be significantly less. These printers are a lot closer to “just press print.”
