Title:
POWDER DEPOSITION SYSTEM CONFIGURED FOR THE MANUFACTURE OF OBJECTS BY ADDITIVE MANUFACTURING AND ASSOCIATED PROCESS
Document Type and Number:
WIPO Patent Application WO/2022/265529
Kind Code:
A1
Abstract:
The invention relates to a powder deposition system for the manufacturing of objects by additive manufacturing comprising powder deposition devices (1), which include a powder deposition nozzle; a deposition chamber (3), which comprises limiting walls and a printing table; and a curing and hardening fluid addition subsystem (8) to add the curing and hardening fluid, stored in a container (9), by means of a nozzle (10). Preferably, the system includes a platform, having horizontal displacement (7) a subsystem for removal of the curing and hardening fluid (13) comprising a layer with orifices (14); and a powder compaction roller (21). The invention allows the manufacture of objects based on several types of deposition materials, for example, cements and geopolymer cements, having flexibility for producing objects with several purposes, including construction.
