Update from my engineering shop: They're aware of the issue and tried to/intended to catch all the affected parts, but obviously missed these before they got to me. They've worked with HP (printer manufacturer) to alter machine settings to avoid the porosity seen here and don't expect to see it in the future. I sent the email and got a personal call back from the guy in charge of the printers within 9 minutes. All parts affected will be remade. Love that shop.
If anyone else noted similar porosity in that shell part, please let me know via PM or email (admin @ yotamd.com so I can get you a good replacement.
