“…More important, however, the two-machine solution and its intermediate digital representation allow creating additional workflows by merely adding software. For example, by inserting a software filter capable of re-inserting missing geometry, we can create a machine that repairs physical objects [Teibrich et al, 2015].…”

While fabrication technologies have been in use in industry for several decades, expiring patents have recently allowed the technology to spill over to technology-enthusiastic "makers". The big question now is whether the technology will further progress towards consumers, which would allow the technology to scale from hundreds of thousands of users to hundreds of millions of users. Such a transition would enable consumers to use computing not just to process data, but for physical matter. This holds the promise of democratizing a whole range of fields preoccupied with physical objects, from product design to interior design, to carpentry, and to some areas of mechanical and structural engineering. It would bring massive, disruptive change to these industries and their users. We analyze similar trends in the history of computing that made the transition from industry to consumers, such as desktop publishing and home video editing, and come to the conclusion that such a transition is likely. Our analysis, however, also reveals that any transition to consumers first requires a hardware + software system that embodies the skills and expert knowledge that consumers lack: (1) hardware and materials that allow fabricating the intended objects, (2) software that embodies domain knowledge, (3) software that embodies the know-how required to operate the machinery, and (4) software that provides immediate feedback and supports interactive exploration. At the same time, sustained success will only be possible if we also consider future implications, in particular (5) sustainability and (6) intellectual property. We argue that researchers in HCI and computer graphics are well equipped for tackling these six challenges. We survey the already existing work and derive an actionable research agenda.

“…For instance, using support material in the design iteration use case can accomplish the same function (i.e. replacing a part of the object geometry) as by using a milling machine (see Patching Physical Objects [22]). Compared to using a mill, our approach has the benefit of not requiring additional hardware and being faster when a high temperature bath is used (minutes of dissolving vs. hours for milling).…”

In this paper, we propose a different perspective on the use of support material: rather than printing support structures for overhangs, our idea is to make use of its transient nature, i.e. the fact that it can be dissolved when placed in a solvent, such as water. This enables a range of new use cases, such as quickly dissolving and replacing parts of a prototype during design iteration, printing temporary assembly labels directly on the object that leave no marks when dissolved, and creating time-dependent mechanisms, such as fading in parts of an image in a shadow art piece or releasing relaxing scents from a 3D printed structure sequentially overnight. Since we use regular support material (PVA), our approach works on consumer 3D printers without any modifications. To facilitate the design of objects that leverage dissolvable support, we built a custom 3D editor plugin that includes a simulation showing how support material dissolves over time. In our evaluation, our simulation predicted geometries that are statistically similar to the example shapes within 10% error across all samples.

“…Current FDM printing is slow, taking many hours to fabricate larger objects. Previous research has explored different meth ods to speed up the printing process such as printing in lower fidelity [22,23] or reusing previously printed objects [34]. However, fabricating plastic layer-by-layer is still inherently time-consuming.…”

“…This allows us to repeatedly print on the same piece of fabric, repositioning it on the print bed and moving already printed sections out of the way, resulting in a continuous print larger than the printer itself. The restriction of this approach, similar to other work involving adding to existing fabrication [34], is that to prevent obstructing the extruder's movement, the gaps between each printed section must be larger than the size of the extruder nozzle. Another issue that arises is proper alignment of a textile such that printing can be done where desired.…”
