We don't suggest curing SC resin using regular UV nail boxes. UV nailbox bulbs are at 365nm. SC needs 405nm light. At least 30-50w, as close as possible to the model, curing for 3-5 hours depending on size and thickness of the model.

certainly not enough to 99% result ..... I tried 405nm and 100w worked well 85% result...... but if you want more you have an even better lamp.
I'm probably going to start producing curing boxes....

This makes the pockets shallower and less likely to break. If I'm doing a job where I have to repeat as in school rings I try to taper the letters if possible. This reduces breaking dramatically and also pretty well eliminates bubbles being caught in the lettering. This takes extra time at the design stage but you get a lot less failures.
I do this as well but in t-splines for the same reasons wawatobi. For basic fonts I (usually get the children to do it) create the alphabet for reuse and have them in the file at the smallest size and optimal depth I can produce. From there just reimport for reuse and scale 2d. The beauty of t-splines is you can tweek the exact area of your font really easily if you have troubles.
I find t-splines takes all the sharp corners away, vertical and horizontal which helps with the harder to do engraved fonts. It allows you to dome the bottom of an engraved font and allows to a degree the metal to flow better over it rather than into. Embossed does not put as much stress on the investment IMO as it is supported by a heavier mass of investment. This was discussed on the discourse forum the other day. Some who do not have sub-d prefer to use hightfield in Rhino which is also discussed.

Good to see people getting results with Soluscast.
