>Couldn't you make the molds yourself?
Silicone is expensive. Tool steel is expensive. Equipment that can produce parts at these relatively large cavity volumes is also really expensive.

I started the design with casting and injection molding in mind, but the labor involved upfront is huge. Pic related are the first 3 I produce via casting. They were significantly more labor-intensive to produce than the printed versions because I had to pressure-cast them, clean off the flash, then drill the pilot holes to size.
>How much do the blasters cost btw?
$59 for the Hardware Kit so you can print one yourself.
$110 as a complete kit
$140 assembled

I'm not trying to produce ONE PART in quantity. I have to produce 20+ parts at quantity. That's the problem. The investment cost of a single mold I can stomach should I want to reproduce one part that I don't need to revise anymore. But I don't have enough cash/credit or enough comfort with the kind of investment risk involved in getting 20+ molds produced. Printing allows me to completely avoid the financial risk/gamble of tooling costs.
