As humanity battles the Ringhead aliens in our Cold War series, they’re going to suffer losses and injury, same as war in any era.

For most of the wounded vets in our story, medical science can put them back in the field with little downtime with skin, organs, and whole limbs printed from custom stem cell bio-matter laid down with medical grade 3D printers.

Shrapnel tore through your liver? We can print you a replacement in a few hours.

Set off that thermobaric grenade a little too close for comfort? We can print yards of skin to set you back to rights. If you’re not picky about color, we’ve already got reserves in the cooler for you.

Lost an arm or a leg to a Ringhead on a rampage? We’ll lay you down in a state of the art hyperbaric healing chamber, complete with picometer resolution scanning to match your replacement to the remaining limb.

Lost both? Pick from our library of standard limbs, which can be customized to match stature and skin tones.

Most organs can be printed in less than a day. In the field, a portable unit can be used to regrow skin and major vessels to triage and stabilize until the team returns to base. Limbs are printed over the course of one to two weeks, depending on the severity and level of amputation.
