Clay 3D printing is a relatively new technology and only narrow range of geometries printable if one employing commercially available slicing software. We experienced these limitations in an artist residency program where artists discovered that many desired failed to print successfully. This motivated us develop WeaveSlicer, slicer optimized for clay maintains constant wall thickness throughout the form. achieve by generating oscillating path amplitude oscillation determined form's overhang...

Electronic textiles, or e-textiles, are an increasingly important part of wearable computing, helping to make pervasive devices truly wearable. These soft, fabric-based computers can function as lovely embodiments Mark Weiser's vision ubiquitous computing: providing useful functionality while disappearing discreetly into the fabric our clothing. E-textiles also give new, expressive materials fashion designers, textile and artists, garments stemming from these disciplines usually employ...

This paper explores the idea of handcrafted electronics. We introduce a kit-of-no-parts approach to building electronics from diverse palette craft materials, which we argue is more personal, understandable and accessible than construction technology kit pre-determined components. illustrate our by describing design, construction, dissemination collection textile sensors, detailing website series workshops through share approach.

We have developed an interactive pop-up book called Electronic Popables to explore paper-based computing. Our integrates traditional mechanisms with thin, flexible, electronics and the result is artifact that looks functions much like ordinary pop-up, but has added elements of dynamic interactivity. This paper introduces and, through it, a library sensors suite paper-electronics construction techniques. also reflect on unique under-explored opportunities arise from combining material...

Embedded programming is typically made accessible through modular electronics toolkits. In this paper, we explore an alternative approach, combining microcontrollers with craft materials and processes as a means of bringing new groups people skills to technology production. We have developed simple robust techniques for drawing circuits conductive ink on enabling off-the-shelf electronic components be embedded directly into interactive artifacts. also set hardware software tools -- instance...

Digital fabrication, and especially 3D printing, is an emerging field that opening up new possibilities for craft, art design. The process, however, has important limitations; in particular, digitally designed artifacts are intrinsically reproducible. In stark contrast, traditional craft individually produced by hand. authors combine digital fabrication their work involving object destruction restoration: intentionally broken crafted artifact a printed restoration. motivation not to restore...

The field of new methods and techniques for building electronics is quickly growing - from research in materials circuit building, to modular toolkits, more recently untoolkits, which aim incorporate off-the-shelf parts. However, the standard mediums design construction remain breadboard, protoboard, printed board (PCB). As an alternative, we introduce a method circuits are hand-made on ordinary paper substrates, connected with conductive foil tape components supporting durability,...

Play-dough is a brightly-colored, easy-to-make, and familiar material. We have developed tested custom play-dough materials that can be employed in 3D printers designed for clay. This paper introduces set of recipes printable along with an exploration these materials' print characteristics. explore the design potential as sustainable fabrication material, highlighting its recyclability, compostability, repairability. demonstrate how custom-color prints constructed describe used support...

Unmaking is a counterpart to making and creating new things that has emerged as concept of interest in diverse parts the HCI community. been posed an ally sustainability, encouraging designers foreground issues relating reuse, repair, obsolescence, degradation, decay early their design process. As follow-up 2022 Unmaking@CHI workshop, this workshop will bring together researchers practitioners interested unmaking it relates sustainability focus primarily on exploring role material practices,...

Construction kits have long been popular as educational artifacts, supporting and encouraging creative explorations of engineering design; but to date, such had little connection with the new expanding field electronic textiles (e-textiles). We believe that creating an "e-textile construction kit" could provide a powerful medium engage diverse range students in electrical computer science. This paper, then, describes kit designed introduce novices electronics, computing design via...

The field of computational textiles has shown promise as a domain for diversifying computer science culture by drawing population with broad and non-traditional interests backgrounds into creating technology. In this paper, we present curriculum that teaches programming through series activities involve building textiles. We also describe two new technological tools, Modkit the LilyPad ProtoSnap board, support implementation curriculum. 2011-12, conducted three workshops to evaluate impact...
