This paper considers the design, construction, and example use of a new type of 3D printer which fabricates three-dimensional objects from soft fibers (wool and wool blend yarn). This printer allows the substantial advantages of additive manufacturing techniques (including rapid turn-around prototyping of physical objects and support for high levels of customization and configuration) to be employed with a new class of material.
We present a new type of 3D printer that can form precise, but soft and deformable 3D objects from layers of off-the-shelf fabric. Our printer employs an approach where a sheet of fabric forms each player of a 3D object. The printer cuts this sheet along the 2D contour of the layer using a laser cutter and then bonds it to previously printed layers using a heat sensitive adhesive. Surrounding fabric in each layer is temporarily retained to provide a removable support structure for layers printed above it. This process is repeated to build up a 3D object layer by…
The Budaschnozzle 1.1 comes set up to print 3mm plastic filament. With a optional PTFE tube that can be changed out in the hotend, you can print with 1.75mm filament. This video shows the quick and easy process of changing out this PTFE tube.
One of the goals in the redesign of the Budaschnozzle 1.1 was to make the nozzle easier to change out. Here is a video showing how easy it is to change out the nozzle. Notice that the nozzle is changed without needing to take the hotend off of the printer.
