S.A.M. Spring Aided Machining (CNC with solvent) is a school project designed by three architecture students at CCA, San Francisco: Matt Boeddiker, Abelino Robles, and Tim Henshaw-Plath. (www.cca.edu
) The machine is capable of rapidly prototyping and creating subtractive formwork that can be used to cast material. The machine was designed with the instruction of Jason Kelly Johnson, and Michael Shiloh in the Creative Architecture Machine class Fall 2013. Tecnically this is a transformative process where by material mass is maintained while volume is reduced ie a global increase in density.
