This work aims to define a novel integration of 6 DOF robots with an extrusion-based 3D printing framework that strengthens the possibility of implementing control and simulation of the system in multiple degrees of freedom. Polylactic acid (PLA) is used as an extrusion material for testing, which is a thermoplastic that is biodegradable and is derived from natural lactic acid found in corn, maize, and the like. To execute the proposed framework a virtual working station for the robot was created in RoboDK. RoboDK interprets G-code from the slicing (Slic3r) software. Further analysis and experiments were performed by FANUC 2000ia 165F Industrial Robot. Different tests were performed to check the dimensional accuracy of the parts (rectangle and cylindrical). When the robot operated at 20% of its maximum speed, a bulginess was observed in the cylindrical part, causing the radius to increase from 1 cm to 1.27 cm and resulting in a thickness variation of 0.27 cm at the bulginess location

Ultrahigh-strength steels are traditionally defined as those steels with a minimum yield strength of approximately 1380 MPa. Notable examples of steels in this category include AISI 4130, AISI 4140, and AISI 4340. In many cases, maximizing the performance of these alloys requires a rather complex approach that involves a series of tempering, annealing, or stress-relieving treatments. As a result, they are produced using a variety of traditional processing methods such as casting, rolling, extrusion, or forging. These traditional methods — combined with the ultrahigh strength of the steels — often meant that the production of complex, near-net shape parts of high quality was quite difficult. In addition, these production methods often entailed repetitive treatments or long production cycles, both of which resulted in elevated production costs

Tubing for wound draining is an essential medical component used to manage the drainage of fluids from surgical or traumatic wounds. This tubing is commonly employed after surgical procedures to facilitate the removal of excess fluids (such as blood or serous fluid) from the wound site, or in traumatic Injuries where there is a need to control and remove fluids to aid in the healing process. Other uses include draining abscesses or fluid collections, helping to prevent infection, and promote faster healing, or to manage fluid accumulation in body cavities, preventing complications like seromas or hematomas. By removing excess fluids, tubing promotes a cleaner wound environment, which is conducive to faster healing

The development of microfluidic systems for lab-on-a-chip (LoC) and organ-on-a-chip (OoC) applications require precise fluid flow control. Typically, on-chip flows are controlled by integrating a microfluidic chip with external pumps that deliver fluid flow at the microscale (typically on the order of mL/min) through the microchannels. To this end, commercially available flow devices such as extrusion syringe pumps, peristaltic pumps, and pneumatic pumps have been widely used
An interdisciplinary team of University of Minnesota Twin Cities scientists and engineers has developed a first-of-its-kind, plant-inspired extrusion process that enables synthetic material growth.
