Will do when we run. They aren't my presses. I'm working with a partner injection molder. Additionally, the parts we run should have comparables from aluminum and/or P20 inserts that have already been produced... we will be replicating existing tooling for out trials, so we have proper parts to compare to.
I hope to have a couple of molding houses involved, so I'll be sure to spec-out all aspects. Presuming the simple stuff pans out a viable, we will be including tools with ejector-pins, and inserts, so not just stupid-simple straight-pull, pick-out parts. We will start with the simplest, but work our way into the more complex.
In the end it's a cost-benefit-time analysis. Given that a very capable shop can turn out a high-speed machined tool in, what, 72-hours? We'll be looking for the sweet-spot, or time/complexity limit of this technology.
Insert size will be the first consideration.... how long does it take to print the insert. From initial analysis, it's looking like a 4x4 insert will be about the limit. Larger than that, if time is the driver, then high-speed machining catches up... but! There is likely a cost component that may make up for larger inserts. If the additive workflow can save enough cash, vs machining, then it has another marketplace.... we will see!
It's not like this hasn't ben tried over the past 20-years. I'm just hoping that, with this new material, the part quality will be increased, insert cost will be decreased, and we find a nice home for additive tooling.
