Bigg3r - (pronounced Bigger) 3D PrinterThis design is based on RichRap's very cool Sli3DR 3D printer, optimized for a larger build area, uses smaller 15mm slotted extrusion and should be easier to scale in any of X, Y or Z.Work in progress... haven't built one yet. YMMV.Attributions - Please see the RichRap Sli3DR and 3DR projects for most of the original parts used in Bigg3r.Credit to Openbeam for brackets and extrusions, Tantilus for Z-carriage design.
