US 2026/0076317 A1 · SYSTEMS AND METHODS FOR FABRICATION, MAINTENANCE, AND REPAIR OF SYNTHETIC LIVING WOOD TISSUE

Abstract

The invention provides an integrated system and method for fabricating, regenerating, and maintaining synthetic living wood tissue constructs. The platform utilizes a formulation subsystem that prepares plant-derived precursor cells, lineage-directing Exomix signaling vesicles, and a supportive cellulose-based hydrogel into a printable bio-ink. An additive biofabrication subsystem generates structured constructs containing organized cambial, xylem, and phloem domains, microfluidic vascular channels, and embedded niche reservoirs. A maintenance and repair subsystem preserves tissue viability, delivers targeted regeneration cues, and supports long-term integration with damaged or aging wood substrates. Environmental control modules regulate electrical, mechanical, thermal, and biochemical parameters to guide differentiation and maturation. The invention enables sustainable production of regenerative wood materials with enhanced strength, decay resistance, and customizable properties, addressing limitations of natural wood through controlled biomanufacturing and restoration workflows.

Dependent claims

A synthetic living wood tissue fabrication and restoration system comprising:

a) a formulation preparation subsystem configured to generate an Exomix, a bio-active plant-cell-based formulation;
b) an encapsulation unit configured to package an Exomix formulation into vesicles for controlled delivery;
c) an additive manufacturing subsystem arranged to deposit successive layers of the bio-ink to form a synthetic living wood tissue construct that incorporates niche reservoirs and a microfluidic channel network;
d) an environmental control module configured to maintain a controlled process environment of temperature, humidity, and gas composition suitable for plant cell viability during fabrication and post-fabrication maturation;
e) a maintenance and repair delivery subsystem operable to apply a maintenance material comprising the Exomix formulation to the synthetic living wood tissue construct after fabrication;
f) a control system comprising a processing unit and feedback loop circuitry configured to coordinate operation of the formulation preparation subsystem, the encapsulation unit, the additive manufacturing subsystem, the environmental control module, and the maintenance and repair delivery subsystem.
