New 3D Printer: Open Source & Closed Loop Motor Control

After three years of development, we are proud to offer the first 100% open source and closed loop 3D printer. The Closed Loop (CL) 1720 is a very strong, reliable system built on an extremely rigid extruded aluminum frame. Additionally, the CL1720 is based off of robust and proven open-source software that is 100% free and open to the 3D printing community. Typically, closed loop systems that are included on 3D printer or CNC machines are very expensive and do not allow for software upgrades past what the company owning the software allows. With the AaronLouis CL1720 and Open Loop (OP)1720 systems, the software running these industrial grade printers is completely free.

The standard versions of the CL1720 aand OP1720 systems were designed to push 3D printing past rapid prototyping. This goal is achieved by expanding customer filament options to anything that can be extruded within the 315 deg c. extruder nozzle and 648 deg c. hotbed temperature range. Our high temperature versions of the CL1720 and OP1720 systems are capable of extruding at temperatures above 400 deg c. This very wide temperature range allows for virtually every filament option to be available.

In addition, the extruders that are included as part of the CL1720 and OP1720 systems are based on an all metal design along with a stainless steel drive gear that is powered by NEMA11 motors that are 13x the torque of standard NEMA11 motors. This advanced extruder design, combined with a low-profile, removable hotbed design that is based on two pieces of .25″ thick 6061 aluminum plates is extremely durable and is ready for extended use. This hotbed comes with three high-temperature, low profile heater elements that are capable of reaching temperatures at 648 deg c. Finally, the hotbed is driven by a 16MM ballscrew drive to increase accuracy and extended durability. This ballscrew configuration is powered by a high-torque (400oz/in) NEMA 23 stepper motor. This system was intentionally over-engineered to improve system reliability, durability, and allow for worry-free printing.

We are excited to offer the first open source, closed loop 3D printer that is completely turn-key. The following video provides an example of how closed loop motor control allows for continued prints, even when you push the extruder completely away from the object being printed. We do not recommend attempting this demonstration with any printer, this video is simply designed to demonstrate the accuracy and reliability of the CL1720 system.

If you are interested in the OL1720 or the CL1720, please keep an eye on our website as the Kickstarter video is nearing completion. Estimated launch planned for April 2017.
