There are technically competent plastics that require higher temperature printing in enclosures, such as ASA, that have been developed and may be suitable.
For short range missions with limited requirement for delivery of munitions or shrapnel, such as against small drones and etc., it would seem size would not exclude utility. By my reckoning the most limiting aspect of the build would be the inexpensive camera, which would provide poor target recognition and targeting capabilities. However, this was merely a proof of concept and isn't necessarily a fully developed munition.
