As a kid, I loved going to the Disney Store at the local mall, usually with my grandma. At the back of those iconic stores was a bin of stuffed toys of beloved characters, and I wanted to hug all of them. Eeyore and Sorcerer Mickey were my particular favorites, and eventually the happy days came when I was able to take each of them home. It probably would have blown my young mind if anyone had even suggested that thanks to Disney research, the day might come when I would be able to 3D print my own soft toys and other soft items.
A new paper from Disney Research, “A Layered Fabric 3D Printer for Soft Interactive Objects-Paper,” penned by Huaishu Peng (of Disney Research Pittsburgh and Cornell University), Jen Mankoff (of Carnegie Mellon University), Scott E. Hudson (of Disney Research Pittsburgh and Carnegie Mellon University), and James McCann (of Disney Research Pittsburgh), details a whole new kind of 3D printer.
Unlike the FFF, FDM, SLS, and SLA 3D printers we’ve already become used to seeing, the new machine out of this lab prints with an all new technique. The trick of it lies in the material; rather than using plastic, metal, or even paper or food, this 3D printer uses fabric.
Picture a desktop 3D printer, and the filament spool is probably a prominent feature in this image. Now, replace that image of the filament spool with a roll of fabric. That’s the best way to imagine this new machine. And coming from Disney Research, this seems almost as magical as Cinderella’s birds and mice coming by to help her with her fabric needs.
The Disney Research 3D printer works in a layer-by-layer fashion, laying down thin fabric one piece at a time. Each layer of fabric is trimmed by a laser cutter, bound by a pressure sensitive adhesive to the previous layer, and heated to activate the adhesive. Once the process is completed, the finished product is a not-immediately-impressive fabric cube. Just like many other 3D printed objects, though, the supports have to be removed–in this case, that’s the spare fabric that fills out the cube. With this extra fabric peeled away (the bright side of fabric as the print material: no tools required!), the inner object is revealed.
- Turn on vacuum to hold fabric to cutting table
- Cut 2D layer shape(s) and bounding box in fabric
- Raise bonding platform to touch cut fabric
- Release cut fabric by turning vacuum off
- Lower bonding platform and advance fabric
- Heat bond new layer to print
While initially, this machine might seem as though it has little practical application outside of making lovable squishy friends for kids, the team at Disney Research noted that these models can be enhanced through the addition of conductive fabrics, electronics, even a wireless near-field communication (NFC) device that can light an LED on a smartphone case. The 3D printer is able to use two fabrics in one print job, allowing for the integration of such conductive materials, such as wiring, into one of the fabric sheets.
A full list of specs is not yet available (nor is any information about potentially bringing this prototype printer to market), but the paper’s authors worked on a 10″ x 10″ x 10″ build volume, noting that “printers of larger sizes could be easily constructed using this same design.”
“The primary physical structure of the printer is constructed with off-the-shelf aluminum extrusion,” they write. “Following the design of a number of current consumer 3D printers, motion is actuated with stepper motors and timing belts for the X and Y axes, and with a paired set of stepper motors and lead screws for the Z axis.”
With Disney stepping into the arena, another major global company is dipping its toes into the 3D printing industry–which could have a major impact. Disney’s researchers and famous teams of imagineers are well-known for bringing innovative concepts into reality, and their creativity could go a long way in the field of 3D printing.
