Star Wars the First order stormtrooper helmet made in fiberglass resin casted and hand painted, back in 2016 right after the Force Awakens came out.  Its higher quality than the Hasbro Toy helmet, and definitely not a 3D printed helmet - has some soft inner lining and does not feel plastic like the Hasbro black series.  A great full sized 1:1 adult wearable helmet
