There are some slight gaps around the inlays, especially at the trailing edges. Those will be filled with Cotronics 4525.What's your plan for blending the edges and filling in the fin pocket corner gaps just ahead of the inlays?
I'm printing some Siraya Sculpt right now. It's exciting to see SLA printing getting more popular for applications like this.The last nosecone had a phenolic tip. The person who made that tip is busy putting his superb skills to much better use making super secret aerospace parts.
I had the idea to print the tip on my resin printer from high temp resin. The high temp SLA resins are usually meant for injection molds for rapid prototyping, but so far the parts I've made seem like it's pretty tough stuff. I had a tip print that didn't turn out so hot, so I'm going to abuse it a bit to get a better feel for how it'll hold up.
The first resin I tried is Siraya Sculpt. It's good to ~350°F and a nice gray color.

I think lots more research and testing is needed before I move forward with the 3D printed tip. It shows promise, for sure. Resin technology, especially in the engineering resins is moving pretty quick. Exciting...So forgive me for being a noob , but that 3D printed nose cone tip that you will be torture testing, will you heat it in a controlled temp environment and test it all the way to failure?
