Our bodies are unique and constantly changing. 3D-/4D-printing can be used to personalize orthotic devices for different shapes and sizes, as well as passively adapt to changes in our bodies. #multifunctional #splint #surfaceTextures #shapeChange #variableStiffness

This #4Dprinted personalized #orthosis provides adaptive fit and comfort by integrating soft/stiff surfaces, moisture-activated #shapechanging zones, and insertable components such as magnets and aligners into a highly #functional device for the #medical and #sports industries.

The #Hybrid #AdditiveFabrication of wood actuators and #3Dprinted #Metamaterials can be utilized for the production of large-scale doubly curved #ShellStructures, as explored and demonstrated in the master's thesis project of Karen Antorveza, Laura Kiesewetter, and Eda Özdemir.

The large-scale structures produced from this #hybrid #additive #fabrication process are programmed to transform their shapes in response to changes in ambient conditions. #4Dprinting #construction #automation

[Tiffany Cheng @multimeso]

Extrusion-based #3Dprinting enables a high resolution of detail in programming #metamaterial structures. By leveraging industrial robot platforms, 3D-printed meta-structures can be upscaled and tailored through a continuous, interwoven, and layer-by-layer extrusion trajectory.

[Tiffany Cheng @multimeso]

In transitioning from small-scale hobbyist 3D-printers to large-scale robot extrusion platforms, the correlation between #printingparameter and #mechanicalproperty is preserved. By modulating these #functionalpatterns, mechanical properties can be tuned in specific directions.

[Tiffany Cheng @multimeso]

Based on the interplay between their #hinge #geometry, #bilayer #structure, and #responsive #material, each #4Dprinted structure here computes its own #folded #shape by equalizing its moisture content to the surrounding #environmental conditions.

[Tiffany Cheng @multimeso]

The motion of #selfshaping materials can be amplified by #4Dprinting building blocks of #bilayers in greater assemblies, creating #mechanisms that autonomously expand (and contract) considerably in size and volume.

[Tiffany Cheng @multimeso]

Through the #design of its #mesostructure and by controlling the extrusion trajectory during #fusedFilamentFabrication, #4Dprinted material systems can be #programmed with custom shapes and #movements — enabling designs with new forms of #responsive, spatio-temporal behaviors.

[Tiffany Cheng @multimeso]

#FusedFilamentFabrication (the most common and affordable type of #AdditiveManufacturing) is well suited for structuring printed parts at the #mesoscale and mimicking the self-shaping behavior of plants — a process called #bioinspired #4Dprinting.

@CornellAAP I am thrilled to be joining #CornellAAP in the coming spring semester!

[Tiffany Cheng @multimeso]

I am excited to finally share the news of my appointment as #AssistantProfessor at the @CornellAAP Department of Design Tech!

Until my relocation to the US from Germany in January 2025, I will be introducing my previous work upon which the #MULTIMESO Lab is based.

Stay tuned…!
