Well done Paul with your track experiments, it is something much needed.
I too have been experimenting, but only for personal use. I decided just to try plain sleepers with alternating ties under the rail, and use spikes to fix the rails in place.
There was a major difference though in that I used a relatively cheap and cheerful printer only, rather than one which comes as part of a package. This has the advantage that I can use (cheap) resins from numerous sources, and adjust their exposure time and other values to suit my needs. This is because the manufacturer essentially sells only the printer, and relies on other manufacturers to supply the resins.
Regarding supports, I use Meshmixer or ChiTuBox to generate the supports, then export the supported model as an stl. This is loaded into the printer and printed straight off. These two programmes are free, and I would have thought that you could do the same.
However, I just printed these sleepers flat onto the printer bed so there is no cleaning up, and they come with a flat underside. Dead simple, but of course as you rightly point out, this way takes a lot more time, made worse as my printer has a smaller print area than yours.
Lastly, might it be more commercially worthwhile to print and sell individual sleepers?
Dave.
