MRRF2019 was fantastic and in this video we take a look at all the awesome CoreXY 3d printers that were at the show.

The Reprap movement is alive and well at #MRRF2019. While there were many amazing 3d printer builds at the Midwest Reprap Festival 2019, what caught my was the corexy 3d printer designs and builds. The core-xy motion system is my favorite machine kinematics. The belt routing path is clever and useful for 3d printer motion. For such a small grass roots event like MRRF 2019 you can find some of the best corexy 3d printers of 2019.

Rise of the E3D Toolchangers
Last year at MRRF 2018, E3D intrigued listeners as they explained their tool changer design. It wasn’t the first time that RepRap designers have implemented automatic tool changing into 3d printing technology. But E3D caught the imagination of everyone and showed us a glimpse of the future of 3d printing. The Toolchanger is an advanced 3d printer setup that allows you to have multiple print heads available but only one located onto the XY gantry. This allows you to have multiple materials and colors but keep the printer fast with the light weight motion system.
Ever since the Tool Changer presentation many designers and builders have been racing to develop their own system or E3D Tool Changer clone. Not that E3D minds, they’ll be publishing the complete design open-source on Thingiverse soon.
If you havn’t heard of the RailCore 3D Printer you should check it out. It’s pretty much the best corexy printer kit available at the moment. In addition to it’s slick design the printer uses linear rails on all three axis and has the best print quality compared to the many other designs. We had a chance to catch up with RailCore Labs and Project R3D at the show. RailCore Labs is the creator of the RailCore line of printers and Project R3D is the main manufacture of the printer and kits. The machine design is done well and there are a ecosystem of upgrade available. In addition to the crew of RailCore exhibiting at #MMRF2019, 713Maker and Mandala Rose Works were also exhibiting. The two companies manufacture all the really pretty CNC machined aluminum upgrades and parts that make up the RailCore ecosystem. The RailCore printer in image below has a custom all metal machined aluminum enclosure manufactured by 713Maker. 713Maker also manufactures other machined aluminum upgrade parts for a range of delta printers and other various printer kits that are in need for metal upgrades.
Prusa XL
Unfortunately MRRF2020 was canceled due to the Coronavirus but maybe next year we’ll get a glimpse of the Prusa Research’s project. Rumors of the next Prusa printer are surfacing and look like they’re coming out with a Prusa corexy with a 400mm build area. #MRRF2021 will be interesting once we get a preview of new community developments. We all look forward to seeing what will be next. See you next year my friends!

![TXRX Labs: Delta 3D Printer
Some friends and I from TXRX Labs have been working on a delta 3d printer project for a few years now. This was the promo video of the first finished product. Our group leader Greg Southerland named the 3d printer the Igus Delta. Team delta has moved onto new project that includes a 12ft large scale delta 3d printer that has a 4ft x 4ft build volume.
This is the work of Greg Southerland of TX-RX Labs of Houston. Greg along with a small work group have designed and built a 3D printer. This work is being given to the 3D Printing community

We are a project based group of makers, inventors, tinkerers, artists, crafters, and coders. We are housed in a 30,000 square foot facility which includes a rapid fabrication lab, electronics lab, metal fabrication shop, wood workshop, machine shop, bike maintenance and repair shop, art lab, computer lab and coworking space.
A delta robot is a type of parallel robot.[2] It consists of three arms connected to universal joints at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector. By contrast, a Stewart platform can change the orientation of its end effector.[3]
Delta robots have popular usage in picking and packaging in factories because they can be quite fast, some executing up to 300 picks per minute.

History
Commercial pick and place robots
The delta robot (a parallel arm robot) was invented in the early 1980s by a research team led by professor Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland).[5] After a visit to a chocolate maker, a team member wanted to develop a robot to place pralines in their packages.[6] The purpose of this new type of robot was to manipulate light and small objects at a very high speed, an industrial need at that time.
In 1987, the Swiss company Demaurex purchased a license for the delta robot and started the production of delta robots for the packaging industry. In 1991 Reymond Clavel presented his doctoral thesis Conception dun robot parallèle rapide à 4 degrés de liberté,[7] and received the golden robot award in 1999 for his work and development of the delta robot. Also in 1999, ABB Flexible Automation started selling its delta robot, the FlexPicker. By the end of 1999 delta robots were also sold by Sigpack Systems.
In 2017 Harvards Microrobotics Lab researcher Hayley McClintock miniaturized it with piezoelectric actuators to 0.43 grams for 15 mm x 15 mm x 20 mm, capable of moving a 1.3g payload around a 7 cubic millimeter workspace with a 5 micrometers precision, reaching 0.45 m/s speeds with 215 m/s² accelerations and repeating patterns at 75 Hz.
The delta robot is a parallel robot, i.e. it consists of multiple kinematic chains connecting the base with the end-effector. The robot can also be seen as a spatial generalisation of a four-bar linkage.[9]
The key concept of the delta robot is the use of parallelograms which restrict the movement of the end platform to pure translation, i.e. only movement in the X, Y or Z direction with no rotation.
The robots base is mounted above the workspace and all the actuators are located on it. From the base, three middle jointed arms extend. The ends of these arms are connected to a small triangular platform. Actuation of the input links will move the triangular platform along the X, Y or Z direction. Actuation can be done with linear or rotational actuators, with or without reductions (direct drive).
Since the actuators are all located in the base, the arms can be made of a light composite material. As a result of this, the moving parts of the delta robot have a small inertia. This allows for very high speed and high accelerations. Having all the arms connected together to the end-effector increases the robot stiffness, but reduces its working volume.
