1. A system for manufacture of a tool, the system comprising:
a deposition reactor configured for molecular layer deposition or atomic layer deposition of powder to manufacture coated particles, the deposition reactor comprising:
an inlet for substrate particles;
an inlet for precursor gases; and
a reaction tray configured to collect coated particles, the reaction tray comprising pores configured to permit passage of gas therethrough but not passage of substrate particles therethrough,
a fabrication unit configured for 3D printing of the tool; and
a controller that controls the deposition reactor and the fabrication unit,
wherein the fabrication unit and the deposition reactor are integrated for automated fabrication of the tool using the coated particles from the deposition reactor as building material for the 3D printing, and
wherein the deposition reactor is configured so that the precursor gases initially contact a first side of the reaction tray and so that the substrate particles are disposed on a second side of the reaction tray opposite the first side of the reaction tray.
