Huge 3D Printer You Can Make · 模型 15921
This is the NS-600. I built it during COVID lockdown. Its print volume is over 600mm x 300mm x 450mm. I put a lot of effort in to this model to capture all the detail accurately so you can make it too. Follow this link to see it in action: https://www.youtube.com/watch?v=o8HUuwkqKC4&t=529s Most parts can be found on Amazon, eBay, or AliExpress. A few optional components can be fabricated. Fusion 360 can generate CAM paths for those parts. - X carriage and drag chain brackets are machined from 1/8" (3mm) angle aluminum stock. - Y strain relief / drag chain brackets are machined from maple, but could be 3D printed. I recommend wood though. Using thermoplastics near a heat source isn't a great idea, and I find using 3D printed parts on a 3D printer to be distasteful. - Y carriage plate is machined from 1/4" (6mm) aluminum stock. - Z belt tension bracket is machined from 3mm aluminum stock. (The Z belt assembly is optional, but recommended. It keeps the gantry from sagging unevenly.) I included both linear rail motion and V-wheel motion. Hide the parts you don't want to use. If you intend to use linear rails for Y motion, you'll need to fabricate the Y carriage plate, as it has the mounting holes for the MGN12H blocks. If you prefer rollers, you can use two stock CR-10 bed carriage plates. For linear rail X motion, you'll need to fabricate the bracket. Wheel brackets are on Amazon, eBay, or AliExpress. There are two power supplies -- 12V for the control board and hot-end, and a modified 24V for the two 12V bed heaters. The heated beds are wired in series for safety. If one fails they both stop. I only use one thermistor. The 24V PSU is modified to deliver 18V. This prevents too much current going to the 12V heated beds. Replace the Mean Well LRS-350-24's stock trim potentiometer with a 10kΩ, and dial it back until the unit delivers 18V. The print surface is a custom mirror. I modeled an extra large one to maximize print area, but you could use a 620mm x 310mm for a perfect fit on the heated beds. I use stainless steel Torx screws for everything because Torx is the superior fastener drive. When building something of this nature, you need to fasten and re-fasten often. Torx will not wear out while hex and Philips degrade quickly. Torx can take high torque and will last through many fasten-unfasten cycles. The shaft will shear before the head will cam out. You'll have to roll your own firmware. Mine is based on a Marlin CR-10S replacement.
