PolTur XL v.2 (The lack table printer)

thingiverse

This is a significant upgrade to my Poltur XL, featuring all-new designed components and the widely available 2020 extrusion. As a result, it's assembled using standard T-slot nuts and bolts. I've leveraged the benefits of an IKEA Lack table to create a substantial portion of the printer's frame, combining this with the use of extrusion has resulted in an incredibly rigid and solid structure. A secondary advantage of using the wooden construction of the Lack table is its inherent vibration-dampening properties, which significantly reduce the printer's noise levels during operation. Although the printer can utilize standard I3 X-axis parts like metal carriages equipped with bearings due to its identical rod spacing as a stock Prusa I3 (meaning it can use multiple I3 mods available on Thingiverse), I'm including my custom "bearingless" designs for both the X-carriage and Z-axis. These have proven to be extremely versatile, reliable, and produce an absolute minimum of noise and vibrations. I also provide various quick-release extruder mount designs that fit onto the carriage. The X-carriage itself can be used with more standard extruder mounts if desired. All parts except for the LCD enclosure are sized under 100mmx100mmx100mm, making them producible on smaller low-budget printers like Hobbyking's Mini Fabricator V2 and similar. This means you can create this large-scale, high-output printer using the smallest type of 3D printers available. 11/04/2018: I've added the "Poltur XL v2 complete" STL file, which can be opened in any 3D viewing program like Windows 3D Builder and used as a reference for part locations when building.
