Hi Guys
I know Jak has one.
If you have one, Which and any advice would be good please?
I am considering a Anycubic Photon DLP

I know little about DLP printers. Looks like they have VERY good resolution. I had looked at SLA printers but didn't like the idea of having cans of resin around, and they usually have small print size unless you want to spend a lot. That's why I went with an FDM printer using reals of filament. I have the Prusa i3 MK3 with MMU2S multi loader. The MMU allows me to print a design that contains 5 different colours or materials. Print area is about 8" x 9" x8" high. This is $795, plus $299 for the MMU2S upgrade. I'm very happy with the Prusa. Anycubic Photon DLP has a print area of about 4.5"x 2.5"x 6.5" high. VERY good resolution! Seen good reviews. Fumes are contained where the Prusa is open, but PLA filament gives off very little in the way of fumes. But I wouldn't run one in a small room. I have the whole basement. It's about what you want? Resolution? Materials? Size?

Thanks Jak. Great info. DLP, FDM, SLA???

I run a 3D print lab, among other things...
DLP and SLA are both acronyms for processes that harden a liquid resin using a (usually UV) light source. As Jak says, excellent resolution. However, not so great for end-use parts as they get brittle in a fairly short amount of time. Much better suited for fitment studies during the design process.
FDM is melting thermoplastics (such as ABS and PLA) in layers. Much better for end-use parts. However, consumer-grade printers with no enclosure are hard-pressed to print ABS without warping the parts. They do better with PET and PLA.
I'm fortunate that I can work with commercial-grade printers that "just work". The big one I operate has a build chamber that one can climb inside (not recommended!) and a build envelope of 3'W x 2'D x 3'H. It can print high temperature thermoplastics that can stand up to the extremes of the aerospace industry. We print for Lockheed when they have overflow jobs...only fair since they donated the ~$600k to allow us to buy it!
Be prepared for some serious trial-and-error until you get your parameters dialed in...it can be elusive.
