Man bailed after 'making 3D-printed guns'

A Sydney man who allegedly manufactured guns in his living room using a 3D printer and instructions off the internet has been granted bail ahead of an April court appearance.

Sicen Sun appeared in Waverley Court on Wednesday, after police allegedly found four 3D-manufactured imitation guns, two air pistols and at least one 3D printer in his eastern suburbs unit.

They say they searched the 27-year-old's residence after he advertised one of the guns, a 3D SIG 250 pistol, for sale for $1 million dollars.

Sun's solicitor said his client was "something of a fanboy" who made the guns to resemble those in his favourite science fiction, TV shows and games.

But Detective Inspector Joe Doueihi of State Crime Command's Firearms Squad said Sun's gaming hobby was no excuse.

He is due to appear in court again on April 27.
