This protocol describes a platform for fabricating self-assembled tissue rings in variable sizes using a customized 3D-printed plastic mold. PDMS negatives are cured in the 3D-printed mold; then agarose is cast in the cured PDMS negatives. Cells are seeded into the resulting agarose wells where they aggregate into tissue rings.

FAQs
Mold dimensions establish the overall size and geometry of a construct, while surface features can introduce channels, compartments, or anatomical contours. These physical cues help organize biomaterials, cells, or tissue-engineered materials into predefined spatial arrangements. In bioengineering studies, such control supports investigation of how designed architecture relates to tissue development and construct performance.
The material must remain sufficiently workable during filling and then become stable through gelation, crosslinking, or another curing process. The selected solidification route determines when the formed material can retain the mold’s geometry and be removed. Matching the process to the hydrogel, polymer, or cell-containing material supports consistent formation of the intended structure.
Researchers can modify mold dimensions, internal compartments, channels, and external contours to represent features relevant to a particular organ or tissue. This tailoring allows the resulting construct to reflect defined anatomical or architectural requirements rather than a generic shape. Such models can support studies of tissue development and evaluation of biomaterials in a more targeted context.
A defined mold provides a repeatable spatial boundary for placing a hydrogel, polymer, or cell-containing material before it solidifies. Reusing a specified geometry can help produce constructs with consistent dimensions and designed features, reducing variation in fabrication. This reproducibility is valuable when comparing scaffold designs, studying tissue-engineered constructs, or assessing biomaterial performance.
The workflow begins by selecting dimensions and features that match the intended construct, then filling the mold with a hydrogel, polymer, or cell-containing material. The filled structure is held through gelation, crosslinking, or another curing process, after which the formed construct is removed. The resulting geometry can then be used for bioengineering studies or model development.
Supported material classes include hydrogels, polymers, and compositions that contain cells. The mold provides the temporary geometry while the selected material undergoes gelation, crosslinking, or curing. This flexibility allows the same general fabrication strategy to accommodate different tissue-engineering formulations and to create constructs whose shape and internal organization match the experimental requirement.
Custom tissue molds are useful when an experiment requires controlled three-dimensional form, defined channels or compartments, or contours linked to a particular anatomy. They support tailored scaffold production instead of relying on a general shape. Applications include studying tissue development, evaluating biomaterials, and developing regenerative medicine strategies that require specified structural features.
The principal outcome is a shaped tissue-engineered construct with controlled external geometry and, when designed into the mold, internal channels or compartments. These constructs can serve as reproducible scaffolds or organ-specific models. Researchers can use them to examine tissue development, compare biomaterials, and explore regenerative medicine strategies under defined architectural conditions.
