Follow the photos as you read. Got my Photon "S" a few weeks ago. Ho scale model building is my thing. Always wanted to do proper Victorian trim at a small scale. FDM printers were never capable of detail that small. Resin printers now affordable, time to give it a try. I never bothered with a test print. I just started with a few thingivewrse items. A coachman and a greek temple. Why not? When I saw his thumbs I knew great things were about to happen. I drew a plan in Sketchup for a full size Shaker Sewing desk I will be building so why not try to print it and see what happens. It sliced and printed just fine with stock settings and slicer that came with the Photon S. Rubbing my hands together I went back to Sketchup to draw up a Victorian house with the kind of window trim I have been dreaming about in HO scale. Hours spent learning Chitubox Slicer and just press print right? Not so fast! Weeks of failures spent learning about support placement, print angles, layer thickness vs exposure time and what the hell is voxilization or a Voxel anyway? My basement was too cold for the grey resin according to my cheap Horrible Fright laser thermometer. A strip heater powered through a Dremel speed controller now keeps the vat at 30c. See the photo of the strip heater wrapped around the vat. I was getting horrible lines on my prints until I learned about pixel aliasing. Did not matter what layer thickness I used. A 30 degree twist in the Z axis solved that problem and brought the voxilization to a maximum randomness to print smoother surfaces. Apparently prints with lots of right angles suffer from this. Who knew? A few more lessons learned with failures about needing support in just the right places and I am now cranking out windows and trim the likes of which I have never seen. I now use 0.02mm at 7 seconds 30c temp. Anycubic grey. 3 bottom layers 30 seconds. Models are 30 degrees on XY and Z. I use only light support with cone contact at .3mm for these small items. I am privileged to live in an age where I can now hold in my hands, within hours, anything I can draw. How was your first experience with 3D printing?
