That is really tempting, the resin printer. The build area is one limitation, depending of course on what you want to make.
There was talk recently of 3D printing?some boxes, I bet this would make a nice box and you "should" be able to make some intricate latches.

For us "newbies" send a video "snap shot"? please of this new machine.
I have? a few euros in sludge money from musical instrument repair, it?s got to be spent as

Thanks. I am still trying to understand but I noticed one huge difference between the two methods. UV resin printer printing speed depends only on the vertical height of the part without any regard to the weight whereas the fused filament printers depend on the mass of the part. This is because it prints layer by layer. So, if the layer (or slice) tiny or very wide it still takes the same time to cure before it moves to the next layer. So orienting the same part differently can adversely affect the time needed for finishing the print job.?
True, post processing is a cost and time consuming issue. I am using a home made UV chamber that uses UV LEDs and I realize that the light output is not strong enough. Leaving the printed part under sun seems to an easier way.?

My son bought me a new 3D printer last week. It is unit, uses SLA - Stereo Lithography technology, also called DLP or Digital Light Projector technology. Basically UV Resin (liquid photopolymer) is poured into a tray with transparent bottom that sits on top of a high resolution LCD screen. The print platform dips into the liquid resin. The part gets printed when the resin hardens as the LCD lights up layer by layer and the platform moves up every few (~10) seconds. The part being printed hangs down from the platform. When done it is pulled out, washed in a bath of Isopropyl Alcohol and then additionally, kept in a UV lamp chamber for additional curing. Also can be kept under direct sunlight alternatively.?
