High-entropy　alloys　have　garnered　significant　attention　due　to　their　unique　composition　and　exceptional　properties.　Additive　manufacturing　technology,　with　its　distinctive　processing　methods,　offers　new　options　for　the　fabrication　of　high-entropy　alloys.　However,　due　to　the　diversity　of　high-entropy　alloys　and　additive　manufacturing　technologies,　it　is　imperative　to　provide　a　comprehensive　overview　of　the　high-entropy　alloys　produced　using　various　additive　manufacturing　methods.　This　paper　presents　a　summary　of　the　microstructure,　mechanical　properties,　and　corrosion　resistance　of　high-entropy　alloys　fabricated　using　different　additive　manufacturing　techniques.　This　paper　initially　reviews　the　impact　of　various　additive　manufacturing　process　parameters　and　the　influence　of　different　elements　on　the　microstructure　of　additively　manufactured　high-entropy　alloys.　Subsequently,　it　discusses　the　effects　of　different　additive　manufacturing　techniques　on　mechanical　properties　and　summarizes　four　strengthening　mechanisms　in　additively　manufactured　high-entropy　alloys.　Additionally,　the　corrosion　resistance　of　various　additively　manufactured　high-entropy　alloys　is　summarized.　Finally,　based　on　the　review　of　additively　manufactured　high　entropy　alloys　presented　in　this　paper,　the　current　challenges　and　future　research　directions　are　proposed.
