The first one I built was a Prusa i3, but soon discovered that its wooden box frame is not stiff enough, leading me to build a more robust model using all metal components (7075 aircraft aluminum). This new printer design incorporates ideas from various online resources, including the Alminatus and Luzbot TAZ designs, for XYZ movement. Upon exploring the SolidWorks files, you'll notice six 1/4-20 tap holes at the bottom. These are for installing six adjustable screw legs with rubber damping pads to reduce vibration and noise. Adjust the front and back leg screws first to level the printer, then adjust the middle leg screws just so they kiss the support floor. What sets this printer apart is its innovative thrust bearing design incorporated into the Z-axis, which significantly improves print quality. The frame uses a standard 10 series from 80/20 (1.00" increments and a .50" Centerline). If you choose to modify this design, please indicate the specific part that needs alteration and share your knowledge so others can learn. Future plans include building an all-aluminum cold end that can be coupled with J-Head and E3D hotends. Stay tuned for more updates! You can view a detailed walkthrough of the printer in action on my YouTube channel: https://www.youtube.com/watch?v=blJxz28HuQI https://www.youtube.com/watch?v=usJId7w4_dA https://www.youtube.com/watch?v=JUHe_xVQ6cI **Getting Started** To fully appreciate this design, I encourage you to download the SolidWorks source file and explore it in-depth. You can also extract dimension data from the files if needed. Important note: I replaced M3 threaded rod with M6 threaded rod due to changes in my cad model for better compatibility with thrust bearing. All parts are relatively easy to machine with a CNC mill, so don't be discouraged if you're not an expert machinist. With practice and patience, you can create this incredible DIY 3D Printer!
