Hands-On With the World’s First 3D-Printed Teddy Bear

Despite the existence of soft plastics and materials , 3D printers are still primarily designed to produce firmly , solid objects that do n’t have much bend or give . But a investigator at Carnegie Mellon University has successfully hacked a car to produce theworld ’s first 3D - printed chemise bearusing a proficiency call felting .

The final result looks like it was rumple by a grandparent , but while wool is the primary component , the hack 3D pressman does n’t work like a knitwork simple machine . Instead , the mat technique affect repeatedly poking the wool with a needle so that its comparatively loose fibers get interwoven with the stratum beneath it , as demonstrated in this video recording .

Surprisingly , hacking a 3D printer to felt with wool instead of extrude melted plastic was n’t terribly difficult , as Almighty Scott E. Hudson explained . And you’re able to even use the same 3D mannequin and software as you would when form with plastic , you just need to take into account wool ’s inclination to spread out and puff up up as it ’s being place down .

The process needs to begin with a base bed of exist felt , so that the first stratum of woolen has something to stick to as it ’s being intrude with a needle . But after that , the printer can create level after bed of felted wool to make up a 3D model that end up feel plush and cuddly .

The only limits to how with child you could make your teddy bear are the size of your 3D pressman ’s bed , and how much time you have to wait — since the appendage is even slower than when using extruded credit card . But Hudson ’s creation is an crucial step in the development of 3D printer , as it shew that eventually they ’ll be able to create target from almost any material . Even if teddy bear might not be the first thing we ’ll make when Star Trek ’s replicators are ultimately realized . [ ACM Digital Library ]
