The possibilities of 3D-printing are ever expanding and now, it may even be possible to start fabricating soft sculpted 3D-printed toys, as discovered by researcher Scott E. Hudson from Carnegie Mellon University.
3D printing is able to rapidly pump out plastic toys, but making them soft and fuzzy has hardly been explored. By hacking a 3D printer, Hudson replaced the melted plastic material with a wool/wool blend yarn to craft a charming 3D-printed toy.
The process isn't like a knitting machine, since it's not flat and it is able to build layers upon layers by felting the soft fibers. The result is a tiny, flat-backed teddy that looks surprisingly home-made, which could have huge implications for the way soft toys are produced in the future.
