Well, if we ever need something huge built on a RepRap, now we know who to call. [Jim] over at Grass Roots Engineering wrote in to share a large 3D print he just finished, which was extruded by an equally impressive home-built 3D printer.
The part he built consists of a bunch of hollow green tubing in a criss-cross pattern and was printed in just under 2 days. He never mentions what the part is going to be used for, but at 376 x 376 x 250mm (14.8 x 14.8 x 9.84in), he estimates that this is the biggest single part printed with a DIY 3D printer.
The printer itself is based on the RepRap, but is obviously far larger. It prints using ABS plastic utilizing a maximum build area of 403 x 403 x 322.7mm (15.86 x 15.86 x 12.7in). Built over the course of 3 years, it was fully operational in 2010 but has undergone several improvements as [Jim’s] needs have changed.
It’s a fantastic looking machine, and it seems to print quite nicely. We would sure love to have one of these in our workshop.
