Best Resin 3D Printers in 2021

Oct 30, 2021
Prices are incorrect and in my opinion there are much better options out there.
This would be my list.

Best Overall
Epax X1-4k
4K mono screen. They're built like a tank. The X1 platform is upgradable.
Company headquarters are in the USA (much easier to get parts & support should you need either)

Best High End
Formlabs Form 2 (I prefer it to the form 3)

Best Large Format (there are a lot of good machines in the category)
Uniz Ibee + Lychee Slicer
Exceptional build quality & a superior light source to most other printers in it's class
Can be found new for $400-$500. (frequent promotions) Retails for $1400

Best High Resolution Machine
If high resolution is what you're after hold off for now. New tech is just around the corner. Watch for these machines.
Phrozen Sonic Mini 8k - 8k LCD machine, build quality looks to be much improved over last years 4k model.
Anycubic Photon Ultra - DLP based machine. Actual resolution is quite low but the quality of the DLP light source is supposed to be a game changer.
Mars 3 DLP - Another DLP based machine to look out for. I understand the resolution of this machine will be superior to the Photon Ultra

Best $300 or Less
Elegoo Mars 3
Least expensive 4K mono machine. Seems to outperform the Phrozen Sonic Mini 4K.

I've considered getting one of these, but I'm wondering - how do you deal with the smell? As I understand it, the resin requires good ventilation, but I live in a small apartment with a couple windows on one side and a hot climate. I can't imagine having to deal with fumes for hours while something is printing.

An apartment isn't the ideal environment for a resin printer. The smell isnt really what you need to worry about, there are a lot of resins that don't have a strong or unpleasant scent. Dangerous VOC's are the concern & the smell from these fumes may not be noticable. I know at least one resin manuacturer (sirayatech) says that the amount of VOC's released from uncured resin is quite low but VOC's will likely build up inside the printer. You're most likely to be exposed when you lift the lid after completing a print. If you have a window in the apartment you could make some modification to continually vent the fumes, or you could have a fan or something to exhaust them when you're most likely to be exposed. I'd invest in a vat cover to keep the VOC's from entering your living space while the printer isn't in use.
