DESKTOP HEALTH INTRODUCES THE PRINTROLL ROTATING BUILD PLATFORM FOR THE 3D-BIOPLOTTER®
An innovative add-on feature for the 3D-Bioplotter, the PrintRoll platform was designed to enable 3D printing of cylindrical medical solutions for adults and children and therefore offers a range of standard and custom drum diameters.

Desktop Health — the trusted production-grade medical 3D printing brand of Desktop Metal, Inc. — announced a breakthrough in bioprinting with the launch of PrintRoll™, an innovative rotating build platform that can produce intelligent tubular solutions for the body’s vascular, digestive, respiratory, and reproductive channels on the 3D-Bioplotter premier bioprinting system.
The 3D-Bioplotter is a highly sophisticated extrusion-based 3D printer that processes liquids, melts, pastes, gels, or other materials, including cells, through a needle tip on a Swiss-made, 3-axis gantry system with high accuracy and temperature, sterility, and design controls. 3D-Bioplotter offers eight printheads with the widest range of temperatures in bioprinting — from 2°C to 500°C (35.6°F to 932°F) — enabling complex, multi-material medical parts.
The PrintRoll add-on feature has been in development since 2019 as part of a collaboration with Johannes Gutenberg University Mainz, a public research university in Mainz, Germany.
How PrintRoll Works
The PrintRoll platform attaches to the modular build plate of the 3D-Bioplotter and features a motor-driven rotating mandrel with spring-loaded, easily exchangeable drums of different sizes. Rotating speed is tightly controlled by the 3D-Bioplotter’s easy-to-use software.
As the PrintRoll tool rotates, the printhead moves back and forth depositing material on the surface in the desired design. For example, polycaprolactone (PCL), a medical-grade, biodegradable plastic used in many FDA-cleared implants and devices, hardens quickly on the drum after the melted material is printed. In bioprinting, users typically produce a structure or scaffold in a stiff or flexible biocompatible material that is designed to repair and integrate with cells of the body, sometimes degrading after a certain period of time.
The PrintRoll comes with a 10 mm diameter drum – with 20 mm and 40 mm sizes available – designed to accommodate the development of solutions for a variety of human channels, which vary based on age and gender. Standard diameter sizes generally correspond to the diameters of the femoral artery (~10 mm), trachea (~10-20 mm), fallopian tube (~5-15 mm), aorta (~25 mm) esophagus (~30 mm), and a range of intestine segments (~40-100 mm).
The PrintRoll system supports printing hollow cylindrical structures up to 140 mm in length, depending on the printhead used. Custom sizes may also be available.

3D-Bioplotter® Continues Pioneering Bioprinting
PrintRoll continues the long history of bioprinting innovations on the world’s most researched bioprinting system, as detailed in the last 3D-Bioplotter brochure.
This tradition is also continued with CMFlex™ — the first 3D-printed regenerative bone graft substitute product cleared by the FDA and the first such clearance based on manufacturing on the 3D-Bioplotter. Developed by Dimension Inx, CMFlex is an easy-to-use flexible bone graft product that is 3D printed on a standard 3D-Bioplotter Manufacturer model. This new product is an alternative to an autograft, in which a physician intrusively harvests bone from one area of a patient’s body to repair damaged or diseased bone elsewhere in the body.
