Query: Ephemeral Fabrication: Exploring a Ubiquitous Fabrication Scenario of
  Low-Effort, In-Situ Creation of Short-Lived Physical Artifacts   Personal fabrication empowers users to create objects increasingly easier and
faster. This continuous decrease in effort evokes a speculative scenario of
Ephemeral Fabrication (EF), enabled and amplified by emerging paradigms of
mobile, wearable, or even body-integrated fabrication. EF yields fast,
temporary, in-situ solutions for everyday problems (e.g., creating a protective
skin, affixing a phone). Users solely create those, since the required effort
is negligible. We present and critically reflect on the EF scenario, by
exploring current trends in research and building a body-worn fabrication
device. EF is a plausible extrapolation of current developments, entailing both
positive (e.g., accessibility) and negative implications (e.g.,
unsustainability). Using speculative design methodology to question the
trajectory of personal fabrication, we argue that to avert the aftermath of
such futures, topics like sustainability can not remain an afterthought, but
rather be situated in interactions themselves: through embedded constraints,
conscious material choice, and constructive embedding of ephemerality.
