Desktop Health's™ First-of-its-kind Bioprinting Tool for Tubular Solutions in Biological Channels

Desktop Health, a reputable brand specializing in high-quality medical 3D printing and operating under the umbrella of Desktop Metal, Inc., has recently introduced a groundbreaking innovation in the field of bioprinting known as PrintRoll™. This state-of-the-art rotating build platform complements the esteemed 3D-Bioplotter bioprinting system, allowing for the creation of advanced tubular solutions designed for various physiological pathways, such as vascular, digestive, respiratory, and reproductive systems.

PrintRoll, an augmentative feature for the 3D-Bioplotter, has been meticulously engineered to streamline the 3D printing of cylindrical medical solutions, catering to both adult and pediatric needs. This platform boasts a diverse selection of standard and customizable drum diameters, rendering it adaptable for an array of medical applications.

Having garnered recognition as the world's inaugural commercial bioprinter, the 3D-Bioplotter has undergone continuous evolution spanning over two decades, establishing itself as a scalable solution for both research endeavors and end-use part manufacturing. With its modular capabilities and a repertoire of eight distinct printheads, users can enhance their printers even long after the initial purchase, now including innovative features like PrintRoll.

This advanced extrusion-based 3D printer exhibits proficiency in processing an array of materials, encompassing liquids, melts, pastes, gels, and cells, all channeled through a precision needle tip mounted on a Swiss-engineered 3-axis gantry system. This configuration ensures exceptional precision in terms of accuracy, temperature control, sterility, and design intricacy. The 3D-Bioplotter's expansive temperature range, spanning from 2°C to 500°C (35.6°F to 932°F), renders it apt for the fabrication of intricate, multi-material medical components.

Affixed to the 3D-Bioplotter's modular build plate, the PrintRoll platform integrates a motor-driven rotating mandrel, accompanied by easily replaceable drums of varying sizes. As the PrintRoll apparatus rotates, the printhead dispenses material onto the surface in accordance with the desired design parameters. For instance, medical-grade biodegradable materials such as polycaprolactone (PCL) swiftly solidify on the drum post-printing.

The PrintRoll system facilitates the printing of hollow cylindrical structures, extending up to 140 mm in length, contingent on the chosen printhead. Furthermore, the platform's configurable design attributes and library of honeycomb patterns empower the 3D-Bioplotter to undertake 3D printing of a broader spectrum of materials, all crucial for significant structures. These structures can subsequently be detached from the PrintRoll once the printing process is complete, yielding components distinguished by their high resolution and reproducibility.

The PrintRoll platform is presently open for pre-orders, with shipping anticipated in the fourth quarter. Its debut signifies a momentous stride forward in bioprinting technology, holding considerable promise for medical research and the formulation of tailored, personalized medical solutions engineered to harmonize with diverse physiological pathways within the human body.
