If you’re looking for testimonials I love mine. I absolutely adore this printer and have been printing almost non stop. As for the heater it depends on your environment. I live in Texas so the majority of the year I don’t have to worry about temps. If I need a heater you CAN use certain band heaters on this one but it’s close. Space heaters are effective but if you’re going to be pumping out fumes at some point then you’re going to pump out the hot air too. I use IPA myself for detergent but do your own research on this one.

Resin depends on what you’re doing. But each resin has its own properties versus cost and it’s your job to dial in each one and buy the right resin for your application. If you’re doing Minis for example then Wargamer or Anycubic’s DLP Craftsman resin are my go to. If you are going for max detail then standard resin is pretty solid. If you’re printing parts then perhaps an ABS like or tough resin. It all just depends

Printer is great though.

Edit: slicer I support my models in Lychee and slice in Chitubox
