Expand material presence to material experience with volumetric thinking : voxel based multi-material printing in designing objects
Material serves as the first touchpoint between an object and a person. In current product development, material together with color and finishing is regarded as a separate entity from the form and function design. Every material needs to be paired with a series of optimal manufacturing processes …

Effects of Fused Filament Fabrication Process Variables on Microstructural Alignment and Intra-layer Properties in PLLA
Extrusion-based 3D printing is commonly used to produce complex structures from thermoplastics. Conventional fused filament fabrication (FFF) is used widely and forms objects through layer-by-layer deposition. However, there is often a need for thin support structures based on single print layers, …
