A bioprinter was used to create patterned hydrogels based on a sacrificial mold. The poloxamer mold was backfilled with a second hydrogel and then eluted, leaving voids which were filled with a third hydrogel. This method uses fast elution and good printability of poloxamer to generate complex architectures from biopolymers.

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.

Using modern plastic extrusion and printing technologies, it is now possible to quickly and inexpensively produce physical models of X-ray CT data taken in a laboratory. The three -dimensional printing of tomographic data is a powerful visualization, research, and educational tool that may now be accessed by the preclinical imaging community.
FAQs
The computer-aided model specifies the mold’s shape and dimensions, then software converts that geometry into printing instructions. Layer-by-layer deposition or curing follows those instructions to reproduce the designed form. This digital connection allows researchers to modify features before fabrication, compare alternative geometries, and create customized structures without rebuilding the design process from the beginning.
The mold material and its surface features influence how the target material is shaped during casting, molding, or gel formation. Geometry determines the overall architecture, while surface characteristics can affect the resulting interfaces and fine features. Selecting these variables deliberately helps bioengineers produce structures suited to a particular scaffold, device, or cell culture configuration.
Complex architectures allow researchers to investigate biological systems with controlled three-dimensional organization rather than relying only on simpler forms. A digitally designed mold can incorporate intricate features that would be difficult to reproduce consistently by other approaches. This geometric control supports experiments that examine how structure influences tissue-engineering scaffolds, microfluidic devices, and cell culture platforms.
A typical workflow begins with a computer-aided design of the desired mold, followed by conversion of that model into printing instructions. The mold is fabricated through deposited or cured material, after which its selected geometry, material, and surface features can be used to shape another material or form a gel. The resulting structure is then used for the intended biological experiment or component.
These molds can support the fabrication of tissue-engineering scaffolds, microfluidic devices, cell culture platforms, and patient-specific biomedical components. Their value differs by application: scaffolds require controlled architecture, microfluidic systems depend on designed channel features, and patient-specific components benefit from customized geometry. The same design-to-fabrication approach therefore serves several experimental and biomedical development needs.
They are particularly useful when researchers need rapid prototyping, customized structures, or repeated fabrication of a designed geometry. The accessible digital workflow makes it practical to revise a model and test new versions during development. In bioengineering, this can shorten development cycles while preserving geometric control across studies of biological systems and emerging biomedical components.
