ELEGOO Mars UV Photocuring LCD 3D Printer $210

If you don't need it right away the Saturn model launched like a month ago. They are out of stock last I checked but you get a much larger build area and stronger UV source for faster printing. One of the likely reasons this is on sale. If you are just getting into resin printing one of the key requirements of print cleaning is alcohol which has been impossible to get or to get cheaply, anywhere since COVID. Which is another reason to hold off.

good point on the alcohol- but looks like the Saturn is in a different price bracket unless I'm missing something?

The chemicals kinda threw me off on resin printing. Isn't there waste that's bad stuff?

Most of the focus I've read is you really don't want to be doing it in an area that isn't well ventilated. The fumes while not deadly are not good long term at all. I want to try out resin printing, but I need to get some sort of ventilation in place first. Before covid hit and made plexigass a hot commodity

Since I would have to do it in the basement which can't easily be well ventilated I was looking into basically building my own large fume hood to hold a resin printer and my FDM printer for printing things other than PLA. A mix of procrastination and unsure about how much I would use it have also delayed the project.


The only actual waste I can think of would be resin that has gone bad and is no longer usable. For that the solution is literally to just leave it in the sun for a while and let it cure and dispose of after that (if the cured resin was a problem then the things you print would be toxic too).




As a note for the other conversation about saturn vs. ELEGOO Mars vs ELEGOO Mars pro I personally am planning to buy the Pro because I think the additional features are worth it for the time and ease of use savings. The Saturn prints much larger prints, but unless you are actually printing that large it adds complexity, the amount of toxic uncured resin you have to deal with, the waste if you don't use it frequently etc.


For my FDM I got one with a 1 foot build plate (Creality CR10S) and I have mostly regretted it since I rarely use the whole build plate and it makes printing small things much harder.

Good info. I am hesitant to get a resin printer as well because of the venting situation. I do not have an extra room in the house that I can isolate the printer (and the fumes) in. As far as toxic waste, I worry about all the alcohol required to wash the just printed parts to remove excess resin. Do you just throw that down the drain?

I do not have a resin printer so please forgive my ignorance. If I get the pro version is an additional UV source needed for curing the prints or does it cure within the unit itself?
Thank you.
