Assignment

#7 MAKE and POST Casting Bibenda Actuator

• POST photos of process, and about lessons-learned

#8 READ and POST about a Silicone Soft Robotics paper that seemed interesting to you chosen from an academic source (NYU Library Article Search or Google Scholar)

READ and POST about a Silicone Soft Robotics paper

• I looked through both Google Scholar and the NYU Library and landed on this open access paper from Nature that was published this month.

  • The title is Bio-inspired 3D printing approach for bonding soft and rigid materials through underextrusion

  • The authors from the University of Twente in the Netherlands talk through the a 3D printing approach of using what are usually considered undesirable printing defects in industrial FDM like oozing or underextrusion as a way to adhere soft and hard materials together in contrast to things like silicone glue and have several ways of testing it

    

    • Uses EcoFlex and Dragon Skin for testing and also shared resources for updating the GCode for slicing and other casting tips

  • This overlaps with my work in biofabrication and bioprinting this semester, adapting 3D printers to print soft and biomaterials

• I’d like to try reproducing a version of this technique or at least being inspired by it for creating a plucking type of actuator a guitar or other type of string instrument

MAKE and POST Casting Bibenda Actuator

3D printing the core

• This step went smoothly after I removed some stuck filament from my 3D printer to print in white PLA, I used BambuStudio for the slicer

Creating fabric restraint for core

• I messed up the measurements on the first one but another was easy to make and got me familiar with soft lab supplies!
