Buchwieser came through the youth ranks of
SC Riessersee, before joining
EHC München in 2008. He earned promotion to Germany's top-flight
DEL with the team in 2010 and during that particular season already logged his first DEL minutes with
Augsburger Panther. After his third season with
EHC München, his first as captain in
2012–13, Buchwieser was released as a free agent and signed by
Adler Mannheim on a two-year contract on April 12, 2013. He won the 2015 German championship with Mannheim and during the offseason was traded to fellow DEL side
Hamburg Freezers in May 2016. Later that month, the Freezers folded, Buchwieser became a free agent and was picked up by another DEL team,
ERC Ingolstadt, a couple of days later. ==References==
