Hi guys, I'm looking to build a 3D printer that can print materials like concrete at a construction scale (about 1" high layers). This printer is just to test the material and get small prototypes of the wall systems and such. I originally was thinking of just getting the Openbuilds LEAD 1010 CNC with High Z Mod, and then attaching my own extruders and such to that. If i'm going down this path, I figured it may just be worth it to convert the LEAD to a proper gantry (where the entire X-axis moves up and down instead of just a Z-axis screw that moves along the X-axis). I'm not sure how strong the motors and everything need to be to lift the X-axis up and down (should I use dual Nema 23's or upgrade to Nema 34's?). Openbuilds LEAD 1010: https://openbuildspartstore.com/lead-cnc-1010-40-x-40/?srsltid=AfmBOopE5T2Wwren3G3rmibaCO6DiruCzIN3yLlWzCIqVQSpGfn-Timb My ideal size is something like 3.5' width, 2' depth, 2' height. Do you think starting with something like the Openbuilds LEAD is a good idea (at least starting with some of the parts, or should I start from scratch with linear rails and such?)? I would also probably be using all Duet 3 components. Gantry Style Another Gantry Style Openbuilds machine: Openbuilds 4x8 cnc My budget is around $3,000. This thing looks like it would work great for my use, but it's way out of my price point (is a cube style printer better than the gantry?): Concrete 3D printer Thanks for all the help guys.
