LulzBot Bio FRESH 3D Bioprinter for Soft-Hydrogel Fabrication with Heated Borosilicate Bed

The LulzBot Bio FRESH 3D Printer is a specialized bioprinter designed for *soft-hydrogel bioprinting* applications in biotechnology, tissue engineering, and molecular diagnostics. Utilizing Fluid Deposition Fabrication (FDF) and a proprietary FRESH method, it stabilizes delicate biomaterials such as collagen and alginate within a supportive bath to prevent strand collapse and maintain structural fidelity during printing.

Key features include:

• Syringe Pump Extruder compatible with 2.5mL, 5mL, and 10mL volumes, enabling precise extrusion control ideal for hydrogel scaffolds and organoid matrix fabrication.
• High-resolution layering, achieving a minimum layer thickness of 50 µm and positive feature size down to 80 µm, allowing detailed soft tissue model construction critical in synthetic biology and bioprocessing workflows.
• XYZ positional accuracy of 10 µm in X and Y axes and <5 µm in Z, supporting reproducible and accurate biomanufacturing processes.
• Heated borosilicate glass print bed reaching up to 110°C, ensuring temperature stability for thermosensitive hydrogels and maintaining print consistency in variable lab environments including biosafety cabinets.
• Build volume measuring 160mm x 160mm x 89mm accommodates a broad range of applications from small tissue constructs to complex extracellular matrix mimics.
• Operating ambient temperature range from 5°C to 40°C, suitable for biochemical and biomedical engineering labs.

The compact design fits standard benches or laminar flow hoods, facilitating hygienic workflows and ease of sterilization between runs. The open-source ecosystem enables customization of tool heads and print profiles, meeting the evolving demands of bioprinting research in molecular cloning, synthetic biology, and biopharmaceutical production.

This bioprinter is an essential tool for researchers requiring precise control over soft hydrogel biomanufacturing, widely adopted in tissue engineering, live-cell matrix fabrication, and fluorescence-based biomaterial studies. Its reliable handling of collagen and alginate makes it critical for molecular diagnostics and biotechnology labs seeking scalable bioprocessing solutions.
