Build the efficient and reliable all metal structure 3D Printer with top notch parts. Improved significantly with new concepts for printers. Great quality and up to 400 mm/s print speed (very fast). Built with heated bed, hybrid bowden suspended extruder, and counterweight (tested printing 21 hours straight with no motors hot). Does not require many tools to be created. If tuned well it can last forever printing. Optional smart controller for computerless printing. Print any kind of thermoplastic. Cost: ~$500Build Area: 230mm (9 in) diameter, 230mm height (extend towers for higher if needed)Recommend some experience with 3D printers.Design and built by a high school student with a significant amount of 3D Printer experience, would love to hear suggestions or improvements below.Currently working on swapping carriages for other uses(ceramic, dremel, etc).
