Actually, I am building a delta pi currently. I am experimenting with aluminum square pipe with a small inner diameter. So far so good. Biggest issue I have encountered is the parts are being printed on a printrbot simple which has just under a 100mm cubed print area so the hotend mount would not fit. Had to cut it into pieces in software and add bolting points. Also the printrbot spread out the edges of the print so fitting them around the aluminum square pipe has been... interesting. Will post when I have printed my first few tests.
