The unique printer is a modular machine platform that uses lead screw driven motion to allow for an extended range of applications.
Most 3d printers use belt driven motion in the x and y axis to increase print speed but loses quality when more weight is applied to the gantry or carriage. The lead screw used on the Workhorse has a high helix pitch with multiple threads to allow increased print speeds while maintaining the quality provided from lead screw and ball screw motion.The robust and rigid system is particularly useful in applications that add more weight to the gantry or carriage. Materials such as clay, chocolate, plastic pellet extrusion or other foods can increase weight that is moved around which results decreased quality or print speeds. Workhorse Printer's are available to purchase in Machined Component Kit, Hardware Kit or Complete Kit. Currently, Workhorse Printers fully assembled are only available locally in Houston Texas or for Beta Testers with approval.

![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

HOUSTONS HACKERSPACE - 205 ROBERTS ST. HOUSTON, TX 77003
TXRX is a non-profit Hackerspace in Houston, Texas offering classes, lab space, and our collective knowledge to help you launch your ideas and projects. 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.
