The FabLab is a platform for project-based, hands-on Science, Technology, Engineering, Arts, and Mathematics (STEAM) experiential learning at the University of Texas's Central Library. "Fab Labs," or Fabrication Laboratories , began as an outreach project from the Center for Bits and Atoms at the Massachusetts Institute of Technology. Each lab within this global network aspires and allows users to "make (almost) anything" . Selection of equipments at the Fab Lab covers a wide range of advance technology including but not limited to 3D printing , 3D scanning, Auxilliary, Cutting and Etching, Open-source electronic prototyping platform (Arduino), and Textiles.
This 3 hours workshop was designed and developed specifically for the Fab Lab by a number of students in Ememeging Technology class. I took part in planning, organizing, and lecturing along side with a few other graduate students.
basics of modeling in tinkerCAD (using native shapes, ruler, workplanes, grouping, subtractive grouping with empty objects, alignment)
the process of subtraction from a block to create a 2-part mold (bonus for alignment notches)
potential problems – overhangs/undercuts won’t let material release from mold
making model public, sharing, export for printing
have 3d printed molds prepared
the role of casting in re production and the greater level of autonomy it gives the maker (empploy much wider variety of materials than a 3d printer can print. Can make multiples much more quickly than printing, can make gang-molds to make for even greater numbers)
principles of casting (release, casting media[I’d suggest oogoo, gorilla glue+acrylic paint, or silicone caulking+dish soap, fidelity)
object cleanup (handling the seam/flash)
